Profit is what remains after your time cost, expenses, contingency and payment fee. It is not your after-tax take-home income.

If the work takes longer…

Same price. Five extra hours.

Assume five additional hours on top of the budgeted contingency. See how your margin changes.

First we calculate your time cost, add direct costs and overhead, then include the contingency allowance. We then find a price that covers the payment fee and leaves your chosen margin. A 30% margin is not the same as adding 30% to costs.

Cost = (hours × hourly cost + direct costs + overhead) × (1 + contingency/100)
Price = (cost + fixed fee) ÷ (1 − fee/100 − margin/100)

Assumes one currency and one payment, with a payment fee on the pre-tax price. Amounts are shown to two decimals; the price is rounded up. Example fees are illustrative, not the rates of Lemon Squeezy or any other provider. Taxes, electronic invoicing and local tax rules are not calculated.
