Profit Margin Formula

The Profit Margin formula is a vital financial metric that reveals how much profit a business makes from its total revenue, indicating its overall efficiency and health.

3 variables. Published Mar 12, 2026. Updated Mar 27, 2026. By AI Biz Hub.

Formula

Profit Margin = Net Profit / Revenue x 100

Variables

Profit Margin

Net profit as a percentage of revenue, showing how many cents of each sales dollar become profit after all costs. The headline efficiency measure.

Net Profit

Net profit in currency units: revenue minus all costs (COGS, operating expenses, interest, taxes). The numerator.

Reve

Revenue

Total sales revenue for the period in currency units. The denominator; use net revenue after refunds and discounts for an honest figure.

Step by step

1

Set the baseline case with the real calculator inputs.

Mode = Calculate margin, Revenue = $100,000, Cost = $85,000
2

Decide which profit line you are measuring (gross, operating, or net) and use the matching cost set, since the three margins answer different questions.

Revenue 200,000 less all costs of 170,000 leaves a 30,000 net profit.
3

Apply the formula and read the first calculator outputs, not just the headline assumption.

The calculator lands with profit at $15,000 and gross margin percent at 15.0%.
4

Re-run at the gross, operating, and net levels together, since a healthy gross margin can still end in a thin net margin once overhead is counted.

A 65% gross margin can collapse to a 15% net margin after operating costs.

Worked example

Profit Margin sample case

Mode

Calculate margin

Revenue

$100,000

Cost

$85,000

The calculator uses a single cost input, so total costs of 85,000 go in one field. Profit = Revenue - Cost = 100,000 - 85,000 = $15,000, and gross margin percent = 15,000 / 100,000 x 100 = 15.0%.

The calculator lands with profit at $15,000 and gross margin percent at 15.0%.

Common variations

Scenario variants are useful because fixed assumptions rarely survive contact with real life unchanged.

Use Profit Margin Calculator to compare the baseline result with one stressed case before relying on a single answer.
