What Is CM2? (Contribution Margin After Fulfillment)

Contribution Margin 2 (CM2) is CM1 minus your variable fulfillment costs — outbound shipping, payment processing, 3PL pick-pack fees, and a returns reserve. It's the dollar amount each order generates AFTER everything it takes to land the product in the customer's hands, but BEFORE any marketing spend. CM2 is the single most important number for sizing your maximum allowable Customer Acquisition Cost (CAC): if CM2 = $52, your first-order break-even CAC is $52.

How CM2 is calculated

CM2 (dollars) = CM1 (dollars) minus variable fulfillment.

CM2 (percent) = CM2 dollars divided by Revenue, times 100.

Variable fulfillment = outbound shipping + payment processing fees + 3PL pick-pack + returns reserve. Anything that scales with each order shipped goes here. Anything fixed (warehouse rent, 3PL minimums, customer-support payroll) does not.

A worked example

Same DTC beauty brand from the CM1 definition. CM1 was $62 per $80 serum. Variable fulfillment per order:

• Outbound shipping: $6.00
• Payment processing: 2.9% of $80 = $2.32
• 3PL pick-pack: $1.00
• Returns reserve: 4% × ($18 COGS + $7 fulfillment) = $1.00

Total variable fulfillment = $10.32. CM2 = $62 − $10.32 = $51.68, or 64.6 percent. That $51.68 is the maximum the brand can pay to acquire the customer and still break even on the first order.

What's a good CM2?

Vertical-dependent. Composite 2026 ranges:

• Beauty / personal care DTC: 55 to 68 percent
• Apparel DTC: 38 to 55 percent
• Outdoor / hardgoods DTC: 32 to 48 percent
• Food and beverage DTC: 18 to 32 percent
• Subscription consumables: 50 to 65 percent (replenishment lowers effective fulfillment %)

The most common mistake

Calling CM2 "after marketing." That's CM3. CM2 is the layer BEFORE marketing spend — it represents the headroom you have FOR marketing, not what's left AFTER it. Confusing the two layers leads founders to set max CAC against the wrong number: against CM3 (too low; you'd never spend), or against gross margin (too high; you go underwater). CM2 is the right benchmark.

CM2 is the input to max-allowable-CAC budgeting. For the full framework that walks CM1 → CM2 → CM3, the DTC-specific cost lines (3PL, payment fees, returns reserve), benchmarks from 35 brands, and the link to CAC, see our contribution margin pillar.

Frequently Asked Questions

what goes into variable fulfillment for cm2?

Outbound shipping, payment processing fees, 3PL pick-pack (and storage if variable per unit), and a returns reserve. Anything that scales with each order shipped. Fixed warehouse rent, 3PL minimum commitments, and customer-support payroll do not belong here — they sit below CM2 in operating expenses.

why is cm2 the max-CAC ceiling, not CM1 or gross margin?

Because CM2 is what each order actually brings home after both COGS AND fulfillment. Gross margin (or CM1) ignores fulfillment, which overstates CAC headroom by 8 to 18 percentage points. CM2 is the honest ceiling. CM3 (CM2 minus marketing) is the actual contribution after acquisition; that is too late to use as a ceiling.

cm2 vs cm3, what's the difference?

CM3 = CM2 minus variable marketing spend per order. CM2 is the maximum allowable CAC (the ceiling). CM3 is what's actually left after you spend on marketing — the contribution to fixed costs and profit. Both matter, for different decisions: CM2 sets the spend limit, CM3 reports the result.
