Markup Calculator

Markup is the percentage you add to your cost to arrive at a selling price. Margin is the percentage of the selling price you keep as gross profit. They are computed from exactly the same two numbers, cost and price, yet they almost never produce the same figure, and mixing them up is the single most expensive arithmetic mistake in small retail, hospitality and e-commerce. A 50% markup is a 33.33% margin. A 100% markup (the classic "keystone" double-the-cost rule) is only a 50% margin. A shop owner who believes she is running a 50% margin when she is actually running a 50% markup is over-estimating gross profit on every single unit she sells.

This calculator prices from either direction. Enter a unit cost and a markup percentage and it returns the selling price, the profit per unit, and the equivalent margin. Or switch to margin mode, enter the margin you need to hit, and it returns the required price and the equivalent markup. It also shows a break-even table across a range of candidate prices, the number of units you must sell to cover your fixed costs at each one, plus common markup presets (10%, 20%, 30%, 50%, 100%) and industry presets for keystone retail, restaurants, bars, wholesale and SaaS. A VAT/GST field converts the net selling price into a tax-inclusive shelf price without contaminating the margin maths.

The one-line rule: markup uses cost as the denominator, margin uses price. Because cost is always smaller than price on a profitable sale, markup is always the bigger number.

How to Use

1. Unit cost, enter what one unit costs you to buy or produce. For a retailer this is the landed wholesale cost (invoice price plus freight and duty). For a restaurant it is the plate food cost. For a manufacturer it is direct materials plus direct labour.
2. Currency, pick a symbol ($, £, €, A$, C$, ₹). This is cosmetic; the maths is currency-agnostic.
3. Pricing mode, choose Markup % (on cost) if you work from a cost-plus rule ("we double everything"), or Margin % (of price) if your target comes from a P&L or a franchise agreement ("we need 65% gross margin").
4. Markup % or Margin %, enter the percentage. Margin must stay below 100% (a 100% margin would require zero cost).
5. Fixed costs, total period overheads (rent, salaries, insurance, software). Used only for the break-even columns; leave at 0 if you only want unit economics.
6. VAT / GST / sales tax %, enter your rate to see the tax-inclusive shelf price. Leave at 0 for B2B or US pre-tax pricing.
7. Read the result block for selling price, profit per unit, and the markup and margin side by side, then scan the break-even table to see how sensitive your volume requirement is to price.

The Formula

Two definitions, four rearrangements. Given cost C and selling price P, with gross profit G = P − C:

Markup % = (P − C) / C × 100          ← denominator is COST
Margin % = (P − C) / P × 100          ← denominator is PRICE

P = C × (1 + markup/100)              price from markup
P = C ÷ (1 − margin/100)              price from margin   (margin < 100)

margin = markup ÷ (100 + markup) × 100    markup → margin
markup = margin ÷ (100 − margin) × 100    margin → markup  (margin < 100)

Break-even units = Fixed costs ÷ (P − C)

The two conversion formulas are exact inverses of each other, so you can convert back and forth without drift. Note that margin has a hard ceiling of 100% and approaches it asymptotically as markup grows: a 400% markup is an 80% margin, a 900% markup is a 90% margin, and no finite markup ever reaches 100% margin. Markup, by contrast, has no ceiling.

Worked Examples

1. Keystone pricing, 100% markup. A gift shop buys a candle for $10.00. Keystone means doubling: markup 100%, so P = 10 × (1 + 1.00) = $20.00. Profit per unit is $10.00. Margin = (20 − 10) / 20 = 50%. This is the case people misquote most often, "we're on 100%" sounds like every dollar is profit, but half of each sale still goes back to the supplier.

2. A modest 50% markup. Same $10 candle, markup 50%: P = 10 × 1.50 = $15.00. Profit is $5.00. Margin = 5 / 15 = 33.33%. The markup number is 50 but the margin number is 33.33, a 16.67-point gap that materially changes a gross-profit forecast.

