Which lines carry the margin?
№ 198 · Margin per unit by line
Definition
MetricGross and contribution margin per unit, broken out by product line
Unit% margin and absolute margin per unit, by line
Bar of margin $ per unit across business lines. Reveals which lines fund others. Build from per-line P&L. Pricing or cost issues show up here before they hit blended margin. Example: Line A $42/unit, Line B $18/unit, Line C $4/unit (loss-maker, investigate).
- P&L
- Profit and loss statement. Revenue minus cost of goods sold minus operating expenses, down to operating profit.
Benchmarks
| Bottom 30% | Median | Top 30% |
|---|---|---|
| 46% or below gross margin, under 10% contribution margin | about 57% gross margin, about 25% contribution margin | 64% or better gross margin at line level, 35%+ contribution margin after fulfilment and variable marketing |
Public and private DTC and consumer brands. Gross margin bands from latest 10-K filings (n=11 to 13 companies); contribution margin bands from merchant panels covering 800 to 33,000 brands, 2024 to 2026 data. Contribution margin here is gross profit less fulfilment, shipping, payment processing, returns reserve and variable marketing. · Gross margin and contribution margin are not interchangeable and the gap between them is where most line-level decisions go wrong. Merchant panel data puts median gross margin at 60 to 70% against a median contribution margin of roughly 25%, so about two thirds of apparent margin is consumed by costs the gross view excludes. Second caution: within-category spread is wider than between-category spread. Pet brands show a 47 point gap between top and bottom quartile (74% against 27%), which is wider than the gap between the best category (beauty near 70%) and the worst (food near 40%). Comparing a line to a cross-category average is therefore close to meaningless.
| Category | Bottom 30% | Median | Top 30% |
|---|---|---|---|
| Beauty and personal care | under 60% gross | about 69% gross, 25 to 35% contribution | 71%+ gross, 30%+ contribution |
| Apparel and fashion | under 46% gross, under 10% contribution | 53 to 55% gross, 12 to 18% contribution | 59%+ gross, 18%+ contribution |
| Food and beverage CPG | under 10% gross | under 35% gross, 4 to 10% contribution | about 40% gross |
| Electronics and small appliances | under 15% gross | 15 to 30% gross, about 15% contribution | 30% gross |
| Pet | 27% gross | not separately published | 74% gross |
When it looks bad
One or two bars carry nearly all the gross profit while a long tail sits at or below line-level breakeven, and the tail bars are close enough to each other that no single line ever looks bad enough to kill.
The top 2 of 14 lines produce 71% of gross profit. Six lines return under 12% contribution after fulfilment and returns, and three of those six are the ones marketing is currently scaling.
What to do about it
- Rebuild the chart on contribution margin rather than gross. Allocate fulfilment, returns reserve, payment fees and variable marketing down to the line. Merchant panel data puts median contribution at about 25% against a 60 to 70% gross median, so roughly two thirds of apparent line margin sits in costs the gross view hides (Finaloop 2024, Triple Whale 2025).
- Reserve for returns at booking rather than at refund. Apparel returns run 25 to 40% of gross sales, so carrying the hit at refund time overstates reported line margin for a full quarter and flatters exactly the lines that need scrutiny (Eightx, 2026).
- Set a line-level kill rule before the review starts, for example any line under 12% contribution for two consecutive quarters goes to a price test and then to discontinuation. Without a pre-agreed rule the tail survives every review on narrative grounds.
- Benchmark each line against its own category quartile, not the company average. Within-category spread reaches 47 points, wider than the gap between the best and worst categories, so a cross-category comparison will systematically mislabel good and bad lines (Finaloop 2025, n=800+ brands).
