Formula

Profit margin formulas

Gross margin = (revenue - cost of goods) / revenue x 100; net margin = (revenue - cost of goods - expenses) / revenue x 100; markup = (revenue - cost of goods) / cost of goods x 100

Gross margin looks only at direct costs. Net margin also includes operating expenses.

How to use

Steps

  1. Enter total revenue for the sale, product, job, or period.
  2. Enter cost of goods or direct delivery cost.
  3. Add operating expenses if you want a net margin estimate.
  4. Use target net margin to estimate the revenue needed for that margin.

Calculator use

Best for

  • Use this profit margin calculator to compare revenue, cost of goods, operating expenses, gross profit, net profit, markup, break-even revenue, and revenue for target margin.
  • Estimating business pricing, margin, retention, runway, dilution, revenue, or profitability before an operating decision.
  • Comparing base, conservative, and optimistic assumptions with the revenue, cost, churn, or payment timing visible.
  • Preparing a planning number before updating books, forecasts, contracts, or investor materials.

Before relying on it

Check first

  • Mixing cash flow, accounting profit, bookings, revenue recognition, one-time fees, and recurring revenue.
  • Leaving out taxes, refunds, discounts, churn, payment delays, support cost, contractor cost, or owner time.
  • Using one optimistic case as the operating plan without checking downside assumptions.

Details

What to know before using the result

These notes make the assumptions explicit, especially where the same search query can mean slightly different things.

Gross vs netDifferent profit views

Gross margin only subtracts direct delivery costs. Net margin also subtracts operating expenses, so it is usually the better planning number.

Markup mismatchNot the same as margin

Markup is measured against cost, while margin is measured against selling price. A 50% markup is not a 50% margin.

Target margin revenueRevenue needed for the goal

Target margin revenue estimates how much revenue is needed to cover cost of goods, operating expenses, and still leave the selected net margin.

Break-even usePrice and volume together

A price can look profitable per unit but still miss break-even if fixed costs, refunds, discounts, or acquisition costs are ignored.

Next decisionMove from margin to cause

After checking profit margin, review break-even revenue, agency margin, client profitability, retainer pricing, and small-business cash flow before changing price or cost structure.

Benchmarks

How to read the result

The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.

Under 10%: Thin margin.

Small errors, refunds, fees, or discounts can wipe out profit quickly.

10% - 30%: Moderate margin.

Common planning range for many service and commerce scenarios after normal expenses.

30%+: Strong margin.

Often leaves more room for overhead, acquisition costs, discounts, or reinvestment.

Calculator accuracy

Methodology and assumptions

The formula, inputs, example, and limitations are shown so the result is checkable, not just a number in a box.

Formula

Gross margin = (revenue - cost of goods) / revenue x 100; net margin = (revenue - cost of goods - expenses) / revenue x 100; markup = (revenue - cost of goods) / cost of goods x 100

Inputs used

Revenue, Cost of goods, Operating expenses, Target net margin

Limitations

Business results depend on contracts, accounting treatment, taxes, payment timing, refunds, collections, and operating assumptions.

FAQ

Common questions

What is the difference between profit margin and markup?

Profit margin compares profit to selling price. Markup compares profit to cost. The same sale can have a 40% margin and a 66.7% markup.

How do I calculate net profit margin?

Subtract cost of goods and operating expenses from revenue, divide by revenue, then multiply by 100.

Should I use gross margin or net margin?

Use gross margin to understand direct product or delivery profitability. Use net margin when operating expenses matter to the decision.

How do I use target margin revenue?

Target margin revenue estimates the revenue needed to cover costs and still hit a chosen net margin. If the required revenue is unrealistic, review pricing, cost of goods, fixed costs, or scope.

Can this replace accounting or legal advice?

No. Business tools are scenario planners. Contracts, taxes, payment timing, accounting treatment, refunds, and legal requirements can change decisions.

What should I do after using a business tool?

Save the assumptions, compare a conservative scenario, and review the result with actual books, contracts, or an advisor before making a high-stakes decision.
