How to Read Your Results
Gross profit shows revenue after direct delivery costs only; it is not the same as net profit.
Total monthly costs include all four cost inputs and are deducted when calculating net profit.
A positive net profit means entered revenue exceeds entered costs for the month.
A negative net profit margin means the project costs more to deliver and support than it earns in that period.
Compare similar engagements using the same period and the same overhead allocation method.
Assumptions & Important Notes
- Each example treats all figures as amounts for one month in the same currency.
- Staff and overhead figures are allocations attributable to the specific engagement.
- The examples exclude taxes, financing costs, owner drawings and costs not entered.
- The figures illustrate calculation mechanics and are not benchmarks for accounting firms or engagements.

Frequently Asked Questions
Why can an engagement have a high gross margin but a low net margin?
Gross margin deducts only direct costs. Net margin also deducts staff costs, allocated overheads and other expenses.
What does a negative net margin mean in an example?
It means total entered costs are higher than the project's monthly revenue for that calculation period.
Can I use these examples with another currency?
Yes. The calculation uses consistent monetary amounts, so the same method works in any currency.
Why should recurring and one-off work be reviewed separately?
Their revenue patterns, staff time, direct costs and overhead use can differ, making a combined monthly margin less informative.
