Legal Cost Methodology & Evidence Limits
An evidence-limited editorial inventory of source references, assumptions, and formula summaries for legal, shown separately from the canonical public calculator catalog.
Methodology Overview
The canonical public catalog currently contains 348 legal calculator pages across 13 categories. Separately, this page inventories 82 resolved editorial methodology records: 74 resolve to current canonical public configs and 8 remain internal or unlinked. The records contain 238 declared source references. These references are raw editorial declarations, not item-level citations, license evidence, or proof that a source is linked to a calculator's runtime formula. Raw editorial records that do not resolve to a calculator config are excluded from these totals. No catalog-wide accuracy range, validation dataset, or portfolio refresh cadence is asserted here. Use calculator outputs as planning scenarios and compare them with current local quotes and requirements.

Calculation Approach
Calculator contracts vary by page. The following steps explain how to interpret common patterns without implying that every calculator uses the same inputs, sources, or adjustments:
- 1Input basis — A calculator may start from configured defaults, user-provided values, or both. A base value should be treated as source-verified only when that calculator provides item-level provenance.
- 2Quantity and specification inputs — Where exposed, inputs may include project dimensions, material choices, complexity factors, and other variables specific to the user's situation.
- 3Runtime calculation — Each calculator applies its own configured arithmetic. An editorial formula summary may be incomplete or differ from runtime behavior until the item is reviewed and linked directly to its implementation.
- 4Location handling — Location factors apply only where a calculator has them configured and available. Accepting a ZIP code does not, by itself, certify that the displayed price reflects current local market data.
- 5Range output — Low–high results reflect the calculator's configured arithmetic and assumptions. They are not an observed distribution of contractor quotes unless a calculator explicitly documents such a dataset.
Category Breakdown
This page groups editorial methodology records into 14 categories. The separate canonical public catalog contains 348 legal calculator pages. Of the 82 editorial records below, 74 resolve to current public configs and 8 do not. The entries reproduce declared references, assumptions, and formula summaries; they do not establish item-level source-to-formula provenance.
Personal Injury42 documented records
This category contains 42 editorial records; 37 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- Administrative Office of the U.S. Courts civil-case overview for general process context; it supplies no liability, damages, percentage, cap, or outcome
- American Academy of Orthopaedic Surgeons (AAOS) ankle injury treatment protocols and cost benchmarks
- American Academy of Orthopaedic Surgeons (AAOS) knee injury surgical outcome and cost data
- American Academy of Orthopaedic Surgeons (AAOS) shoulder injury treatment cost and outcome data
- American Academy of Orthopaedic Surgeons (AAOS) treatment cost data by fracture type
- American Academy of Orthopaedic Surgeons (AAOS) treatment cost data for spinal conditions by severity
- American Association of Neurological Surgeons (AANS) cervical spine injury treatment cost data
- American Association of Neurological Surgeons (AANS) published treatment guidelines and outcome statistics
Declared Assumptions
- The trucking company carried the federally mandated minimum liability insurance or higher
- Federal Hours of Service and inspection regulations were applicable at the time of the accident
- Severity of injuries tends to be higher in truck crashes due to the mass differential between commercial trucks and passenger vehicles
- The property owner or occupier owed a legal duty of care to the injured person (invitee, licensee, or trespasser status may affect this)
- The hazardous condition existed long enough for the owner to have discovered and remedied it through reasonable diligence
- Comparative fault principles apply; the claimant's own actions (e.g., ignoring warning signs) may reduce recovery
Editorial Formula Summary
Calculates a settlement range by combining economic damages with a severity multiplier adjusted upward for the unique factors in commercial trucking cases, including higher policy limits, federal regulatory violations, and the typically greater force of impact in truck collisions.
