Frequently asked questions
What is scope creep in freelancing?
Scope creep is when work expands beyond the agreed scope without a matching price increase — 'can you also just fix the footer?', one more revision round, a 'quick' feature that takes a day. Individually each request seems small; collectively it can cut your effective hourly rate by 20–40%.
How do I calculate the cost of scope creep?
Estimate the hours the extra work took (or will take), multiply by your hourly rate, and compare the resulting effective rate against what you agreed. This calculator walks through that math and shows the lost earnings per project and per year.
How do I stop a client from creeping scope?
Three levers: a written scope with an explicit exclusions list, a change-request process ('that's outside scope — here's the cost and timeline to add it'), and a small buffer (10–15%) built into your quote. Polite scripts beat confrontations — the calculator includes language you can send as-is.
