VAT calculator guide
Add VAT to a net price or remove VAT from a gross price. The calculator separates the underlying amount, VAT element and final total.
Remove VAT
Divide the gross amount by 1 plus the VAT rate to find the net amount.
VAT element
The VAT amount is the difference between the gross and net figures.
VAT rates & source
The calculator offers the three UK VAT rates published by GOV.UK. The correct VAT treatment depends on the goods or services and the circumstances of the supply.
| VAT rate | Rate | Typical treatment |
|---|---|---|
| Standard | 20% | Most goods and services |
| Reduced | 5% | Certain qualifying goods and services |
| Zero | 0% | Qualifying zero-rated goods and services |
Worked example: £100 net at 20% VAT gives £20 VAT and a £120 gross total. Removing 20% VAT from £120 gives £100 net — divide by 1.20 rather than simply subtracting 20%.

How to check the VAT result
The calculator either adds VAT to a net amount or extracts the VAT element from a VAT-inclusive amount using the selected rate. The visible UK rate information and GOV.UK source below make the assumption explicit; whether a particular product or service is standard-rated, reduced-rated, zero-rated or exempt depends on the underlying VAT rules.
