How do I calculate a 20% discount?

Discounted price = Original price × (1 - 20/100) = Original price × 0.80. For example, 20% off ₹1,000 = ₹1,000 × 0.80 = ₹800. You save ₹200.

How do I calculate the original price from a discounted price?

Original price = Sale price / (1 - Discount%). If a product costs ₹600 after a 25% discount, original = 600 / 0.75 = ₹800.

What is the difference between 20% off and 20% discount?

These mean the same thing. "20% off" and "20% discount" both mean the price is reduced by 20% of the original price.

How does stacked/double discount work?

A stacked discount multiplies the savings. 20% off, then an additional 10% off = 1 - (0.80 × 0.90) = 1 - 0.72 = 28% total discount, NOT 30%.

What is the best way to compare discounts?

Always compare the final price, not just the discount percentage. A 50% off item that was overpriced may be more expensive than a 20% off item at a fair price.

About Discount Calculator

Our Discount Calculator makes shopping math easy. Enter the original price and the discount percentage, and instantly see the sale price, the rupee amount you save, and verify the savings percentage. Or work backwards — enter the original and sale price to calculate what percentage discount was applied.

This tool is perfect for shoppers comparing deals online, retailers calculating promotional prices, and students studying percentage problems. During sale seasons like Diwali, Big Billion Day, or Black Friday, quickly compare discounts across products to find the best deal.

The calculator also handles stacked discounts (discount on top of discount), which are common in retail. For example, an additional 10% off on an already 20%-discounted item is not the same as 30% off — our tool shows you the correct combined discount.
