What is Sales Tax?

Sales tax is a consumption tax imposed by the government on the sale of goods and services. It is typically calculated as a percentage of the purchase price and is collected by the retailer at the point of sale. The collected tax is then remitted to the appropriate government authority.

In the United States, sales tax is primarily administered at the state and local levels, which means rates can vary significantly depending on where you make a purchase. Some states have no sales tax at all, while others have combined state and local rates exceeding 10%.

How to Calculate Sales Tax

Calculating sales tax is straightforward:

Tax Amount = Price × (Tax Rate ÷ 100)

Total Price = Price + Tax Amount

Example:

  • Item price: $100
  • Sales tax rate: 7%
  • Tax amount: $100 × 0.07 = $7.00
  • Total price: $100 + $7 = $107.00

FAQ - Sales Tax Calculator

To calculate sales tax, multiply the item price by the sales tax rate (as a decimal). For example, for a $100 item with 7% tax: $100 × 0.07 = $7.00 tax. Add this to the price: $100 + $7 = $107 total. Our calculator does this automatically for you.
