Catch the next one earlier
This tool handles one change request. The full kit helps reduce scope confusion before kickoff.
Use the workflow kit to confirm scope, assets, approvals, revisions, payments, and change-request language before the project starts.
When to use this calculator
Use it when a client asks for something that may affect scope, budget, or timing. It is best for one request at a time.
What it does not do
It does not know your contract, taxes, platform fees, client history, or exact availability. Treat the output as a draft estimate.
What to do next
Confirm the change in writing before starting. If this happens often, use a reusable tracker and change-request process.
Scope creep cost example: adding a blog section
Sample scenario, not a customer result: a $2,000 website was estimated at 20 hours. A new blog section adds 8 delivery hours and 1 admin hour. The freelancer enters a $100 hourly rate, normal urgency and a 2-business-day delay.
9 extra hours; suggested $900 fee
8 delivery hours + 1 admin hour = 9 hours. At normal urgency, 9 × $100 = a suggested $900 change-request fee. Taxes, platform fees and contract terms are not included.
About a 31% hourly rate drop
The original effective rate is $2,000 / 20 = $100 per hour. If the additional work is unpaid, $2,000 / 29 = $68.97 per hour. The decrease is about 31%; it is not a 31% reduction in the project fee.
2 days entered, not predicted
The timeline result repeats the delay you enter. Confirm availability, approvals and dependencies with the client before agreeing to a new delivery date.
How the suggested fee is calculated
Extra delivery and admin hours are added together, then multiplied by your hourly rate and the selected urgency factor: normal 1, rush 1.25, or urgent 1.5. If no hourly rate is entered, the tool uses project fee divided by original estimated hours. These urgency factors are tool assumptions, not industry standards.
For positive extra hours, the estimate has a half-hour minimum at your base rate. It rounds up to the next $10 below $100, or the next $25 at $100 and above. An included-revision classification displays no added fee. Missing inputs can prevent an estimate. Review the classification and your agreement before quoting.
What should I say when a client requests extra work?
Sample wording: "Thanks for the request. The blog section is outside the agreed website scope. My suggested estimate is $900 for 9 additional hours, with 2 extra business days. Please confirm the added fee and revised timeline before I begin." Adapt this wording to the actual scope and agreement; the tool also drafts a reply from your inputs.
Is scope creep always billable?
No. Included revisions or work already agreed in your scope may not justify an added charge. Clarify uncertain requests first. Use the free client onboarding checklist to define revision and change-request boundaries earlier, or the client reply generator to draft a clarification.
