Consulting Bill Rate Calculator
Work out the hourly rate to charge a client so that target margin is met after overhead and non-billable time.
What this calculator does
A fully loaded cost per billable hour is divided by one minus the target margin to give the rate that produces that margin. Every cost element is entered by the organisation. The calculator performs no lookup of market rates and applies no default salary, overhead or margin.
Inputs and what they mean
- Currency
- — Amounts are shown in the currency you pick. No exchange rate is applied..
- Annual salary
- — number value.
- Annual benefits and payroll cost
- — number value.
- Annual overhead allocated
- — number value.
- Annual available hours
- — number value.
- Utilisation
- — Share of available hours that is billable..

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
Cost per billable hour = (Annual salary + Annual benefits + Annual overhead) ÷ (Annual available hours × Utilisation); Bill rate = Cost per billable hour ÷ (1 − Target margin)
Worked example
Consultant on $120,000 with 70% utilisation
Salary, benefits and allocated overhead at a 35% target margin.
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
Results depend entirely on the figures you enter and are rounded for display. They are for general information and education, not professional advice.

Common questions
Formula, source and verification
A fully loaded cost per billable hour is divided by one minus the target margin to give the rate that produces that margin.
The question it answers: How much should I charge a client per hour so the work still makes the margin we need?
The formula
Cost per billable hour = (Annual salary + Annual benefits + Annual overhead) ÷ (Annual available hours × Utilisation); Bill rate = Cost per billable hour ÷ (1 − Target margin)
- S — Annual salary
- (currency). Base pay for the person being billed.
- B — Annual benefits and payroll cost
- (currency). Employer-paid benefits, taxes and insurance.
- O — Annual overhead allocated
- (currency). Share of firm overhead allocated to this person.
- H — Annual available hours
- (h). Working hours available before utilisation.
- U — Utilisation
- (%). Share of available hours that is billable.
- m — Target margin
- (%). Margin wanted on the billed rate.
Units: Currency per hour; hours; percentages.
What kind of calculation this is
Business input model. The answer depends on business figures only you can supply, such as your own costs, rates or volumes. No market or benchmark values are assumed for you.
Method
Every cost element is entered by the organisation. The calculator performs no lookup of market rates and applies no default salary, overhead or margin.
Assumptions built into the result
- Mathematical: All figures cover the same twelve-month period.
- Business: Utilisation and margin are entered as percentages of the stated bases.
Figures this calculator will never guess for you
- No market or industry-average bill rate is inserted.
- No default utilisation, overhead or margin is assumed.
Limitations
- Produces the rate implied by the inputs; it does not say what a client will accept or what competitors charge.
