Firewood Calculator – Calculate Firewood Amount Needed for Heating Season
Firewood calculator determines how many cords or cubic meters of firewood you need for the winter heating season based on home size, insulation level, and wood type. The tool also shows estimated cost.
Enter your home's heated square footage, heating method (fireplace, wood stove, furnace, central heating), and wood species, and the calculator estimates required wood amount. Oak and maple have the highest heat value, while pine and poplar dry fastest.
How much firewood is used in winter?
A well-insulated 1,000 sq ft home uses about 3-5 cords of firewood as primary heating per winter. A fireplace for supplemental heating uses about 1-2 cords. One cord of seasoned oak equals approximately 20-25 million BTUs. Dry wood (moisture below 20%) burns much more efficiently than green wood.

Enter house size, insulation level, and heating method, and the calculator estimates firewood needs for the heating season.
- Estimate firewood needs in cubic meters or loose cubic meters.
- Account for house size and insulation level's impact on consumption.
- Compare different wood species' heat values and consumption.
Firewood consumption varies significantly based on winter severity and heating habits.
- Dry birch produces more heat than coniferous wood – wood species affects consumption.
- Wood moisture content directly affects heat value – dry wood is most efficient.
- Fireplace and stove models differ significantly in efficiency.
Proper drying and storage of firewood are key to efficient heating.
- Firewood should be dried 1–2 years before use – fresh wood burns poorly.
- Loose cubic meter and stacked cubic meter are different – check unit when ordering.
- The calculator provides an estimate – actual consumption depends on winter and heating method.
