What this discount calculator does
Three offer types in one tool. % off turns an MRP and a percentage into the sale price and the rupee saving. Flat ₹ off does the reverse and also tells you the equivalent percentage, which is what the customer actually perceives. Buy X Get Y handles bundle offers — buy 2 get 1 free, buy 3 get 1 at 50% off — and reports the effective discount on the whole bundle, what the shopper pays, and the effective price per unit. Everything is rupee formatted with Indian grouping.
% off: Sale = MRP × (1 − p ÷ 100) · Savings = MRP × p ÷ 100
Flat off: Sale = MRP − f · Equivalent % = f ÷ MRP × 100
Buy X Get Y at d% off: Effective % = (Y × d) ÷ (X + Y)How to use it
Pick the offer type
% off, flat ₹ off, or Buy X Get Y.
Enter the numbers
MRP and the discount; for bundles, how many they buy, how many they get, and the discount on the extra units (100% = free). Add a unit price to see rupee amounts.
Compare
Try two versions of the same offer. A 33% bundle that moves three units may beat a 25% straight discount that moves one.
Worked examples
% off
MRP ₹1,200, 25% off. Sale = 1,200 × 0.75 = ₹900. Savings ₹300.
Flat ₹ off
MRP ₹1,200, ₹150 off. Sale = ₹1,050. Equivalent discount = 150 ÷ 1,200 = 12.5%.
Buy 2 Get 1 free
Unit price ₹500, buy 2, get 1 at 100% off.
Bundle = 3 units listed at ₹1,500. Shopper pays 2 × 500 = ₹1,000, saves ₹500. Effective discount = 1 ÷ 3 = 33.33%. Effective price per unit = 1,000 ÷ 3 = ₹333.33.
Same offer but the third unit at 50% off: shopper pays 1,000 + 250 = ₹1,250, effective discount (1 × 50) ÷ 3 = 16.67%, per unit ₹416.67.
Bundle offers decoded
| Offer | Units taken | Effective discount | Feels like |
|---|---|---|---|
| Buy 1 Get 1 free | 2 | 50% | 50% |
| Buy 2 Get 1 free | 3 | 33.33% | 50% |
| Buy 3 Get 1 free | 4 | 25% | 33% |
| Buy 1 Get 1 at 50% off | 2 | 25% | 50% |
| Buy 2 Get 2 free | 4 | 50% | 100% |
'Feels like' is the number shoppers tend to assume when the offer is read quickly — the gap is why bundles convert.
Before you announce a sale
Put the discounted price through the profit margin calculator with your real cost — a 25% discount on a 38.5% margin product leaves 17.9% on the new price, and a 30% discount leaves 12.1%. If the sale is meant to feed ads, the ROAS calculator will show the break-even moving up as the margin shrinks. More ideas for offers that do not wreck margin are in offers and discounts that increase sales.
Frequently asked questions
Is Buy 2 Get 1 free a 50% discount or 33%?
33.33%. The shopper takes three units and pays for two, so the discount on the bundle is 1 ÷ 3. It is often advertised as if it were half price because the free item is compared to one paid item instead of the whole bundle. Buy 1 Get 1 free is the offer that equals 50%.
Is a percentage discount the same as a flat discount?
Only at one price. ₹150 off a ₹1,200 item is 12.5%; the same ₹150 off a ₹600 item is 25%. Percentage offers scale with price and feel bigger on expensive items; flat offers feel bigger on cheap items and cap what you give away.
How do I combine two discounts?
Apply them one after the other, not by adding the percentages. 20% off then a further 10% off is 1 − 0.8 × 0.9 = 28% off, not 30%. Run the first in '% off', then put the result back in as the MRP for the second.
What does a discount do to my margin?
It comes straight out of the margin, and faster than you would guess. A product costing ₹400 and listed at ₹650 (38.5% margin) sold at 25% off — ₹487.50 — is left with a 17.9% margin; at 30% off (₹455) only 12.1%. The exact figure is (discounted price − cost) ÷ discounted price. Check the new price in the profit margin calculator before announcing a sale.
Can I run these offers on my own store?
Yes. A free SitesPlaced store supports percentage and flat coupons, sale prices with the MRP struck through, and Buy X Get Y offers with the free item added automatically at checkout, so you do not have to adjust orders by hand.
