How Sales Tax Is Calculated
To add tax to a price, multiply the price by the tax rate and add it to the original amount. To find the pre-tax price from a total that already includes tax, divide the total by (1 + tax rate). This calculator handles both directions.
Sales tax rates vary by country, state, and even city — check your local rate before relying on the result for filing purposes.
Frequently Asked Questions
Can I calculate the pre-tax price from a receipt total?
Yes, switch to 'Remove Tax from Total' and enter the total amount you paid along with the tax rate.
Does this handle multiple tax rates (state + local)?
Combine your rates into one total percentage first (e.g. 6% state + 2% local = 8%) and enter that combined rate.
Is this tool a substitute for professional tax advice?
No, this is a simple arithmetic calculator for everyday use, not tax or legal advice.
