Sale season, shopping festivals, Flipkart Big Billion Days, Amazon Great Indian Sale — discounts are everywhere. But is that 40% off actually a good deal? And how do you quickly figure out what you are actually paying? This guide shows you how to calculate discounts instantly.
How to Calculate Percentage Off — The Formula
Sale Price = Original Price × (1 − Discount% / 100). Example: ₹2,000 item with 30% off = ₹2,000 × 0.70 = ₹1,400. Amount saved = ₹2,000 − ₹1,400 = ₹600. Quick mental trick: for 10% off, move the decimal one place left. For 25% off, take half then half again.

Find What Percentage Off Something Is
If you know the original price and the sale price but want to know the discount percentage: Discount% = ((Original − Sale) / Original) × 100. Example: Original ₹5,000, Sale ₹3,500. Discount = ((5000 − 3500) / 5000) × 100 = 30%. That is a 30% discount.
Markup vs Discount — What Sellers Need to Know
Discount and markup are opposites but often confused. Discount is calculated on the selling price (consumer side). Markup is calculated on the cost price (business side). If you buy an item for ₹100 and sell for ₹150, markup = 50%. But the discount from ₹150 to ₹100 is 33.3% — not 50%.
