Scope Creep Cost Calculator
This scope creep cost calculator shows how unpaid or underpriced extra work affects your effective hourly rate, profit, and overall project margin. It’s designed for freelancers, consultants, and agencies pricing fixed-scope work.
Impact model: Extra hours lower your effective hourly rate because the same project price is spread across more total hours. Profit drops when added hours increase costs without increasing revenue.
Original effective hourly rate: $
New effective hourly rate: $
Lost revenue value: $
Estimated profit loss: $
Even small amounts of scope creep can dramatically reduce profit and undermine project pricing.
