Sales Tax Calculator
Free sales tax calculator for U.S. purchases. Enter a price and local tax rate to calculate the tax amount and total cost.
Sales tax can make the price at checkout different from the sticker price. Use this calculator to estimate the tax amount and final total for a purchase.
Enter the pre-tax price and the combined state and local sales-tax rate. Rates vary by location and product, so confirm the applicable rate for your address when accuracy matters.
Frequently asked questions
Does this calculator know my local tax rate?
No. Enter the combined rate that applies to your purchase. State, county, city, and special-district rates may all affect the final rate.
Are all products taxed at the same rate?
Not always. Groceries, clothing, medicine, digital goods, and services may be taxed differently or exempt depending on the state and locality.
Can I use this for reverse sales tax?
This version calculates tax from a pre-tax price. To estimate the pre-tax amount from a tax-inclusive total, divide the total by 1 plus the rate written as a decimal.
