Most freelancers don't have a pricing problem — they have a math problem.
The classic mistake: take your old salary, divide by 2,080 working hours, and charge that. It feels scientific, and it quietly bankrupts you, because a freelancer's billable hours are roughly half of a salaried employee's paid hours — and you're also paying the taxes, insurance, equipment, and software an employer used to cover. Every tool here exists to correct one piece of that math:
- The hourly rate calculator grosses up your income for taxes and expenses, and discounts your hours for all the non-billable work you actually do.
- The project rate calculator prices the risk of fixed-scope work instead of hoping the estimate holds.
- The invoice generator produces invoices with the details accounts-payable departments need to actually pay you.
- The break-even calculator tells you how many clients the business really needs each month.
- The late fee calculator turns an awkward chase email into a precise one.
Everything runs locally in your browser. No accounts, no tracking your financial data, no "enter your email to see the result." Start with the rate calculator — it's the number everything else depends on.
