Pricing is the lever most small businesses struggle with, and the confusion almost always comes from mixing up two words that sound identical but are not: markup and margin. This markup calculator takes your cost, your selling price, and (optionally) the quantity you plan to move, and returns both percentages side by side — plus the total batch revenue, batch cost, and batch profit for your volume — so you stop guessing whether a 50% markup means you are keeping half the price (you are not). Adjust the sliders and every figure updates instantly.
The single idea to hold onto is this: markup is measured against what the item cost you, while margin is measured against what the item sells for. Same profit dollars, two different denominators. Getting them backwards is the most common reason retailers think they are more profitable than they actually are.
How to Use
- Enter the Cost (Wholesale / COGS) — what the product cost you to source or make. Include the wholesale purchase price, materials, and any direct labor that went into one unit.
- Enter the Selling Price — the price on the tag, before tax.
- Enter the Quantity Sold you expect to move at this price. The default of 100 units is only a starting point; set it to your monthly run rate, a minimum order, or a forecast. Leave it at the default if you only care about the per-unit percentages.
- Read the result card. Markup is highlighted; Profit Margin and Gross Profit per Unit sit beside it.
- To hit a target, slide your selling price up or down and watch how markup grows faster than margin. A 100% markup, for example, only ever equals a 50% margin.
- Use the Price as Multiple of Cost line (the selling price divided by cost) as a quick rule of thumb for your category — a 1.5x multiple means you price at cost plus 50%.
- The batch totals — Total Batch Revenue, Total Batch Cost, and Total Batch Gross Profit — are what actually matter for covering rent and payroll. A 50% margin looks great until you multiply it by 50 units a month and see that the batch gross profit will not survive overhead.
If the cost field is zero or negative, the calculator flags an error rather than inventing a percentage, because dividing profit by a cost of zero has no meaningful answer.
The Markup vs Margin Formula
Both numbers start from the same profit:
- Gross Profit = Selling Price − Cost
- Markup = Gross Profit ÷ Cost × 100
- Profit Margin = Gross Profit ÷ Selling Price × 100
Once a quantity is entered, three batch totals drop out:
- Total Batch Revenue = Selling Price × Quantity
- Total Batch Cost = Cost × Quantity
- Total Batch Gross Profit = Gross Profit per Unit × Quantity
Worked example: an item costs $100 and you sell it for $150. Gross profit is $50. Markup = 50 ÷ 100 × 100 = 50%. Margin = 50 ÷ 150 × 100 = 33.3%. If you expect to sell 100 units, batch revenue is $15,000, batch cost is $10,000, and batch gross profit is $5,000. The profit is identical ($50 per unit), but markup tells you how much you added on top of cost, while margin tells you what share of the sale price you keep.
Why does this matter? Because investors, lenders, and tax advisors always talk about margin, while owners naturally think in markup. If you assume a 50% markup leaves you with 50 cents on every dollar, you have actually kept 33 cents — a gap big enough to sink a thin-margin business.
A quick conversion: markup is always larger than margin for the same sale. To turn a desired margin into the price you should charge, divide cost by (1 − desired margin). Want a 40% margin on a $60 cost? Price = 60 ÷ (1 − 0.40) = $100.
Examples
Example 1 — A boutique owner. A sweater wholesales for $40 and is ticketed at $70. Gross profit is $30. Markup = 30 ÷ 40 = 75%, while margin = 30 ÷ 70 = 42.9%. The owner brags about a "75% markup," but nearly 58 cents of every sale is not profit — it has to cover rent, payroll, and other overhead before any of it reaches the bottom line.
Example 2 — Hitting a target margin. A manufacturer needs a 50% margin on a part that costs them $25 to produce. Pricing at cost plus 50% ($37.50) is the trap: that is only a 33.3% margin. The correct price is 25 ÷ (1 − 0.50) = $50, which is a 100% markup — double the cost-plus number the owner first reached for.
Example 3 — Large-volume supplier. A distributor moves a pallet whose unit cost is $500,000 and sells it for $1,200,000. Gross profit is $700,000. Markup = 700,000 ÷ 500,000 = 140%, and margin = 700,000 ÷ 1,200,000 = 58.3%. Even on seven-figure deals the two percentages diverge, which is why the pricing sheet should always report margin — not markup — when investors are watching.
Example 4 — The break-even edge. If you sell an item for exactly what it cost, both markup and margin are 0%. There is gross profit to reinvest, and every fixed cost you sell at that price loses money on overhead. Sliding the selling price down to match cost on this calculator shows you exactly where the profitable pricing region begins.
FAQ
What is the difference between markup and margin?
Markup is profit divided by cost; margin is profit divided by selling price. On the same $50 profit from a $100 cost and $150 price, markup is 50% but margin is only 33.3%. Markup is always the larger of the two for a normal sale.
How do I calculate markup percentage?
Subtract your cost from the selling price to get gross profit, then divide that profit by the cost and multiply by 100: markup = (sellingPrice − cost) ÷ cost × 100. A $150 price on a $100 cost gives (150 − 100) ÷ 100 × 100 = 50% markup.
Why do retailers prefer markup and investors prefer margin?
Retailers think in terms of "how much do I add on top of what I paid," which is intuitive when you price item by item. Investors and lenders care about what fraction of each sale survives after the product itself is paid for, which is margin. Reporting margin keeps everyone aligned on the true economics.
If I want a 40% margin, what should my markup be?
A 40% margin corresponds to a markup of 40 ÷ (100 − 40) = 66.7%. The general rule: markup = margin ÷ (1 − margin). This is why pricing at "cost plus 40%" (a 40% markup) only delivers a 28.6% margin — most owners miss this gap.
Can markup be more than 100%?
Yes. Markup is not capped at 100%. If an item costs $10 and sells for $30, gross profit is $20 and markup is 200%. Margin on the same sale is only 66.7%. Luxury goods, software, and branded consumables routinely run markups well above 100% because their cost of goods is tiny relative to perceived value.
What happens when the cost is zero?
Markup divides profit by cost, so a zero cost has no finite markup — the calculator leaves markup undefined rather than returning infinity. Margin, however, is fully defined: if an item costs nothing and sells for $100, gross profit is $100 and margin is 100%. This is the economics of free samples, digital goods, and salvaged inventory.
Is this markup calculator the same as the profit margin calculator?
They are related but not interchangeable. A standalone profit-margin calculator starts from revenue and cost of goods sold for a whole period, while this page focuses on a single unit and deliberately contrasts markup against margin so you never confuse the two. Use this one when you are setting a price; use the margin one when you are reporting a period's results.
Why does the quantity field affect the batch totals but not the percentages?
Markup and margin are ratios per unit — they depend only on cost and selling price, not on how many units you move. The quantity field is what turns those per-unit ratios into the dollars that actually hit your bank account: batch revenue, batch cost, and batch gross profit. If you only need the percentage, leave quantity at the default; if you are deciding whether a product is worth carrying, plug in your forecast volume and read the batch gross profit against your monthly fixed costs.
