Weekly Retainer Calculator

How this calculator works

This tool is designed for freelancers, consultants and agencies that sell professional time or fixed-scope work. Pricing fails when working hours are treated as billable hours or when overhead and revision risk are ignored. Target price = estimated delivery cost ÷ (1 − target margin).

Use the right inputs

Use figures from the same time period and the same cost definition. Required inputs on this calculator are Expected weekly service hours, Effective hourly cost, Weekly direct costs, Target margin. If an amount already includes overhead or employer burden, do not add the same cost again elsewhere.

How to interpret the result

The result is decision support, not a universal target. Use the result as a floor or planning reference, then apply scope, risk, positioning and client value separately. A change in one assumption can materially change the answer, especially when margin or billable utilization is involved.

Common mistake

Copying a market rate without calculating your own cost and capacity can produce a price that looks normal but is commercially unsustainable.

Decision checklist

• Make sure every input covers the same period or project.
• Use actual hours and costs when they exist; label estimates as estimates.
• Re-run the calculator when scope, price, cost or capacity changes.
• Keep the result together with the assumptions that produced it.

Limitations

SheryPro does not infer taxes, employment classification, legal fee rules, contract language, client demand or jurisdiction-specific requirements. The calculator uses only the inputs shown. Changing third-party pricing is sourced and dated where a provider-specific figure is used.