3. Working backwards from a margin target. A buyer is told the category must deliver a 25% margin on a $10.00 cost. Price = 10 ÷ (1 − 0.25) = 10 ÷ 0.75 = $13.33. The equivalent markup is 25 ÷ 75 × 100 = 33.33%. If she had mistakenly applied a 25% markup she would have priced at $12.50 and delivered only a 20% margin, a quarter of the intended gross profit missing.

4. Restaurant menu pricing. A pasta dish has a plate cost of $4.50 and the kitchen targets a 30% food cost, i.e. a 70% gross margin. Price = 4.50 ÷ 0.30 = $15.00. Expressed as markup that is 70 ÷ 30 × 100 = 233.33%, or a 3.33× multiplier, which is why menu-engineering guides talk about "multiplying food cost by 3 to 3.5".

5. Break-even at two prices. A maker has $5,000 of monthly fixed costs and a $10 unit cost. At a 50% markup ($15, $5 profit per unit) she needs 5,000 ÷ 5 = 1,000 units and $15,000 of revenue to break even. At a 100% markup ($20, $10 profit) she needs only 5,000 ÷ 10 = 500 units and $10,000 of revenue. Doubling the markup halved the volume requirement, the classic reason low-margin businesses are so fragile.

6. Adding VAT on top. The $15.00 price from example 2 in a 20% VAT jurisdiction becomes 15 × 1.20 = $18.00 on the shelf. The margin is still 33.33%, because the $3.00 of VAT is collected on behalf of the tax authority and never belonged to the business.

Where It Shows Up

• Retail buying and merchandising, open-to-buy plans, keystone and triple-keystone rules, and initial-markup targets set per department.
• Restaurants and bars, food-cost and pour-cost percentages are margins in disguise; menu prices are set by dividing plate cost by the target food-cost percentage.
• Wholesale and distribution, distributors typically quote thin margins (15 to 25%) while their retail customers apply a further markup on top, creating the two-stage channel price.
• E-commerce and marketplaces, after Amazon, Etsy or Shopify fees, the "cost" side must include referral and payment fees or the calculated margin will be fictional.
• Manufacturing and job shops, cost-plus quoting adds a fixed markup to direct cost to cover overhead and profit.
• Construction and trades, a builder's "10 and 10" (10% overhead, 10% profit) is a markup applied to job cost, not a margin on the contract price.
• Freelance and agency rates, pass-through costs (print, media, subcontractors) are usually marked up 15 to 25%.

Common Mistakes

• Quoting a markup as a margin. The most costly error. If your accountant asks for gross margin and you give them markup, every profit forecast is inflated. Always state which denominator you used.
• Applying a margin percentage as a multiplier. Multiplying cost by 1.40 does not give a 40% margin, it gives a 40% markup and a 28.57% margin. To hit a 40% margin, divide by 0.60.
• Including VAT or sales tax in the price when computing margin. Tax is not revenue. Strip it out first, otherwise a 20% VAT rate silently inflates apparent margin.
• Forgetting freight, duty and payment fees in cost. A 30% margin on invoice cost can collapse to under 20% once landed cost and 3% card fees are included.
• Assuming margin can exceed 100%. It cannot while cost is positive. If a spreadsheet reports a 120% margin, the formula has cost and price swapped.
• Confusing gross margin with net profit. Gross margin covers rent, wages, marketing and tax. A 50% gross margin business can easily be loss-making.

Frequently Asked Questions

What is the difference between markup and margin?

Markup is gross profit expressed as a percentage of cost: (price − cost) ÷ cost × 100. Margin is the same gross profit expressed as a percentage of the selling price: (price − cost) ÷ price × 100. Because the selling price is larger than the cost on any profitable sale, the margin figure is always smaller than the markup figure. A $10 item sold for $20 carries a 100% markup and a 50% margin simultaneously, the numbers describe the same $10 of profit from two different reference points. Suppliers and buyers tend to talk in markup because they price up from cost; accountants and investors talk in margin because their reference point is revenue on the income statement.

How do I convert markup to margin and back?

