Multiply the net amount by the VAT rate to get the VAT, then add it to the net amount for the gross total.

How do I remove VAT from a gross price?

Divide the gross amount by one plus the rate as a decimal. The result is the net amount, and the difference is the VAT.

Add VAT applies the rate to a net amount to get the gross total. Remove VAT works backwards from a gross amount to find the net amount and the VAT it contains.

Add and remove VAT formulas

Adding VAT applies the rate to a net price. Removing VAT divides the gross price by the tax multiplier, rather than simply subtracting the percentage.

Gross = Net x (1 + rate); Net = Gross / (1 + rate)

Net: Price before VAT
Gross: Price including VAT

Worked example

At 20% VAT, a $100 net amount becomes $120 gross. Removing 20% from $120 returns $100, not $96.

Practical tips

Rates can differ by country, product and transaction date.
