Work it backwards

When you know the sale price but not the rest.

I paid after % off — what was the original price?
Marked , selling at — what discount is that really?
It costs but I want to pay — what discount do I need?
Buy get free — what is that worth?

Which deal is better?

The same item, different offers. Fill in at least two.

Discount Calculator — Calculate Discounted Prices, Savings, and MRP

Big Billion Day, Republic Day Sale, end-of-season clearance — discounts are everywhere, and so are misleading "before" prices. This calculator strips through the marketing and shows what you actually pay: stack the sale, the bank offer and the coupon, add or strip GST, set a quantity, and see the real final price with the effective discount next to it.

It also works backwards — the original price from what you paid, the true discount behind a "was ₹2,000, now ₹1,500" tag, or the discount you would need to hit your budget. And when two offers compete, it tells you which one actually wins. Everything updates as you type. No signup, no cost.

The details other calculators get wrong

  • Stacked discounts do not add up. 30% off then 10% off is 37%, not 40% — the second cut comes off what is left. Order matters too, and the breakdown shows every step.
  • Buy 1 get 1 free is 50% off, not 100%. You pay for one and leave with two.
  • The numbers always reconcile. What you save plus what you pay equals the original, exactly, every time — because the total is rounded once to your currency's real precision and the saving is derived from it.
  • Your currency is formatted its own way. ₹1,00,000 the Indian way, $100,000 the American way, and ¥1,000 with no decimals at all, because the yen has no minor unit.
  • A coupon can never pay you. A ₹500 coupon on a ₹300 item stops at zero, and only ₹300 is counted as saved.

How to Calculate Discount

1. Original Price

Enter the original or list price (MRP) before discount.

2. Discount %

Type the discount percentage advertised — 10%, 25%, 50% off, etc.

3. Auto-Calculate

The discount amount, final price, and savings appear instantly.

4. Stack Discounts

Add an extra coupon discount or bank offer to see the true effective price.

Discount Calculator Features

Multiple Discounts

Stack as many offers as you like — 30% sale + 10% bank offer + ₹100 coupon — in percentages or flat amounts, in the order they are applied. Every step is itemised.

Reverse Calculator

The original MRP from a discounted price, the real discount % behind an MRP and sale price, or the discount you would need to reach your budget.

GST Both Ways

Add GST (5%, 18% or 40% at one tap, the rates since 22 September 2025, or type any other rate) on top of the discounted price, or mark the price as tax-inclusive and see the base and tax split out of what you pay.

Total Savings and Effective %

Exactly how much money you save in absolute rupees, and the single effective discount that all your stacked offers really add up to.

Bulk Pricing

Set a quantity and get the per-item price and the line total together — useful for bulk shopping, and it accepts fractional quantities for anything sold by weight.

Which Deal Wins

Put "30% off", "₹500 off" and "buy 1 get 1 free" side by side on the same item. It reduces all three to a price per item and crowns the winner — or calls a genuine tie.

14 Currencies, Formatted Properly

Each currency uses its own grouping and decimal rules — ₹1,00,000, $100,000, and ¥1,000 with no decimals. Your choice is remembered.

Discount Calculator — FAQs

Stacked discounts apply sequentially, not additively. For 30% + 10%: First apply 30% off (₹1000 → ₹700), then 10% off the discounted price (₹700 → ₹630). The effective discount is 37%, not 40%.

Discount % = ((MRP - Sale Price) ÷ MRP) × 100. If MRP is ₹2000 and sale price is ₹1500, the discount is (500/2000) × 100 = 25%.

GST is applied on the discounted price (the actual transaction value). So if MRP is ₹1180 (₹1000 + 18% GST) and gets 10% off, GST is recalculated on the ₹900 base, making the final price ₹1062.

On the maths, yes: you pay for one, take home two, so each costs half — 50% off, not 100% off. Buy 2 get 1 free is 33.33%, and buy 3 get 1 free is 25%. The catch is that the saving only exists if you actually wanted the second one; a 40% discount on a single item you need beats a 50% BOGO on an item you do not. The comparison tool says so explicitly.

It depends entirely on the price, which is why the answer feels slippery in a shop. A percentage wins on expensive things, a flat amount wins on cheap ones, and they cross over at the point where the percentage equals the amount. On a ₹2,000 item, 30% off saves ₹600 and beats ₹500 off. On a ₹1,000 item, ₹500 off is half price and 30% off saves only ₹300. At exactly ₹2,000 a 25% discount and a ₹500 coupon are identical — the tool reports that as a tie rather than picking a fake winner.

For percentages alone, no — 30% then 10% and 10% then 30% both land on 37%. But the moment a flat coupon is involved, order changes the price. On a ₹1,000 item, taking ₹100 off first and then 30% leaves ₹630, while 30% first and then ₹100 off leaves ₹600. Retailers usually apply percentage offers before flat coupons, which is the cheaper of the two for you. List your discounts in the order the shop applies them and the breakdown will match your bill.
