Profit Margin Calculator: Markup vs Margin and the Math Behind Pricing
Confusing markup with margin is one of the most common pricing mistakes β and it can quietly wreck the unit economics of a business. This calculator handles both, plus the related calculations of break-even price and selling price from a target margin.
Margin and markup describe the same gap between cost and price, but they're calculated against different bases. **Markup** is profit divided by cost (50 markup on cost of 100 = 50% markup). **Margin** is profit divided by selling price (50 profit on price of 150 = 33% margin). The same dollar profit looks like different percentages depending on which framing you use.
Vendors and salespeople often quote markup (which sounds bigger); accountants and investors quote margin (which is what shows up on the income statement). Mixing them up can cause real money to leak out of a business.
Markup vs margin β the formulas
**Markup** = (Price β Cost) Γ· Cost Γ 100. **Margin** = (Price β Cost) Γ· Price Γ 100. They convert as: margin = markup Γ· (1 + markup), and markup = margin Γ· (1 β margin).
A 100% markup is a 50% margin. A 50% markup is a 33% margin. The difference grows quickly at higher percentages β a 200% markup is only 67% margin.

| Markup | Margin | Same as saying |
|---|---|---|
| 10% | 9.1% | Cost Γ1.10 = Price |

| 75% | 42.9% | Cost Γ1.75 = Price |
| 100% | 50.0% | Cost Γ2.00 = Price (double) |
| 150% | 60.0% | Cost Γ2.50 = Price |
| 200% | 66.7% | Cost Γ3.00 = Price (triple) |
Common margin types
- Gross margin
- Revenue minus direct cost of goods, divided by revenue. The fundamental unit-economics metric.
- Operating margin
- Gross margin minus operating expenses (rent, salaries, marketing). What's left before interest and tax.
- Net margin
- What's actually kept after everything β interest, tax, the works. The bottom line.
- Contribution margin
- Revenue minus variable costs only (not including fixed costs). Used for break-even analysis.

Extended FAQ
Why does the same product show different margins year-to-year?
Cost can shift (raw materials, labor) even when price doesn't. A 5% cost increase on a 30%-margin product becomes a 7% margin hit if you can't pass it through to price.
Should I use markup or margin to compare against competitors?
Margin. It's the standard metric for income-statement reporting and benchmarking. If a vendor only quotes markup, convert to margin before comparing.
Does margin include taxes?
Gross margin doesn't (tax is below gross profit). Net margin does. Always state which one you mean.
