How do you calculate a discount percentage?

To calculate a discount, multiply the original price by the discount percentage and divide by 100 to get your total savings. Subtract that amount from the original price to find the final sale cost.

How do stacked or extra discounts work?

Stacked discounts are applied sequentially, not added together. An extra 20% off after a 30% discount applies to the newly reduced price, giving you a total saving higher than 30% but less than a flat 50% off.
