About Sales Tax
Sales tax is a consumption tax imposed by governments on the sale of goods and services. It's typically calculated as a percentage of the purchase price and added to the total amount due.
How to Calculate Sales Tax
- Step 1: Identify the pre-tax price of the item
- Step 2: Find the sales tax rate for your location
- Step 3: Multiply the price by the tax rate (as a decimal)
- Step 4: Add the tax amount to the original price
Formula
Tax Amount = Price × (Tax Rate ÷ 100)
Total Price = Price + Tax Amount
Total Price = Price + Tax Amount
