Free VAT & sales-tax calculator for 67 countries in 5 languages. Add, remove or reverse VAT, compare rates across countries, and calculate invoice margins ā no ads, no signup. For devs: a free JSON rates API (no key) and an embeddable calculator widget you can drop into any site. Rates verified May 2026.
Hi PH š
Every VAT calculator I needed was single-country, cluttered with ads, or
behind a signup ā so I built VATEstimator.
67 countries, 5 languages. Add, remove and reverse VAT, invoice breakdowns,
gross-margin math, and side-by-side rate comparison between countries.
Free, no account.
Every rate links to the official tax authority and shows the date it was last
verified. Rates move more than people expect ā Russia went 20% ā 22% this
January.
Two things I'm proud of:
ā¢ A free rates API, no key: vatestimator.com/api/v1/rates.json
ā¢ An embeddable widget for your site: vatestimator.com/embed/
Feedback welcome ā especially which features to add next.
