How this calculator works
Proposal price = ((hours × rate + expenses) × (1 + contingency)) ÷ (1 − margin).
Worked example
80 hours at $125 plus $1,500 expenses, 10% contingency and 20% margin produces about $15,812.50.
How to interpret the result

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 Proposal Pricing Calculator?
Recalculate whenever your capacity, expenses, target income, margin, reserve or project scope changes.
Why should I use realistic assumptions in the Proposal Pricing?
Using total working time as billable time usually understates the rate or price required because administration, sales, leave and downtime are not invoiced.
