Estimating firewood needs for a winter season depends heavily on how the fireplace or wood stove is actually used — as a primary heat source running most of the day versus occasional supplemental warmth on especially cold evenings.
This calculator applies rough, commonly cited estimates: a home using wood as its primary heat source through a full season typically burns somewhere around 3-5 cords, while supplemental or occasional use burns considerably less, scaled here based on your estimated daily burning hours and season length.
Actual firewood consumption varies significantly based on climate, home insulation, stove or fireplace efficiency, and wood type, so treat this as a rough planning estimate — many people find it useful to track actual usage in their first season and adjust future purchases accordingly.

Frequently asked questions
What's a cord of firewood?
A standard cord is a stacked pile measuring 4 feet by 4 feet by 8 feet, totaling 128 cubic feet, though actual solid wood volume within that stack (accounting for gaps) is somewhat less.
Does wood type affect how long a cord lasts?
Yes, denser hardwoods like oak or hickory burn longer and produce more heat per cord than lighter softwoods, so wood species affects how far your firewood supply stretches through the season.
