CPG Gross Margin Playbook: Where Margin Leaks and How to Fix It

Gross margin depends on channel. Direct-to-consumer typically runs 60-70%, Amazon FBA 25-45%, wholesale to independent retail 25-40%, wholesale to national retail (Target/Walmart) 15-35%, national distributors (KeHE/UNFI) 10-25%, and international distributors 8-20%. Blended gross margin for a scaling CPG brand at $10M revenue with a mix of channels typically lands between 35% and 55%. The single most important number is contribution margin per channel — gross margin minus channel-specific variable costs (fulfillment, ad spend, deductions, chargebacks) — because that determines whether a channel is actually profitable to scale.

Landed cost is manufacturer cost (FOB or ex-works) plus ocean/air freight allocation per unit, plus duty (rate depends on HTS classification), plus customs broker and clearance fees, plus drayage and inbound trucking to your 3PL, plus 3PL receiving and putaway, plus tooling amortization spread over expected annual units, plus any quality control or inspection costs. For a typical overseas-sourced CPG product, landed cost runs 15-40% above the supplier PO price. Brands that quote gross margin from supplier PO price are typically overstating margin by 5-10 percentage points.

Deductions are amounts retailers or distributors subtract from your invoices before paying — for things like promotional pricing (MCB), routing-guide violations, OTIF penalties, damages and shortages, slotting amortization, coop and MDF programs, free-fill, and historical post-audit adjustments. For a scaling wholesale brand, deductions typically consume 8-18% of gross wholesale revenue. Most brands never disaggregate deductions by category, so they cannot see which retailer, which operational failure, or which promotional program is actually the leak. The disaggregation exercise — coding 12 months of remittance detail into categories — is the first step in any margin recovery.

DIM weight optimization typically recovers 8-20% of parcel freight spend for CPG brands. The mechanism: parcel carriers price the larger of actual weight and dimensional weight (L × W × H / divisor). Most brands ship in 3-5 standard box sizes when 8-12 would fit product more tightly. Right-sizing boxes and replacing void fill (air pillows, paper) with die-cut inserts or tighter packouts reduces DIM weight without increasing damage rate. On a brand doing $1M/year in parcel freight, that is $80K-200K/year recovered. The engagement to implement typically runs 60-90 days.

Gross margin is net revenue minus COGS (product plus inbound freight). Contribution margin is gross margin minus channel-variable costs: outbound freight, fulfillment, ad spend, promotional deductions, chargebacks. Contribution margin is the number that determines whether a channel is actually profitable to scale. A brand can have 45% Amazon FBA gross margin and negative contribution margin after PPC ad spend; a brand can have 22% distributor gross margin and healthy contribution margin because chargebacks are low and freight scales down. Investors and lenders increasingly look at contribution margin by channel rather than blended gross, because it tells them where growth is actually creating value.

MCB (Manufacturer Chargeback) is the mechanism for running promotions through a distributor. You publish a promotional price on a KeHE bulletin or UNFI E-Note; the distributor bills you back the discount on cases sold at the promotional price. Typical MCB runs $1-3 per case for run-rate promotions. Managing MCB well requires: (1) a trade-spend calendar with pre-committed budget per account, (2) verification of MCB against actual case-count reports from the distributor before accepting the deduction, (3) 60-day post-promo ROI review, and (4) killing or renegotiating promotions that fail to lift velocity 20%+. Unreconciled and unchallenged MCB is one of the most common margin leaks for growing wholesale brands.

Every 18-24 months. Rates rise on contract renewals and never come back down without pressure. A rebid typically recovers 5-15% on pick-pack fees and 3-8% on storage, even when you stay with the incumbent. The rebid process itself takes 8-12 weeks: pull 6 months of activity data (orders, units, storage, receipts), issue an RFP to 3-5 3PLs, evaluate on pricing, service, tech integration, and geography, and negotiate. Even brands that stay with the incumbent gain leverage on the renewal terms.

OTIF (On-Time In-Full) is the retailer measurement of whether your shipments arrive at the appointed window with the full quantity ordered. Walmart, Target, Kroger, and others charge back a percentage of the shipment value for OTIF failures — typically 3% of the shipment for late, plus 3% for short. Prevention requires: (1) production and inventory planning that keeps safety stock at retailer-specific coverage levels, (2) automated ASN generation triggered by pack list, filed within the required window, (3) 3PL SLAs that make the 3PL responsible for on-window carrier pickup, and (4) monthly OTIF scorecard review with root-cause coding for every failure. Brands that hit sustained OTIF above 95% typically pay less than 0.5% of gross in OTIF chargebacks; brands running 85-90% OTIF often pay 3-5%.
