Markup is the amount you add on top of what a product costs you, expressed as a percentage of that cost. In plain words: markup percentage = (selling price − cost) ÷ cost × 100. If a candle costs you $8 to make and you sell it for $20, you added $12, which is a 150% markup. Markup is how you move from "what I paid" to "what I charge," and it is the single number that decides whether your store makes money or quietly loses it. It is also the number most new founders get tangled up with, because they confuse it with profit margin, and the two are not the same thing at all.
Why markup matters
Markup is the bridge between your costs and your price. Every other part of running a store, from cost of goods sold to shipping to the ad you ran on Instagram, eventually has to be paid for out of the gap between what you spent and what you charged. That gap starts with markup. Set it too low and you can be busy, shipping orders every day, and still end the month with less cash than you started with. Set it thoughtfully and you give yourself room to absorb the things that always go wrong: a discount code that spread too far, a return, a shipping cost that crept up.
The reason this matters more than it used to is that the cost of getting a customer keeps climbing. Average ecommerce customer acquisition cost now sits between roughly $68 and $84, and it jumped 40% to 60% between 2023 and 2025, according to Mobiloud (2026). If you only marked your product up by 40% and it costs you $70 to acquire each buyer, you are underwater before the package ships. Markup has to be high enough to feed the ad machine and still leave something behind.
It also matters because thin margins are the norm, not the exception. Across thousands of stores, gross margins average around 45% while net profit margins average only about 10%, per Onramp Funds (2025). That tells you how much disappears between the price tag and the bank deposit. The cushion you build with markup is what survives that long slide from gross to net.
Finally, markup is a lever you can actually pull. A 1% price increase produces roughly an 11% improvement in operating profit on average, a figure often cited from pricing research and echoed by Power Digital (2025). Most founders spend months chasing more traffic when nudging the price up a little would have done more for the bottom line. Understanding markup is what lets you see that lever in the first place.
There is a psychological trap worth naming here too. New founders tend to price from fear. You look at your product, imagine a stranger judging the price, and your instinct is to make it lower so nobody feels ripped off. The trouble is that the stranger is not actually price-shopping your costs; they are weighing the product against the value it gives them. A $9 price does not feel "fair" to them, it often feels cheap and forgettable. Meanwhile that low number is the one thing standing between you and a sustainable business. Markup is where founder psychology and business math collide, and the math has to win, or there is no business to have feelings about.
How to calculate markup
Markup math is simple once you slow down. You need two numbers to start: your cost (what the unit actually costs you, landed) and your selling price (what the customer pays). From there:
- Find the dollar markup. Subtract your cost from your selling price. Selling price − cost = markup in dollars.
- Turn it into a percentage. Divide that dollar markup by your cost, then multiply by 100. (Markup ÷ cost) × 100 = markup percentage.
- Going the other way. If you know the markup you want and your cost, the price is: cost × (1 + markup ÷ 100). A 60% markup on a $25 item is $25 × 1.60 = $40.
The detail that trips people up is the word cost in step two. Markup is always measured against cost, never against the selling price. That single fact is the whole reason markup and margin diverge, and we will get to that next. For now, lock in the anchor: markup divides by what you paid.
Let us run a few quick reps so the formula stops feeling abstract. A phone case costs you $4 and you sell it for $24: the markup is $20, and $20 ÷ $4 = 500%. That is a 5x markup, which sounds enormous, and for a cheap accessory it is normal. A pair of boots costs you $40 and sells for $120: markup is $80, and $80 ÷ $40 = 200%, or 3x. A bag of specialty coffee costs you $9 and sells for $18: markup is $9, and $9 ÷ $9 = 100%, the classic keystone double. Same formula every time, wildly different results, because the right markup depends entirely on the category and the costs underneath it.
It also helps to be able to work backward, because in practice you often start from the price the market expects rather than from your cost. If shoppers in your niche expect to pay around $30 and your landed cost is $10, your markup is fixed for you at ($30 − $10) ÷ $10 = 200%, whether you like it or not. The job then becomes getting your cost down through better sourcing or higher order volume, because at a market-set price your only path to a fatter margin is a leaner cost.
