About Discount Calculator
A discount calculator shows the real price of something on sale and how much money you keep in your pocket. Enter the original price, or MRP, and the percentage off, and the tool instantly gives you the sale price along with the amount saved. It is handy during festive sales, end-of-season offers and online deals where the price tag says 40% off but the final number is not obvious.
Shoppers use it to compare offers across stores, shop owners use it to set sale prices, and students use it to check percentage homework. The calculator handles one discount at a time, from 0% to 100%, and works with any currency as long as you enter plain numbers. If a deal stacks two discounts, simply run the second one on the new sale price.
Features
- Shows the final sale price and the amount saved together
- Accepts decimal prices and decimal discount percentages
- Validates that the discount stays between 0% and 100%
- Works with rupees or any other currency
- Amounts shown with 2 decimals and Indian digit grouping, with copy and reset buttons
Why use it
- Check whether a sale is really a good deal before you buy
- Avoid mental-maths mistakes at the checkout
- Set accurate sale prices for your shop or listings
- Understand stacked offers by applying them one at a time
Formula used
Savings = price×discount/100; sale price = price−savings.
Examples
40% off a ₹2,499 jacket
Input: Original price 2499, Discount 40%
Result: Sale price: 1,499.40
Savings: 999.60
You pay ₹1,499.40 and save ₹999.60.
Second of two stacked 10% discounts
Input: Original price 1080 (the sale price after a first 10% off ₹1,200), Discount 10%
Result: Sale price: 972.00
Savings: 108.00
Two successive 10% discounts take ₹1,200 down to ₹972, a total cut of 19%, not 20%.
15% off an online order
Input: Original price 1200, Discount 15%
Result: Sale price: 1,020.00
Savings: 180.00
The order costs ₹1,020 after the discount.
Discount Calculator: frequently asked questions
How do I calculate a discount percentage manually?
Multiply the original price by the discount percentage and divide by 100 to get the savings, then subtract the savings from the original price. For ₹2,499 at 40% off, the savings are 2499 × 40 ÷ 100 = ₹999.60 and the sale price is ₹1,499.40. This calculator does exactly that and shows both numbers so you do not have to work it out by hand.
Do two 10% discounts equal a 20% discount?
No. The second discount is applied to the already reduced price, so the combined effect is smaller. On a ₹1,200 item, 10% off gives ₹1,080, and another 10% off gives ₹972, which is a total reduction of 19%. To handle stacked offers here, run the calculator twice, using the first sale price as the new original price.
Can the discount be more than 100%?
No. A discount above 100% would mean the seller pays you, so the tool only accepts values from 0 to 100 and shows an error otherwise. A 100% discount gives a sale price of 0. Negative discounts are also rejected, because a price increase is a markup rather than a discount.
Is the discount applied before or after GST?
That depends on the seller. In India, a discount shown on the invoice before tax is usually deducted first, and GST is then charged on the reduced price. If you want the final amount including tax, calculate the sale price here and then add GST to it with the GST calculator. Always check your bill for the exact treatment.
How is the result rounded?
Sale price and savings are shown to 2 decimal places with Indian digit grouping, for example Sale price: 1,499.40 and Savings: 999.60, so the figures read like rupees and paise. The calculation itself runs at full precision before this display rounding. If your store rounds to the nearest rupee, round the displayed figure the same way.
