How to use VAT Calculator
This VAT calculator adds or removes value-added tax at any rate, giving you the net price, the VAT amount and the gross total in one step. Switch to "add VAT" to find the tax-inclusive price from a net figure, or "remove VAT" to back out the tax already included in a gross price on an invoice or receipt. Built-in rate presets and a country reference table make it easy whether you are pricing goods, reclaiming tax or checking a supplier bill.
- Choose whether to add VAT to a net price or remove it from a gross price.
- Enter the amount you want to convert.
- Set the VAT rate, or tap a preset such as 20% or 23%.
- Read the net, VAT and gross figures instantly.
- Use the country table to confirm the correct rate for your region.

How adding and removing VAT works
To add VAT, multiply the net price by the rate and add it back: gross = net × (1 + rate). To remove VAT from a tax-inclusive price, divide by one plus the rate: net = gross ÷ (1 + rate), and the difference is the VAT. Removing VAT is not the same as simply subtracting the percentage — a 20% rate means you divide by 1.20, which is why a £120 gross price contains £20 of VAT, not £24.
| Country | Standard rate | Type |
|---|---|---|
| United Kingdom | 20% | VAT |
| Ireland | 23% | VAT |
| Germany | 19% | VAT |
| Australia | 10% | GST |
| UAE | 5% | VAT |
When to add versus remove VAT
Businesses quoting prices to other VAT-registered companies usually show net prices and add VAT at checkout, while consumer prices are typically shown gross. If you receive an invoice with a tax-inclusive total and need to record the net cost and the reclaimable VAT separately, use the remove-VAT mode. Getting this right matters for bookkeeping, tax returns and accurate margin calculations on the products you sell.
