Frequently Asked Questions
How do I add sales tax to a price?+
Multiply the pre-tax price by the tax rate to get the tax amount, then add it to the price. For example, $100 at 8% tax is $100 × 0.08 = $8 tax, for a $108 total. This tool does that automatically.
What sales tax rate should I use?+
Rates vary by country, state, county, and city, and some items are exempt or taxed at special rates. Check the rate that applies to your location and purchase — this tool uses whatever rate you enter.
Is anything I enter stored?+
No. The calculation happens entirely in your browser. The prices and rates you enter are never sent to a server.