Use margin = markup ÷ (100 + markup) × 100 and markup = margin ÷ (100 − margin) × 100. Worked both ways: a 50% markup becomes 50 ÷ 150 × 100 = 33.33% margin; a 33.33% margin becomes 33.33 ÷ 66.67 × 100 = 50% markup. Handy anchors worth memorising are 10% markup = 9.09% margin, 25% markup = 20% margin, 33.33% markup = 25% margin, 50% markup = 33.33% margin, 100% markup = 50% margin, and 233.33% markup = 70% margin.

What markup should I use in retail?

It depends entirely on inventory turnover and category. Grocery and convenience run thin markups of roughly 10 to 25% because units move fast. Hardware, pet and general merchandise sit around 30 to 60%. Apparel, gifts, jewellery and furniture commonly use keystone (100%) or higher, because slow turns, markdowns and shrinkage have to be absorbed by the units that do sell at full price. The right question is not "what markup is normal?" but "what gross profit per square foot per month does this category need to deliver?", a 20% markup on stock that turns 12 times a year out-earns an 80% markup on stock that turns twice.

How do restaurants use markup for menu pricing?

Restaurants think in food-cost percentage, which is simply 100% minus gross margin. A 30% food-cost target means a 70% margin, which means dividing plate cost by 0.30, equivalent to a 233% markup or a 3.33× multiplier. Bars run tighter: a 20 to 25% pour cost implies a 75 to 80% margin, i.e. a 4 to 5× multiplier on liquor cost. In practice most kitchens vary the multiplier by item, using lower markups on high-perceived-value proteins (steak) and much higher ones on low-cost, high-margin items (pasta, soft drinks, coffee) so the blended food cost across the menu lands on target.

Why is wholesale markup lower than retail markup?

A wholesaler or distributor moves large volumes with low touch cost per unit: pallet in, pallet out, no shopfront, no shop staff, no consumer returns. Margins of 15 to 25% are viable at that volume. A retailer holds inventory for weeks, pays rent on selling space, staffs a floor, absorbs theft and markdowns, and sells one unit at a time, so it needs a much larger markup on a much smaller volume to cover the same overheads. The two markups stack: a $10 factory cost might leave the wholesaler at $12.50 (25% markup) and the retailer at $25.00 (100% markup on their $12.50 cost), giving a consumer price 2.5× the factory cost.

What is keystone pricing and is the 2× rule still valid?

Keystone means setting the retail price at exactly twice the wholesale cost, a 100% markup and a 50% margin. It survives because it is fast, easy to compute in your head, and historically produced enough gross profit to cover a traditional store's overheads. It is still a reasonable default anchor in apparel, gift, jewellery and homeware, but it is a starting point, not a law. Fast-turning commodities cannot support it (nobody pays 2× for milk), while designer, low-turn or heavily-marked-down categories often need triple keystone (200% markup, 66.7% margin) to survive end-of-season clearance. Use keystone as the first draft, then test it against your actual turnover and markdown rate.

Does VAT or GST change my markup calculation?

No, provided you keep VAT and GST out of both cost and price. Registered businesses reclaim input tax and remit output tax, so the tax passes through and never forms part of gross profit. Always calculate markup and margin on net (tax-exclusive) figures, then apply the tax rate at the end to produce the shelf price. A $10 net cost with a 50% markup is a $15 net price and a $18.00 gross price at 20% VAT, the margin remains 33.33%, not the 16.67% you would get by wrongly comparing net cost against gross price. If you are not VAT-registered, irrecoverable input tax genuinely is a cost, so include it in the cost figure and price up from there.

Can margin ever be higher than markup?

Not on a profitable sale. Since margin = markup ÷ (100 + markup) × 100 and the denominator always exceeds 100 for a positive markup, margin is strictly smaller. The two converge towards each other only near zero (a 1% markup is a 0.99% margin) and diverge without limit as markup grows, with margin asymptotically approaching but never reaching 100%. If your spreadsheet shows margin above markup, cost and price have been transposed somewhere in the formula.
