Quick answer: VAT Calculator
To add 20% UK VAT, multiply the net price by 1.20. To remove VAT from a gross price, divide by 1.20 instead of subtracting 20%.
Example: GBP 480 net + 20% VAT = GBP 576 gross, including GBP 96 VAT.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.

- Reach for it when you already know (or can estimate) Calculation and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Rounding rules (per line vs invoice total) can change pennies - follow your auditor.
- B2B reverse-charge regimes are not modeled - this is straight percentage math.
- Zero-rated and exempt supplies need human judgment, not a single rate field.
How to use this tool
- 1Enter the net amount (before VAT).
- 2Enter the VAT percentage that applies (for example 20 for 20%).
- 3Click calculate to see VAT owed and the gross total.
- 4Use your local rules for inclusive vs exclusive pricing and rounding.

Common mistakes
- Removing VAT from a VAT-inclusive price by subtracting 20% is wrong. For standard UK VAT, divide the gross price by 1.20, then subtract the net amount to get VAT.
- Applying the 20% standard rate to reduced-rate or zero-rated goods can overcharge customers and distort records. Food, children's clothing, books, and some energy items may use different UK VAT treatment.
- Calculating VAT before applying a discount can overstate the invoice total. VAT is usually calculated on the discounted taxable amount, not the original shelf price.
