Find the rate you actually earned on a finished flat-fee job by dividing the fee by every hour you spent, including revisions and client admin. Compare that figure with your floor rate. The calculation stays in your browser.
The planned rate on a flat-fee job is the fee divided by the hours you estimated when you wrote the quote. The effective rate is the same fee divided by all the hours the job really took. If you spent 27 hours on the deliverable and another 6 on revision rounds and calls, a $3,000 fee paid $111.11 an hour on the core work. Include the unpaid 6 hours and the rate is $90.91. Against a $75 floor the job is still above the floor, but those unpaid hours erased $29.09 an hour from the planned $120 rate ($3,000 ÷ 25 hours).
Write unpaid time down for a few jobs and a pattern usually appears: the same kind of revision, the same kickoff calls, the same file export. You can put that pattern into the next quote as more estimated hours, a tighter revision limit, or a change-order price. This page will not tell you what the market pays, and it will not forecast income. It only divides the fee you already collected by the hours you enter.
If the job is still in progress, use the overrun calculator for hours already worked or the project overrun calculator to include time still ahead. To set a floor from your income goal and costs before you quote, use the freelance hourly rate calculator.
Default example: a $3,000 fee planned at 25 hours ($120.00/hr). Core work took 27 hours ($111.11/hr). Adding 6 unpaid hours makes 33 hours and an effective rate of $90.91/hr, which is still above a $75 floor. The fee would cover 40 hours at that floor.
The Rate Floor spreadsheet is a $12 one-time download. It helps you set a floor and check a flat-fee quote as hours come in, so the next project is priced from a number you have actually tested.

It is the fee divided by every hour the job actually took, including revisions, calls and admin you did not invoice separately. It is often lower than the planned rate, which only divides the fee by the hours you estimated up front.
Include any time you would have billed if the contract had been hourly: revisions beyond the plan, status calls, file wrangling and unpaid research. You can leave out general business admin that you would not charge to any one client.
It can show whether the last quote covered the time the job really took, at the floor you enter. It does not set a market rate or predict the next client's budget.
