Sales Tax Calculator — Exact Tax and Total
Sales tax rates vary by state, county, and city, so a quick, accurate calculation matters whether you are a shopper checking a receipt or a seller pricing an item. Enter your net amount and tax rate to get the tax and the gross total instantly.
How It Works
The tax is simply Net × (rate ÷ 100), and the gross is Net + Tax. For a $100 item at an 8.25% rate, the tax is $8.25 and the total is $108.25. Reverse the process to find a pre-tax price from a tax-inclusive total.
Why Rates Differ
US sales tax is set at multiple levels and combined into one rate at checkout, which is why your effective rate may be 8.25% rather than a round state figure. Always use the combined rate for your exact location.

Sales Tax Calculator — Frequently Asked Questions
Got questions about Sales Tax Calculator? Here are clear, honest answers to the most common questions about pricing, privacy, compatibility, and features.
How do I calculate sales tax on a price?
Multiply the net price by the tax rate expressed as a decimal. For 8.25%, multiply by 0.0825, then add the result to the net price for the total.
How do I find the pre-tax price from a total?
Divide the tax-inclusive total by (1 + rate). For an 8.25% rate, divide the total by 1.0825 to recover the original pre-tax price.
What sales tax rate should I use?
Use the combined state, county, and city rate for the buyer's location, since US sales tax is layered across jurisdictions and charged as a single combined rate.
Is sales tax the same as VAT or GST?
They are similar consumption taxes but applied differently. Sales tax is charged once at the final sale, while VAT and GST are collected at each stage of the supply chain.
