VAT math is simple in theory and irritating in practice. Add 20%, remove 19%, work back from a gross to a net. The ChrysoKit VAT Calculator handles every direction without making you think about formulas.
Why use it
Built for the EU and UK, but flexible enough for any country with a value-added tax. Switch between adding VAT, removing VAT, and computing VAT amount only.
How to use the VAT Calculator
- Pick the direction: add VAT, remove VAT, or VAT only.
- Enter the VAT rate.
- Enter the amount.
- Read the net, VAT and gross figures together.
Features worth knowing
Three modes
Add to net, remove from gross, or compute VAT only.
Any rate
Default presets for common rates; type your own for anything else.
Side-by-side breakdown
Net, VAT and gross are always visible together.
Pro tips
- Removing 20% VAT is not the same as taking 20% off. It is dividing by 1.20, which removes about 16.67% of the gross.
- Different goods are taxed at different rates in the same country. Confirm the rate before invoicing.
- When invoicing across borders, the place of supply rules matter. The calculator handles the math; the tax rules are a separate question.
Privacy first. The VAT Calculator runs entirely in your browser. Nothing you enter is sent to a server.
The VAT Calculator is the one to bookmark for invoicing, expense reports and anything that hits a sales tax line.

Freelancer's first quarter: VAT arithmetic that prevents surprises
The first VAT quarter of a Greek freelance business is where the calculator stops being academic. An invoice of 1,000 EUR plus 24% VAT means 1,240 lands in the account... and 240 of it was never yours. The classic first-year error is treating account balance as income: spend the 1,240 and the quarterly return arrives as a crisis. The discipline that prevents it costs one banking habit: transfer the VAT portion to a separate account the day each invoice is paid, and the quarterly payment becomes a non-event funded in advance.
The reverse calculation earns its place at pricing time. A client says their budget is 2,000 EUR all-in: your actual fee inside that number is 2000 / 1.24 = 1,612.90, a sixth less than the figure under discussion... worth knowing before agreeing, not after invoicing. Meanwhile input VAT runs the other direction: the 24% paid on the new laptop, the software subscriptions and the accountant is reclaimable against VAT collected, which is why every business expense receipt needs to show the VAT breakdown to be worth anything.
None of this is tax advice and rates and rules have exceptions an accountant should map to your specific case... but the arithmetic itself is non-negotiable, and getting it reflexive in the first quarter is considerably cheaper than learning it from the first penalty notice.
