How to use
- Enter Extra hours.
- Enter Hourly rate.
- Calculate, then review the period, scope and assumptions before using the result for pricing or planning.
How it is calculated
Scope creep cost = extra hours × hourly rate
Example
Fifteen extra out-of-scope hours at 100 per hour represent an arithmetic cost of 1,500 before any additional margin or change fee.
Important notes
This calculator does not determine whether the hours are billable; enforceability of change charges depends on contract, approvals and scope documentation.

Frequently asked questions
Should a margin be added on top?
If your change policy includes an extra fee or margin, apply it according to the contract; this formula only calculates hours × rate.
Is the result a mandatory client price?
No. It is a planning result from your inputs; final pricing depends on scope, market, contract, taxes and risk.
Should I use monthly or annual figures?
Keep all inputs on the same period so annual income is not mixed with monthly hours or expenses.
