Profit Margin vs Markup: Formulas, Conversion Table and How to Price With GST

Quick answer: margin and markup both start from profit (price − cost), but margin divides it by the selling price and markup divides it by the cost. An item that costs ₹700 and sells for ₹1,000 has a ₹300 profit, a 30% margin and a 42.9% markup. To price for a target margin, use price = cost ÷ (1 − margin). Add GST after you set the price.

Try it with the profit margin calculator. This article explains when to use each number and how to avoid pricing mistakes that quietly eat profit.

Two ratios, one profit

Margin can never reach 100%, because profit can never exceed the selling price. Markup has no ceiling: a product that costs ₹100 and sells for ₹500 has a 400% markup but an 80% margin.

Why the difference matters

Suppose a distributor tells the sales team, "we need a 25% margin", and the team adds 25% to cost. On a ₹10,00,000 order costed at ₹8,00,000:

• Intended margin of 25%: price should be 8,00,000 ÷ 0.75 = ₹10,66,667, profit ₹2,66,667
• Markup of 25% applied: price becomes ₹10,00,000, profit ₹2,00,000, margin only 20%

A ₹66,667 difference on one order, simply from confusing two percentages. Across a year of orders, that is the gap between a healthy business and a struggling one.

Conversion table

Formulas:

• Margin from markup = markup ÷ (100 + markup) × 100
• Markup from margin = margin ÷ (100 − margin) × 100

Setting a price

For a target margin

Price = cost ÷ (1 − target margin)

Cost ₹750, target margin 25%: 750 ÷ 0.75 = ₹1,000.

For a target markup

Price = cost × (1 + markup)

Cost ₹750, markup 25%: 750 × 1.25 = ₹937.50.

What belongs in "cost"

The answer changes with the question you are asking.

• Gross margin uses the cost of goods sold: purchase price, freight inward, import duty, packing and direct labour.
• Contribution margin also subtracts the variable costs of selling each unit: outbound shipping, payment gateway fees, marketplace commissions and sales commissions. This is the margin that pays for rent and salaries, and it drives your break-even point.
• Net margin subtracts every expense of the business, including fixed overheads, interest and tax.

An online seller can show a 45% gross margin and still lose money after a 20% marketplace commission, 8% shipping, 2% payment fees and 10% returns.

Adding GST correctly

For a GST-registered business, the tax you collect is not income. Always:

1. Work out the price before GST from your cost and target margin
2. Add GST at the correct rate on that price
3. Use the price before GST when you measure margin

Example: cost ₹750 (input GST on the purchase is claimed as credit, so it is not part of cost), target margin 25%, GST 18%. Price before GST ₹1,000, GST ₹180, invoice ₹1,180. If you had calculated the margin on ₹1,180, you would believe you earned 36% and under-price the next product. The GST calculator helps when a customer asks for an inclusive price.

If you are not registered, or the input tax is not creditable, the GST you paid on purchases is part of your cost.

Discounts eat margin faster than you think

A 10% discount on a product with a 30% margin removes a third of your profit:

To make the same total profit after the discount, you need to sell 50% more units. Keep this in mind before running a sale, and prefer bundles or free delivery thresholds, which often protect margin better.

Margin by channel

The same product can have very different margins depending on where it sells:

A business that grows only through the lowest-margin channel can double revenue and still see profit stall. Track margin by channel, and price each channel for its own costs.

Typical margins vary widely

Grocery and distribution businesses often run on thin margins with high volume. Branded consumer products, software and professional services can sustain much higher gross margins because their direct cost per unit is low. Rather than chasing an industry average, track your own margin by product, customer and channel, and act on the worst performers.

Worked example: a wholesale order

A stationery distributor buys A4 paper at ₹210 a ream, pays ₹6 a ream in freight inward and wants a 12% gross margin on trade sales, with 18% GST on the invoice.

1. Landed cost = 210 + 6 = ₹216
2. Price before GST = 216 ÷ (1 − 0.12) = ₹245.45
3. GST at 18% = ₹44.18
4. Invoice price = ₹289.63 per ream
5. Profit per ream = ₹29.45; markup on cost = 13.6%

If a buyer asks for a ₹10 discount on the pre-GST price, profit falls to ₹19.45 per ream, a cut of a third, which should be traded for a larger order or faster payment rather than given away.

Pricing checklist

• Know the full landed cost of each item, updated when supplier prices change
• Decide margin targets by category, not one number for everything
• Price before GST, then add tax
• Check the price against competitors and the value to the customer
• Review margins monthly, not at year end
• Send quotes that show price, tax and terms clearly, using a proper quotation format

Tracking margin automatically

Margins drift when purchase prices rise and selling prices do not. MizUp Finance records purchase costs, stock and sales together, so item-wise and customer-wise profit is a report you can open any day, and your GST invoices are calculated correctly from the same data.
