Lumper Cost Calculator — Freight Unloading Cost Per Load
Calculate lumper cost per load and annual unloading expense. Compare third-party lumper services vs driver unload and quantify the full cost of dock unloading.
💪 Lumper Cost Calculator
How to Use This Calculator
- Enter loads per month requiring lumper — loads where you use third-party unloading labour.
- Enter base rate and pallet count structure — most lumper services charge a base for 20 pallets then a per-pallet rate above that threshold.
- Include overtime — after-hours and weekend unloading typically carries a $50–$150 premium.
Worked Example
80 loads/month, 22 avg pallets, $200 base (20 included), $4.50/extra pallet, 15% OT at $75.
- Base: $200
- Extra 2 pallets: $9
- OT: $11.25
- Avg/load: $220.25
- Annual: $211,440
Lumper receipts should be collected on every load and audited against invoices monthly — lumper billing errors and duplicate charges are common and often go unnoticed.
Frequently Asked Questions
Lumpers are third-party labour hired to unload trailers at retail DCs or grocery warehouses. Many retailers (Walmart, Kroger, Target) require all inbound loads to use their approved lumper service. Carriers are not legally required to unload, so lumper cost falls to the shipper or is negotiated into freight rates.
Yes — if you deliver to accounts that require lumper service, include estimated lumper cost in your pricing. Many shippers exclude it accidentally, creating a margin leak. Track lumper expense as a separate line item and include in total cost-to-serve by customer.
