- Cord
- The standard unit of firewood volume — a stack measuring 4 feet high × 4 feet wide × 8 feet long, totaling 128 cubic feet.
- Face Cord
- A stack of firewood 4 feet high × 8 feet long but only as deep as the individual log length, typically 16 inches — roughly one-third of a full cord.
- Seasoning
- The process of drying cut firewood to reduce moisture content, typically to below 20%, so it burns efficiently with less smoke.
- Moisture Content
- The percentage of water weight relative to total wood weight — firewood under 20% moisture is considered ready to burn.
- Log Processor
- A machine that simultaneously splits and cuts logs to length, dramatically increasing throughput compared to manual splitting.
- Delivered Price
- The all-in price charged to a customer including wood cost, splitting, loading, transport, and stacking — the primary retail pricing unit.
- Species Mix
- The combination of wood species in a firewood supply — hardwoods like oak and hickory burn longer and hotter than softwoods like pine.
- Burn Rate (Operational)
- Monthly cash outflow for ongoing operating costs — equipment fuel, labor, insurance, and vehicle maintenance — before revenue is collected.
- Seasonality
- The predictable fluctuation in firewood demand across months — peak demand runs October through February in northern climates, with sharp drop-offs in spring.
- Wood Lot
- A parcel of forested land managed as a source of timber or firewood, either owned outright or harvested under a cutting agreement.
