A direct-to-consumer brand's economics live on three lines. Contribution margin per unit. Payback period on customer acquisition cost. Repeat purchase rate at twelve months. Everything else — channel mix, creative performance, SKU breadth — flows from these three. A brand whose three lines work scales reliably; a brand whose three lines do not work cannot be saved by scale.
Contribution margin per unit — revenue minus COGS minus variable fulfilment cost — is the line that determines whether the unit economics work at all. Healthy D2C contribution margin is typically 50% or higher for consumer goods sold through owned channels; below 40% the brand has very little room to absorb marketing cost and still profit. Brands whose contribution margin is structurally constrained — by category dynamics, by sourcing realities, by competitive pricing — need to either find ways to lift it or accept they are operating in a category where the economics will always be tight.
Payback period on CAC — how many weeks of revenue from a new customer it takes to recoup the cost of acquiring them — is the line that determines how fast the brand can scale safely. A payback period below 8 weeks means the brand can scale aggressively. A payback period of 12-20 weeks means the brand can scale carefully. A payback period over 26 weeks means the brand is scaling on capital, not on cash, and is at structural risk if access to capital tightens.
Repeat purchase rate at twelve months is the line that determines whether the brand has a business or has a marketing campaign. Below 20% repeat, the brand is essentially acquiring new customers every cycle — a treadmill that requires constant marketing spend. Above 35% repeat, the customer base compounds and marketing spend becomes increasingly optional. The most important brand-level investment is whatever lifts the twelve-month repeat rate, even when the short-term effect on revenue is flat.
The brands inside Wearon Studio are operated against these three lines as the primary metrics. Other metrics matter, but the three lines decide. one of the group’s former brands repeat-purchase rate is explicitly the leading metric the operating team manages to — and the discipline of refusing campaigns that would lift sessions but compromise the repeat number is what compounds.
