Profit Margin Calculator: Markup vs Margin and the Math Behind Pricing
Confusing markup with margin is one of the most common pricing mistakes — 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 — the formulas
**Markup** = (Price − Cost) ÷ Cost × 100. **Margin** = (Price − Cost) ÷ Price × 100. They convert as: margin = markup ÷ (1 + markup), and markup = margin ÷ (1 − margin).
A 100% markup is a 50% margin. A 50% markup is a 33% margin. The difference grows quickly at higher percentages — a 200% markup is only 67% margin.
Markup-to-margin conversion table
| Markup | Margin | Same as saying |
|---|---|---|
| 10% | 9.1% | Cost ×1.10 = Price |
| 25% | 20.0% | Cost ×1.25 = Price |
| 33% | 25.0% | Cost ×1.33 = Price |
| 50% | 33.3% | Cost ×1.50 = Price |
| 75% | 42.9% | Cost ×1.75 = Price |
| 100% | 50.0% | Cost ×2.00 = Price (double) |
| 150% | 60.0% | Cost ×2.50 = Price |
| 200% | 66.7% | Cost ×3.00 = 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 — interest, tax, the works. The bottom line.
- Contribution margin
- Revenue minus variable costs only (not including fixed costs). Used for break-even analysis.
Healthy margin ranges by industry
- •Software (SaaS): 70–90% gross margin. Code copies cost almost nothing.
- •Restaurants: 60–70% gross margin on food, but operating margin only 3–6% after labor and rent.
- •Retail: 30–50% gross margin typical; grocery 1–3% net margin.
- •Consulting: 50–70% margin if billing time directly; lower if reselling labor through agencies.
- •Manufacturing: 20–40% gross margin depending on commodity vs branded products.
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.
