Useful for both sides of the counter
When you're running a sale or a coupon offer, you need to know the final price you'll actually charge — and what it costs you in margin. This calculator gives you both instantly, for any discount percentage.
It's also handy for checking a supplier's discount offer on a bulk order, or for quickly answering a customer's "how much is that after the discount" question without reaching for a phone calculator.
Discount formula
Discount amount (You save) = Original price × Discount % ÷ 100. Final price = Original price − Discount amount. Put together, Final price = Original price × (100 − Discount %) ÷ 100.
How to use the discount calculator
- 1Enter the Original price: the MRP, list price or menu price before the offer.
- 2Enter the Discount as a percentage, for example 15 for 15% off. Decimals such as 12.5 work too.
- 3Read You save, the rupee value of the discount on that item or bill.
- 4Read Final price, the amount the customer pays after the discount.
- 5To compare offers, change only the discount figure; both results update as you type.
Worked example: 25% off a ₹1,800 shirt
A clothing shop lists a shirt at ₹1,800 before GST and plans a 25% festive promotional discount. The discount calculator shows You save ₹450 (₹1,800 × 25 ÷ 100) and a Final price of ₹1,350. The shirt costs the shop ₹1,080, so profit per shirt falls from ₹720 to ₹270, a drop of 62.5%. To earn the same total profit as before, the sale has to move about 2.7 times as many shirts (₹720 ÷ ₹270 = 2.67).
Multi-buy offers can be compared the same way. Buy 2, get 1 free on ₹600 items means the customer pays ₹1,200 for three pieces, or ₹400 each. Enter ₹600 and 33.33% and the calculator returns a final price of ₹400.02, the 2 paise being rounding, so the offer equals a one-third discount on every piece. That is deeper than 25% off, though it also moves three pieces per customer instead of one.
Before you announce a discount
- Check the final price still covers your cost price plus per-sale costs such as packaging, delivery commission and card charges.
- Convert flat offers to a percentage to compare them: ₹100 off is 25% on a ₹400 bill but only 10% on a ₹1,000 bill.
- For packaged goods, quote the discount from the printed MRP. You can sell below MRP, never above it.
- Set an end date or a minimum bill value so a promotion does not quietly become your regular price.
- After the offer, compare units sold with the extra volume you needed. If sales did not rise enough to cover the lost margin, change the offer before repeating it.
Discount calculator FAQs
Discount Amount = Original Price × Discount % ÷ 100. Final Price = Original Price − Discount Amount. A ₹500 item at 20% off saves ₹100, for a final price of ₹400.
A discount reduces your selling price but not your cost, so it eats directly into margin. Check the profit margin calculator on the discounted price before running a promotion to make sure it's still worth selling at.
Apply them one after another rather than adding the percentages — a 20% discount followed by a further 10% off is not a 30% total discount. Run the first discount through the calculator, then run the result through again for the second discount.
Yes. Setu Dine supports configurable coupons and discounts that apply automatically at the bill, so staff don't need to calculate offers manually at the counter.
Subtract the sale price from the original price, divide by the original price and multiply by 100. An item marked down from ₹2,000 to ₹1,500 carries a discount of ₹500 ÷ ₹2,000 × 100 = 25%. This calculator works forward from a percentage, so enter the figure you get to confirm the final price matches what you planned.
When the discount is given at or before the time of sale and shown on the tax invoice, GST is charged on the discounted price. A ₹1,000 item with 10% off and 18% GST is billed at ₹900 plus ₹162 GST, a total of ₹1,062. Discounts given after the sale, such as year-end supplier rebates, follow stricter conditions, so check the treatment with your CA.
A discount is usually a temporary or conditional reduction, such as a festive offer, coupon or bulk-order rate, after which the price returns to normal. A markdown is a permanent cut to the selling price, often used to clear slow-moving or end-of-season stock. Both reduce your margin in the same way, and this calculator works out the new price for either.
