Discount Strategies: How to Price Promotions Running a discount without modelling the margin impact is one of the most common and costly mistakes in retail and e-commerce. A sale can increase revenue while simultaneously destroying profit — especially when discounts are large, margins are thin, or the volume uplift is overestimated. --- What is Margin Impact Formula? Before setting any promotion, calculate what happens to your unit economics: Example: Product selling price: ₹1,000 COGS: ₹600 Current gross margin: ₹400 (40%) Apply a 20% discount (new price: ₹800): Margin After = ₹800 − ₹600 = ₹200 Margin % After = 200/800 = 25% The discount compressed margin from 40% to 25% — a 37.5% reduction in margin, not 20%.

Frequently Asked Questions
What is a discount pricing strategy?
A discount pricing strategy involves temporarily or permanently reducing product prices to drive sales volume, clear inventory, acquire customers, or compete on price. Common forms include percentage-off sales, BOGO (buy one get one), bundle pricing, loyalty discounts, and seasonal promotions. The key is ensuring the volume increase justifies the margin compression — a poorly planned discount can sell more units but make less total profit.
How do I calculate the margin impact of a discount?
Start with your current gross margin percentage. When you apply a discount, margin is compressed because your cost stays the same while your revenue drops. Formula: New Margin % = ((Original Price × (1 − Discount%) − COGS) / (Original Price × (1 − Discount%))) × 100. A 20% discount on a product with 40% margin doesn't halve the margin — it drops it to about 25%, a 37.5% reduction in margin percentage.
What percentage discount is effective for driving sales?
Studies suggest customers don't perceive discounts below 15% as compelling. The psychological sweet spots are 20%, 25%, 33%, and 50% — round numbers that communicate a clear saving. For luxury goods, even small absolute discounts (10%) signal exclusivity erosion. For high-volume FMCG, 5–10% can move significant volume. The right discount depends on category, competitive pricing, and your margin structure.
How do I calculate break-even on a promotion?
Break-even lift = Margin before discount / Margin after discount − 1. This tells you how much sales volume must increase for the promotion to maintain the same gross profit. Example: if a 20% discount drops your unit margin from ₹40 to ₹20, you need to sell 2× as many units just to break even on gross profit. Any volume less than 2× and you made less total profit than without the sale.
What is anchor pricing?
Anchor pricing is a psychological pricing technique where a higher reference price (the 'anchor') is displayed alongside the sale price to make the discount appear larger. Example: showing 'Original: ₹2,999, Sale: ₹1,499' makes ₹1,499 feel like a bargain even if the product was never actually sold at ₹2,999. It exploits the anchoring cognitive bias. Many countries have regulations requiring that anchor prices reflect prices the product was genuinely sold at.
