About VAT Calculator

VAT Calculator is a lightweight, popup-only Chrome extension that helps you calculate VAT quickly and accurately. Enter an amount and choose a VAT rate (including quick-select options), then calculate either: (1) add VAT to a pre-tax amount to get the VAT value and final total, or (2) extract VAT from a tax-included total to find the pre-tax base and VAT portion. Results are shown instantly with a clean layout, and each value can be copied with one click. The extension runs fully offline, keeps a minimal interface, and does not require any complicated permissions.
