- Add tax: tax = price × rate ÷ 100, and the total is the price plus the tax. 100.00 at 20% → 20.00 tax, 120.00 total.
- Remove tax: price before tax = total ÷ (1 + rate ÷ 100), and the tax is the difference. 119.00 at 19% → 100.00 before tax, 19.00 tax.
For several items, the prices are totalled first and the tax is worked out once, on the total. The page address keeps the amount, rate and mode, so you can share the result. Nothing is sent to us: the maths runs in your browser.
Good to know
Why isn't there a list of rates by country?
Rates change, and many countries have several rates depending on what's sold. A wrong rate filled in for you is worse than none, so the quick picks are just common rates. Check the rate that applies to your goods or services with your tax authority.
How do I use it for US sales tax?
US sales tax is often several rates added together: state, county and city. Enter the combined rate, such as 8.875%. Rates with up to three decimals are accepted.
Why do the net price and the tax always add up to the total?
The amount is rounded only once: the tax when you add it, the price before tax when you remove it. The other figure is the difference, so the three never disagree by a cent.
Does it work in my currency?
Yes. Choose your currency above the calculator. Currencies without cents, such as the Japanese yen, are rounded to whole units.
Is this tax advice?
No. It's a calculator. Which rate applies, and whether tax is due at all, depends on what you sell and where, so check with your tax authority or an accountant.
