About Excise Duty Calculator

Excise can be charged on value, on quantity, or on both. Ad valorem duty rises with price while specific duty per unit does not, so the effective burden on cheap goods is heavier under a specific regime.

Formula

Excise duty

Duty = assessable value × rate + quantity × specific duty per unit
