payload
PAY-lohd
/ˈpeɪ.loʊd/
The revenue-producing part of a load carried by a commercial truck, aircraft, or vessel.
Refers specifically to carrying capacity that generates revenue, excluding fuel, vehicle weight, and driver.
The story behind the word. Coined during early commercial aviation and trucking in the 1930s to distinguish between the structural weight of the transport craft and the portion of the load that actually 'paid' income.
Word relationships
- net load: Net load is a strictly weight-focused term, whereas payload carries strong commercial value implications.
- freight load: Freight load is descriptive, while payload specifies total potential capacity.
- tare weight: Tare weight is the weight of the empty vehicle alone without any cargo or occupants.
Commonly confused with
- gross weight: Gross weight combines both the empty vehicle weight and the payload together.
Word family
- payloads (noun): Plural form for multiple cargo capacities or loads.

Memory hook
PAY-LOAD: The portion of the LOAD that pays your salary! Cargo weight that pays.
When not to use
Do not use 'payload' to include the tare (empty) weight of the truck itself.
Fun facts
- Space travel adopted 'payload' directly from freight trucking to describe satellites or experiments placed aboard rockets.
