3PL storage fees: per pallet vs. per bin vs. per cubic foot (and per square foot or location)

Why you can't compare storage rates across units#

Storage rates in different units can't be compared directly: a pallet rate charges for every position however full, a cubic-foot rate for the volume of goods. At The Fulfillment Advisor's 2026 survey averages, $19.37 per pallet and $0.45 per cubic foot¹, which is cheaper depends on how full your pallets are and how each quote counts inventory.

For most DTC brands, postage is the largest part of 3PL spend and storage is often the smallest major line. But among charges billed every month whether or not you ship, storage is one of the largest, and a common place for billing errors: rates that drift above contract, counts that don't match your records, and inflated dimensions.

How 3PLs price storage#

3PLs price storage per pallet position, bin or shelf, cubic foot, square foot, storage location or, in B2B warehouses, per package¹¹, often combining units. Shares of Implentio customers' 3PL contracts with storage charges, mostly for DTC brands (last two rows: where invoices show the unit):

Per pallet (pallet position)#

Per-pallet pricing charges a monthly rate for each pallet position (one rack or floor slot sized for one pallet), full or half empty^2,9. Half-pallet rates are uncommon, so this unit favors full pallets of a few SKUs. One 2014 pricing guide builds honeycombing, space lost to partly filled pallets, into its rate¹⁶.

The rate card defines a pallet by footprint (48 × 40 in is the US standard¹⁵) and loaded height. Caps commonly fall between 48 and 60 in, with about 55 in common at ecommerce 3PLs; check whether the cap includes the pallet itself. Over-cap pallets are billed as two positions⁵, at a tall-pallet rate⁶ or per cubic foot¹³. Public companies file some of their contracts with the U.S. Securities and Exchange Commission (SEC), which publishes them, so a few 3PL contracts can be read in full; the per-cubic-foot example comes from one of them¹³.

Many ecommerce 3PLs require one SKU per location^4,5, so a mixed pallet is broken down or billed as one position per SKU. Consolidating partial pallets is often negotiable, sometimes for a labor charge. See Partial pallets and rounding: how 3PLs count a "pallet" and Pallet height and weight standards and oversize pallet charges.

Per bin or shelf#

Per-bin pricing charges a monthly rate for each bin (a small container or shelf slot for low-quantity SKUs) or shelf (a larger slot) you occupy. Sizes aren't standardized: one 3PL's published card (September 2026) charges $3 a month for a 0.55 cu ft bin, $5 for 2 cu ft and $20 for a 15 cu ft shelf⁵. About a quarter of Implentio customers' 3PL contracts with bin storage use size tiers. Without dimensions, per-bin rates can't be compared. Under a one-SKU-per-location rule, bin, shelf and pallet charges grow with SKU count.

Per cubic foot#

cubic foot storage charges for the volume your goods take up, almost always the item or carton dims in the 3PL's warehouse management system (WMS) times quantity on hand, not the location's size^7,9. Some fulfillment networks bill this way^2,7,9, as does Amazon FBA, which is not a 3PL¹⁴.

Cubic feet = (length × width × height, in inches) ÷ 1,728

Monthly charge = cubic feet per unit or carton × quantity on hand × rate

WMS dims are more often too big than too small (rounded up, case dims on single units, mixed-up units of measure), and an inflated dim overcharges monthly until fixed. See Why accurate product weights and dims drive everything downstream.

As of October 2026, one large fulfillment network bills each SKU the greater of its cubic charge or $0.10 a day⁷, about $3 a month (derived), up from $0.01 before February 5, 2026⁸.

Per square foot#

Square-foot storage is a fixed rate for an area allocated to you, full or not¹⁷. It appears more in dedicated space and contract warehousing than in DTC fulfillment¹⁰. Quoted square footage often includes aisles and shared areas. One 2014 rate build counts 20.8 sq ft per floor position, including half the aisle¹⁶, about 1.56 times a 48 × 40 in pallet's 13.3 sq ft (derived), so ask for the layout behind the number.

