What Your Result Means

How This Calculator Works

You enter the number of cords you need and the local price per cord. The tool multiplies cords by standard conversion factors: roughly 1,000 logs, 2.7 tons, and 18 hours of burn time per cord. It assumes mixed seasoned hardwood at moderate moisture. It does not account for wood species, split size, or stove efficiency differences.

Quick Questions

What is the difference between a cord and a face cord?

A full cord measures 4 × 4 × 8 feet (128 cubic feet). A face cord is the same height and width but only one row of logs deep, typically about one-third of a full cord.

How much firewood do I need for a winter?

Most homes using a wood stove as a primary heat source burn 3–5 cords per winter in cold climates. Occasional fireplace use might only need 1–2 cords per season.

Does wood species affect burn time?

Yes, significantly. Dense hardwoods like oak and hickory burn much longer per cord than softwoods like pine or spruce. The calculator uses an average for mixed seasoned hardwood.

How long should firewood be seasoned?

Most firewood should be seasoned (air-dried) for 6–12 months to reach about 20% moisture content. Burning green wood produces more smoke, less heat, and more creosote buildup.
