How it works: Margin and markup are different ways to measure profitability. Margin = (Selling Price - Cost) / Selling Price × 100%. Markup = (Selling Price - Cost) / Cost × 100%. Margin shows profit as a percentage of selling price, while markup shows profit as a percentage of cost. A 50% markup equals a 33.3% margin. Use margin for pricing decisions and markup for cost-based pricing.
What Is a Margin Calculator?
A margin calculator finds your gross profit margin — the percentage of revenue left after deducting the cost of goods sold (COGS). It also calculates markup (profit as a percentage of cost) and can solve for cost, selling price, or profit given any two of the three values. These are the core metrics for pricing decisions in retail, e-commerce, manufacturing, and freelance services.
The key distinction: margin uses selling price as the denominator; markup uses cost. Confusing them is one of the most common pricing errors in small business.
How to Use This Margin Calculator
- Enter the cost (what you pay to produce or acquire the item).
- Enter the selling price (what you charge the customer).
- The calculator returns profit, gross margin %, and markup %.
- Or enter cost + target margin to find the required selling price.
Worked Example: Margin vs. Markup on a $50 Cost Item
Cost: $50.00 | Selling price: $80.00
| Metric | Formula | Result |
|---|---|---|
| Profit | $80 − $50 | $30.00 |
| Gross Margin | $30 ÷ $80 × 100 | 37.5% |
| Markup | $30 ÷ $50 × 100 | 60% |
The same $30 profit is expressed as 37.5% margin (relative to revenue) or 60% markup (relative to cost). Both are correct — they answer different questions.

Gross Margin vs. Net Margin vs. Operating Margin
- Gross margin: (Revenue − COGS) ÷ Revenue. Covers only direct production costs. This is what this calculator computes.
- Operating margin: (Revenue − COGS − Operating expenses) ÷ Revenue. Adds overhead, salaries, rent.
- Net margin: Net income ÷ Revenue. The bottom line after tax and interest. Typically 3–10% for most industries.
Tips for Setting Profitable Margins
- Know your industry benchmarks: Grocery margins run 2–5%; software SaaS margins can exceed 70%. Compare to peers before setting targets.
- Price to target margin, not just markup: Retailers often think in markup but lenders and investors evaluate margin. Know both.
- Account for all costs in COGS: Missing shipping, packaging, or payment processing fees inflates your apparent margin.
- Factor in returns and shrinkage: If 5% of units are returned, your effective margin is lower than the per-unit calculation suggests.
Frequently Asked Questions About Profit Margin
What is a good profit margin?
It varies by industry. Retail: 2–5%. Restaurants: 3–9%. Software: 60–80%. Professional services: 15–40%. Compare to industry averages rather than a single benchmark.
How do I convert markup to margin?
Margin = Markup ÷ (1 + Markup). Example: 60% markup → 0.60 ÷ 1.60 = 37.5% margin. Reverse: Markup = Margin ÷ (1 − Margin). 37.5% margin → 0.375 ÷ 0.625 = 60% markup.
What selling price gives me a 40% margin on a $30 cost?
Selling price = Cost ÷ (1 − margin) = $30 ÷ 0.60 = $50.00. Profit = $20, which is 40% of $50.
Why is margin always lower than markup for the same profit?
Because margin uses the larger selling price as denominator while markup uses the smaller cost. The same $30 profit on a $50 cost item is 37.5% of the $80 selling price but 60% of the $50 cost.
