What does each distribution channel actually contribute after fees, ads, and returns?

MetricContribution margin per channel after channel fees, fulfillment, variable marketing and returns

Unit% contribution margin of channel net revenue

Bar chart of margin after channel-specific costs (Amazon fees, retail markups, ads). Direct usually best. Build by computing per-order P&L per channel. Marketplace can be a unit-economics trap despite high revenue. Example: Direct 42%, Marketplace 12% (after Amazon fees and ads), Wholesale 28%, Partners 22%.

P&L

Profit and loss statement. Revenue minus cost of goods sold minus operating expenses, down to operating profit.

DTC and consumer brands selling across owned store, third-party marketplace and wholesale, 2025 to 2026. Definition used here is the four-layer version: CM4, meaning CM3 after variable marketing, further less channel and marketplace fees, so channel commissions and retail chargebacks are inside the number. · The headline finding across sources is counterintuitive and worth stating plainly: channel contribution percentages converge more than operators expect, while absolute contribution per unit does not. Eightx reports the same product at 34% DTC, 30% Amazon and 34% wholesale, but roughly $10 less per unit on wholesale. So a percentage-only chart will mislead on capacity and cash decisions. Marketplace economics have deteriorated on a trend basis: Marketplace Pulse puts total Amazon cost above 50% of revenue for a typical seller (15% referral, 20% to 35% FBA, up to 15% advertising), with the average seller's Amazon fee load rising from 19% to 26% of revenue since 2020. Wholesale carries costs that are frequently omitted entirely from channel P&Ls, notably 3% to 8% of sales in compliance chargebacks. Returns must be loaded per channel, since social commerce runs 23.7% against DTC-only at 14.8% in one 35-brand portfolio cut.

The channel with the tallest revenue bar has the shortest contribution bar, and the gap between the two widens each period as fee load and advertising creep, so scaling the biggest channel is actively shrinking profit.

Marketplace is 58% of revenue and 21% of contribution. Channel fee load moved from 19% to 26% of that channel's revenue over three years, marketplace returns run 19.1% against 14.8% direct, and the channel's CM4 is now 7% against 31% on owned direct.

• Report contribution in absolute currency per unit alongside the percentage. Channel percentages converge (34% DTC, 30% marketplace, 34% wholesale in one benchmark) while absolute contribution per unit does not, and capacity and cash decisions run on the absolute.
• Load every channel-specific cost before comparing, including marketplace referral and fulfillment fees, retail compliance chargebacks at 3% to 8% of wholesale sales, and a returns reserve at the channel's own rate rather than the blended rate.
• Track fee load as a moving line per channel. Average Amazon fee load rose from 19% to 26% of revenue since 2020 with advertising roughly 40% of it, so channel margin decays without any decision being taken.
• Add the cash dimension to the channel decision, not just the margin. DTC collects in about 2 days against 45 to 73 days for wholesale-dominant models, so two channels at identical contribution percentages have very different funding requirements.
