How this calculation works
First find the invoicing needed after percentage fees to cover compensation and business expenses. Divide it by annual billable hours, which excludes nonbillable time through the chosen share. The compensation target is before personal taxes, not a calculated take-home salary.
Hourly invoice rate = (compensation + expenses) / [(1−fee) × work hours × weeks × billable share]A worked example
A target of 600,000 plus 120,000 expenses needs 800,000 invoicing after a 10% fee. Across 920 billable hours, the rate is about 869.57.
Good to know
A transparent arithmetic model using your inputs. Example prices, rates and multiples are demonstrations, not benchmarks or offers. No tax, exchange-rate conversion, live account access or automatic attribution is supplied. Monetary display is rounded; calculations retain additional precision.
Working hours and billable hours are not interchangeable
Administration, sales, learning and unpaid support can consume working time without appearing as invoiced hours. The billable share converts total working hours into the time expected to support the invoice target.
Weeks worked should exclude planned nonworking weeks. A full calendar year of hours can produce an unrealistically low required rate if holidays and unavailable periods are still treated as billable capacity.
A project quote adds job-specific cost and invoice-margin assumptions. An annual freelance-rate plan does not automatically cover every project’s scope or commercial risks.
A compensation target differs from an invoice target
Business expenses and percentage invoice fees must be covered before the modeled compensation remains. Grossing up for a fee is different from adding that same percentage to the desired net amount.
The compensation input is before personal taxes. This is a planning rate, not a market quote or a determination of what clients will pay. You can compare the result with actual demand and revise hours, expense assumptions or the target deliberately.
A few questions, answered
Does the rate include all taxes?
No. Personal tax and jurisdiction-specific rules are excluded.
Why does a smaller billable share raise the rate?
The same invoice target must be earned across fewer expected invoiced hours.
Can I use this for a fixed project quote?
It can inform a rate assumption, but project scope, delivery risk and direct costs need their own quote calculation.
