VAT vs Sales Tax Calculator Guide

VAT and sales tax calculations often look similar, but the practical question is usually simple: add tax to a net price or remove included tax from a gross price.

Quick workflow

A simple way to do it

  1. 1

    Choose add-tax mode when you know the net price before tax.

  2. 2

    Choose remove-tax mode when the final price already includes tax.

  3. 3

    Use percentage and bill calculators for related pricing checks.

Adding tax starts from a net price

If you know the price before VAT or sales tax, add-tax mode estimates the tax amount and final gross price.

Removing tax starts from a gross price

If the final price already includes tax, remove-tax mode estimates the original net price and included tax amount.
