How discounts are calculated
Sale price = original price × (1 − discount ÷ 100). A second discount applies to the already reduced price, so 20% off and then 10% off is 28% off in total, not 30%.
Frequently asked questions
How do I calculate 25% off?
Multiply the price by 0.75. For example, 25% off 80 is 80 × 0.75 = 60, a saving of 20.
Is tax added before or after the discount?
Usually after: tax is charged on the reduced price. Enter your local sales tax or VAT rate in the calculator to include it.
