Billable hours for freelancers: calculate capacity before setting a rate
Build a realistic weekly capacity example, distinguish billable work from unpaid work and calculate the rate needed under your own assumptions.
Available working time is not the same as time you can invoice. Start with a time budget that includes the work you must do even when it cannot be charged to a client. The numbers below are a planning exercise, not a promise of earnings.
Subtract the work that cannot be invoiced
Suppose a freelancer allocates 40 working hours a week. In this example, sales takes five hours, administration three, training two and unallocated time four. That leaves 26 hours available for approved client work.
| Activity | Hours | Invoice to the client in this example? |
|---|---|---|
| Sales and proposals | 5 | No |
| Administration | 3 | No |
| Training | 2 | No |
| Unallocated time | 4 | No |
| Approved client work | 26 | Yes |
| Total | 40 | 26 billable hours |
Use working weeks, not all weeks by default
Assume 46 working weeks in the year. At 26 billable hours each week, annual billable capacity is 1,196 hours. Using 40 × 52 would instead assume 2,080 billable hours and ignore every deduction in the example.
To reach an illustrative gross billing target of USD 71,760 across 1,196 billed hours, the required average collected rate is USD 60 per hour. This is not take-home income: business costs, fees, tax and unpaid invoices are not deducted in that target.
| Step | Calculation | Result |
|---|---|---|
| Annual billable capacity | 26 × 46 | 1,196 hours |
| Illustrative annual billing target | Assumption | USD 71,760 |
| Required average collected rate | 71,760 ÷ 1,196 | USD 60/hour |
Keep the agreement and your time record aligned
A task is not billable merely because it was necessary. Agree whether discovery calls, revisions, travel, research or meetings are included in the fee, charged separately or excluded. Record those categories consistently.
When a client asks for extra work, clarify the scope and billing basis before adding it to the invoice. Preserve the approval and the underlying task record so the billed hours can be explained without reconstructing the week from memory.
Compare the plan with actual approved time
The 26-hour plan is a capacity assumption. It does not prove that 26 hours will be sold, approved or paid every week. Compare estimated hours with actual approved timesheets and the payments received.
In the separate five-day timesheet exercise, the recorded week has 29 billable hours. That is a worked record for one week, not evidence that the 26-hour annual planning assumption is wrong. Review a meaningful sequence of weeks before changing your plan.