One more practical note. The "cost" you use should be your true landed cost, not just the supplier invoice. Include shipping to your warehouse, import duties, payment processing fees if you can estimate them, and any per-unit packaging. A product that looks like it costs $10 from the supplier often costs $13 to $14 by the time it is sitting ready to ship. Marking up the wrong, lower number is one of the quietest ways stores lose money, and it is worth getting your cost of goods right before you ever pick a markup. The same care applies when you buy at wholesale and resell: the wholesale price is your cost, and your markup sits on top of it.
A real-feeling example
Say Maya is launching a small candle brand. Her supplier charges $6 per candle. Shipping the candles to her apartment works out to $0.80 each, and the jar, wick trim, and box add another $1.20. Her true landed cost is $8 per candle, not $6. She wants to sell them at $24.
Her dollar markup is $24 − $8 = $16. As a percentage, that is ($16 ÷ $8) × 100 = 200% markup. In retail shorthand, she is selling at "3x cost," because $8 × 3 = $24. That feels healthy, and for a handmade product it is reasonable. But here is the part Maya needs to see clearly: that 200% markup does not mean she keeps 200% of anything, and it does not even mean she keeps two thirds of the price. Out of every $24 sale, $8 is the candle itself, leaving $16 before she has paid for the website, the ad that found the customer, the card-processing fee, or her own time. Her markup looks big. What lands in her pocket is much smaller, and the next section explains exactly why.
Markup vs. profit margin
This is the confusion that costs founders real money, so it is worth being slow and exact. Markup and profit margin describe the same gap between cost and price, but they divide that gap by different numbers. Markup divides by cost. Margin divides by the selling price. Because the selling price is always bigger than the cost, the margin percentage is always smaller than the markup percentage for the same product.
Take a clean example. You buy something for $10 and sell it for $15. The gap is $5 either way. Your markup is $5 ÷ $10 = 50%. Your margin is $5 ÷ $15 = 33%. Same product, same five dollars, two very different percentages. A 50% markup is a 33% margin. They are never equal, and the higher your markup climbs, the wider the two numbers spread apart.
Here is a small conversion table you can keep in your head:
- 25% markup = 20% margin
- 50% markup = 33% margin
- 100% markup (keystone) = 50% margin
- 150% markup = 60% margin
- 200% markup = 67% margin
- 300% markup = 75% margin
Notice that doubling your money (a 100% markup) gives you a 50% margin, not a 100% one. This is the exact spot where new sellers overestimate their profitability. Someone tells you they price at "100% markup" and you might assume they keep all of the price as profit; in reality they keep half of the price before any other expense. That gap between perception and reality is why margins land where they do. Gross margins across thousands of ecommerce stores average about 45% and net margins about 10%, again per Onramp Funds (2025), even though the headline markup numbers people quote sound much larger.
A 50% markup is not a 50% margin. It is a 33% margin. Mix the two up when you set prices and you can run a busy store that loses money on every order it ships.
If you ever need to convert between the two yourself, the formulas are short. To get margin from markup: margin = markup ÷ (1 + markup), with both as decimals. A 100% markup is 1.0, so margin = 1.0 ÷ 2.0 = 0.50, or 50%. To go the other way, markup = margin ÷ (1 − margin). A 40% margin is 0.40, so markup = 0.40 ÷ 0.60 = 0.667, or about 67%. You do not need to memorize these, but it is reassuring to know the conversion is fixed and mechanical, not a matter of opinion.
The practical rule: when you talk to a supplier or read a "what should I charge" guide, check which number they mean. When you plan your own profitability, think in margin, because margin is the share of each sale that is actually yours to spend. When you set a price from a cost, it is often easier to think in markup, because you are multiplying up from the cost you know. Fluent founders move between the two without flinching, and getting comfortable with both is one of the highest-leverage things you can learn early.
One more reason the distinction is not just pedantry: it changes the decisions you make under pressure. Imagine a supplier offers to drop your unit cost from $10 to $8 if you order more. In markup terms at a $20 price, you just went from 100% markup to 150% markup, which sounds like a modest bump. In margin terms you went from a 50% margin to a 60% margin, which on $20 is a full extra $2 of gross profit per unit, real money that compounds across every order. Whether that volume deal is worth tying up cash in inventory and committing to a higher minimum order quantity is a margin question, and you cannot answer it cleanly if you are still thinking in markup.
