DTC vs. Wholesale: How to Track Profitability by Channel

Most CPG founders can tell you their overall gross margin. Far fewer can tell you their gross margin by channel. And almost none can tell you their contribution margin by channel — the profit left after accounting for every cost specific to selling through that particular path to market.

This blind spot leads to some of the most expensive strategic mistakes in CPG: pouring money into a channel that looks profitable on the surface but is actually destroying margin once you account for all the associated costs. The fix is building a channel-level P&L — a financial view that shows you exactly how much each channel contributes to your bottom line after all channel-specific costs are deducted.

A blended P&L tells you whether your business is profitable in aggregate. A channel-level P&L tells you why it is or is not profitable, and where to focus your resources.

Consider a brand doing $2 million in revenue: $800K from DTC, $900K from wholesale, and $300K from Amazon. The blended gross margin is 42%. Solid. But when you break it down by channel, the picture changes dramatically.

The structure is the same for each channel: start with revenue, subtract COGS, subtract channel-specific costs, and arrive at a contribution margin. The challenge is accurately assigning costs to the right channel.

Direct-to-consumer channels offer the highest gross margins in CPG but carry significant costs that chip away at that advantage.

Customer Acquisition Cost (CAC) is the total you spend on paid social, search ads, influencer partnerships, and other marketing to acquire a new customer. For CPG brands, CAC typically ranges from $15 to $50 per new customer. If your average order value is $35, a $30 CAC means you are losing money on the first order and betting on repeat purchases to reach profitability.

Fulfillment and shipping for individual orders is far more expensive per unit than palletized shipments to retailers. Expect $4 to $8 per order for fulfillment, plus $5 to $12 for shipping depending on weight and zone. If you offer free shipping, this cost comes directly out of your margin.

Platform and transaction fees from Shopify ($79-$399/month plus 2.4-2.9% per transaction) and subscription platforms like Recharge add up to 3-5% of DTC revenue.

Returns and replacements for DTC CPG are lower than apparel, but damaged shipments and customer service replacements still occur. Budget 2-4% of DTC revenue.

Wholesale looks simple — ship pallets, receive payment. In reality, the cost structure is layered and often opaque.

Trade spend and promotional allowances are usually the single largest channel-specific cost in wholesale. Slotting fees, temporary price reductions (TPRs), off-invoice discounts, and scan-based promotions can consume 15-30% of gross wholesale revenue. If you are not tracking trade spend as a percentage of gross revenue by retailer, you are flying blind.

Broker commissions of 3-7% of net sales are standard if you use a broker or sales agency. Some brokers also charge monthly retainers or per-store fees for merchandising and demos.

Deductions and chargebacks beyond trade spend include compliance violations, shortages, and damaged goods. Budget 1-3% of gross wholesale revenue for unplanned deductions.

Freight and logistics to retailer distribution centers, including fuel surcharges, lumper fees, and routing charges, typically run 5-10% of wholesale revenue.

Amazon is its own ecosystem with a unique and often punishing cost structure.

Referral fees take 8-15% of the sale price depending on category. For grocery and gourmet food, it is typically 8% on items over $15 and 15% on items under $15.

FBA fees for a standard-size CPG product typically run $3 to $6 per unit, plus monthly storage fees. Long-term storage fees (for inventory sitting more than 180 days) add significantly to this.

Coupons and Subscribe & Save discounts, Lightning Deals, and other Amazon promotions are all funded by the seller. Subscribe & Save alone typically costs 5-10% of the item price.

Returns under Amazon's generous return policy mean CPG brands see return rates of 2-5%, and returned food products are almost never resellable.

Beyond channel-specific costs, your business has overhead that supports all channels: office rent, executive salaries, accounting fees, ERP software, and general insurance. The question is how to allocate these costs across channels to arrive at a fully loaded profitability picture.

Revenue-weighted allocation distributes overhead proportionally based on each channel's share of total revenue. Simple and directionally accurate for most brands.

Activity-based allocation assigns overhead based on the actual resources each channel consumes. If your team spends 50% of their time managing Amazon, Amazon gets 50% of the salary allocation regardless of its revenue share. More accurate but requires time tracking.

The goal of a channel P&L is not accounting precision — it is strategic clarity. Even a directionally accurate channel P&L is infinitely more useful than a blended P&L that hides underperforming channels behind strong ones.

Once you have channel-level P&Ls, the strategic decisions become clearer. Here is how to think about the most common scenarios:

When DTC Has High Revenue but Low Contribution Margin

This usually means your CAC is too high relative to your average order value and repeat purchase rate. Before scaling back DTC, analyze your customer cohort data. If customers who survive past their second purchase have strong lifetime value, the issue is not the channel — it is your acquisition targeting or retention strategy. If repeat rates are low across the board, you may need to rethink whether DTC is a viable primary channel for your product category.

When Wholesale Revenue Is Growing but Margins Are Shrinking

This often signals that trade spend is outpacing revenue growth. Review your promotional calendar and trade rates by retailer. Some retailers may be demanding more aggressive TPRs or higher slotting fees than the volume justifies. It may be time to reduce promotional frequency with underperforming accounts or renegotiate trade terms.

When Amazon Looks Profitable Until You Add Back Advertising

This is extremely common. Amazon can generate positive contribution margin if you have organic search dominance and strong reviews, but most brands are spending heavily on PPC to maintain ranking.

How to Think About Channel Expansion

When evaluating a new channel, model the full cost structure before committing. A new retail partnership might seem like a huge revenue opportunity, but once you account for slotting fees, initial trade spend, broker commissions, and the working capital required to fund 45 to 60 days of receivables, the first-year economics might be negative. That can still be a good investment if you project profitability by year two — but you should go in with eyes open.

Building channel-level P&Ls is not a one-time exercise. Update them quarterly at minimum, monthly if you can. As your channel mix evolves, the cost structures will shift. Trade spend rates change. CAC fluctuates with the advertising market. Amazon fees increase. The brands that review these numbers regularly can adjust their strategies proactively rather than discovering margin problems after the damage is done.
