Discount Calculator

Discount price = Original price × (1 − discount %). Example: ₹2,000 item with 25% off = 2000 × 0.75 = ₹1,500. Saving = ₹500. Quick mental math: 10% off ₹2,000 = ₹1,800; 25% off = three-quarters of original. For staircase discounts (10% then 5%), apply sequentially: ₹2,000 × 0.90 = ₹1,800; then × 0.95 = ₹1,710. That's not the same as a flat 15% off (which would be ₹1,700). The calculator handles single, stacked, and conditional discounts with full breakdowns.

20% off means you pay 80% of the original. ₹500 × 0.80 = ₹400. So 20% off ₹500 is ₹400, with savings of ₹100. Quick calculation: 20% of any price = price ÷ 5. ₹500 ÷ 5 = ₹100. Subtract from original = ₹400. For ₹1,250 with 20% off: 1250/5 = ₹250. New price = ₹1,000. The mental shortcut for 20% (divide by 5) saves time when shopping. The calculator handles any percentage instantly and shows the savings clearly.

Stacked discounts apply sequentially, not added together. A 30% + 20% stacked discount is NOT 50% off. Apply 30% first, then 20% on the reduced price. Example: ₹1,000 × 0.70 = ₹700; then × 0.80 = ₹560. Total saving = ₹440, or 44% — not 50%. Order doesn't matter for percentages: same final number either way. Some retailers stack a flat amount on top of a percentage (₹100 off + 20%): ₹1,000 × 0.80 = ₹800, then − ₹100 = ₹700. That depends on terms. The calculator handles all stacking patterns.

Original price = Discounted price / (1 − discount %). Example: you paid ₹2,400 after 25% off. Original = 2400 / 0.75 = ₹3,200. Discount amount = ₹800. Quick check: ₹3,200 × 0.75 = ₹2,400 ✓. This is useful when you're comparing offers across stores or verifying advertised "Was/Now" prices. Some retailers inflate the "original" price before discounting — common during sale season. Cross-check with the regular price you've seen before. The calculator solves for original price, discount amount, or discount percentage, depending on what's known.

No, they're not the same. A discount reduces the price you pay upfront. Cashback gives you money back later — usually credited to a wallet, card statement, or bank account, sometimes after a delay. A 10% discount on ₹1,000 means you pay ₹900. A 10% cashback means you pay ₹1,000 and receive ₹100 later. The cash flow impact is different. Cashback often has minimum spend requirements, expiry dates, or restrictions on use. From a pure rupee perspective, instant discount is usually preferable. The calculator can compare both side by side.

Apply discount first, then add tax (most common in India and US retail). Example: ₹1,000 item, 20% discount, 18% GST. Discounted price = ₹800; GST on ₹800 = ₹144; final price = ₹944. If tax is applied first: ₹1,000 + ₹180 = ₹1,180; then 20% off = ₹944. Same answer because both operations are multiplicative — but the order can matter if there's a flat fee in the mix. Always check the receipt sequence. Some retailers use one method, others another. The calculator handles both orderings transparently.

Buy One Get One (BOGO) effectively halves the per-unit price for the deal. Two items at ₹500 each, BOGO free → total ₹500 for two = ₹250 per unit, or 50% effective discount. BOGO 50% off (second item half-price): two at ₹500 → ₹500 + ₹250 = ₹750 for two = ₹375 per unit, or 25% effective discount. Compare BOGO offers to flat percentage discounts on a per-unit basis to know if you're really saving. Many shoppers buy unnecessary extras to "qualify" — the saving evaporates if you didn't need the second item. The calculator computes effective per-unit price.