How much should you mark up?
There is no universal answer, but categories cluster into recognizable ranges, and knowing yours keeps you from pricing in the dark.
Apparel and fashion. Clothing has historically run on keystone pricing and a bit above, landing around 100% to 150% markup, which is a 50% to 60% margin. But the practical floor has crept up. Industry data from Eightx (2026) shows the working market average has moved to roughly 2.1x to 2.4x production cost, with pure direct-to-consumer brands often pricing at 3x to 5x to absorb the heavy marketing spend that selling online requires. DTC apparel brands frequently target a 55% to 65% gross margin.
Food and grocery. This is the low-margin end of the spectrum. Cost of goods often eats 70% to 75% of revenue in grocery, leaving gross margins in the 25% to 30% range and net margins as thin as 1% to 3%, per Grocery Dive (2024). Food works on volume, not markup. If you are selling consumables, plan for thin margins and high repeat purchase rather than a fat markup per unit.
Jewelry. The most generous category. Average jewelry markups run well over 100%, with luxury and branded pieces reaching far higher; analysis cited by Jewelry Mavericks (2025) puts typical markups in the 50% to 100% range for many sellers and around 116% for large branded retailers, with some segments far above that. The exception is loose diamonds, where online competition has compressed markups to under 20%. Materials cost matters: handmade and design-led jewelry carries far more markup than commodity gold by weight.
Beauty, accessories, and home goods. These typically sit at the higher end, 100% to 300%+ markup, because perceived value is driven by branding rather than raw materials. A $4 lip product selling for $20 is a 400% markup and is completely normal in beauty. This is also why building a private label brand can support fatter markups than reselling generic products.
Keystone pricing is the classic shortcut: double your cost. A $10 item becomes $20. That is a 100% markup and a 50% margin, and for generations it was the retail default. It is fast, it is easy to explain, and it bakes in a respectable margin. But keystone is no longer a safe floor for online sellers, because it was designed for a world without paid acquisition. If half your price is product cost and you then have to pay $25 to acquire the customer on an $80 order, keystone alone will not survive contact with your ad account.
If you are buying products to resell rather than making them, this is also where dropshipping math gets unforgiving. Dropshipped goods usually carry a high unit cost relative to their price, which leaves a thin gap to begin with. Stack rising ad costs on top of a thin gap and there is simply nothing left, which is why so many dropshipping stores look busy and still fail. The fix is not a secret traffic source; it is a product whose markup is fat enough to feed the ad machine.
Which brings up the real reason to mark up generously online: your markup has to survive ad costs and discounts. The average cost per lead on Meta rose to $27.66 in 2025, up nearly 21% year over year, and Meta CPMs hit record highs, according to Threadpoint (2026). That cost comes straight out of your gross profit. A widely used rule of thumb is to aim for at least a 60% to 70% gross margin so paid acquisition has room to work; brands below that line struggle to scale profitably, as noted by TrueProfit (2026). Then layer in reality: you will run a 15% welcome discount, you will eat returns, payment processing takes about 3%. Price as if every order will get discounted and marketed to, because most of them will.
It is worth walking through a full order to see how fast a healthy-looking markup gets eaten. Suppose you sell a $50 product that costs you $15 landed. On paper that is a 233% markup and a 70% gross margin, which sounds excellent. Now run a real order. A 15% welcome code knocks the price to $42.50. Card processing of about 3% takes $1.28. You ship it for $5. The customer found you through an ad, and your blended acquisition cost is $20. Add it up: $15 product + $1.28 processing + $5 shipping + $20 acquisition = $41.28 in costs against $42.50 collected. You kept $1.22 on a "70% margin" product. That is not a pricing horror story, it is a Tuesday, and it is exactly why the gross margin you start with has to be generous. The same order at a $70 price, an 80% gross margin, leaves you something like $16 after all of that, which is the difference between a hobby and a business.
