📖 Deep Dive: VAT Calculator

Why a VAT calculator

When dealing with VAT regions like the EU and UK, quotes often switch between tax-inclusive and tax-exclusive, and hand calculation easily goes wrong.

How it works

Add tax: gross equals net times (1 plus rate). Remove tax: net equals gross divided by (1 plus rate), tax equals gross minus net. The formulas are symmetric, just in opposite directions.

A quick example

Net 100, rate 20% - add tax gives gross 120. Reverse: gross 120 remove tax gives net 100, tax 20.
