3PL Cost Analysis for CPG Brands: How to Evaluate and Reduce Third-Party Logistics Costs
Third-party logistics costs are one of the most opaque line items in a CPG brand's P&L. Here is how to understand what you are actually paying and whether you are getting a fair deal.
Third-party logistics (3PL) providers handle warehousing, fulfillment, and often transportation for CPG brands that do not operate their own distribution infrastructure. 3PL costs are typically 5–12% of revenue for CPG brands, but many brands do not fully understand what they are paying or whether their 3PL is cost-competitive.
The Anatomy of a 3PL Invoice
| Fee Type | How It Is Charged | Typical Rate |
|---|---|---|
| Inbound receiving | Per pallet or per hour | $8–$25/pallet or $35–$65/hour |
| Storage | Per pallet per month | $12–$35/pallet/month |
| Pick and pack (each) | Per unit picked | $0.50–$2.50/unit |
| Pick and pack (case) | Per case picked | $1.50–$5.00/case |
| Outbound freight (small parcel) | Per shipment + weight | Carrier rate + 5–15% markup |
| Outbound freight (LTL/FTL) | Per shipment | Carrier rate + 5–15% markup |
| Returns processing | Per unit or per hour | $2–$8/unit |
| Account management | Monthly flat fee | $200–$1,000/month |
How to Calculate Your True 3PL Cost Per Unit
3PL Cost per Unit = (Total Monthly 3PL Invoice) / (Units Shipped per Month)
Or by component: Storage Cost per Unit + Pick Cost per Unit + Outbound Freight per Unit
The storage component is often overlooked. If you hold 200 pallets at $20/pallet/month and ship 5,000 units/month, your storage cost is $4,000/month = $0.80/unit — before any pick or freight costs. Slow-moving SKUs with high storage costs can have 3PL costs that exceed their contribution margin.
When to Evaluate Switching 3PLs
The 3PL market is competitive, and rates vary significantly between providers. You should get competitive quotes from at least 2–3 3PLs every 2–3 years, or when your volume grows significantly (volume discounts kick in at different thresholds). Key triggers for evaluation: your 3PL has raised rates more than 10% in a year, your error rate (wrong items shipped, damaged goods) exceeds 0.5%, or your storage costs are growing faster than your revenue.
Frequently Asked Questions
Should 3PL costs be included in COGS or operating expenses?
It depends on the type of cost. Inbound freight and receiving (getting product into the warehouse) is typically included in COGS as part of landed cost. Storage costs are typically classified as operating expenses (cost of goods available for sale). Outbound fulfillment costs (pick, pack, outbound freight) are typically classified as selling expenses. The key is consistency — choose a treatment and apply it consistently for meaningful period-over-period comparison.
What is a reasonable 3PL cost as a percentage of revenue?
For DTC-heavy brands, 3PL costs of 8–12% of revenue are typical (parcel fulfillment is expensive). For wholesale-heavy brands, 3–6% is more typical (case-level fulfillment is much cheaper per unit than each-level). If your 3PL costs exceed 12% of revenue, it is worth a detailed analysis to identify whether the issue is pricing, product mix, or operational inefficiency.
