What is contribution margin and why do people say it matters more than gross margin for a startup?

A starting point

Gross margin is revenue minus the direct cost of delivering your product, while contribution margin also strips out the variable costs to serve and support each customer (payment fees, hosting per user, support time). Contribution margin is what actually funds your overheads and CAC, so it is the number that tells you whether more customers make you healthier or poorer. As a starting point, compute per-unit contribution margin before you spend a rupee on scaling, because negative contribution margin means growth burns you faster.

Why we picked it This is the cleanest plain-language separation of the two margins we found, and it walks through both formulas with actual dollar numbers instead of jargon.

Contribution Margin vs. Gross Margin: What's the Difference?

From Shopify by Shopify About 8 minute read

Gross margin subtracts the direct cost of producing the good or service, while contribution margin also subtracts the variable costs of each sale (sales commissions, shipping, transaction fees), so contribution margin is almost always the lower and more honest number.
The worked example makes it concrete: a product with 20 in net sales and 10 in variable costs has a 50 percent contribution margin, and the article shows the gross margin math on a separate case so you can see how the two diverge.
The higher your contribution margin, the more of each sale is left to cover fixed costs like payroll and rent, which is why founders watch it when pricing and deciding what to sell more of.
