Accountants Project Cost (Hourly) Calculator
Estimate an hourly-based accounting project quote using billable time, hourly rate, expenses, overhead and target profit margin.
Overview
Use this hourly project cost calculator to build an estimated accounting project fee from planned billable hours, your hourly rate, direct expenses, an overhead allowance and a target profit margin. It can help you price fixed-fee work while keeping the underlying time and cost assumptions visible.
How it works
The calculator first multiplies estimated hours by the hourly rate to find the labour cost. It then adds direct expenses and an overhead allowance calculated from labour cost. Finally, it divides total project cost by one minus the target profit margin to estimate the fee required to reach that margin. For example, a 20% margin means costs represent 80% of the final fee.
How to use this calculator
- 1Estimate the total billable hours needed for the project.
- 2Enter the hourly rate you want to recover for that time.
- 3Add any direct expenses that are specific to the engagement.
- 4Choose an overhead allowance for general business costs.
- 5Set the profit margin you want the quoted fee to achieve.
- 6Review the suggested fee and adjust the assumptions for the project scope.

At 25 hours and 120 per hour, labour is 3,000. With 200 of direct expenses and 10% overhead, estimated total cost is 3,500. A 20% target margin gives a suggested project fee of 4,375 and estimated profit of 875.
Frequently asked questions
How do I calculate an hourly project fee for accounting work?
Estimate the hours required, multiply them by your hourly rate, add direct expenses and overhead, then allow for your intended profit margin. This calculator applies those steps automatically.
What is the difference between markup and profit margin?
Profit margin is profit as a percentage of the final selling price. Markup is profit as a percentage of cost. This calculator uses profit margin, so the required fee is calculated from the final quoted price.
Should I include non-billable time in estimated hours?
Include project-specific non-billable tasks if they are needed to deliver the engagement, such as planning, client communication, review and administration. Alternatively, account for them through your overhead allowance.
What counts as a direct project expense?
Direct expenses are costs that arise because of a particular engagement, such as filing fees, specialist software charges, travel, outsourced work or document retrieval costs.
Why should I add an overhead allowance?
An overhead allowance helps recover general operating costs that are not tied to one project, such as office costs, subscriptions, insurance, administration and management time.
Can I use this calculator for fixed-fee accounting services?
Yes. It is particularly useful for estimating a fixed fee from an expected time budget and cost base. Update the hour estimate and cost assumptions when the scope changes.
