Result
Enter an amount and a tax rate.
How to use it
- Enter the amount.
- Type the tax rate, or tap a country's standard rate (each shows where we checked it).
- Choose whether the amount is before tax (add tax) or already includes tax (remove tax).
The formula
- Add tax: tax = amount × rate ÷ 100; total = amount + tax
- Remove tax: amount before tax = total ÷ (1 + rate ÷ 100); tax = total − amount before tax
Questions
How do I take VAT out of a price that already includes it?
Divide the price by 1 plus the rate. At 20%, a price of 120 is 120 ÷ 1.20 = 100 before VAT, so the VAT is 20. Do not take 20% of 120 — that gives 24, which is wrong.
Are the country rates always right for my items?
They are the standard rates, read from each tax authority on the date shown. Many items have a reduced, zero or exempt rate, and some services are taxed by a province or emirate at a different rate. Check with your tax adviser for your items.
Does this work for GST?
Yes. GST, VAT and sales tax are calculated the same way here — type your rate and choose add or remove.
Is my data saved?
No. The calculator runs in your browser and nothing you type is sent or stored.
