Methodology and sources

This CDN planning result is derived only from the visible user-entered bandwidth, request volume, fixed-fee, and user-supplied source fields. CostSignals does not fetch, validate, update, or endorse those entered source details.

Planning answer

This page answers what the entered inputs produce under the calculator's documented assumptions. It does not answer what a local provider will charge, approve, diagnose, finance, or guarantee.

Use the result to compare like-for-like scenarios, then replace placeholders with current project records, bids, supplier quotes, authority requirements, or qualified professional review before acting.

Formula in plain English

The calculator multiplies the entered bandwidth volume by the entered bandwidth rate, converts entered request volume to millions and multiplies it by the entered request rate, then adds the entered fixed monthly fee to show the modeled monthly CDN cost.

Visible assumptions

  • Every numeric rate and quantity begins at zero until the user enters it, so the model never inserts a hidden bandwidth rate, request rate, fixed fee, or traffic amount.
  • The visible region and provider selections are neutral multiplier-1 labels in the current runtime and do not change the arithmetic.
  • The named source and source date document where the user obtained the entered assumptions; they are required provenance fields, not validated provider pricing.
  • Deprecated MRR-named outputs are compatibility aliases for bandwidth cost, request cost, and total monthly cost; they do not add a revenue model.

Worked example

Example entered CDN scenario

  • 10,000 entered GB at $0.05 per GB
  • 5,000,000 entered requests at $0.75 per million requests
  • $100 entered fixed monthly fee with a documented source name and date

Bandwidth cost = 10,000 x $0.05 = $500. Request cost = 5,000,000 / 1,000,000 x $0.75 = $3.75. Total monthly cost = $500 + $3.75 + $100 = $603.75.

The modeled planning total is $603.75 per month for this entered CDN scenario only; it is not a provider quote, performance claim, or vendor recommendation.

Limitations

  • The calculator does not choose a provider, quote a service, rank vendors, predict savings, or conclude that one delivery design, latency profile, security posture, privacy approach, or compliance approach is preferable.
  • The model excludes cache-hit behavior, shielding, origin transfer, log delivery, WAF, media services, support, tax, and contract items that are not explicitly entered.
  • The cited NIST CDN source supports general CDN context only and does not support bandwidth or request rates, a fixed fee, provider selection, performance outcome, or modeled cost.

Practical next steps

  1. Document each entered bandwidth, request, and fixed-fee assumption with a named source and source date.
  2. Normalize compared scenarios on the same traffic units, feature scope, and omitted cost categories.
  3. Review separate delivery, privacy, operational, and contract considerations outside this arithmetic worksheet before choosing a service.

CDN Cost Estimator FAQs

Treat the result as a planning scenario calculated from the values you enter and the configured formula. It is not a vendor quote, market comparison, or promise of price, scope, timing, or outcome.
Confirm scope, units, volumes, service levels, fees, and contract terms against your requirements and itemized vendor materials. Keep the same definitions when comparing scenarios.
Request a dated written quote that identifies licensing, implementation, support, usage, renewal, taxes, and exclusions. Enter comparable values into the calculator and resolve material differences with the vendor.
