How Sales Tax Is Calculated

Tax = item price × (tax rate ÷ 100) Total price = item price + tax

Sales tax rates vary by state, county and city in the US — typically 0% to 10%+. Some states have no sales tax (Oregon, Montana, New Hampshire, Delaware). Some items (groceries, clothing) may be exempt or taxed at a reduced rate depending on location.

**Use cases**: Budgeting for purchases, comparing prices across states, estimating total cost before checkout.

Tax = price × rate ÷ 100
Total = price + tax
Rates vary by state/city
Some items tax-exempt depending on location

Worked Example

Example: $100 item, 7% sales tax.

- Tax = $100 × 0.07 = $7 - Total = $100 + $7 = $107

Example: $250 item, 8.25% tax. - Tax = $250 × 0.0825 = $20.63 - Total = $270.63
