VAT calculator — add or remove VAT, net to gross and gross to net, at any rate.
The totals scale by quantity; the per-item breakdown stays the same.

How to use this tool
Type the price you have — either the net price before VAT or the gross price that already includes it. This vat calculator handles both directions.
Choose 'Add VAT' if your price excludes VAT (net to gross) or 'Remove VAT' if the shelf price already includes it (gross to net). The VAT amount is always shown separately, as on an invoice.
Use a preset for common VAT rates — 20% (UK), 19% (Germany), 21%, 23%, 25% — or pick Custom and type any rate, including a reduced rate such as 5%.
You get the net price, the VAT amount and the gross price, plus the VAT share of the gross total. Add a quantity in Advanced options for multi-item totals.
Formula & worked example
Worked example: a £100 net price at the UK standard VAT rate of 20% carries £20 of VAT and costs £120 gross. Going the other way, a £120 VAT-inclusive price at 20% breaks down into £100 net plus £20 of VAT — note that the VAT is 20% of the net price but only 16.67% of the gross price. That is how to calculate VAT in both directions; try both above and they round-trip exactly.
Limitations — read this before you rely on it
This calculator applies one flat VAT rate to one price. It does not model exemptions, zero-rated or reduced-rate goods, reverse charges, cross-border rules, or rounding differences at the till. VAT rules differ by country and by product — check your tax authority for the rate that applies to your sale.
Frequently asked questions
To add VAT, multiply the net price by the rate: $100 × 20% = $20 of VAT, so the gross price is $120. To remove VAT from a gross price, divide by (1 + rate): $120 ÷ 1.20 = $100 net, so the VAT is $20.
The UK standard VAT rate is 20%. Reduced rates apply to some goods and services — for example 5% on domestic fuel and power — and some items are zero-rated or exempt. This calculator includes the 20% and 5% presets plus a custom rate.
Because the 20% is charged on the net price, not the gross price. On a $120 gross price, the VAT is $20, and $20 ÷ $120 = 16.67%. That is why you cannot just subtract 20% from a gross price — you must divide by 1.20.
VAT is charged at every stage of production with businesses reclaiming the VAT they paid, while sales tax is normally charged only to the final consumer. For a single price, though, the arithmetic is the same — both directions are handled here and in the Sales Tax Calculator.
Yes, for the arithmetic. GST in countries like Australia, India and Canada works the same way as VAT for a single price: add it with price × rate, remove it by dividing by (1 + rate). Local rules, thresholds and exemptions still apply.
