Why scope creep quietly kills your income

Scope creep is the slow expansion of a project beyond what you agreed to bill for — an "extra" page, a fourth round of revisions, a "quick" favour. Each one feels small, but together they lower the real rate you're earning on the whole project. Six unpaid hours at a $60 rate is $360 of your time given away, and it drags your effective project rate down with it.

This calculator puts a number on it. Enter your rate and the extra hours, and optionally the project price, to see the value of the unpaid work, what your effective hourly rate becomes once you include it, and what share of the project you're now doing for free.

How to prevent scope creep

Frequently asked questions

What counts as scope creep?

Any work beyond what you originally quoted — extra deliverables, additional revision rounds, "quick" favours, or a project that keeps growing without a new agreement.

How do I charge for scope creep?

Treat new requests as change orders: give a short quote for the extra work before doing it. This calculator shows the value of what you'd otherwise give away for free.

How much scope creep is normal?

A little flexibility builds goodwill, but if unpaid extras regularly reach 10–20% of a project, your effective rate is dropping meaningfully and it's time to tighten your contract.
