How to Read Your Results
Recommended project fee is the estimated fee needed to cover the listed costs and achieve the selected profit margin.
Estimated total cost is the labour value plus direct expenses and the overhead allowance, before profit.
Estimated profit is the difference between the suggested fee and estimated total cost.
If the scope changes, revise estimated hours, direct expenses and any relevant overhead assumption before relying on the result.
Assumptions & Important Notes
- All amounts use the same currency.
- The hourly rate and estimated hours represent the expected delivery effort.
- Overhead is applied to labour cost only.
- Profit margin is calculated from the final quoted fee rather than from cost.

Frequently Asked Questions
Can I use these examples for fixed-fee accounting work?
Yes. They illustrate how a fixed fee can be estimated from an underlying hourly cost model.
Why is the quote higher than labour cost?
The calculation may include direct expenses, overhead and an amount for the selected profit margin.
What happens if direct expenses are zero?
Total project cost is then made up of labour and overhead only.
Should I round the recommended fee?
You can round the result for quoting purposes, while checking that the rounded figure still meets your intended cost and margin assumptions.