The honest way to land on a markup that holds up is to work backward from your average order value and your customer acquisition cost, not forward from a percentage that feels nice. And do not stop at the first order. A customer who comes back three times turns a painful first-order CAC into a bargain, which is why customer lifetime value belongs in the same conversation as markup. Your first sale might barely break even on purpose, with the markup carrying you to profit on the repeat. A smooth checkout and a reason to return are what make that bet pay off.
Common mistakes with markup
- Confusing markup with margin. The big one. Quoting a 50% markup and assuming you keep 50% of the sale. You keep 33%. This single mix-up has sunk more first stores than bad products ever did.
- Marking up the wrong cost. Using the bare supplier invoice instead of true landed cost. Forget the inbound shipping, duties, and packaging and your real margin can be 10 to 15 points thinner than your spreadsheet claims.
- Ignoring ad costs when setting price. Picking a markup that looks fine in isolation, then discovering that acquisition costs consume the entire gap. With CAC up 40% to 60% in two years, a markup that worked in 2022 may not work now.
- Forgetting discounts are permanent. Setting prices at full margin while running 20%-off codes year round. If you always discount, your discounted price is your real price, and you must mark up enough to absorb it before you launch the first sale.
- Pricing purely off competitors. Copying a rival's price without knowing their costs, volume, or sourcing. Their $29 might be built on a $4 unit cost you cannot match. Their number is not your number.
- Underpricing to feel competitive. Going low to win sales, then realizing you have no room for the business to breathe. Underpricing is one of the fastest ways stores bleed profit, and a 1% price increase can lift operating profit around 11%, so the cost of timidity is real.
- Setting it once and never revisiting. Treating markup as a launch-day decision. Supplier costs change, shipping changes, ad costs climb. Markup is a number you revisit every quarter, not a tattoo.
How Zentrix helps
Pricing well is partly math and partly knowing the benchmarks for your category, and that is exactly the kind of work Zentrix is built to take off your plate. When you describe your idea, Zentrix builds the whole business around it: the brand, the store, the legal docs, and suppliers, which means your real costs are visible from the start instead of being a guess. Knowing your true landed cost is the foundation of a markup that actually holds, and our business plan generator and product description tool help you frame the value that justifies a healthy price rather than racing to the bottom. Even something as small as a strong name from the store name generator adds perceived value, and perceived value is what lets a price stick.
We will not pretend a tool can set the perfect price for you, because your market and your costs are yours. What Zentrix does is remove the friction around the decision: a store that is ready to sell, sourcing options with real numbers attached, and a clear view of the costs your markup has to cover. If you are weighing your options, our comparison page and pricing lay out where we fit, and you can read more on the blog or just get started.

Frequently asked questions
Is markup the same as profit margin?
No, and confusing them is the most common pricing mistake new founders make. Markup is the gap between cost and price divided by your cost; margin is that same gap divided by the selling price. A 50% markup equals a 33% profit margin, and the higher your markup, the wider the two numbers diverge.
How do I calculate markup percentage?
Subtract your cost from your selling price to get the dollar markup, then divide that by your cost and multiply by 100. So an item costing $10 and selling for $15 has a $5 markup, which is ($5 ÷ $10) × 100 = 50% markup. Always divide by cost, never by the selling price.
What is keystone pricing?
Keystone pricing means doubling your cost to set the price, which is a 100% markup and a 50% gross margin. It is a fast, traditional retail default, but for online stores it is often too low because it does not leave room for the rising cost of paid advertising and discounts.
What is a good markup for an online store?
It depends on your category, but many ecommerce sellers aim for markups that produce a 60% to 70% gross margin so paid acquisition has room to work. Apparel often runs 2x to 3x cost, beauty and accessories higher, and food much lower. Whatever the range, price high enough to survive ad costs, returns, and routine discounts.
Why do my margins feel so thin even with a big markup?
Because markup is only the first gap, before advertising, shipping, returns, processing fees, and your own time come out. Across thousands of stores, gross margins average around 45% but net margins land near 10%. A large headline markup can still leave a small real profit once every other cost is paid.
Should I match my competitors' prices?
Be careful. A competitor's price reflects their costs, volume, and sourcing, none of which you can see. If their unit cost is lower than yours, copying their price can put you underwater. Use competitor prices as a reference for what the market expects, but set your own number from your own true landed cost and target margin.
