How to Read Your Results
Monthly project cost is the estimated internal cost of delivering the engagement, not the amount charged to the client.
The recommended monthly fee is the pre-sales-tax fee that mathematically supports the selected target margin.
Expected monthly profit is the difference between the calculated fee and the entered delivery costs.
Effective hourly fee is useful for comparing fixed-fee work with an hourly benchmark, but it is not a substitute for reviewing scope.
If actual hours regularly exceed planned hours, the actual margin will generally be lower than the estimate.
Assumptions & Important Notes
- All figures in each example use the same currency and exclude VAT, GST, and similar sales taxes.
- Hourly staff cost is treated as a fully loaded average cost.
- Costs are assumed to recur every month at the amounts shown.
- The selected profit margin is calculated as a share of fee revenue before taxes.

Frequently Asked Questions
Can I use these examples to price an annual accounting engagement?
Yes, as a monthly planning view. Multiply recurring monthly figures by 12 only after checking whether workload, software costs, and hours are consistent throughout the year.
Why is the recommended fee higher than project cost?
The difference is the estimated profit needed to achieve the target margin after costs are covered.
What if my project has seasonal peak months?
Consider modelling peak and normal months separately, or use a monthly hour estimate that reflects the annual average workload.
Should I use one hourly staff cost for every role?
A blended cost can be practical for planning. Where role mix varies significantly, a separate estimate by role may provide more detail.
Can a fixed monthly fee be lower than the calculated fee?
It can, but the resulting estimated margin will be lower unless costs or planned hours also fall.
