What it calculates

Profit Margin Calculator uses revenue, cost of goods, operating expenses, and target net margin to estimate gross margin, net margin, markup, break-even revenue, gross profit, net profit, and revenue for target margin.

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

  • Separating gross margin from net margin before evaluating a product, service line, or operating period.
  • Checking how cost of goods and operating expenses affect profit even when revenue stays unchanged.
  • Estimating the revenue required to reach a target net margin under the current cost structure.
  • Comparing pricing or cost-reduction scenarios without confusing margin percentage with markup percentage.

Before relying on it

Check first

  • Using margin and markup as interchangeable percentages even though they use different denominators.
  • Leaving operating expenses out of a net-margin calculation or adding them twice after they are already included elsewhere.
  • Treating revenue required for a target margin as a sales forecast without checking volume, capacity, taxes, and demand.
  • Comparing businesses or periods that classify cost of goods, owner compensation, refunds, and one-time expenses differently.

Details

What to know before using the result

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.

How to read the result

Under 10%: Thin margin.

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

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.

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.
