Freelance Rush Fee Required Rate Calculator
Work backward from the amount you need to keep on a rush assignment. Enter your target earnings, billable rush hours, extra rush-only costs, nonbillable coordination time, and normal hourly rate. The calculator returns the required billable rate, the implied rush premium, and an effective rate across all time. It makes the surcharge transparent before you quote the client.
Calculator
Rush quote targetFormula
Required rush rate = (target earnings + rush-only costs) ÷ billable hours. Rush premium = required rate ÷ normal rate − 1.
What the result means
Use the main result as a planning threshold under the assumptions entered. Secondary results explain the time, rate, revenue, or cost components behind that threshold.
Estimates are for planning only. Contract terms, local tax rules, actual expenses, and working conditions may produce different results.
Example calculation
To retain $1,500 from 12 billable hours with $100 of rush costs, quote at least $1,600, or $133.33 per billable hour. With 2 nonbillable hours, retained earnings equal $107.14 per total hour.
Tips for better results
- Use recent records instead of ideal estimates.
- Keep billable time separate from total time worked.
- Include project-specific costs before evaluating the result.
- Run a conservative scenario for uncertain workload or demand.
- Recalculate whenever scope, deadlines, fees, or expenses change.
Frequently asked questions
What does the required rush rate cover?
It covers target pre-tax earnings plus extra rush costs across the billable rush hours.
How is the rush premium comparison calculated?
The required billable rate is compared with the normal hourly rate you enter.
Why include nonbillable coordination time?
It lowers effective earnings per total hour even though it is not included in the quoted billable rate.
Can the calculated premium be negative?
Yes. That means the normal rate already exceeds the minimum rate required by these inputs.
Does the target earnings amount include tax?
No. The target is before tax; add tax planning separately if needed.
