Unequal hours at different rates
Ten hours at USD 100 and five at USD 160 produce USD 1,000 and USD 800. USD 1,800 ÷ 15 hours is USD 120/hour. The simple rate average of USD 130 would misstate this mix.

Free Blended Hourly Rate Calculator
A project can include design, development and review at different approved rates. Find the effective weighted rate for that exact mix without replacing the client-facing line detail with a misleading simple average.
What you can do here
Calculate a weighted hourly rate from three work groups, retaining each group's hours, rate and rounded subtotal.
Built for real invoice workflows
Keep the approved rate groups on the invoice even when reporting one weighted summary internally.

Calculation notes
How the result is calculated
Round each group's hours × hourly rate to cents. Add those line subtotals, then divide by total hours to obtain the weighted summary rate. The displayed rate rounds to cents and must not be multiplied back to recreate the invoice: use the line subtotals. Hours accept two decimals, not HH:MM; tax, expenses and fixed charges are separate.
Formulas and examples reviewed October 2, 2026. Illustrative figures; no tax or contractual determination.
A display rate cannot replace lines
Two hours at USD 100 and one at USD 101 total USD 301. The weighted rate displays USD 100.33/hour; multiplying that by three yields USD 300.99, so preserve the USD 301 line total.
Questions about this calculation
Is the weighted rate a new agreed client rate?
No. It summarizes the entered mix. A new blended billing arrangement needs its own approval before replacing individual rates.
Can I mix hourly work and a fixed fee?
Keep a fixed fee separate. This tool weights hourly groups only; assigning invented hours to a fixed charge would change the meaning of the summary.
How to use it
1
Enter approved decimal hours and rates for up to three work groups.
2
Use zero hours for an unused group and keep all rates in one currency.
3
Review the line subtotals and weighted summary together.
Why it helps
Weight rates by hours rather than averaging rate labels.
Retain group totals for the invoice evidence.
Make mix changes visible without changing approved rates.
