How to Calculate Sales Tax
Sales tax is a percentage added to the price of a product or service. The final amount you pay depends on the original price and the sales tax rate in your state or local area.
The basic formula is:
Sales Tax = Item Price × Sales Tax Rate
For example, if an item costs $100 and the sales tax rate is 8%, the sales tax is $8. The final price would be $108.
Example
If you buy an item for $250 and the sales tax rate is 7.5%, the sales tax amount is $18.75. The final total would be $268.75.
Why Sales Tax Rates Vary
Sales tax rates can vary depending on the state, county, city, and type of purchase. Some states have no statewide sales tax, while others may have different local tax rates.
