VAT Calculator
Value added tax is charged on the price of goods and services and is normally included in the price you see. Adding it is a multiplication; removing it is a division, and mixing the two up is the most common VAT error.
Gross price
$240.00
- Net price
- $200.00
- VAT amount
- $40.00
Values update as you type. This calculator covers the single scenario its formula assumes — see Common Mistakes for what it leaves out.
The formula this calculator uses
Gross = net x (1 + rate)
- net
- Price before VAT
- rate
- VAT rate as a decimal, such as 0.20 for 20%
- gross
- Price including VAT
- vat
- The tax portion, gross minus net
How to check the result by hand
- 1
Identify the figure you have
If the price excludes VAT you are adding it; if it already includes VAT you are removing it. The two use different operations.
- 2
Convert the rate to a decimal
20% becomes 0.20 and 5% becomes 0.05.
- 3
Form the multiplier
Add one to the rate. The multiplier is 1.20 for 20% VAT and 1.05 for 5%.
- 4
Multiply or divide
Multiply a net price by the multiplier to get the gross, or divide a gross price to recover the net.
- 5
Find the VAT amount
Subtract the net from the gross. For 240 gross at 20% that is 240 minus 200, or 40 of VAT.
