Compost Volume Calculator — Formula
## How to Calculate Compost Volume
Composting reduces organic waste volume by 50-75% while producing nutrient-rich soil amendment.
### Formula
**Finished Compost = Input Volume * (1 - Reduction %)**
### Volume Reduction
- Hot composting: 60-75% reduction
- Cold composting: 50-65% reduction
- Vermicomposting: 70-80% reduction
Composting diverts 30-40% of household waste from landfills.

Exemplo Resolvido
5 gal kitchen scraps and 10 gal yard waste weekly for 52 weeks with 65% volume reduction.
- Total input: (5 + 10) * 52 = 780 gallons
- Finished compost: 780 * (1 - 0.65) = 273 gallons
- In cubic feet: 273 / 7.48 = 36.5 cu ft
- CO2 avoided: 780 * 0.005 = 3.9 metric tons
