FAQ

How do I calculate sales tax?

Multiply the item price by the sales tax rate as a decimal. For example, if the price is $100 and the tax rate is 8.25%, the tax is $8.25.

How do I remove sales tax from a total price?

Divide the total by 1 plus the tax rate as a decimal. This gives you the original pre-tax price. The difference is the included tax amount.

What is the formula for sales tax?

Sales Tax = Price × (Tax Rate ÷ 100). Total Price = Price + Sales Tax.

Is sales tax the same in every U.S. state?

No. Sales tax can vary by state, county, and city, so the final rate depends on the location of the purchase.

Can I use this calculator for online shopping and receipts?

Yes. It is useful for online orders, store receipts, invoices, pricing estimates, and business calculations.
