What is a free scope creep, and what goes on one?
The scope creep calculator quantifies the cost of out-of-scope work. Input the original scope, additional requests, and your rate to see exactly how much the scope creep is costing you.
Key components
- Original scope hours — what was agreed in the contract.
- Additional hours — time spent on out-of-scope requests.
- Cost of scope creep — the dollar value of the extra work.
- Change order template — a formal request for additional payment.
How to use this tool
- Enter the original project fee and estimated hours.
- Input the additional hours caused by client revisions or new requests.
- Review the cost of the extra work.
- Use the data to justify a change order or additional invoice.
Why this matters
Scope creep silently destroys profitability. Seeing the actual dollar amount of 'just one more quick edit' gives you the courage to enforce your boundaries and charge for out-of-scope work.
