Markup Calculator

How this markup calculator works

Pick whichever direction matches what you already know. If you know your cost and want to set a price using a target markup percentage, use "I know the markup %" — enter your cost and markup, and the calculator gives you the resulting selling price, profit per unit, and (importantly) the margin percentage that markup actually produces. If instead you already have both your cost and your selling price and want to know the markup and margin those numbers imply, switch to "I know the selling price". Either way, both markup and margin are shown together, because keeping them next to each other is the best way to avoid the single most common pricing mistake in retail: treating them as interchangeable.

Markup vs. margin — the difference that actually matters

Markup and margin both measure profitability, but they divide the same profit figure by two different numbers, and that difference matters a lot in practice. Markup = profit ÷ cost — it tells you how much you added on top of what you paid. Margin = profit ÷ selling price — it tells you what share of the money that changes hands at the register is actually profit. Because the selling price is always larger than the cost (assuming you're making money), dividing the same profit by the bigger number — price — always produces a smaller percentage than dividing it by the smaller number — cost. That means markup% is always higher than margin% whenever there's any profit at all, and the gap widens as the profit percentage grows.

The exact formulas

Starting from cost and a markup percentage: selling price = cost × (1 + markup% ÷ 100), profit = price − cost, and margin% = profit ÷ price × 100. Starting from cost and a known selling price instead: profit = price − cost, markup% = profit ÷ cost × 100, and margin% = profit ÷ price × 100. The relationship connecting the two, when expressed as decimals, is margin = markup ÷ (1 + markup), and the reverse is markup = margin ÷ (1 − margin) — useful if you ever need to convert a target margin directly into the markup percentage that will produce it.

A worked example

Say your cost is $50 per unit and you apply a 60% markup. Selling price = $50 × 1.60 = $80.00. Profit per unit = $80.00 − $50.00 = $30.00. Margin = $30.00 ÷ $80.00 × 100 = 37.5%. Notice the same $30 profit reads as a 60% markup against cost but only a 37.5% margin against price — same dollars, two very different-looking percentages, both correct for what they measure. Run it the other direction and you get identical numbers: cost $50, price $80 gives profit $30, markup 60% ($30÷$50), and margin 37.5% ($30÷$80) — confirming the two calculation directions are consistent.

Why this confusion costs real money

This isn't an academic distinction — retailers and small manufacturers routinely underprice their products by mixing up the two terms. If a business wants a 50% margin (a common target, since it means half of every sale is gross profit) and mistakenly applies a 50% markup instead, the actual margin achieved is only 33.3%, not 50% — a meaningful shortfall multiplied across every unit sold, every day, for as long as the mistake goes unnoticed. Wholesale and supplier price sheets often quote markup, while a company's own financial targets and reporting are usually expressed in margin, so the translation between the two happens constantly in day-to-day pricing decisions, purchasing negotiations, and margin-target conversations with a finance team.

Markup Calculator vs. Profit Margin Calculator — which to use

This page is built for the direction most retailers actually work in day to day: you know your cost, you decide on (or are told) a markup percentage, and you need the resulting selling price and what margin that markup actually delivers. For the reverse situation — you know your cost and selling price and want profit, margin and markup all at once, or you want to solve for the price needed to hit a specific target margin — the Profit Margin Calculator is built exactly for that. Both tools report markup and margin together so you're never left guessing which percentage you're looking at, and both are useful companions to the Inventory Turnover Calculator and the Amazon FBA Calculator when you're working through the full economics of a product line.

A quick reference: converting between markup and margin

Because the two percentages come up constantly in different contexts — supplier quotes in markup, financial statements in margin — it helps to have the conversion formulas on hand rather than re-deriving them each time. To go from a known markup to the margin it produces: margin = markup ÷ (1 + markup) (decimals). To go from a target margin to the markup needed to hit it: markup = margin ÷ (1 − margin) (decimals). A few reference points worth memorizing: a 25% markup produces a 20% margin; a 33.3% markup produces a 25% margin; a 100% markup ("keystone" pricing, common in retail) produces exactly a 50% margin; and a 300% markup produces a 75% margin. Notice how the gap between the two percentages widens as they get larger — at low markup levels the two numbers are close together, but they diverge sharply once markup climbs past 50–100%.

Where markup percentages come from in practice

Wholesalers, distributors and manufacturers frequently quote suggested or standard markups by product category — apparel, jewelry and restaurants have historically leaned on very high traditional markups (multiples of cost) to cover high spoilage, seasonal markdown risk, labor-intensive service, or slow turnover, while categories like electronics or groceries often run on much thinner markups because they turn over fast and compete heavily on price. When you're handed a supplier's suggested markup, running it through this calculator alongside your other fixed and variable costs (rent, labor, shipping, payment processing) is a useful sanity check — a markup that looks generous on paper can still leave a thin or negative true margin once every real cost is accounted for, which is exactly the gap this tool is built to surface before a price goes live.
