Reverse VAT Calculator
Work backwards from a VAT-inclusive price to find the original net amount and the VAT within it — instantly, accurately, and for free.
The Reverse VAT Formula
Reverse VAT calculation means working backwards from a VAT-inclusive price to find the original net amount. Because the VAT was calculated on the smaller net figure, you divide — you don’t simply subtract a percentage.
Show the Reverse VAT formula and step-by-step explanation
Step by step: convert the VAT rate to a decimal (20% becomes 0.20), add 1 (giving 1.20), then divide the gross price by that number. The result is the original net price. Subtract the net price from the gross price to find the VAT amount.
Interactive Worked Example
A freelancer receives a payment of £150.00, which is VAT-inclusive at the UK standard rate of 20%.
| Gross (VAT-inclusive) Amount | £150.00 |
| Divide by 1.2 | £150.00 ÷ 1.2 |
| Original Net Price | £125.00 |
| VAT Amount | £25.00 |
Knowing the exact net figure matters for accurate bookkeeping — the freelancer’s actual earnings before VAT are £125.00, not £150.00 or an estimate based on rough subtraction.
