The Margin Benchmark Report 2026
Most ecommerce benchmarks stop at revenue and gross margin. The number that decides whether a brand survives is contribution margin: the profit left after every cost that moves with a sale. The median seven- and eight-figure brand runs on about 25% contribution margin, with a spread from 3% to 56%. Two brands with the same revenue can sit at opposite ends of that range, and only one is building a business.
Four numbers that frame 2026.
The median matters less than the spread, because contribution margin is where every other metric resolves. Break-even ROAS is its inverse. CAC payback is paced by it. Whether a returning customer is worth chasing depends on it. This report takes contribution margin apart rung by rung, segments the inputs by category and brand size, and shows the arithmetic so you can place your own brand inside the distribution rather than against a single average.
Contribution margin is a ladder, not a number.
Each rung strips out the next layer of variable cost. A brand is only as healthy as the rung it stops profitable on.
CM1 = Net revenue − Landed COGSCM2 = CM1 − (Fulfilment + Shipping + Payment & transaction fees)CM3 = CM2 − Variable marketing (the spend that scales with sales)Where the ladder starts depends on what you sell.
Gross margin (CM1) is set largely by category economics. Subscription and consumable models run 55-65% versus 40-50% for one-time purchase. Benchmark against your category, never against ecommerce as a whole.
Bars show the typical midpoint of each cited range. The gap from supplements (~66%) to electronics (~20%) is more than 3×, which is why a 35% CM3 target is comfortable for one category and structurally unreachable for another.
Returns are where CM2 quietly dies.
A return reverses the revenue but rarely the full cost. In high-return categories it is the difference between a healthy CM2 and a loss, and it is growing.
Online return rates have more than doubled since 2019, and roughly 9% of returns are estimated fraudulent. The practical consequence: in apparel a quarter of orders comes back, and the reversal lands squarely on contribution margin. Model returns net at the SKU level, not as a blended write-off.

The same CAC means different things.
What matters is how long the contribution margin from a customer's orders takes to repay what you spent to acquire them. That window is paced by margin, not effort.
Scale buys a few points, not a different game.
The contribution-margin spread (3-56%) is far wider than the operating-margin gap between size bands. In other words: how you run the ladder matters more than how big you are.
The operator targets that actually matter.
CM3 floor: 20-25%
Below 20% at CM3, growth borrows from the future. This is the line for sustainability.
Scaling on paid: ~35% CM3
Brands pushing hard on acquisition aim near 35% to fund the spend and still profit.
Break-even ROAS = 1 ÷ CM%
A 40% contribution margin means break-even at 2.5× ROAS. Your ROAS target is your margin, inverted.
LTV:CAC ≥ 3:1
Measured in contribution margin, not revenue. Anything less and acquisition is buying revenue, not profit.
