Billable Hours Calculator
Work out your billable hours, utilization rate, and billable revenue. Enter your total worked hours, the non-billable hours (admin, breaks, internal work), and your hourly rate. The calculator subtracts non-billable time to find your billable hours, shows what fraction of your time is billable, and multiplies by your rate to estimate revenue.
Formula
Billable Hours = Total Worked Hours − Non-billable Hours
- Billable hours = total worked hours − non-billable hours (admin, breaks, internal tasks).
- Utilization = billable hours ÷ total worked hours × 100; it shows how much of your time earns revenue.
- Billable revenue = billable hours × your hourly rate.
- Higher utilization means more of your time is billable, but extremely high values can signal overwork or under-counted admin time.
- Track this regularly to price your time and plan capacity.
180 total hours, 30 non-billable, rate 5,000/hr
Inputs
- Total Worked Hours: 180
- Non-billable Hours: 30
- Billable Rate (per hour): 5000
Billable hours = 180 − 30 = 150. Utilization = 150 / 180 ≈ 83.3%. Revenue = 150 × 5,000 = 750,000.
Frequently asked questions
What are billable hours?
Billable hours are the hours you can charge a client for, found by subtracting non-billable time (admin, breaks, internal work) from your total hours worked.
What is a good utilization rate?
It varies by role, but many consultants and agencies target roughly 70–85%. Some non-billable time is normal and necessary.
How is billable revenue calculated?
Multiply your billable hours by your hourly rate. For 150 billable hours at 5,000 per hour, that's 750,000.
Why track billable hours?
It helps you set rates, measure productivity, plan workload, and understand how efficiently your time converts into income.
