About WorkCalc

WorkCalc is a free calculator hub focused on the numbers that come up constantly at work and in personal finance: payroll, salary, taxes, retirement, loans, mortgages, and day-to-day productivity math.

Every calculator shows its formula and a worked example, not just a result. The goal is for the number to be something you can verify, not a black box.

WorkCalc is built for a US audience and free to use, with no account required. Calculations run in your browser; your inputs aren't sent to a server to compute a result.
