How to use it
- Enter the pre‑tax price.
- Enter the sales‑tax rate as a percent.
- Click Calculate to see the tax amount and total price.
The Sales Tax Calculator lets you input a price before tax and the applicable tax rate, then instantly shows two numbers: the sales tax you’ll owe and the final amount you’ll pay. Knowing the exact tax amount helps you budget accurately, compare prices across jurisdictions, and avoid surprises at checkout. The Sales tax line is the monetary value added based on the rate you entered. The Total with tax line adds that amount to your original price, giving you the amount you’ll actually hand over. No hidden steps—just type, click, and read. Use it for everyday purchases, business invoices, or travel expenses to stay in control of your spending.
Pro tips
- Round the tax amount to the nearest cent for cash transactions.
- If the tax rate includes a decimal, enter it exactly (e.g., 8.25%).
- Use the calculator before ordering to compare vendors with different tax rates.
- Double‑check that you’re using the correct local rate; many states have city‑specific additions.
