About PayPilot

PayPilot is built for US workers who want a clear, fast way to explore salary, paycheck and compensation questions. The tools are free to use and do not require an account.

How our calculators work

Core calculations run locally in your browser. We separate tax-year data from calculator screens so the federal and state modules can be reviewed and updated without rebuilding the site.

Privacy approach

Normal calculator inputs are not sent to a PayPilot server. We do not ask for login details or payment information to use a calculator.

Tax rule review

Federal and payroll values are documented on the Tax Data & Sources page. State rules are added only after a reviewable annual module is available; this avoids implying false precision.
