About this VAT / Tax Calculator
VAT (Value-Added Tax) and sales tax show up on almost every invoice you issue or receive. This calculator handles both directions in one click: enter a net price and a rate to compute the tax and gross amount, or paste a gross figure and back-calculate the original net total. It supports any percentage so it works for UK 20%, EU rates from 17–27%, GCC 5–15%, and US sales tax of any value. Numbers update instantly with two-decimal precision suitable for invoices and quotes.
