Sales Tax Calculator
Calculate sales tax on purchases
About the Sales Tax Calculator
Sales tax turns a tidy shelf price into an awkward total at the register, and rates differ from one place to the next. This calculator takes a pre-tax price, a quantity, and a tax rate, and tells you the tax per item and the full amount due — so there are no surprises at checkout.
Shoppers use it to budget before buying; small sellers and freelancers use it to add the correct tax to an invoice or quote. Because it multiplies by quantity, it is equally happy with a single purchase or a bulk order where the per-item tax needs to scale up.
How to Use the Sales Tax Calculator
- Enter the price of one item before tax.
- Enter the quantity you are buying.
- Enter your local sales tax rate as a percentage.
- Read the tax per item, the single-item total, and the grand total across all units, then Copy if needed.

- It calculates instantly client-side with no sign-up, ready whenever you need a quick total.
Frequently Asked Questions
How do I calculate sales tax on a purchase?
Multiply the price by the tax rate as a decimal: a 7% tax on a $50 item is 50 × 0.07 = $3.50, for a total of $53.50. Enter the price, quantity, and rate here and the calculator handles per-item and total amounts for you.
What sales tax rate should I enter?
Use the combined rate for your location, which may stack state, county, and city taxes. Rates vary widely by jurisdiction, so check the rate that applies where the purchase happens and enter that single combined percentage.
Is sales tax the same as VAT?
They are similar consumption taxes but work differently — sales tax is added once at the final sale, while VAT is collected at each stage of production. If you need to add or strip VAT from a price, use the dedicated VAT calculator instead.
Are some items exempt from sales tax?
Often, yes. Many jurisdictions exempt or reduce tax on essentials like groceries, prescription medicine, or clothing, and rules vary by location. If an item is exempt, simply leave it out or enter a 0% rate for it; this calculator applies whatever rate you specify.
