Markup Calculator

This free markup calculator turns your product cost into a profitable selling price. Enter your cost and markup percentage to see the price, gross profit and profit margin instantly — or enter cost and price to work backward to your markup.

How to Use the Markup Calculator

Pricing a product comes down to three numbers — your cost, your markup, and your selling price — and you only need two of them. Start by entering your true product cost: not just the wholesale price, but the landed cost including freight, packaging, marketplace fees and anything else you pay per unit. That honest cost figure is where most pricing mistakes begin; people price off the sticker price of the goods and quietly lose money on everything around them.

Then pick one of two paths. Path one: enter a markup percentage and the calculator instantly gives you the selling price, the gross profit per unit and the profit margin. Path two: enter a selling price instead — the one the market will bear, or the one a competitor charges — and the tool works backward to reveal the markup %, gross profit and margin you would earn at that price. Results update live as you type, so you can nudge the markup up or down and watch the price move in real time until the numbers fit your strategy.

Markup Formula: How It Works

Markup is profit expressed as a percentage of cost. If an item costs you $12 and you sell it for $18, the $6 profit is 50% of the $12 cost — that is a 50% markup. The forward formula, cost to price, multiplies the cost by one plus the markup as a decimal:

Working backward from a price uses the inverse: markup % = (price − cost) ÷ cost × 100. And the closely related profit margin — profit as a percentage of the selling price — is margin % = (price − cost) ÷ price × 100. Because margin divides by the larger price instead of the smaller cost, margin is always a lower number than the equivalent markup, a distinction that trips up even experienced sellers.

Worked Example

You make candles. Each candle costs you $12.00 all-in (wax, jar, wick, label, packaging), and you decide on a 50% markup:

Now run it backward. A competitor sells a similar candle for $24 and your cost is still $12: markup = ($24 − $12) ÷ $12 × 100 = 100%, and margin = $12 ÷ $24 × 100 = 50%. That pair of numbers — 100% markup, 50% margin — is the classic "keystone" pricing used across retail, and it shows the relationship cleanly: at 100% markup the price is double the cost, so exactly half of it is profit.

Markup vs. Margin: The #1 Pricing Mistake

Ask ten small-business owners for a "40% profit" and half will price with 40% markup while the other half expects a 40% margin — and those produce different prices. A 40% markup on a $50 cost gives $70, which is only a 28.6% margin. If your business plan assumed 40% margin, you just gave away over $14 of expected profit per unit. Here is the conversion table that settles it:

The quick conversions: margin = markup ÷ (100 + markup) × 100 and markup = margin ÷ (100 − margin) × 100. Before you set prices, decide which number your targets use — most accounting and investor discussions run on margin, while day-to-day retail pricing runs on markup. Mixing them up is how profitable-looking businesses quietly underprice.

Limitations

This calculator works with gross figures: revenue minus the direct cost you entered. It does not account for overhead — rent, salaries, payment-processing fees, returns, or spoilage — so the "profit" shown is gross profit per unit, not net profit. Real pricing needs those fixed costs spread across expected volume, which is why a 50% markup can still lose money at low sales volumes.

The tool also assumes one flat markup for every unit. It does not model volume discounts, tiered wholesale pricing, promotional markdowns, or the sales tax that gets added at checkout in most US states. Use it to set and sanity-check prices, not as a substitute for a full profit-and-loss review with your accountant. This is an estimate for guidance, not financial advice.
