What Is Profit Margin?
Profit margin measures how much of every dollar in revenue a business keeps as profit. Higher margins mean more efficient profitability.
There are three key margin levels, each deducting progressively more costs:
- Gross Profit Margin: Revenue minus cost of goods sold (COGS), as a percentage of revenue
- Operating Profit Margin: Gross profit minus operating expenses (salaries, rent, marketing)
- Net Profit Margin: Bottom-line profit after all costs including taxes and interest
The Formulas
Gross Margin = (Revenue − COGS) ÷ Revenue × 100%
Net Margin = Net Profit ÷ Revenue × 100%
Markup = Profit ÷ Cost × 100% (different from margin — see below)
Worked Example
Product selling price: $50. Cost to produce: $30.
- Gross profit = $50 − $30 = $20
- Gross margin = $20 ÷ $50 × 100% = 40%
- Markup = $20 ÷ $30 × 100% = 66.7%

| Grocery retail | 20%–30% | 1%–3% |
Margin vs Markup: A Common Confusion
These two are frequently confused — and the difference matters for pricing:
- Margin: Profit as a percentage of selling price
- Markup: Profit as a percentage of cost
A 40% markup and a 40% margin are very different things:
- Cost $60 + 40% markup → Price $84 → Margin = $24/$84 = 28.6%
- Cost $60 with 40% margin target → Price $100 → Markup = $40/$60 = 66.7%
Frequently Asked Questions
What is a good profit margin?
It depends entirely on the industry. SaaS companies routinely see 70%+ gross margins; grocery stores at 25% are healthy. The right benchmark is your industry average and whether margins are trending up.
How do I improve my profit margin?
Two levers: raise prices (requires product differentiation to justify) or reduce costs (COGS, operating expenses). The most effective approach combines both: increase perceived value while systematically reducing cost structure.
