Calculating Sales Tax on Purchases
Sales tax varies by state and locality — from 0% in states like Oregon and Montana to over 10% in some cities. CalcSolver's sales tax calculator instantly computes the total cost of any purchase including local tax rates.
A $1,000 purchase in Los Angeles (9.5% sales tax) costs $1,095 total. The same purchase in Chicago (10.25%) costs $1,102.50. For large purchases like furniture or electronics, the tax difference between locations can amount to hundreds of dollars.
Some states exempt certain categories from sales tax — groceries in many states, prescription medications everywhere, and clothing in states like Minnesota and New Jersey. Online purchases are now subject to sales tax in most states regardless of where the seller is located. Use our discount calculator to compute final prices after both discounts and taxes.

Frequently Asked Questions
How do I calculate sales tax?
Multiply the price by the tax rate and divide by 100. For a $50 item with 8% tax: $50 × 0.08 = $4 tax → total = $54.
How do I find the pre-tax price?
If you know the total and tax rate: Pre-tax price = Total ÷ (1 + Tax Rate/100). Example: $54 total with 8% tax → $54 ÷ 1.08 = $50.
Do all states have sales tax?
No. As of 2026, five states have no state sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. Rates in other states range from about 4% to over 10% with local taxes.
