Calculate VAT in Reverse
Many invoices, receipts, quotations, and receipts show only the final amount including VAT.
A reverse VAT calculator works backwards to determine:
Original price before VAT
VAT amount included
Total amount including VAT
This is useful when reconciling invoices, checking supplier prices, reviewing receipts, preparing accounts, or verifying tax calculations.
What Is a Reverse VAT Calculator?
A Reverse VAT Calculator removes VAT from a VAT-inclusive amount.
Instead of adding VAT to a price, it calculates the original net value by working backwards from the total amount already including VAT.
For example:
Total Including VAT:
$120
VAT Rate:
20%
Result:
Original Price:
$100
VAT Amount:
$20
How To Use the Reverse VAT Calculator

Reverse VAT Formula
The formula used to remove VAT is:
Net Price = VAT Inclusive Price ÷ (1 + VAT Rate)
VAT Amount:
VAT = Total Price − Net Price
Example:
VAT-inclusive amount:
£240
VAT rate:
20%
Calculation:
£240 ÷ 1.20 = £200
VAT:
£240 − £200 = £40

Common Reverse VAT Mistakes
Using the Wrong VAT Rate
Different countries and products may have different VAT rates.
Subtracting VAT Directly
Many people incorrectly calculate:
Total − 20%
This does not correctly remove VAT.
The correct calculation divides by:
1 + VAT Rate
Forgetting Reduced VAT Rates
Some goods or services may qualify for reduced or zero-rated VAT.
Mixing Tax Systems
VAT rules differ between countries.
Always confirm the correct tax rate before calculating.
Why Businesses Use Reverse VAT Calculations

Improve Bookkeeping
Separate tax from the actual purchase cost.
Prepare VAT Returns
Calculate recoverable VAT accurately.
Compare Prices
Compare suppliers using net prices rather than VAT-inclusive prices.
Support Financial Reporting

Invoice Total:
€2,420
