Frequently Asked Questions
How do I calculate multiple discounts applied together?
Multiple discounts are usually applied sequentially, not additively. For example, 20% off then 10% off means: Price ร 0.8 ร 0.9 = Price ร 0.72 (effective 28% off, not 30%). The second discount applies to the already-reduced price.
What is the difference between "20% off" and "20% less"?
They mean the same thing in retail contexts. Both indicate you pay 80% of the original price. However, in finance, "20% less" could refer to a reduction from a different reference point.
How do I calculate the original price from a discounted price?
Original Price = Discounted Price / (1 - Discount%/100). For example, if an item is $80 after a 20% discount: Original = $80 / (1 - 0.20) = $80 / 0.80 = $100. This is useful when you see the sale price and want to know what the item originally cost.
