Most CPG brands can tell you their total revenue and their overall gross margin. Very few can tell you which channels are actually making them money and which ones are quietly destroying value. This is a problem, because the difference between a brand that scales profitably and one that grows into a cash crisis almost always comes down to channel economics.
We have rebuilt channel-level P&Ls for dozens of CPG brands, and the results are consistently surprising. The channel that looks like your growth engine on the top line is often your weakest performer on the bottom line. Let us walk through how to do this analysis properly.
Why You Need a P&L by Channel
A blended P&L hides more than it reveals. When you combine retail, DTC, and Amazon into a single income statement, profitable channels subsidize unprofitable ones, and you cannot see it. You end up making growth decisions based on revenue contribution rather than profit contribution — and those decisions compound over time.
The Single Most Important Financial Tool
The True Cost of Retail
Retail is where most CPG brands build scale, but it is also where the most costs hide. Your retail P&L needs to account for far more than the wholesale price minus COGS.

Hidden Costs Most Brands Miss
The Retail Margin Reality
The True Cost of DTC
Direct-to-consumer looks attractive on paper because you capture the full retail price. But the costs of acquiring and fulfilling DTC customers are substantial, and brands consistently underestimate them.
DTC Customer Acquisition
Fulfillment and shipping eat into DTC margins heavily. Consumers expect free or low-cost shipping. For CPG products — which are often heavy relative to their price — outbound shipping can cost $6-15 per order.
DTC Cost Breakdown (on a $30 Order)
Platform and technology costs also add up: Shopify fees, payment processing (2.6-2.9% + $0.30 per transaction), subscription management tools, email marketing platforms, and loyalty program software all reduce your DTC margin.
The DTC Profitability Threshold
The True Cost of Amazon
Amazon provides massive reach and discovery, but the fee structure is designed to capture a large share of the economics. Here is what your Amazon P&L needs to include:
Amazon Fee Stack
A typical CPG brand selling a $24.99 product on Amazon might see $6-8 in COGS, $4-5 in FBA fees, $3-4 in referral fees, $4-6 in advertising, and $1-2 in other costs — leaving $1-3 in contribution margin on a good day. That is a 4-12% margin on what looks like your fastest-growing channel.

How to Calculate True Channel Contribution Margin
For each channel, use this framework:
The Channel Contribution Formula
Advertising and paid media (channel-specific)
Fulfillment and shipping costs
Commissions and broker fees
Trade spend and promotional allowances
Platform fees and payment processing
Channel-specific labor
Do not allocate overhead, G&A, or brand marketing to individual channels. You want a clean contribution margin that tells you how much each channel contributes to covering your fixed costs and generating profit.
When to Cut a Channel
This is one of the hardest decisions in CPG, but the math should drive it. Consider cutting or reducing investment in a channel when:
Negative contribution margin
Contribution margin is negative and the trend is not improving over two or more consecutive quarters.
Disproportionate management time
The channel requires disproportionate management time relative to its contribution.
Unquantifiable brand awareness claims
You are investing in the channel for "brand awareness" but cannot quantify the halo effect on other channels.
Capital trapped in low-return inventory
Capital tied up in inventory for that channel could generate better returns if redeployed to a more profitable channel.
Think Systemically Before Cutting
Real-World Example: What This Looks Like in Practice
Consider a snack brand doing $4M in total revenue across three channels. At first glance, Amazon looks like the star — fastest growth, highest revenue. But when you build the channel P&L:
Channel P&L — Snack Brand ($4M Revenue)
Revenue vs. Contribution by Channel
Amazon generates 35% of revenue but only 15% of total contribution. DTC generates 20% of revenue but 36% of total contribution. This does not mean you kill Amazon — but it fundamentally changes how you allocate resources and where you invest your next dollar of growth capital.
The Bottom Line
Follow the Margin, Not the Revenue
The brands that win in omnichannel CPG are not the ones in the most channels. They are the ones that understand the true economics of every channel they operate in and allocate capital accordingly.
