Formula
Add VAT: Gross = Net × (1 + Rate ÷ 100)\nRemove VAT: Net = Gross ÷ (1 + Rate ÷ 100)
At 20%: Net × 1.20 = Gross; Gross ÷ 1.20 = Net. At 5%: Net × 1.05 = Gross; Gross ÷ 1.05 = Net. The VAT amount is always the difference between gross and net.
Worked Example
What is 100 plus VAT?
£100 net × 20% = £20.00 VAT → £120.00 gross
What is 165 plus VAT?
£165 net × 20% = £33.00 VAT → £198.00 gross
Adding VAT — B2B invoice:
A marketing agency quotes a client £4,500 net. The invoice must show the VAT-inclusive total.
£4,500 × 20% = £900.00 VAT → £5,400.00 gross
Removing VAT — retail receipt:
A business receipt shows £84.00 including 20% VAT. What is the net?
£84 ÷ 1.20 = £70.00 net • VAT = £14.00
Reduced rate (5%) — domestic energy:
A quarterly gas bill of £230 includes 5% VAT.
£230 ÷ 1.05 = £219.05 net • VAT (5%) = £10.95
Common Mistakes
- Subtracting 20% to remove VAT. £120 − 20% = £96, not £100. The correct method is £120 ÷ 1.20 = £100.
- Adding VAT twice. If a price is already VAT-inclusive, do not add VAT again. Use "Remove VAT" to verify first.
- Applying the wrong rate. Some goods qualify for the 5% reduced rate (domestic fuel, children's car seats) or 0% (most food, books).
