How to calculate California sales tax in 3 steps

  1. Enter your amount. Type the price you are working with — either before tax or tax-inclusive, depending on what you have.
  2. Pick the rate and direction. The 7.25% state base rate is pre-filled and editable; choose “Add tax” or “Remove tax”.
  3. Read the split instantly. You get the net amount, the exact tax, and the gross total — ready to quote, invoice, or check a receipt against.

Why getting the California split right matters

Sales tax is the part of the price most people get wrong, because the rate on the shelf is rarely the whole story. Counties and cities often add their own tax on top of the state rate, so the total at the register can be higher than the state figure. This calculator starts from the state base rate — and if you know your combined local rate, type it in and it calculates that instead.
