How Discount Calculator helps
Enter the original price, first discount, optional second discount and sales tax.
Method and assumptions
Successive discounts multiply: final before tax = price × (1−d1) × (1−d2). A 20% then 10% discount is not 30%.
Example
An item priced at 100 with 20% and then 10% discounts costs 72 before tax.
Know the limits
