Apparel DTC: Topline ROAS 2.8x, Contribution ROAS 1.4x. Wrong Operating Metric.

A $6M GMV apparel DTC brand came in last month. AOV $78. Topline ROAS reported by Meta and Google was 2.8x and trending stable. The founder believed paid was profitable and was planning to triple monthly spend over the next quarter.

The contribution-margin walk had never been done at the channel level. Cost of goods sold was 38 percent of revenue. Fulfillment, returns, and platform fees added another 18 percent. Real contribution-margin ROAS was 1.4x, not 2.8x.

The diagnosis (3 sentences)

The brand was operating against a metric that overstated paid profitability by 50 percent. Tripling spend against a 1.4x contribution ROAS would have produced significantly more unprofitable revenue, not more profit. The decision to scale was based on a number that did not exist.

The allocation move

  • Pause the planned spend increase. Hold at current monthly run rate for 60 days while the metric switch happens.
  • Build the contribution-margin walk by channel. Calculate revenue from paid minus COGS minus fulfillment minus returns minus platform fees, divided by paid spend. Do this for each channel, not just blended. Channel-level contribution ROAS varies significantly because returns rates differ by channel (TikTok-acquired customers in apparel often have 30 to 40 percent higher return rates than Meta-acquired).
  • Reset the operating metric. Replace topline ROAS in all internal dashboards and board reporting with contribution-margin ROAS. Topline can stay as a leading indicator if useful, but the decision metric is contribution.
  • Set a new hurdle: any channel below 1.8x contribution-margin ROAS gets evaluated for pause within 60 days. Below 1.4x is paused immediately. Decision rules pre-committed in writing.
  • Investigate the returns rate by acquisition channel. If TikTok returns are running 18 percent versus Meta at 11 percent, the creative is acquiring buyers with looser purchase intent. Tighten the creative offer or pause the channel.

When this applies. When it does not.

Applies: DTC brands operating against topline ROAS in high-COGS categories (apparel, supplements, home goods, footwear). Topline ROAS appears acceptable (2.5x to 3.5x) but the brand cannot reconcile paid contribution to P&L. Post-seed to Series A scale.

Does not apply: Low-COGS categories (digital products, high-margin jewelry above 80 percent gross margin) where topline and contribution ROAS are close enough that the gap is immaterial. Brands already operating against contribution margin (the metric switch is done; the question is just scale).

A founder line, anonymized

“I was about to triple paid. The audit was 4 pages of contribution-margin math that showed me I was breaking even on every paid order. Tripling that would have tripled the breakeven, not the profit. The metric switch was the entire fix. We held spend flat, fixed the return rate on TikTok, and got contribution ROAS to 2.1x in 90 days.”
