📖 How Tax / VAT is Calculated
What is Tax / VAT?
VAT (Value Added Tax) is an indirect tax charged by the government on goods or services. The seller collects it and remits it to the government. More than 170 countries operate a VAT system.
Exclusive Mode
The amount you enter is the pre-tax base. Example: Base = 1000, Rate = 15% → Tax = 150, Total = 1150.
Inclusive Mode
The amount you enter already includes tax. Example: Total = 1150, Rate = 15% → Base = 1000, Tax = 150.
Effective Tax Rate
Effective Rate = (Tax ÷ Total) × 100 — the share of the final price that is tax.
