Effective Bill Rate Calculator
Revenue per hour worked, not just per hour billed.
In short
Revenue per hour worked, not just per hour billed.
Formula: Effective rate = Revenue billed ÷ Total hours worked; Rate per billable hour = Revenue billed ÷ Billable hours
What this calculator does
Two divisions of the figures entered, shown side by side so the gap between headline and effective rate is explicit.
Use it to turn Currency, Revenue billed, Total hours worked, Of which billable into a checked result you can compare, copy, or rerun with different assumptions.
The page shows the formula, a numeric worked example, and the assumptions that affect this professional & industry calculation.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Revenue billed
- — number value.
- Total hours worked
- — number value.
- Of which billable
- — number value.
How to use it
- Enter your own figures — the calculator never fills in a rate, price or benchmark for you.
- Press Calculate to see the result.
- Read the formula, variables, assumptions and source below the result before you rely on it.
Formula
Effective rate = Revenue billed ÷ Total hours worked; Rate per billable hour = Revenue billed ÷ Billable hours.
Inputs used: Currency, Revenue billed, Total hours worked, Of which billable.
Edge handling: Revenue billed is required.; Revenue billed cannot be negative.; Revenue billed must be no more than 1000000000000.; Total hours worked is required.; Total hours worked cannot be negative..
Worked example
$180,000 billed over 1,800 hours worked
- Start with Currency: USD, Revenue billed: 180000, Total hours worked: 1800, Of which billable: 1400.
- Apply the method: Effective rate = Revenue billed ÷ Total hours worked; Rate per billable hour = Revenue billed ÷ Billable hours.
- Separates the headline rate from the rate earned per hour worked.
Reading the result
The headline figure is the main answer. Any breakdown underneath shows the parts that make it up, so you can check the working and see what changes when you adjust an input.
Limitations and assumptions
- Inputs outside the supported range are rejected rather than forced into a result.
- The result depends on the values you enter for this effective bill rate calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.

Common questions
Where does this formula come from?
Institute of Management Accountants, Statements on Management Accounting — measuring the cost of capacity (resource use versus revenue). See the source link on this page.
What kind of calculation is this?
