Margin vs. markup — the mix-up that costs money
This is the single most common pricing mistake: margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost. A 50% markup on a $10 item prices it at $15 — but that $5 profit is only a 33% margin on the $15 selling price, not 50%. Confusing the two leads to underpricing products, since a target margin always requires a larger markup percentage to hit it.
The four modes
- Profit mode — enter cost and revenue to see the gross profit amount.
- Margin mode — see profit as a percentage of revenue.
- Markup mode — see profit as a percentage of cost.
- Selling price mode — work backward from a cost and a target margin or markup to find the price you should charge.
Step-by-step
- Select the mode matching your question.
- Enter cost, revenue, or your target percentage, depending on the mode.
- Read the results, which update live as you adjust any input.

Frequently Asked Questions
What's the actual difference between margin and markup?
Margin is profit as a percentage of the selling price (revenue). Markup is profit as a percentage of the cost. The same dollar profit produces a smaller margin percentage than markup percentage.
How is ROI calculated?
ROI = (Net Profit / Cost) × 100.
If I want a 40% margin, is that the same as a 40% markup?
No — hitting a 40% margin requires a markup percentage higher than 40%, since margin is measured against the higher selling price, not the cost. Use Selling Price mode to work out the exact price needed for a target margin.
