Use this free online discount calculator to find out exactly how much you save on a sale and what the final price will be. Just enter the original price and discount percentage to get instant, accurate results for shopping or billing.
How to Use the Discount Calculator
Enter the "Original Price (₹)" of the item before any discount.
Enter the "Discount (%)" being offered on that item.
Click "Calculate Discount" to instantly see the Discount Amount and Final Price.
How the Discount Is Calculated
Discount amount: Original Price × Discount % ÷ 100
Final price: Original Price − Discount amount, which is the same as Original Price × (100 − Discount %) ÷ 100
For example, 25% off a ₹2,499 kurta is 2,499 × 25 ÷ 100 = ₹624.75, so you pay ₹1,874.25. The discount percentage must be between 0 and 100; anything above 100% would mean the shop is paying you.

Stacked Discounts Do Not Simply Add Up
Sales often advertise offers like "Flat 40% off + extra 10% off". The second discount is applied to the already reduced price, not to the original, so the combined discount is less than the sum of the two.
On a ₹4,999 pair of shoes, 40% off brings the price to ₹2,999.40. The extra 10% is then taken from ₹2,999.40, saving ₹299.94 and leaving ₹2,699.46. That is a total discount of 46%, not 50%. To work this out here, run the calculator twice: first with 40% on the original price, then with 10% on the result.
A quick way to combine two discounts: multiply what is left after each one. After 40% off you pay 0.6 of the price, after a further 10% you pay 0.9 of that, and 0.6 × 0.9 = 0.54, so you pay 54% of the original. The same works for "50% + 20%": 0.5 × 0.8 = 0.4, a 60% total discount.
Reading Offers in Indian Shops and Online Sales
MRP already includes GST. A discount on the MRP reduces the price you pay, and the seller cannot add GST on top of a tax-inclusive MRP.
Bank card offers usually have a cap. "10% instant discount up to ₹1,500" means you get 10% only on purchases up to ₹15,000. On a ₹40,000 phone the discount is still ₹1,500, which is effectively 3.75%.
Buy-one-get-one deals are percentage discounts in disguise. Buy 1 get 1 free on items of the same price is 50% off each, and buy 2 get 1 free is about 33.3% off. If the free item is the cheaper one, the real discount is lower.
Check the "original" price. A discount is only meaningful if the struck-out price is what the item normally sells for. Comparing the final price across sellers tells you more than the percentage does.
Working Backwards From a Sale Price
If you know the sale price and the discount but not the original price, divide the sale price by (1 − discount ÷ 100). A shirt selling for ₹1,874.25 after 25% off had an original price of 1,874.25 ÷ 0.75 = ₹2,499. To find what discount you actually got, divide the saving by the original price and multiply by 100.
Frequently Asked Questions
The calculator multiplies the original price by the discount percentage and divides by 100: Discount = (Original Price × Discount %) / 100. The Final Price is then the Original Price minus that Discount Amount.
Yes. It works for any percentage-off scenario, including store sales, coupon codes, or bulk order discounts — just enter the listed price and the discount percentage being applied.
No. The extra 10% is taken from the already discounted price, so the combined discount is 46%. Multiply the remaining fractions, 0.6 × 0.9 = 0.54, to see that you pay 54% of the original price.
Divide the discounted price by (1 − discount ÷ 100). For example, ₹1,500 after a 25% discount means the original price was 1,500 ÷ 0.75 = ₹2,000.
For retail items sold at MRP, the price already includes GST, so simply apply the discount to the MRP. On a business invoice, a discount shown on the invoice is normally deducted first and GST is then charged on the reduced value.
