The practical guide
See each step between the original price and checkout total.
The calculator applies the stated percentage discount, multiplies by quantity, and can add tax to the discounted subtotal.
Quantity and tax
Quantity multiplies the discounted unit price. Optional tax is then calculated on the discounted subtotal in this workflow.
Sequential discounts differ
Two successive discounts are applied one after another and are not normally equal to adding the percentages together.
