Freelance Utilization Rate Calculator
Measure your utilization rate — billable hours as a share of available hours — and see the hourly rate you must charge to hit a revenue target at that utilization.
How to use this tool
- Enter your billable hours for the period (week, month, or year).
- Enter your total available working hours for the same period.
- Enter the revenue target you want those billable hours to produce.
- Read your utilization rate, non-billable hours, and the rate you need.
How much of your week do you actually bill? Enter your billable and available hours to get your utilization rate, the non-billable hours it leaves, and the hourly rate you must charge to reach a revenue target at that utilization.
Formula
Utilization rate = Billable hours ÷ Available hours × 100%
Non-billable hours = Available hours − Billable hours
Rate needed for target = Revenue target ÷ Billable hours
Revenue per available hour = Revenue target ÷ Available hours
How it works
Utilization is the freelancer's most underrated metric: the fraction of your available time that you actually bill. If you are available 2,000 hours a year but invoice 1,200, your utilization is 60%, and the other 800 hours — sales, admin, learning, unpaid revisions — must be funded by the rate you charge on the billable ones. The calculator reports utilization, the non-billable hours it implies, and the hourly rate needed to hit a revenue target at that utilization.
Lower utilization is not failure; it is reality. Agencies often target 60–80% for client-facing staff, and solo freelancers frequently sit lower because they also run the whole business. The key insight is the trade-off: the revenue-per-available-hour figure stays the same whether you bill more hours at a lower rate or fewer hours at a higher rate to reach the same target — so raising your rate is usually easier than manufacturing more billable hours from a fixed week.

Worked example
1,200 billable of 2,000 available hours, $90,000 target
- Utilization = 1,200 ÷ 2,000 = 0.60 = 60%.
- Non-billable hours = 2,000 − 1,200 = 800.
- Rate needed = 90,000 ÷ 1,200 = 75.
- Revenue per available hour = 90,000 ÷ 2,000 = 45.
Utilization rate = 60.00%
Rate needed for a $90,000 target by utilization (2,000 available hours)
| Utilization | Billable hours | Rate needed |
|---|---|---|
| 40% | 800 | $112.50 |
| 50% | 1,000 | $90.00 |
| 60% | 1,200 | $75.00 |
| 70% | 1,400 | $64.29 |
| 80% | 1,600 | $56.25 |
| 90% | 1,800 | $50.00 |
Key terms
- Utilization rate
- Billable hours divided by available hours — the share of your time that earns revenue.
- Available hours
- The total hours you are realistically available to work in the period.
- Non-billable hours
- Hours spent on sales, admin, learning and other work you cannot invoice.
- Revenue per available hour
- Target revenue spread across all available hours, a blended yield on your time.
Frequently asked questions
- What is a good utilization rate for a freelancer?
- There is no universal target, but 60–80% is common for client-facing work. Solo freelancers often run lower because they also handle sales, admin and operations. Lower utilization simply means you need a higher hourly rate.
- Why does my rate go up when utilization falls?
- Because the same revenue target must be earned over fewer billable hours. If half your available time is non-billable, each billable hour has to carry twice the load.
- Should I count vacation in available hours?
- Use the hours you are genuinely available to work. Excluding planned time off gives a cleaner utilization figure; just keep both the billable and available numbers on the same basis.
