I built a free freelance rate calculator because I kept seeing people undercharge

Hello everyone!

I think the math most freelancers use is wrong. They take a salary number, divide by 2,080, and call it their rate. That ignores many key factors, such as self-employment tax (15.3%), state income tax, unpaid hours, health insurance, and expenses.

I decided to build ChargeWhat. You start off by putting in what you need to take home each year. It tells you what you actually need to charge to get there. All 50 US states. Full UK support too. Free, no signup: chargewhat.app

I would love to hear what you think and how I can improve it!
