Profit Margin Calculator

Calculate your exact profit margin percentage from any product cost and selling price. Our business profit calculator shows both gross margin and markup, helping you understand your true profitability. Perfect for retail stores, ecommerce, and wholesale businesses.

Understand the crucial difference between markup and margin. A 50% markup does NOT equal 50% margin — it equals 33.3% margin. Our markup vs margin calculator converts between them and shows why this distinction matters for pricing and profitability analysis.

Calculate both gross profit margin (revenue minus COGS) and understand net profit margin (after all expenses). Our gross profit margin calculator helps you analyze product-level profitability, while net margin shows overall business health.

Find the right selling price to achieve your target profit margin. Enter your cost and desired margin percentage, and our pricing margin calculator shows exactly what price to charge. Essential for competitive pricing strategy.

Profit margin is your profit expressed as a percentage of selling price, calculated as ((Selling Price − Cost) ÷ Selling Price) × 100. If a product sells for $100 and costs $60, your $40 profit divided by the $100 price gives a 40% margin.

The key distinction is what sits in the denominator. Margin divides profit by revenue, while markup divides the same profit by cost, which is why the two percentages never match.

Businesses generally track three layers of margin:

• Gross profit margin — revenue minus cost of goods sold, before operating costs
• Operating margin — after wages, rent, and overhead
• Net profit margin — after all expenses, interest, and taxes

The U.S. Securities and Exchange Commission (SEC) requires public companies to report these figures in their income statements, making margin a standardized measure of profitability.

Start by choosing what you want to solve for, then enter the two values you already know. The calculator returns margin, markup, and profit amount together so you can compare pricing scenarios instantly.

Worked example — you buy inventory for $45 and plan to sell it for $75:

• Enter $45 as the cost and $75 as the selling price
• Profit = $75 − $45 = $30
• Margin = ($30 ÷ $75) × 100 = 40%
• Markup = ($30 ÷ $45) × 100 = 66.67%

To work backward instead, switch the mode to price-from-margin: enter a $45 cost and a 40% target, and the tool returns the $75 price using Price = Cost ÷ (1 − Margin).

The U.S. Small Business Administration (SBA) recommends running these pricing scenarios before launch so every unit covers its true landed cost.

The most common mistake is confusing markup with margin, which causes chronic underpricing. Applying a 40% markup when you meant a 40% margin leaves you with only about 29% margin and a shortfall on every sale.

Watch for these frequent errors:

• Confusing markup and margin — margin uses price as the base, markup uses cost
• Ignoring hidden costs — payment processing, shipping, returns, and platform fees all erode real margin
• Using gross margin as take-home profit — gross margin excludes payroll, rent, and taxes
• Forgetting income tax — the Internal Revenue Service (IRS) taxes net business profit, not gross margin
• Not updating for cost inflation — supplier prices tracked by the U.S. Bureau of Labor Statistics (BLS) Producer Price Index can shift your margin without a price change

Recalculate margins whenever costs move, and always base take-home estimates on net rather than gross figures.

A "good" profit margin depends heavily on your industry, because cost structures and turnover rates differ widely. High-volume sectors like grocery survive on thin margins, while specialty and service businesses target much higher percentages.

As a general guide, typical gross margin ranges look like this:

• Grocery and food retail — often the lowest, driven by volume
• Apparel and general retail — moderate, with room for markdowns
• Electronics — usually compressed by competition
• Software and digital products — among the highest, with minimal unit cost

Net margins are always lower than gross because they absorb overhead and taxes. Rather than chasing a universal number, compare against your own sector: the U.S. Securities and Exchange Commission (SEC) publishes public-company filings, and the U.S. Small Business Administration (SBA) offers industry benchmarking resources you can measure your results against.

Markup and margin describe the same profit from two different bases, so converting between them is a fixed formula, not an estimate. Use Margin = Markup ÷ (1 + Markup) to go one way, and Markup = Margin ÷ (1 − Margin) to reverse it.

Quick reference points that are always true:

• 25% margin = 33.3% markup
• 33.3% margin = 50% markup
• 50% margin = 100% markup
• Markup is always the larger of the two numbers

For example, a 50% markup on a $60 cost yields a $90 price and a $30 profit, which is only a 33.3% margin — a gap that surprises many new sellers.

This relationship never changes, unlike tax rates the Internal Revenue Service (IRS) revises annually, so you can rely on it permanently when translating supplier quotes into shelf prices.

You can widen margin by cutting the cost side of the equation rather than raising prices, which protects sales volume while improving profitability per unit. Since margin = (Price − Cost) ÷ Price, lowering cost lifts the percentage directly.

Practical levers that expand margin include:

• Negotiating supplier terms or buying at higher volume for unit discounts
• Reducing shrinkage and returns, which quietly drain realized margin
• Trimming payment and platform fees by steering customers to lower-cost channels
• Bundling to raise average order value without discounting
• Improving inventory turnover so capital is not tied up in slow stock

Monitor input-cost trends through the U.S. Bureau of Labor Statistics (BLS) Producer Price Index, and remember that the Internal Revenue Service (IRS) lets you deduct legitimate business expenses, so accurate cost tracking both sharpens margin and lowers taxable profit.

Use gross margin for pricing individual products and net margin to judge overall business health. Each margin answers a different question, so applying the wrong one leads to poor decisions.

Here is what each measure captures:

• Gross margin — revenue minus cost of goods sold; best for setting and comparing product prices
• Operating margin — after wages, rent, and marketing; shows how efficiently core operations run
• Net margin — after interest and taxes; reflects true bottom-line profit the owner keeps

A business can post a strong gross margin yet a weak net margin if overhead is bloated, which is why the U.S. Securities and Exchange Commission (SEC) requires all three on public income statements.

For tax planning, the figure that matters is net profit, since the Internal Revenue Service (IRS) assesses business income tax on net earnings rather than gross margin.
