What is the Profit Margin Calculator?

A profit-margin calculator shows what share of your revenue is profit, after costs — expressed as a percentage.

How the Profit Margin Calculator works

Profit = revenue − cost; gross margin = profit ÷ revenue × 100. Margin uses revenue as the base, which is different from markup, which uses cost as the base.

Gross margin % = (Revenue − Cost) ÷ Revenue × 100

Enter your revenue — the total money a business earns from sales before any costs are subtracted.
Enter your cost of goods sold (cogs) — the direct costs of producing what you sold - materials and direct labor.
Enter your margin — profit expressed as a percentage of revenue.
Enter your gross profit — revenue minus the direct cost of goods sold (COGS), before overheads.
Read the result, then change any input to compare scenarios instantly — the Profit Margin Calculator recalculates as you type.

Understanding the inputs

What each value means, why it matters, and a typical range — so you can fill in the calculator with confidence.

Revenue

The total money a business earns from sales before any costs are subtracted.

Why it matters:: It is the top line - every margin and profit figure starts from revenue.
Typical range:: Varies entirely by business size.

How it affects results:

Higher: More to cover costs and profit, if margins hold.
Lower: Less to cover costs and profit.

Common mistake: Confusing revenue (sales) with profit (what is left after costs).

Cost of Goods Sold (COGS)

The direct costs of producing what you sold - materials and direct labor.

Why it matters:: It is subtracted from revenue to get gross profit, the core of product economics.
Typical range:: Often 40% to 80% of revenue depending on the business.

How it affects results:

Higher: Lower gross margin.
Lower: Higher gross margin.

Common mistake: Including overheads like rent and admin, which are not direct costs.

Margin

Profit expressed as a percentage of revenue.

Why it matters:: A percentage lets you compare profitability across products and businesses of any size.
Typical range:: 10% to 20% net margin is healthy for many businesses; under 10% is thin.

How it affects results:

Higher: More buffer and pricing power.
Lower: Less buffer against costs and price pressure.

Common mistake: Confusing margin (profit / price) with markup (profit / cost).

Gross Profit

Revenue minus the direct cost of goods sold (COGS), before overheads.

Why it matters:: It shows how profitable the core product is, before running costs.
Typical range:: 20% to 60% of revenue depending on industry.

How it affects results:

Higher: Strong product economics that can absorb overhead and scale.
Lower: Thin product economics with little room for overhead.

Common mistake: Subtracting overheads here - those belong to net profit, not gross.

Component definitions

The parts that drive this result and what each one contributes.

Revenue — Total sales before costs.
Costs — What you subtract to get profit.
Profit — What remains — the margin numerator.

Benchmark reference

What counts as poor, average or excellent for this metric.

Net Margin

Poor	<0%
Below average	0-5%
Average	5-10%
Above average	10-20%
Excellent	20%+

Gross Margin

Poor	<10%
Below average	10-20%
Average	20-40%

Excellent	60%+

Source: General industry ranges · Updated June 2026

Typical values

Net Margin:: 5-20% (varies by industry)
Gross Margin:: 20-60% (industry-dependent)

Common interpretation errors

Confusing gross and net margin
Excluding overheads, tax or fees
Confusing gross with net margin
Leaving some direct costs out of COGS

What impacts results most

1.
Costs (High impact)Lower costs lift margin directly.
2.
Revenue / price (High impact)A higher price raises margin fast.

Key assumptions

Margin is measured on price, not cost
Includes only the costs you enter

What's a typical value?

Healthy margins vary widely by industry — software and services run high, retail and groceries run thin. Compare against peers in your sector, not a universal number.

Markup vs profit margin (and sell price on a $100 cost)

10%	9%	$110
25%	20%	$125
50%	33%	$150
75%	43%	$175
100%	50%	$200
200%	67%	$300

Worked example

Revenue $100, cost $60: Profit $40 → margin 40%. The same item carries a 66.7% markup (40 ÷ 60), which is why the two figures differ.

Common mistakes to avoid

Confusing margin (base = revenue) with markup (base = cost).
Using only the unit cost and ignoring overhead, shipping and fees.
Quoting gross margin as if it were net profit.

Compared to alternatives

Margin vs Markup

Margin is profit over price; markup is profit over cost - same profit, different denominator.

	Margin	Markup
Denominator	Selling price	Cost
Always	Lower number	Higher number
Used for	Profitability	Pricing from cost

Bottom line: Price from markup; report profitability as margin.
