Find sale price, savings amount, original price or discount percentage — instantly and for free.
Sale Price = Original Price × (1 − Discount% / 100). For example, 20% off ₹500 = 500 × 0.80 = ₹400. You save ₹100.
Original Price = Sale Price ÷ (1 − Discount% / 100). For example, if sale price is ₹800 at 20% off: 800 ÷ 0.80 = ₹1000 original price.
Discount% = (Original Price − Sale Price) ÷ Original Price × 100. For example, original ₹1000, sale ₹750: (250 ÷ 1000) × 100 = 25% discount.
A flat discount deducts a fixed amount (e.g., ₹200 off). A percentage discount deducts a % of the price (e.g., 20% off). For high-value items, percentage discounts save more.
Add all item prices to get the total, then apply the discount% to the total using our Sale Price mode.
Sale season in India — Flipkart Big Billion Days, Amazon Great Indian Festival, Meesho sales — is exciting, but the discount labels can be misleading. "60% off" on a product with an inflated MRP, or "flat ₹500 off" on a ₹2,000 item vs a ₹500 item, are very different deals. Knowing the maths helps you shop smarter.
A percentage discount scales with price — 20% off ₹10,000 saves you ₹2,000, while 20% off ₹500 saves only ₹100. A flat discount saves the same fixed amount regardless of price — ₹500 off is ₹500 off, whether the item costs ₹600 or ₹6,000. For low-priced items, flat discounts are usually better. For high-priced items, percentage discounts often save more.
When a product shows "30% off + extra 10% off with bank card", these discounts are not added — they're applied sequentially. Example: ₹1,000 product, 30% off = ₹700, then 10% off ₹700 = ₹630. The effective discount is 37%, not 40%. Use our calculator twice: first apply the primary discount, then apply the secondary discount to the result.
In India, GST is charged on the post-discount price when the discount is shown on the invoice. So if an item is ₹1,000 (before GST) and you get 20% off, GST is calculated on ₹800, not ₹1,000. However, some sellers show MRP inclusive of GST — in that case, the discount is already factored in.
Many e-commerce products show a "MRP" that's significantly above the actual market price. Always check: if the item was selling for ₹2,000 last month and is now ₹1,800 with a label saying "30% off MRP ₹2,571" — your real saving compared to normal price is only 10%, not 30%. Use the Discount % mode with the original street price and current sale price to find the actual saving.
