Common questions
Frequently Asked Questions
How do I calculate the cost of scope creep?
Multiply the extra hours by your hourly rate, then add any rush or priority-work premium. Also record the timeline impact. This calculator handles the arithmetic and gives you a clear change-order total.
Should I charge for small client changes?
If a request falls outside the agreed scope, price it even when the amount is small. You can choose to waive the fee, but documenting the value and schedule impact keeps expectations clear.
What is a reasonable rush fee for freelance work?
Rush fees often reflect the disruption caused by reprioritizing work, not only the hours involved. Choose a percentage that matches your availability, the deadline, and any impact on other commitments.
Does this calculator create a legally binding change order?
No. It creates an estimate to support a change request. A binding agreement depends on your contract, local law, and how the client accepts the change.
Is my project data uploaded or stored?
No. The calculation runs locally in your browser. ScopeYes does not receive or store the numbers you enter into this free calculator.
What should a freelance change request include?
Include the requested work, why it is outside scope, the additional price, any revised delivery date, and a clear approve-or-decline decision before work starts.
