Reverse VAT (Gross to Net) Mathematical Formula & Why Subtraction Fails
To remove VAT from a tax-inclusive Gross figure, you must divide by (1 + VAT Rate), never subtract the percentage directly from the Gross amount.
Net Price = Gross Total ÷ (1 + VAT Rate % ÷ 100)For a $1,100 Gross invoice including 10% VAT: Net = $1,100 ÷ 1.10 = $1,000.00 (whereas subtracting 10% would wrongly give $990).
VAT Amount = Gross Total − Net PriceFor a $1,100 Gross invoice at 10% VAT: VAT Amount = $1,100 − $1,000 = $100.00.
| VAT Rate | Reverse Divisor (Gross ÷ X) | Embedded VAT Fraction | Example ($1,200 Gross) |
|---|---|---|---|
| 8% VAT | Gross ÷ 1.08 | 2 / 27 of Gross (~7.41%) | Net: $1,111.11 | VAT: $88.89 |
| 10% VAT | Gross ÷ 1.10 | 1 / 11 of Gross (~9.09%) | Net: $1,090.91 | VAT: $109.09 |
| 20% VAT | Gross ÷ 1.20 | 1 / 6 of Gross (~16.67%) | Net: $1,000.00 | VAT: $200.00 |
| 25% VAT | Gross ÷ 1.25 | 1 / 5 of Gross (20.00%) | Net: $960.00 | VAT: $240.00 |

Frequently Asked Questions about Reverse VAT Calculator (Remove Tax: Gross → Net)
Why is subtracting 10% from a Gross price wrong when removing 10% VAT?
Because the 10% VAT was originally calculated on the smaller Net price, not the larger Gross price. A $100 Net item plus 10% VAT equals $110 Gross. If you subtract 10% of $110 ($11), you get $99 instead of $100. Dividing $110 by 1.10 restores the exact $100 Net price.
How do I remove 8% VAT from a total invoice amount in Vietnam?
Divide the total payment amount by 1.08 to find the pre-tax Net amount, then subtract the Net amount from the total to get the 8% VAT amount.
How do I calculate 20% UK reverse VAT quickly?
At 20% VAT, the embedded VAT is exactly 1/6th of the Gross price (Divide Gross by 6 to get VAT, or divide Gross by 1.20 to get the Net price).
Can I switch from Reverse VAT back to adding VAT?
Yes! Simply uncheck 'Amount includes VAT (Gross)' or click 'Add VAT (Net → Gross)' in the top bar to switch to forward VAT calculation.
