How is sales tax calculated?

Multiply the purchase price by the sales tax rate. On a $100 item at 8.25%, the tax is $8.25 for a $108.25 total.

Why do sales tax rates vary?

Sales tax is set by state and local governments, so the combined rate differs by city and state — and some states have no sales tax at all.
