Accountants Break-Even Rate Formula
Learn how to calculate the hourly billing rate an accounting practice needs to cover costs and achieve a target profit margin.
This calculation converts annual compensation, overhead, employment costs, billable hours and a profit target into an estimated hourly charge-out rate. It helps show whether an hourly fee can recover the practice cost base while leaving the intended operating profit.

Required Hourly Billing Rate
Where:
First calculate all annual operating costs. Increase that amount so costs represent the chosen share of revenue after profit, then divide the revenue target by realistic annual billable hours.
Variables Explained
| Variable | What It Means | Unit |
|---|---|---|
| annualCompensation - Desired annual compensation | Annual pay the practice is intended to provide before employment-related costs. | currency |
| annualOverhead - Annual business overhead | Recurring annual practice costs such as software, insurance, rent, marketing and professional fees. | currency |
| employmentCostRate - Employment costs and benefits | Compensation-related costs expressed as a percentage of compensation. | percent |
| targetProfitMargin - Target profit margin | Target operating profit as a percentage of revenue after listed costs. | percent |
| annualBillableHours - Annual billable hours | Hours expected to be invoiced during the year. | hours |
Step-by-Step Calculation
Calculate employment costs
Apply the employment cost percentage to the desired annual compensation.
employmentCosts = annualCompensation * (employmentCostRate / 100)
Calculate annual operating cost
Add compensation, related employment costs and annual overhead.
annualOperatingCost = annualCompensation + annualOverhead + employmentCosts
Find the cost recovery rate
Divide annual operating cost by billable hours to find the rate that covers costs before profit.
costRecoveryHourlyRate = annualOperatingCost / annualBillableHours
Calculate required annual revenue
Gross up operating costs so the remaining share of revenue equals the target profit margin.
requiredAnnualRevenue = annualOperatingCost / (1 - targetProfitMargin / 100)
Calculate the required hourly billing rate
Divide the annual revenue target by expected billable hours.
breakEvenHourlyRate = requiredAnnualRevenue / annualBillableHours
Example: small accounting practice hourly rate
Employment costs
$80,000 × 20%
$16,000
Annual operating cost
$80,000 + $30,000 + $16,000
$126,000
Cost recovery hourly rate
$126,000 ÷ 1,200
$105.00 per hour
Required annual revenue
$126,000 ÷ (1 − 15%)
$148,235.29
Required hourly billing rate
$148,235.29 ÷ 1,200
$123.53 per hour
Final Result
The estimated required hourly billing rate is $123.53 per hour.
Assumptions
- ✓All entered annual costs apply during the year being planned.
- ✓Billable hours are hours that can be invoiced; non-billable work is excluded.
- ✓The target margin is operating profit divided by revenue.
- ✓The calculation assumes invoices are collected in full and on time.
Limitations
- !The estimate does not automatically include sales taxes, bad debts, write-offs, financing costs or capital spending.
- !Actual results can differ because of discounts, scope changes, client mix and utilisation changes.
- !A single blended rate may not suit services with materially different delivery costs or value.
- !This is a planning estimate, not financial, tax or professional advice.
Common Mistakes to Avoid
Using total working hours rather than realistic invoiceable hours.
Leaving owner compensation out of the cost base.
Treating a profit margin as a markup on costs; the calculation uses profit as a share of revenue.
Forgetting recurring costs such as software, insurance, subscriptions and professional memberships.
Using an overly optimistic collection or utilisation assumption.

Frequently Asked Questions
What is the break-even hourly rate formula for an accountant?
Add annual compensation, overhead and employment costs, adjust the total for the target profit margin, then divide by annual billable hours.
How is the cost recovery rate different from the required hourly rate?
The cost recovery rate covers listed costs only. The required hourly rate also includes revenue for the selected profit margin.
Why is the formula divided by one minus the profit margin?
If profit is 15% of revenue, costs must equal 85% of revenue. Dividing costs by 0.85 finds the revenue needed.
Can the target profit margin be 100%?
No. At 100%, the cost share of revenue is zero, so a finite revenue target cannot be calculated.
