About
ChargeWhat is a free, no-signup calculator for US and UK freelancers to find their minimum hourly rate. It works backwards from your target take-home pay, accounting for self-employment tax (15.3% on 92.35% of net profit), all 50 US state income tax rates, UK Income Tax and Class 4 NI, health insurance, business expenses, and a profit buffer. No guessing — just the rate you actually need to charge.
