Margin vs Markup: Pricing Mistakes That Quietly Cut Profits
Published: 10/9/2026

A 30% markup is not a 30% margin. Confusing the two, ignoring discounts and forgetting hidden costs are the most common ways small businesses underprice. Formulas, examples and a quick price check.
"I add 30% on everything" sounds safe. But a 30% markup on cost is only about a 23% margin on the selling price, and after discounts, payment charges and wastage, the real margin can be far lower. Understanding the difference is one of the cheapest ways to improve profit.
The formulas
Markup % = (Selling price − Cost) ÷ Cost × 100
Margin % = (Selling price − Cost) ÷ Selling price × 100
Example: cost ₹100, selling price ₹130.
- Markup = 30 ÷ 100 = 30%
- Margin = 30 ÷ 130 = 23%
Quick conversion table
| Markup | Margin |
|---|
| 20% | 16.7% |
| 25% | 20% |
| 30% | 23.1% |
| 50% | 33.3% |
| 100% | 50% |
Hidden costs that eat your margin
- Discounts and offers (a 10% discount on a 23% margin item cuts margin to about 14%)
- Payment charges (card fees, MDR on larger UPI payments where applicable)
- Wastage, damage and expiry
- Free delivery and packaging
- Credit sales that are paid late, or never
Price-check your top 20 items
- List your top 20 items by revenue.
- Note the latest purchase cost (including freight).
- Calculate the margin at your actual average selling price after discounts.
- Mark items below your target margin.
- Decide: raise the price, renegotiate cost, reduce discounting or accept low margin deliberately (for example, a traffic-builder item).
Set targets by category, not one rule for all
Fast-moving staples often carry thin margins; accessories, specialty and private-label items can carry more. A single markup across the shop leaves money on the table in some categories and loses customers in others.
Where BizFlow fits
BizFlow shows margin by item and category using actual purchase costs and real selling prices after discounts, so you can see which items earn and which quietly lose money. See owner dashboards.
