How to Calculate Sales Tax
Sales tax is a consumption tax imposed by governments on the sale of goods and services. In the United States, sales tax varies by state, county, and city. Unlike VAT systems used in Europe, US sales tax is only collected at the final point of sale. This calculator helps you quickly determine the total cost of a purchase including tax.
The Formula
Tax Amount = Price × (Tax Rate / 100)
Total Price = Price + Tax Amount
Or simply: Total = Price × (1 + Tax Rate / 100)
Reverse Tax Calculation
To find the pre-tax price when you know the total: Pre-tax Price = Total / (1 + Rate/100). If you paid $108.25 with a 8.25% tax rate: $108.25 / 1.0825 = $100.00 pre-tax.
US Sales Tax Rates by State (2024-2025)

Local taxes can significantly increase the total rate. Louisiana has the highest combined rate at over 9.5% on average. The national average combined rate is approximately 6.6%.
Sales Tax vs. VAT
Sales tax is collected once at the point of sale to the end consumer. VAT (Value Added Tax), used in most of the world, is collected incrementally at each stage of production. Both aim to tax consumption, but VAT is generally considered more efficient at preventing tax evasion.
