Scope Creep Cost Calculator
Scope creep never feels like money leaving the room, because it never appears on an invoice. Put your real numbers in and it stops looking small.
What to do with that number
If the annual figure surprised you, the fix is rarely “be tougher” - it is having wording ready for the five or six moments where scope actually stretches, and a log where every addition gets an estimate attached to it. A request logged as “+4 hours” stops being a favour and becomes a decision the client makes knowingly.
We packaged exactly that as the Freelance Scope Creep Defense Kit - 7 ready-to-send scripts plus a Change Request Log template. The first script is readable in full on that page, so you can judge the wording before paying anything.
