Frequently Asked Questions

How do I calculate a discount percentage?

Subtract the sale price from the original price, divide by the original price, and multiply by 100. If an item is marked down from $80 to $60: ($80-$60)/$80 x 100 = 25% discount.

What is the difference between percentage discount and dollar discount?

A percentage discount scales with price (20% off a $100 item saves $20, but 20% off a $500 item saves $100). A flat dollar discount ($20 off) saves the same amount regardless of price. Percentage discounts feel larger on expensive items; dollar discounts feel larger on cheap items.

How do stacked discounts work?

Stacked discounts are applied sequentially, not added together. A 20% discount followed by an additional 10% discount is not 30% off. Instead: $100 x 0.80 = $80, then $80 x 0.90 = $72. The combined discount is 28%, not 30%.
