Discount Formulas — Explained with Examples

Simple Discount
Savings = Price × Discount% ÷ 100
Final = Price − Savings

Example: ₹1,000 @ 30% off → Save ₹300, Pay ₹700

Reverse: Find Original Price
Original = Sale Price ÷ (1 − Discount% ÷ 100)

Example: Paid ₹840 after 30% off → Original = 840 ÷ 0.70 = ₹1,200

Successive Discounts
Net% = 100 − [(1−d1/100)×(1−d2/100)×100]

Example: 30% + 20% ≠ 50%. Net = 100−(0.7×0.8×100) = 44% off

Key insight: Two successive discounts of 30% + 20% = only 44% net discount — not 50%. Always use the successive discount formula to avoid being misled by stacked offers.

Frequently Asked Questions

Discount % = ((Original Price − Sale Price) ÷ Original Price) × 100. For example, if an item's MRP is ₹1,000 and you buy it for ₹700, the discount = (300 ÷ 1000) × 100 = 30%.

Final Price = Original Price × (1 − Discount ÷ 100). For example, ₹2,000 with 25% off = ₹2,000 × 0.75 = ₹1,500. You save ₹500.

A stacked discount applies multiple discounts sequentially. For example, '30% + 20% off' means first 30% is applied, then 20% on the reduced price. On ₹1,000: After 30% = ₹700, after 20% more = ₹560. Net discount = 44%, NOT 50%. Use the formula: Net = 100 − [(1−d1/100)×(1−d2/100)×100].

As per GST rules, if a discount is mentioned on the invoice at the time of supply, GST is calculated on the discounted price (after discount). If the discount is given later as a post-sale credit note, GST is originally charged on the full price. Always verify discounts are pre-invoice for correct GST treatment.

Original Price = Sale Price ÷ (1 − Discount% ÷ 100). For example, if you paid ₹840 after a 30% discount: Original Price = 840 ÷ 0.70 = ₹1,200. This is useful when you know the sale price and discount rate but want to verify the MRP.

The maximum safe discount equals your gross margin percentage. If your gross margin is 40% (cost ₹600, sell ₹1,000), you can discount up to 40% and break even. Any discount beyond your margin = selling at a loss. Merchants use loss leaders strategically, but it must be a calculated decision.

E-commerce platforms typically show discount as ((MRP − Selling Price) ÷ MRP) × 100. However, MRP is often inflated — compare the selling price against similar items. Also note that 'additional bank offer' or 'coupon code' discounts are applied on the already-discounted selling price, making them successive discounts.

EMI offers like 'No Cost EMI' often include hidden processing fees or slight price inflation. Effective discount = (MRP − actual cash equivalent paid including all fees) ÷ MRP × 100. Always calculate the total outflow across all EMIs vs the one-time cash price to find the real discount.