Employment Law10 documented records
This category contains 10 editorial records; 10 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- 29 U.S.C. § 2617 — civil remedies, equitable relief, fees/costs, and limitations
- American Bar Association survey data on employment litigation outcomes
- Bureau of Labor Statistics (BLS) overtime and wage compliance statistics
- Bureau of Labor Statistics job search duration data for mitigation calculations
- Bureau of Labor Statistics median wage data by occupation and industry
- Bureau of Labor Statistics wage data for comparable position calculations
- Department of Labor Wage and Hour Division enforcement statistics and recovery data
- EEOC (Equal Employment Opportunity Commission) charge statistics and resolution data
Declared Assumptions
- The employee filed a timely charge with the EEOC or state equivalent within the required deadline (180 or 300 days)
- Federal damage caps apply: $50K (15-100 employees) to $300K (500+ employees) for compensatory and punitive damages combined under Title VII
- State law claims may not have damage caps and can significantly increase recovery
- The Fair Labor Standards Act (FLSA) requires time-and-a-half for hours over 40 per week for non-exempt employees
- Liquidated damages under FLSA equal 100% of unpaid wages (effectively doubling the recovery) unless the employer proves good faith
- State wage laws may provide additional penalties, longer statutes of limitation, or broader coverage
Editorial Formula Summary
Estimates potential settlement ranges for employment discrimination claims by summing economic damages (back pay, front pay, lost benefits) and non-economic damages (emotional distress, humiliation, reputational harm). Federal anti-discrimination statutes (Title VII, ADA, ADEA) impose damage caps based on employer size.
Damages Helpers8 documented records
This category contains 8 editorial records; 8 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics for median earnings by occupation
- Bureau of Labor Statistics Occupational Employment and Wage Statistics
- Bureau of Labor Statistics medical care consumer price index for cost projection and inflation adjustment
- CMS physician fee schedule for procedure cost estimation
- Department of Labor work-life expectancy tables by age and gender
- Economic loss publications from the National Association of Forensic Economics
- Exposed jury verdict databases for settlement ranges by injury type and fault allocation
- Healthcare Cost and Utilization Project (HCUP) national inpatient and emergency department cost data by procedure and diagnosis
Declared Assumptions
- Wage documentation (pay stubs, tax returns, employer verification) is available to substantiate claimed earnings
- Self-employed claimants can demonstrate lost income through business records and tax filings
- Future lost earning capacity projections assume reasonable mitigation (i.e., the claimant returns to work when medically cleared)
- The treating physician has documented the need for ongoing or future medical treatment
- Medical cost inflation is factored at a rate consistent with historical healthcare CPI trends
- Present-value discounting uses a conservative rate reflecting current economic conditions
Editorial Formula Summary
Calculates economic damages for lost income by multiplying the claimant's daily wage rate by the number of workdays missed due to injury. Future lost earning capacity is projected using age, occupation, and remaining work-life expectancy data, then reduced to present value.
Medical Negligence7 documented records
This category contains 7 editorial records; 7 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- AHRQ (Agency for Healthcare Research and Quality) Patient Safety Indicators for surgical adverse events
- AHRQ Hospital Survey on Patient Safety Culture
- American College of Obstetricians and Gynecologists (ACOG) clinical guidelines on standard-of-care during labor and delivery
- American Dental Association (ADA) treatment cost benchmarks for corrective procedures

- CMS (Centers for Medicare & Medicaid Services) Hospital Compare quality data
- Centers for Disease Control and Prevention (CDC) birth defect and birth injury prevalence statistics
- Centers for Medicare & Medicaid Services (CMS) nursing home deficiency citation data
Declared Assumptions
- A qualified medical expert is available to testify that the healthcare provider deviated from the standard of care
- The injury is directly attributable to the deviation rather than to the underlying medical condition
- State damages caps, if applicable, may limit non-economic or total recovery regardless of the estimated range
- Corrective treatment costs include all procedures needed to restore the patient to pre-malpractice condition
- Nerve damage (inferior alveolar or lingual nerve) significantly increases settlement value due to permanent numbness or pain
- Expert testimony from a board-certified dentist is typically required to establish the standard of care
Editorial Formula Summary
Produces an educational settlement range by combining the cost of corrective medical treatment, lost wages, and non-economic damages. The estimate accounts for the complexity of proving a deviation from the accepted standard of care and any state-imposed damages caps.
