A “good” ROAS number pulled from a blog post means nothing if it doesn’t match your actual margin and repeat purchase rate.

DTC brands frequently chase a target ROAS borrowed from an industry benchmark or a competitor’s case study, without checking whether that number actually makes sense for their own margin structure and repeat purchase behavior. A 3x ROAS can be a great result for a low-margin, low-repeat product and a losing one for a brand whose product has much higher retention potential that the campaign never accounts for.

Optimizing purely toward a generic benchmark, rather than your own real numbers, routinely leaves real profit on the table in either direction, either scaling too cautiously because a borrowed benchmark seems unreachable when the brand’s real economics would support much more aggressive spend, or scaling too aggressively toward a benchmark that doesn’t reflect how thin the actual margin is once returns, discounts, and fulfillment costs are factored in.

This gets worse as brands scale, because the audience segments that produce a strong ROAS at low spend often aren’t large enough to sustain that same efficiency at higher budgets, and a target set once early on rarely gets revisited as the brand’s actual economics and audience saturation change over time.
