Free calculators for immigrants and visa holders

Most financial calculators assume you have always lived in the United States. These do not. They are built around the specific arithmetic newcomers actually need: what an offered salary becomes after federal, state, and FICA withholding; what a transfer home really costs once the exchange rate margin is counted; and whether your days in the country have made you a tax resident.

All of them run entirely in your browser. Nothing you type is sent to a server, stored, or attached to an account, and there is no sign-up. They are planning tools built on published rates and formulas, which means they are useful for deciding and budgeting, and not a substitute for tax software or a professional when you file.
