Frequently asked questions
Is this tax or accounting advice?
No. It is a transparent planning estimate based only on the values entered.
Should I compare multiple scenarios?
Yes. Test conservative and optimistic billable capacity, expenses and margin assumptions before setting a rate or price.
When should I recalculate with the Profit per Project Calculator?
Recalculate whenever your capacity, expenses, target income, margin, reserve or project scope changes.
Why should I use realistic assumptions in the Profit Per Project?
Using total working time as billable time usually understates the rate or price required because administration, sales, leave and downtime are not invoiced.
