Difference between markup and margin
Markup and margin are often treated as if they are interchangeable, but they are not. Markup is measured against cost. Margin is measured against selling price. That means the same product can show a 50% markup and only a 33.33% margin at the same time.
This distinction matters because many pricing mistakes happen when a business targets one number but accidentally interprets it as the other.
The conversion formulas
Margin % = Markup % รท (100 + Markup %) ร 100
Markup % = Margin % รท (100 โ Margin %) ร 100
Selling Price from Markup = Cost ร (1 + Markup)
Selling Price from Margin = Cost รท (1 โ Margin)
Markup and margin are linked mathematically, but they use different denominators. That is why the percentages never match directly.
How to choose the right pricing method
Cost-based businesses often think in markup because the starting point is the cost base. Commercial finance teams often prefer margin because it reflects how much of revenue remains after direct cost. Both are useful, but they answer different questions.
If you are pricing for revenue quality, margin is usually the stronger operational control. If you are marking up inventory from purchase cost, markup can still be practical.

Frequently Asked Questions
What is the difference between markup and margin?+
Markup measures profit as a percentage of cost. Margin measures profit as a percentage of selling price. They describe the same gross profit from two different bases. 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 is a 50% markup not a 50% margin?+
Because a 50% markup means price is cost plus 50% of cost. That produces a selling price where gross profit is only one-third of the price, which equals a 33.33% margin. 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.
Which metric should I use for pricing?+
Use markup if your operational process starts from cost and adds a spread. Use margin if you want to manage how much of selling price remains after direct cost, which is usually stronger for commercial reporting and strategic pricing. 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 convert margin to markup exactly?+
Yes. The conversion is exact as long as the margin is below 100%. This calculator uses the correct denominator shift so the conversion is accurate. 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 did a small discount crush my margin?+
Because margin is based on price. When price falls and cost does not, the profit portion collapses quickly. Low-margin products are especially vulnerable to even small discounts. 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.
