How to Use This Calculator
  1. Enter House Sq Ft and select Insulation Level (poor, average, or good) to estimate the home's heat loss.
  2. Look up your Heating Degree Days from NOAA climate data for your location and enter the value.
  3. Enter Wood Stove Efficiency (%) — EPA-certified stoves are typically 70–80%; older stoves may be 50–60%.
  4. Set Supplemental Heat (%) if wood is not your only heat source — this reduces the firewood requirement proportionally.
  5. Review Cords Needed (one cord = 128 cu ft) and Cost Estimate to plan your wood-buying or cutting season.
  6. Use Logs to Process and Cutting/Splitting Days to schedule your firewood preparation before winter.
