Calculator Inputs and Outputs
Inputs
- Heated home area (ft²) — example: 1800
- Cords per 1,000 ft² per month — example: 0.45
- Heating months — example: 5
- Reserve allowance (%) — example: 15
Results
- Estimated firewood (cords)
- Stacked volume (ft³)
- Base estimate before reserve (cords)
Formula used
Cords = home area/1,000 × monthly cord rate × months × reserve factor.
