Scope Leak Calculator | Free Fixed-Price Project Tool

A client asks for another page, revision, or task. Before you agree, see what the extra work does to the profit on your fixed-price project.

Enter your project fee, planned hours, loaded hourly cost, other planned costs, and one extra request. The editable calculator shows your original and revised gross profit and margin. It also gives two fee reference points: one that keeps your original profit amount and one that keeps your original margin percentage.

This free download includes Scope-Leak-Calculator.xlsx and a one-page Quick-Start.pdf with a worked example. Change the yellow cells to use your own project numbers. No macros or account connection are needed. Use the same currency for every amount in a project.

The figures support a commercial decision; they do not determine what your agreement includes or guarantee payment. Gross margin excludes taxes and costs you do not include in the project inputs.
