Frequently Asked Questions
How do you calculate discount percentage?
Discount Percentage = ((Original Price - Sale Price) / Original Price) × 100. For example, an item marked down from $80 to $60: ((80-60)/80) × 100 = 25% off.
Can you add stacked discounts together?
No. A 20% discount followed by a 10% discount is NOT 30% off. The second discount applies to the already-reduced price. 20% + 10% stacked = 28% total discount. Each subsequent discount has a smaller dollar impact.
How do I find the original price before a discount?
Original Price = Sale Price / (1 - Discount%/100). For example, if an item is $60 after 25% off: $60 / (1 - 0.25) = $60 / 0.75 = $80.
