Difference between profit margin and markup
Margin and markup are often confused, but they measure profit from two different bases. Margin measures profit as a percentage of selling price. Markup measures profit as a percentage of cost. Those two percentages are not interchangeable, and treating them as if they were the same often leads to underpricing.
The core formulas
Gross Profit = Selling Price โ Cost
Gross Margin % = (Selling Price โ Cost) รท Selling Price ร 100
Markup % = (Selling Price โ Cost) รท Cost ร 100
Target Price from Margin = Cost รท (1 โ Target Margin)
Margin is based on price. Markup is based on cost. That is why a 50% markup does not equal a 50% margin.
How to choose a selling price
A profitable price has to do more than cover direct cost. It also needs to leave room for overhead, discounts, channel commissions, mistakes, returns, and growth. A price that looks profitable at the gross level can still underperform badly once operating expenses are included.
That is why this tool includes both per-unit and batch profitability views.

What It Answers |
| Gross margin | Pricing quality | How much of the selling price remains after direct cost |
| Markup | Cost-based pricing | How much profit is added above cost |
| Net profit | Business reality | What remains after expenses |
| Target price | Pricing design | What price is needed to hit a chosen margin |
Why discounts can hurt profit faster than expected
A discount cuts price directly, but cost usually does not fall with it. That means even a modest discount can erase a large share of gross profit. The lower the original margin, the more dangerous discounting becomes.
This is why businesses often feel strong top-line sales during promotions while still seeing weak bottom-line results.
Frequently Asked Questions
What is a good profit margin?+
That depends on the industry, business model, return rates, and operating complexity. A good margin is one that leaves enough room for fixed costs, risk, growth, and pricing pressure while still producing attractive net profit. Use the result as a business performance estimate, not as accounting advice. Real margins and returns can change when refunds, discounts, taxes, shipping, payment fees, labour, rent, inventory write-offs, and overhead allocation are included. The calculator is best used to compare scenarios and understand the relationship between revenue, cost, and profit.
What is the difference between margin and markup?+
Margin is profit divided by selling price. Markup is profit divided by cost. They describe the same profit from different starting points, so the percentages are different. Use the result as a business performance estimate, not as accounting advice. Real margins and returns can change when refunds, discounts, taxes, shipping, payment fees, labour, rent, inventory write-offs, and overhead allocation are included. The calculator is best used to compare scenarios and understand the relationship between revenue, cost, and profit.
Can I have positive markup and low margin?+
Yes. That is common. A product can have a decent markup on cost and still produce a relatively low margin once measured against the selling price. Use the result as a business performance estimate, not as accounting advice. Real margins and returns can change when refunds, discounts, taxes, shipping, payment fees, labour, rent, inventory write-offs, and overhead allocation are included. The calculator is best used to compare scenarios and understand the relationship between revenue, cost, and profit.
Why does discounting reduce profit so much?+
Because the discount cuts price immediately while cost often stays the same. Profit is the narrow gap between price and cost, so reducing price compresses that gap very quickly. Use the result as a business performance estimate, not as accounting advice. Real margins and returns can change when refunds, discounts, taxes, shipping, payment fees, labour, rent, inventory write-offs, and overhead allocation are included. The calculator is best used to compare scenarios and understand the relationship between revenue, cost, and profit.
How do I calculate target price from desired margin?+
Divide cost by one minus the desired margin as a decimal. For example, a cost of 40 and a desired margin of 35% requires a price of 40 รท 0.65 = 61.54. Use the result as a business performance estimate, not as accounting advice. Real margins and returns can change when refunds, discounts, taxes, shipping, payment fees, labour, rent, inventory write-offs, and overhead allocation are included. The calculator is best used to compare scenarios and understand the relationship between revenue, cost, and profit.
