How do I calculate sales tax?

To calculate sales tax, multiply the price by the tax rate as a decimal. For example, for an $100 item with 8.5% tax: $100 × 0.085 = $8.50 tax. Total price: $100 + $8.50 = $108.50.

How do I remove sales tax from a total?

To remove sales tax, divide the total by (1 + tax rate as decimal). For example, if the total is $108.50 with 8.5% tax: $108.50 / 1.085 = $100 original price.

What is the sales tax rate in my state?

Sales tax rates vary by state and locality, ranging from 0% (no sales tax states like Oregon) to over 10% in some cities. Check your local government website for exact rates, as city and county taxes may apply on top of state tax.
