Margin Calculator

Confused about the difference between margin and markup? This calculator handles both — and lets you find selling price, cost, or margin percentage given any two of those three values.

Margin vs. Markup: The Key Difference

• Profit margin: Profit as a percentage of the selling price. A 30% margin means 30 cents of every dollar you collect is profit.
• Markup: Profit as a percentage of the cost. A 30% markup means you added 30 cents for every dollar it cost you.

The same product priced at 30% margin has a different markup than a product priced at 30% markup — they are NOT interchangeable.

How to Use This Calculator

1. Enter any two of the three values: Cost, Selling Price, or Profit Margin %.
2. Click Calculate to find the third, plus the equivalent markup percentage.

Key Formulas

Gross Profit = Revenue − COGS

Gross Margin % = Gross Profit ÷ Revenue × 100

Markup % = Gross Profit ÷ Cost × 100

Selling Price (from margin) = Cost ÷ (1 − Margin%)

Selling Price (from markup) = Cost × (1 + Markup%)

Example Calculation

Cost: $40 | Target margin: 35%

• Selling price: $40 ÷ (1 − 0.35) = $61.54
• Gross profit: $61.54 − $40 = $21.54
• Equivalent markup: $21.54 ÷ $40 × 100 = 53.8%

Margin Benchmarks by Industry

• Grocery retail: 2%–5% gross margin (high volume, low margin)
• Clothing/apparel: 40%–60%
• Software (SaaS): 70%–90%
• Restaurants: 3%–9% net margin (higher gross, high overhead)
• Manufacturing: 20%–40%

Common Mistakes to Avoid

• Using markup % as margin % — A 50% markup ≠ 50% margin. A 50% markup = 33.3% margin. Mixing these up leads to underpricing.
• Forgetting overhead costs — Gross margin covers cost of goods. Net margin subtracts operating expenses, interest, and taxes. Both matter for profitability analysis.
• Not updating margins when costs change — If supplier costs rise 10%, your margin shrinks unless you raise prices. Review margins quarterly.

Frequently Asked Questions

What is a good profit margin?

It depends heavily on industry. In general: net margin under 5% is thin, 10%–20% is healthy, and above 20% is excellent. Compare to industry averages, not arbitrary benchmarks.

How do I increase my profit margin?

Three levers: raise prices (most impactful), reduce COGS (better suppliers, less waste), or reduce overhead (operating expenses). Often a combination of all three is most effective.

What is the relationship between margin and markup?

Markup = Margin ÷ (1 − Margin) | Margin = Markup ÷ (1 + Markup). A 50% markup gives 33.3% margin. A 50% margin requires 100% markup (doubling your cost).

Conclusion

Pricing correctly requires understanding both margin and markup — and never confusing them. Use this calculator to set prices that hit your target margin and understand the equivalent markup percentage.