Other2 documented records
This category contains 2 editorial records; 2 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- American Association for Justice case outcome reports
- Exposed jury verdict and settlement data aggregated from public court filings across 50 states
- Insurance Information Institute (III) reported average bodily injury claim payouts
- National Highway Traffic Safety Administration (NHTSA) crash cost studies
- Published jury verdict reporters and settlement databases used by insurance adjusters
Declared Assumptions
- The claimant is not primarily at fault under the applicable comparative negligence standard
- Medical treatment was sought promptly and documented consistently by licensed providers
- Insurance policy limits are sufficient to cover the estimated range; actual recovery may be capped by available coverage
- The multiplier method is a widely-used insurance industry heuristic, not a statutory formula
- Medical bills used as the base reflect reasonable, necessary treatment as documented by healthcare providers
- Some insurers use a per-diem method instead of or alongside the multiplier approach; this tool focuses on the multiplier model
Editorial Formula Summary
Estimates a potential settlement range by summing documented economic damages (medical expenses, lost wages, property damage) and applying a severity-adjusted multiplier for non-economic damages such as pain and suffering. The multiplier is selected based on injury severity, treatment duration, and recovery prognosis.
Workers Compensation2 documented records
This category contains 2 editorial records; 2 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- American Medical Association Guides to the Evaluation of Permanent Impairment (5th and 6th editions) rating schedules
- Bureau of Labor Statistics (BLS) occupational injury and illness data
- National Academy of Social Insurance (NASI) annual workers' compensation data report
- National Council on Compensation Insurance (NCCI) workers compensation benefit data by state
- State workers' compensation commission published benefit rate tables
- Workers Compensation Research Institute (WCRI) published settlement and benefit outcome studies across 18 major jurisdictions
Declared Assumptions
- The injury arose out of and in the course of employment, meeting the statutory requirements for compensability
- The employer carried active workers' compensation insurance at the time of the injury
- Benefit rates are based on the state where the injury occurred; multi-state employment situations may have different rules
- Impairment rating is assigned by a licensed physician after the injured worker reaches maximum medical improvement (MMI)
- Permanent partial disability benefits are calculated as a percentage of the state average weekly wage multiplied by the impairment rating
- Lump-sum settlement value is typically 60-80% of the projected total benefits to account for time value and litigation risk
Editorial Formula Summary
Estimates weekly wage replacement benefits and potential permanent impairment awards by applying the state-specific compensation rate to the claimant's average weekly wage. Temporary total disability benefits are typically two-thirds of the pre-injury average weekly wage, subject to statutory minimums and maximums.
Legal Planning2 documented records
This category contains 2 editorial records; 0 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- American Chiropractic Association treatment cost benchmarks for whiplash recovery
- Exposed jury verdict data aggregated from public court filings for whiplash-specific claims
- Insurance Research Council (IRC) closed-claim studies for soft-tissue cervical spine injury payouts
- National Library of Medicine MedlinePlus neck-injury information for the medical-evaluation boundary; it supplies no diagnosis, causation, prognosis, treatment, damages, or legal value
- User-entered records and allowances reviewed for one documented scenario
Declared Assumptions
- The claimant sought medical attention within 72 hours of the accident, establishing a clear causal link
- Treatment was consistent and documented — gaps in treatment reduce settlement value significantly
- No pre-existing cervical spine condition complicates causation analysis
- Every amount, percentage, and cap is entered by the user and starts at zero
- No jurisdiction, fault, injury, case-strength, multiplier, policy-limit, or legal-rule conclusion is supplied
- The arithmetic result is not a claim value, settlement prediction, judgment, entitlement, or advice
Editorial Formula Summary
Estimates whiplash injury settlement ranges by summing documented medical expenses (ER visit, imaging, chiropractic care, physical therapy) and lost wages, then applying a severity multiplier of 1.5–5× based on treatment duration, symptom persistence, and whether the injury caused chronic pain or required injections.
