FAQ
What does 20% off mean?
20% off means you pay 80% of the original price. For example, a $100 item at 20% off costs $80.
How to calculate stacked discounts?
Calculate sequentially. For example, 20% off then 10% off: $100 × 0.8 × 0.9 = $72, equivalent to 28% off total.
What's the difference between discount and coupon?
Discounts are usually percentage-based, while coupons may offer fixed amount off or minimum purchase deals. This calculator supports both.
