Contractor vs Employee Cost

Reviewed 2026-08-28

Methodology and sources

This contractor-versus-employee planning result is derived only from the visible user-entered hourly rate, weekly hours, duration, salary, payroll-load, benefits, equipment, and user-supplied provenance fields. CostSignals does not fetch, validate, update, or endorse those entered assumptions or the calculated results.

Formula in plain English

The calculator multiplies entered contractor hourly rate by entered weekly hours, 4.333 weeks per month, and entered duration for contractor cost. It calculates employee cost as entered salary prorated by duration plus entered benefits, equipment, and entered payroll-load cost, then reports employee cost divided by modeled monthly contractor cost when hourly rate is positive and otherwise returns zero for the displayed ratio.

Visible assumptions

• Every monetary amount, ratio, and duration is user-entered. The required source name and YYYY-MM-DD source date, plus optional source URL, are provenance fields only and are not fetched, validated, refreshed, or endorsed by CostSignals.
• This calculator exposes no select fields or multiplier branches. Compatibility baseCosts values remain in the generated contract, but no output formula references them.
• breakEvenPoint is the selected-duration employee cost divided by modeled monthly contractor cost, so 4.500346180475421 means about 4.5 displayed employee-cost-equivalent contractor months for the entered scenario rather than a legal classification test or universal hiring break-even.
• recruitingCost aliases contractorCost, onboardingCost aliases employeeCost, and totalHiringCost aliases the higher of contractorCost and employeeCost for compatibility only; none is a separate hiring model.
• If hourly rate is zero, breakEvenPoint returns 0. If hourly rate is positive but weekly hours are zero, the denominator uses a max(1) guard and the displayed ratio becomes a finite formula sentinel rather than a meaningful month count.

Worked example

Limitations

• The calculator does not determine worker classification, legal status, tax treatment, benefits eligibility, recruiting plan, staffing strategy, vendor selection, current market pricing, or realized savings.
• The model excludes overtime rules, bonuses, overhead, management time, leave, insurance, recruiting fees, compliance costs, taxes beyond the entered load, and every other item not explicitly entered.
• The Department of Labor and Bureau of Labor Statistics sources provide classification and compensation-component context only; they do not support an entered rate, salary, benefits amount, payroll-load percentage, duration, savings claim, or modeled result.

Practical next steps

1. Document the exact source, date, units, and scope behind every entered contractor rate, salary, payroll-load, benefits, and equipment assumption.
2. Compare scenarios on identical duration, role scope, included overhead, and omitted-cost treatment before making a staffing decision.
3. Obtain legal, tax, HR, and compensation review outside this arithmetic worksheet before classifying a worker or acting on the comparison.
