Freelance Project Timeline & Revenue Calculator
Turn an estimated project size and your weekly billable capacity into a delivery timeline, total fee and the monthly run-rate that project implies.
How it works
Weeks = hours ÷ weekly hours · Fee = hours × rate · Weekly run-rate = weekly hours × rate · Annualised = weekly run-rate × 52
A fixed project fee only tells half the story — what matters to your calendar is how many weeks of capacity it consumes. Dividing the estimated hours by the billable hours you can commit each week gives the delivery timeline, and multiplying your weekly billable hours by your rate reveals the run-rate that project sustains. Comparing the annualised run-rate against your income goal shows whether a project is worth the calendar space it takes.
Worked example
A 120-hour build at $85/hr is a $10,200 fee. At 25 billable hours a week it fills about 5 weeks (120 ÷ 25 = 4.8, rounded up). Those 25 hours a week earn $2,125, an annualised run-rate of roughly $110,500 if you stayed that booked all year.
Frequently asked questions
Should I quote a fixed fee or hourly?
Estimate the hours either way. A fixed fee protects the client from overruns but shifts the risk to you, so pad your hour estimate for scope creep. This calculator converts between the two so you can quote a fixed number while still seeing the effective hourly rate behind it.
Why look at a weekly run-rate?
A large total fee can still be a poor use of time if it stretches over many weeks at a low weekly rate. The weekly run-rate lets you compare a $10,000 six-week project against a $6,000 two-week project on equal footing.
What billable hours per week is realistic?
Full-time freelancers rarely bill 40 hours — 25 to 30 billable hours a week is common once you account for admin, sales and breaks. Use your honest sustainable number, not your maximum.
