Questions

How do I add VAT to a price?

Multiply the price by the rate and divide by 100 to get the VAT, then add it. At 5%, 100 + 5 = 105. At 20%, 100 + 20 = 120.

How do I remove VAT from a total?

Divide the total by 1 plus the rate as a decimal. At 5%, 105 ÷ 1.05 = 100 before VAT, so the VAT is 5. At 20%, 120 ÷ 1.2 = 100. A common mistake is taking 5% off the total, which gives the wrong answer.

Does it work for GST and sales tax?

Yes. The maths is the same for VAT, GST and sales tax; only the rate changes. Type any rate or tap one of the common ones.

Put the subtotal, the tax with its rate on its own line, and the total. The free invoice generator does it for you, with your tax number.
