What Is Markup and How Do You Calculate It?

Markup is the percentage you add to a product's cost to arrive at the selling price. It's the most common pricing method for eCommerce brands, retailers, and wholesalers because it directly ties your price to what you paid for the product. The markup formula is straightforward: take the difference between your selling price and your cost, divide by the cost, and multiply by 100. For example, if a product costs $25 and you sell it for $50, your markup is 100% — also called a "keystone" markup in retail.

Our free markup calculator lets you solve in three directions. If you know your cost and selling price, it finds your markup percentage. If you know your cost and target markup, it calculates the selling price. And if you know your selling price and target markup, it works backwards to find your maximum allowable cost — which is incredibly useful when sourcing products or negotiating with suppliers.

Markup vs. Margin: Why the Difference Matters

Markup and margin are the two most confused terms in eCommerce pricing. They both measure profit, but from different angles. Markup is profit as a percentage of cost. Margin is profit as a percentage of the selling price. The same transaction produces different numbers depending on which metric you use — and mixing them up can cost you thousands in mispriced inventory.

Here's the critical relationship: a 100% markup equals a 50% margin. A 50% markup equals a 33.3% margin. The conversion formula is: Margin = Markup ÷ (1 + Markup). This is why our calculator shows both metrics side by side — so you never accidentally set a 50% markup thinking it's a 50% margin (which would actually require a 100% markup).

If you're evaluating whether your pricing covers ad costs, use our Contribution Margin Calculator to factor in COGS, shipping, fees, and advertising spend at the unit level.

When to Use Markup vs. Margin

Use markup when setting prices from cost — it tells you how much to add. Use margin when analyzing profitability from revenue — it tells you what percentage you keep. Most eCommerce operators use markup for pricing and margin for reporting. If your finance team talks in margins but your buying team thinks in markups, our conversion table bridges the gap instantly.

How to Set the Right Markup for Your eCommerce Store

There's no universal "correct" markup — it depends on your category, competition, brand positioning, and customer acquisition costs. But there are proven frameworks that the best DTC brands use to price profitably.

Factor in All Your Costs, Not Just COGS

The biggest pricing mistake eCommerce brands make is calculating markup against product cost alone. Your true cost includes COGS, inbound shipping, packaging, payment processing fees (typically 2.9% + $0.30), and platform fees. A product that "costs" $20 from your supplier might have a true landed cost of $26 once you add shipping and fees. Marking up the $20 by 100% gives you a $40 price with $14 profit. Marking up the real $26 gives you a $52 price with $26 profit — a massive difference in sustainability.

Work Backwards from Your Target ROAS

If you're running paid ads, your markup needs to support your customer acquisition cost. A product with a 50% markup (33% margin) leaves very little room for advertising. Most DTC brands need at least a 3x markup (200%) to profitably scale paid media. Use our ROAS Calculator to find your break-even ROAS, then set your markup high enough to leave room for ad spend and still turn a profit.

Keystone Markup and Beyond

The "keystone" markup — doubling your cost (100% markup, 50% margin) — is a retail standard, but it's often not enough for eCommerce. After payment processing, shipping subsidies, returns, and advertising, a keystone markup can leave you breaking even or losing money. Most successful Shopify stores operate at 150%–300% markup on their hero products, with lower markups on commodity or loss-leader items that drive traffic.

Markup Strategies for Different eCommerce Models

Dropshipping

Dropshipping margins are tight because you don't control production costs. Target 100%–200% markup minimum. Your leverage is in marketing efficiency — lowering your cost per acquisition rather than increasing markup.

Private Label / Own Brand

Private label gives you the most pricing power. Brands in beauty, supplements, and apparel routinely run 200%–500% markup because they control branding, formulation, and perceived value. Focus on building brand equity to defend your markup against competitors.

Wholesale to Retail

If you sell wholesale and retail, you need to price wholesale at a markup that still leaves room for retailers to add their own markup (typically 50%–100%). A common structure: you produce at $10, wholesale at $20 (100% markup), retailer sells at $40 (100% retail markup).

Common Markup Mistakes That Kill Profitability

The first mistake is confusing markup with margin — a 50% margin requires a 100% markup, not a 50% markup. The second is ignoring variable costs like returns (which average 20%–30% in fashion eCommerce) and chargebacks. The third is racing to the bottom on price: competing on markup alone in a commoditized category is a losing strategy. Instead, invest in brand differentiation, better creative, and customer experience to justify premium pricing.

Markup Formulas at a Glance

Every eCommerce operator should have these formulas memorized — or bookmarked. The markup formula calculates how much you're adding to your cost: Markup % = ((Selling Price − Cost) ÷ Cost) × 100. The selling price formula reverses it: Selling Price = Cost × (1 + Markup % ÷ 100). And the cost formula works backwards from price: Cost = Selling Price ÷ (1 + Markup % ÷ 100). That last formula is especially useful when sourcing — if a product retails for $79 and you need a 200% markup, your maximum cost is $79 ÷ 3.0 = $26.33.

The markup-to-margin conversion catches most people off guard. A 50% markup is only a 33% margin. A 100% markup is a 50% margin. A 200% markup is a 67% margin. The relationship is not linear, which is why our calculator includes a full conversion table every time you run the numbers.

How Top DTC Brands Think About Pricing

The best eCommerce brands don't just set a markup and forget it. They build a pricing architecture where hero products carry high markups (200%+) to fund customer acquisition, while accessory or consumable products use lower markups but higher purchase frequency to drive lifetime value. Subscription bundles, volume discounts, and loyalty pricing all shift the effective markup across the customer journey.

If you're spending on paid media through Meta or Google, your markup needs to fund your cost per click and still deliver a positive return. Run your numbers through our Ad Spend Calculator to see exactly how much budget your current markup can support — and whether you need to adjust pricing before scaling spend.
