Single discount formula
A single percentage discount is the simplest case. The formula is:
Final = Original × (1 − Discount%/100)
Example: a ₹2,000 item with 25% off becomes 2,000 × (1 − 0.25) = 2,000 × 0.75 = ₹1,500. You save ₹500, which is exactly 25% of the original.
Stacked discounts: the trick most people miss
When you see "20% off, plus an extra 10% off", your brain wants to add the two numbers and call it 30% off. It isn't. Stacked discounts compound multiplicatively, because each new discount applies to the already-reduced price, not the original.
The correct calculation: 0.80 × 0.90 = 0.72, which means the buyer pays 72% of the original — an effective 28% off, not 30%.
Worked example: a ₹1,000 jacket marked 20% off drops to ₹800. The extra 10% off coupon then takes 10% off ₹800, not off ₹1,000. So you pay ₹800 − ₹80 = ₹720, saving ₹280 in total. A flat 30% off would have been ₹700.
Reverse calculation
If you already know the final (discounted) price and the discount percentage, you can recover the original price by dividing:
Original = Final / (1 − Discount%/100)
Example: you paid ₹1,500 and the sign said 25% off. The original price was 1,500 / (1 − 0.25) = 1,500 / 0.75 = ₹2,000. This is useful for verifying that a "sale" is actually a sale, or for back-solving the list price when a vendor only quotes the net.
FAQs
How do I calculate a percentage off?
Multiply the original price by the discount percentage divided by 100, then subtract that from the original price. The shortcut is Final = Original × (1 − Discount%/100). For example, 25% off a ₹2,000 item is 2,000 × 0.75 = ₹1,500, and you save ₹500.
If something is 20% off then 10% off, is that 30% off?
No. Stacked discounts compound multiplicatively, not additively. 20% off followed by 10% off is 0.80 × 0.90 = 0.72, which is a 28% effective discount, not 30%. On a ₹1,000 item the final price is ₹720, so you save ₹280. A flat 30% off would have been ₹700.
How do I find the original price from a discounted price?
Divide the final price by (1 − Discount%/100). For example, if you paid ₹1,500 and the tag said 25% off, the original price was 1,500 / 0.75 = ₹2,000. Use this calculator's formulas in reverse, or just plug numbers in and adjust until the final price matches what you paid.
What's the difference between a discount and a markdown?
A discount is a temporary reduction off the list price, usually tied to a promotion, customer segment, or negotiation. A markdown is a permanent reduction in the list price itself — typically because inventory isn't moving or the season has ended. Both lower what the buyer pays, but only markdowns change the reference price going forward.
