Hong Life CalculatorsUnderstanding the extra revisions fee calculator — concept and principle
Designers, writers, developers and other creative professionals usually include a fixed number of revision rounds in a quote. When a client asks for more, the extra work should be billed. This calculator works out how many revision rounds go beyond the agreed number and what to charge for them, so you can quote the additional fee quickly and consistently.
How it is calculated
- Extra revisions = max(0, revisions requested − revisions included)
- Additional fee = extra revisions × hours per revision × hourly rate
If the client uses fewer revisions than included, the result is zero rather than a credit. Hours per revision is your average time for one round, including reading feedback, making changes and sending the new version. The calculator shows USD by default but works with any currency.
The principle
The original price already pays for the included rounds, so only the rounds above that limit create new, unpaid work. Each extra round is valued at the time it takes multiplied by your rate, the same way hourly work is billed. Setting the floor at zero reflects how most contracts work: included revisions are an allowance the client may use, not a prepaid amount that is refunded when unused.
Worked example
- Inputs: 2 revisions included, 5 requested, 1.5 hours per revision, $60 per hour.
- Extra revisions: 5 − 2 = 3.
- Hours to bill: 3 × 1.5 = 4.5 hours.
- Additional fee: 4.5 × 60 = $270.00.
How to read the result
The fee is a fair benchmark when each round is similar in size. Late-stage revisions are often small tweaks, while a change of direction can be closer to new work; in that case quote it as a change request rather than a revision. Telling the client the fee before starting the extra round avoids disputes and often leads to clearer, consolidated feedback.
Common mistakes
- Not defining in the contract what counts as one revision round.
- Charging for rounds caused by your own errors.
- Underestimating hours per revision by leaving out communication and file preparation.
- Billing extra rounds without telling the client in advance.
Frequently asked questions
How many revisions should a quote include?
There is no rule. Many professionals include two or three rounds and state the rate for additional rounds in the proposal.
Should extra revisions cost more than my normal rate?
Some charge a premium for rushed or out-of-scope work. Whatever you choose, write it into the agreement before work begins.
What if the client changes the brief entirely?
That is usually a scope change, not a revision. Re-quote the new work instead of counting it as a round.
