Planning comparison only. Check estimates, omitted costs, timing, and constraints before making an operating decision.

Formula

Consulting fee formula

Consulting fee = labor fee + overhead + scope buffer + direct expenses - discount

Use scoped hours and a blended hourly rate for the same project, then keep overhead, buffer, expenses, and discounts separate.

Steps

  1. Enter the billable hours expected for the project scope.
  2. Enter the hourly or blended rate used to price the delivery work.
  3. Add direct expenses that should be included in the client-facing fee.
  4. Add overhead, scope buffer, and discount assumptions before comparing the effective hourly rate.

FAQ

Common questions

Is this the same as a freelance hourly rate calculator?

No. This calculator prices one fixed-scope consulting project. A freelance rate calculator works backward from income goals, billable days, expenses, and taxes.

Should direct expenses be marked up?

That depends on the contract and client expectation. If expenses are pass-through costs, keep them explicit. If you manage procurement risk, use overhead or scope buffer deliberately.

Why show the effective hourly rate?

Fixed project fees can look strong while hiding too many hours. The effective hourly rate helps compare the proposal against day-rate, retainer, and utilization targets.
