What is this tool?

This tool calculates Value Added Tax (VAT) in either direction: add VAT to a price that excludes tax, or remove VAT from a price that already includes it, so you can see the tax amount and the other value either way.

Example

Example (Add VAT): an exclusive amount of 1,000 with 20% VAT gives a VAT amount of 200 and a total of 1,200. Example (Remove VAT): an inclusive amount of 1,200 at 20% VAT gives back an exclusive amount of 1,000 and VAT of 200.

How it works

Add VAT: VAT amount = amount x (rate / 100); total = amount + VAT amount. Remove VAT: exclusive amount = inclusive amount x (100 / (100 + rate)); VAT amount = inclusive amount - exclusive amount. Both are standard percentage-based VAT formulas, computed directly in JavaScript.