Mass Tort2 documented records
This category contains 2 editorial records; 2 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- FDA Adverse Event Reporting System (FAERS) data for GLP-1 receptor agonist gastroparesis reports by drug and outcome severity
- FDA pregnancy category guidance and updated labeling history for acetaminophen products
- JAMA Psychiatry and BMJ meta-analyses on prenatal acetaminophen exposure and neurodevelopmental outcomes
- MDL 3043 (S.D.N.Y.) — multidistrict litigation status and bellwether selection criteria
- MDL No. 3094 (Northern District of Ohio) GLP-1 gastroparesis litigation case criteria and bellwether selection factors
- Published gastroenterology research on GLP-1 agonist effects on gastric motility and gastroparesis risk factors
Declared Assumptions
- GLP-1 medications under litigation include semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro), dulaglutide (Trulicity), liraglutide (Victoza, Saxenda)
- Stronger cases involve gastroparesis diagnosis confirmed by gastric emptying study (gold standard) rather than clinical symptoms alone
- Symptom onset during or within 6 months of GLP-1 use strengthens causal connection; pre-existing gastroparesis weakens claims
- Studies show a 20-30% increased risk of ASD/ADHD with sustained prenatal acetaminophen use, but individual causation must be proven
- Retailer and manufacturer defendants face different liability theories (failure to warn vs. product liability)
- MDL consolidation means bellwether trial outcomes will influence global settlement values
Editorial Formula Summary
Screens potential GLP-1 gastroparesis claims by evaluating medication history (specific drug, dosage, duration of use), symptom onset timing relative to drug initiation, diagnosis confirmation (gastric emptying study, clinical evaluation), severity of complications, and current treatment costs. Provides a preliminary eligibility assessment based on published litigation criteria.
Product Liability2 documented records
This category contains 2 editorial records; 2 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- CPSC (Consumer Product Safety Commission) recall and injury data
- Jury verdict databases for airbag product liability cases
- NHTSA complaint database and recall data for airbag defect patterns
- Product liability settlement databases from major mass tort tracking services
- Published jury verdicts in product liability litigation
- Takata airbag recall settlement trust data and individual claim outcomes
Declared Assumptions
- Strict product liability applies in most states — the manufacturer is liable for defective products regardless of negligence
- Takata airbag cases have an established claims process through the bankruptcy trust; non-Takata cases proceed as individual product liability claims
- Airbag deployment failures in survivable crashes create strong liability evidence because the airbag is expected to function in precisely those conditions
- The product was used in a reasonably foreseeable manner (including foreseeable misuse)
- A causal link between the product defect and the injury can be established through expert testimony
- Strict liability, negligence, and breach of warranty theories are all potentially available depending on jurisdiction
Editorial Formula Summary
Estimates potential recovery for airbag defect claims based on injury severity, defect type (failure to deploy, late deployment, excessive force, Takata recall), medical costs, and applicable strict product liability theories. The screener applies historical settlement data from airbag-related product liability cases.
Statute of Limitations1 documented record
This category contains 1 editorial record; 0 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- Consumer Product Safety Commission (CPSC) injury and recall data
- Exposed jury verdict databases for product liability settlements by product category
- Insurance Information Institute (III) product liability claim statistics
Declared Assumptions
- Strict liability applies: the plaintiff must prove the product was defective (design, manufacturing, or warning defect) and caused the injury
- Multiple parties may be liable in the distribution chain: manufacturer, distributor, retailer
- Product recalls and prior complaints strengthen the case significantly
Editorial Formula Summary
Estimates settlement ranges for defective product injury claims under strict liability, negligence, or breach of warranty theories. Sums medical costs, lost wages, and property damage, then applies severity multipliers. Product liability claims do not require proving the manufacturer was negligent — only that the product was defective and caused injury.
Consumer Protection1 documented record
This category contains 1 editorial record; 1 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- FTC Used Car Rule and Magnuson-Moss Warranty Act provisions for used vehicle claims
- National Highway Traffic Safety Administration (NHTSA) vehicle complaint database
- State-specific lemon law statute requirements (repair attempts, days out of service triggers)
Declared Assumptions
- Most state lemon laws require 3-4 repair attempts for the same defect OR 30+ cumulative days out of service within the warranty period
- Usage offsets (mileage deductions from refund) are calculated as: purchase price × (miles at first repair / 120,000)
- Manufacturer attorney fee liability (prevailing consumer recovers fees) significantly affects settlement dynamics
Editorial Formula Summary
Estimates potential recovery under state lemon law statutes by evaluating the vehicle purchase price, number and nature of repair attempts, days out of service, and whether the manufacturer met its obligation to repair, replace, or refund. Models outcomes including vehicle replacement, full refund minus usage offset, and manufacturer buyback.
