How the formula works
Discount amount = original price x discount percentage / 100. Final price = original price - discount amount.
Example
A 30% discount on 80 removes 24, leaving a final price of 56 before any tax, delivery or fees. Use the double discount calculator when two reductions are applied one after another.
Common mistake
Two discounts do not usually add directly. A 20% discount followed by 10% off is not the same as a single 30% discount because the second discount is applied to a smaller price.
