Finance Calculators

Paychecks, dividends and more — money questions answered fast.

ziffaro’s finance calculators answer the money questions that come up most — paychecks, taxes, mortgages, loans, savings and more — clearly, with every number broken down so you can follow each step. Estimate your take-home pay after federal, state and FICA taxes; work out a monthly mortgage or car payment; project compound interest or a 401(k); or figure sales tax, capital gains and self-employment tax. Many tools adapt to your state, since US taxes and rates vary widely by location. Everything runs in your browser, updates instantly as you type, and is free with no signup. Results are estimates for general information, not financial advice — for big decisions, confirm the figures with the official source or a qualified professional.