Social Security1 documented record
This category contains 1 editorial record; 1 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- SSA annual statistical supplement for average SSDI benefit amounts by age and gender
- SSA disability determination statistics (approval rates by age, condition, and stage of appeal)
- Social Security Administration SSDI benefit calculation formula and current bend points
Declared Assumptions
- SSDI benefits are based on your earnings record — higher lifetime earnings result in higher benefits (max approximately $3,822/month in 2026)
- There is a mandatory 5-month waiting period from disability onset to benefit eligibility
- Back-pay can cover up to 12 months before the application date (total potential back-pay of 17+ months)
Editorial Formula Summary
Estimates monthly Social Security Disability Insurance (SSDI) benefits based on your Average Indexed Monthly Earnings (AIME), applying the Social Security bend-point formula to compute the Primary Insurance Amount (PIA). Models the 5-month waiting period and potential back-pay calculation.
Insurance Claims1 documented record
This category contains 1 editorial record; 1 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- National Association of Insurance Commissioners (NAIC) consumer complaint data
- Published jury verdicts in bad faith insurance litigation across multiple states
- State insurance department enforcement actions and penalty data
Declared Assumptions
- The insurer had an obligation to pay or investigate the claim in good faith under the insurance contract and state regulations
- The insured can demonstrate the insurer acted unreasonably in denying, delaying, or underpaying the claim
- State-specific bad faith statutes and remedies apply (first-party vs. third-party bad faith)
Editorial Formula Summary
Estimates bad faith insurance claim value by calculating the underlying claim value that was wrongfully denied or underpaid, consequential damages caused by the denial (additional debt, lost property, credit damage, medical complications from delayed treatment), emotional distress damages, and potential punitive damages based on the insurer's conduct. Punitive damages in egregious cases can be 2-10x compensatory damages depending on state law and insurer conduct.
Construction1 documented record
This category contains 1 editorial record; 1 resolve to current canonical public calculator configs. This inventory is not item-level provenance. Confirm source freshness and runtime formula linkage before relying on these declarations.
Declared Source References (editorial inventory)
- Construction Defect Liability Reporter case law and settlement data
- National Association of Home Builders warranty claim and construction defect survey data
- RSMeans construction cost estimation data for remediation pricing
Declared Assumptions
- The defect is attributable to construction workmanship, design, materials, or code compliance rather than normal wear and age
- Notice requirements and right-to-repair statutes applicable in the jurisdiction have been satisfied
- Statute of repose has not expired (varies by state, typically 6-12 years from substantial completion)
Editorial Formula Summary
Estimates construction defect claim value by evaluating the defect category (structural, water intrusion, electrical/plumbing, material, or code violation), repair or remediation costs, diminished property value, loss of use during repairs, temporary housing costs, and consequential damages (mold growth, personal property damage). Construction defect claims may be brought against builders, developers, subcontractors, architects, engineers, and material suppliers.
Regional Adjustments
Legal costs can vary by location because labor, materials, fees, availability, and market conditions differ. The size and direction of that effect depend on the calculator and the actual project; this page does not publish a universal city-to-city multiplier.
Some calculators may apply stored location factors when they are configured and available. A ZIP-code or city field is not proof of current local-price coverage, and this inventory does not verify a common location dataset across the catalog. Validate planning results with current local bids, permit rules, professional fees, and other requirements relevant to the project.
Update Status & Evidence Limits
Refresh status: This inventory does not verify a portfolio-wide quarterly or interim refresh cadence. Source age and review status must be established at the individual calculator and source level.
Source validation: Multiple source names in an editorial block do not prove independent validation, licensing, freshness, or runtime use. Those checks require traceable source URLs, access dates, and formula linkage for each calculator.
Accuracy evidence: We do not publish a universal empirical error band for this catalog because a representative validation dataset is not available on this page. Actual quotes and outcomes can differ materially from a planning estimate.
