What Is Sales Tax?
Sales tax is a consumption tax imposed by governments on the sale of goods and services. It is typically calculated as a percentage of the purchase price and collected by the seller at the time of sale.
For example, if a product costs $100 and the sales tax rate is 8%, the sales tax amount would be $8, making the final price $108.
How to Calculate Sales Tax
To calculate sales tax, use the following formula:
Sales Tax = Original Price × (Tax Rate ÷ 100)
Final Price = Original Price + Sales Tax
Example
- Product Price: $250
- Tax Rate: 7.5%
Sales Tax = $250 × 7.5% = $18.75
Final Price = $250 + $18.75 = $268.75
Reverse Sales Tax Formula
Sometimes you know the final amount paid but want to find the original price before tax.
Original Price = Total Price ÷ (1 + Tax Rate ÷ 100)
Example
- Total Price: $535
- Tax Rate: 7%
Original Price = $535 ÷ 1.07 = $500
Sales Tax = $535 − $500 = $35
