What Is This Calculator?
A sales tax calculator determines the total cost of a purchase after applying the local sales tax rate. Sales tax rates vary by state and locality in the US, ranging from 0% (Oregon, Montana) to over 10% in some areas.
How to Calculate
To calculate sales tax: 1) Enter the purchase price before tax. 2) Enter the applicable sales tax rate. 3) The calculator multiplies price by (1 + rate/100). Formula: Total = Price × (1 + Tax Rate / 100).
Examples
Example: A $99.99 item at 8.25% sales tax. Tax = $99.99 × 0.0825 = $8.25. Total = $99.99 + $8.25 = $108.24.
