Drop Trailer Pool Fee Calculator
Cost a drop-and-hook trailer pool: daily trailer rent past free days versus the live-unload detention it replaces.
Set a tier's days to 0 to mean “all remaining days”.
Drop programs trade hourly detention for daily trailer dwell charges — cheap per day, expensive when trailers become free warehousing across a network.
With your numbers: 9 days − 2 free = 7 chargeable days = 5×$20 + 2×$35 = $170 per trailer × 4 = $680.

Demurrage, detention and storage tariffs are set by each carrier, terminal and contract and change frequently. The preloaded figures are editable industry-typical examples, not quotes — always verify against the current published tariff or your service contract before paying or disputing an invoice.

Drop-and-hook solves detention by leaving the trailer — and creates a slower, quieter charge in its place: trailer dwell. Carriers running drop pools bill daily fees when trailers sit loaded (or empty and unreleased) past an allowance, typically a couple of free days then $15–$40 per trailer-day. Cheap next to $65/hr detention, which is exactly why trailers quietly become warehouses.
About Drop Trailer Pool Fee Calculator
The defaults model a 4-trailer pool where units sit 9 days against 2 free — the per-trailer math is small, the fleet math isn't. Multiply across a season and a shipper 'saving' detention can fund the carrier's trailer purchases. Pool right-sizing — trailers matched to actual weekly throughput — is the entire game. Audit both sides if you're the carrier: dwell fees only collect when trailer telematics or yard checks actually record where units sit (a trailer 'lost' at a consignee for three weeks is a write-off, not a fee). And if you're the shipper, treat the dwell invoice as a free utilization report — it tells you which docks turn trailers and which hoard them.

Frequently asked questions
What's a typical drop trailer free time and daily rate?+
Two to three free days, then $15–$40 per trailer per day is the common band, sometimes tiering up after a week. The rate sits deliberately below warehouse pallet pricing until it doesn't — the second tier exists because at some point the carrier must buy another trailer to cover the one you're storing freight in.
Is drop-and-hook always cheaper than live unload?+
Per stop, usually: no detention exposure, faster driver turns, better HOS utilization. Per network, only if trailers cycle. The crossover is calculable: live unload risk (detention hours × rate × frequency) versus pool cost (trailers × dwell days × daily fee). This calculator gives the right side; your detention history gives the left.
How many trailers should a drop pool have?+
Weekly volume ÷ realistic trailer turns per week, plus a small buffer. A dock that unloads drops within 2 days turns a trailer ~3×/week; 30 loads needs ~10–12 trailers, not 20. Pools sized to peak week instead of typical week are where dwell fees breed — the calculator's fleet quantity field models exactly that overage.
Who pays dwell when the consignee won't release the trailer?+
Contractually the shipper (the carrier's customer), who then has the leverage problem with their consignee — carriers bill whoever signed the rate agreement. Shippers with chronic slow receivers increasingly pass dwell through in their customer terms, which converts an absorbed cost into a behaviour signal.