Per storage location#

Per-location pricing charges for each storage slot your inventory occupies¹⁰, with a price for each slot type⁵. Location count depends on slotting, the 3PL's assignment of SKUs to pick and reserve (backup) locations, which can reflect velocity (ABC class: A fast, C slow). IWLA's standard terms for merchandise warehouses (2026 revision) also allow a minimum storage charge per lot per month¹¹.

Whether lots (batches) share a location depends on the 3PL's system and rules. Where each lot or expiry date gets its own pick location, for FEFO (first expired, first out) picking and recalls, one SKU with three live lots can take three locations. Some 3PLs mix lots in reserve storage and separate them only at the pick face.

A SKU can also hold stock in a pick location and in reserve at the same time; under per-location or per-pallet pricing, each occupied location is billed. Few 3PLs move a SKU to a smaller location on their own as it sells down; brands usually have to ask, and some 3PLs charge labor for the move. See Bin vs. pallet migration: when moving inventory saves money.

When the count is taken#

A storage count can be a one-day snapshot, a daily average⁹, a peak, or prorated by the day or half month^3,11, and some 3PLs also charge on receipt. The count method can change the bill as much as the storage unit does (compare the count rows in the worked example below); for how each method treats arrivals and departures, see How storage is measured: snapshot, average, peak or billing-day count.

Fees to keep separate from storage#

Pallet in/out and receiving fees are charged per movement, not per period, under receiving, putaway, pallet pick or accessorial lines. If storage counts toward a monthly minimum, savings that take eligible fees below the floor come back as a shortfall charge; whether storage counts depends on the clause.

About 30% of Implentio customers' 3PL contracts with storage charges also bill quarantine, returns, dock overstay or overflow storage separately, while aged-stock surcharges rarely appear on those invoices as their own line. In The Fulfillment Advisor's 2026 survey of 500 warehousing and fulfillment providers, 41% charged long-term storage fees¹, so check the contract for one. See Long-term storage surcharges and aged-inventory fees and Hazmat, temperature-controlled and secure-cage storage premiums.

Side-by-side comparison: which method fits your inventory#

Pallets fit few SKUs on full pallets; bins and cubic foot fit small or partial ones.

For lot- or expiry-controlled products, test cubic pricing or location pricing with a lot consolidation rule; for seasonal build-ups, favor daily-average or prorated counts.

The break-even rule: when pallet pricing beats cubic-foot pricing#

Per-pallet pricing beats cubic-foot pricing when each pallet holds more cubic feet of goods than the pallet rate divided by the cubic-foot rate. The rule holds if both rates come from one rate set, count inventory the same way and carry no per-SKU minimum:

Break-even cubic feet per pallet = pallet rate ÷ cubic-foot rate

At the 2026 survey averages, $19.37 ÷ $0.45 = 43.0 cu ft¹.

Break-even fill rate = break-even cubic feet ÷ pallet capacity in cubic feet

A 48 × 40 in pallet stacked 48 in high holds 92,160 ÷ 1,728 = 53.3 cu ft, so break-even is about 81% full (43.0 ÷ 53.3); stacked 60 in high (66.7 cu ft), about 65%. For bins, $3.03 ÷ $0.45 = 6.7 cu ft, more than the bins on one published card hold (0.55 to 2 cu ft⁵), so at 2026 survey averages cubic beats any bin up to 6.7 cu ft, absent a per-SKU minimum.

What good looks like#

Good storage terms let you rebuild the bill. The contract states each "Get in writing" item, the count method and day, proration and rounding, and reports show the quantity and unit behind every line. Judge a rate against the right population:

• Ecommerce fulfillment 3PLs that publish rates list about $30–$45 per pallet a month as of October 2026^3,5,6.
• B2B and contract warehouses often charge $10–$25^12,13, and less at high volume¹⁸.
• Survey averages can include both: $19.37 per pallet a month in The Fulfillment Advisor's 2026 survey of 500 warehousing and fulfillment providers¹.
