Sales Tax Calculator
Calculate the tax amount and final price for any purchase using a tax rate you enter.
How this calculator works
- Enter the pre-tax price.
- Enter your local sales tax rate as a percentage.
- The calculator multiplies the price by the rate to find the tax amount, then adds it to the price for your final total.
Sales tax rates vary by country, state, county and even city, and change over time — so this calculator asks you to enter your local rate directly rather than guessing at it. Check a recent receipt or your local government's website for the current rate in your area.
Example
A $50 item with an 8.25% tax rate: tax = $50 × 0.0825 = $4.13. Final price = $50 + $4.13 = $54.13.
Limitations
We don't embed current tax rates by state or country since they change frequently and vary by product category in many places. Always use the rate shown on your receipt or your local tax authority's published rate for anything important.
Frequently asked questions
How do I calculate sales tax?
Multiply the price by the tax rate (as a decimal). Add that amount to the original price for your total.
What is my local sales tax rate?
This varies by country, state, county and city, and sometimes by product type. Check a recent receipt or your local government's official site for the exact current rate.
Can I calculate the pre-tax price from a total?
Divide your total by (1 + tax rate as a decimal). For example, $54.13 at 8.25% tax means the pre-tax price was $54.13 ÷ 1.0825 ≈ $50.
Does this work for VAT or GST?
Yes — enter your VAT/GST rate the same way; the math for adding a percentage-based tax is the same.
