Enter your cost price and selling price. The calculator gives profit margin %, markup %, and profit amount instantly. Switch tabs to calculate markup or reverse-engineer the selling price from a target margin.

Markup is 50%, but margin is only 33.3%

Margin vs markup, the number that trips everyone up

My friend Arjun runs a small electronics shop in Coimbatore. He buys a Bluetooth speaker for ₹800 and sells it for ₹1,200. He tells customers “I make 50% profit.” He’s quoting the markup. His actual margin is 33.3%.

This distinction matters when you’re pricing products or comparing to industry benchmarks. Most industries quote margins, not markup.

Margin is profit as a percentage of the selling price. Markup is profit as a percentage of the cost. Same rupee profit, different percentages. The formula:

Margin % = (Sell – Cost) ÷ Sell × 100

Markup % = (Sell – Cost) ÷ Cost × 100

A 100% markup means you doubled your cost. The margin on that? 50%. Never the same number (unless profit is zero).

Typical margins by business type in India

Margins vary enormously. Comparing your business to the wrong benchmark is useless.

Business typeGross margin range
Retail grocery / kirana8–15%
Garments / apparel retail40–60%
Restaurant / food service60–70% (on food cost)
Electronics retail5–12%
Pharma retail18–25%
SaaS / software70–85%
Freelance services60–80%
Manufacturing (FMCG)35–55%

Low margin is not the same as low profit. A kirana doing ₹10 lakh/month at 10% margin earns ₹1 lakh. A boutique doing ₹1 lakh/month at 60% margin earns ₹60,000.

GST and your selling price

This is where Indian sellers constantly get confused. GST is collected on the selling price and passed to the government. It is not your revenue.

If you price a product at ₹1,000 with 18% GST:

  • Customer pays ₹1,180
  • You receive ₹1,000 (net of GST)
  • Your margin calculation should use ₹1,000 as the selling price, not ₹1,180

If you set prices inclusive of GST and forget to back-calculate, your actual margin is lower than you think. A product “sold at ₹1,180” with ₹800 cost is not a 47.4% margin, it’s 21.2% after removing GST.

Use the GST Calculator to separate the tax component before running margin calculations.

Finding the right selling price

The reverse tab on this calculator answers: “I want a 40% margin. My cost is ₹600. What should I charge?”

The formula: Selling price = Cost ÷ (1 – Margin %)

So: ₹600 ÷ (1 – 0.40) = ₹600 ÷ 0.60 = ₹1,000

Common mistake: people add 40% on top of cost (markup method), getting ₹840. That gives 28.6% margin, not 40%. The division method is the correct one for margin-based pricing.

Break-even and margin together

Margin tells you profitability per unit. Break-even tells you how many units to cover fixed costs. Both matter.

If your fixed monthly costs are ₹50,000 and margin per unit is ₹200 (selling ₹500, cost ₹300):

  • Break-even = ₹50,000 ÷ ₹200 = 250 units/month
  • Below 250 units you lose money regardless of what the margin % looks like

The margin calculator handles per-unit math. For EMI on business loans or capital, check the EMI Calculator.
