Environmental ROI Calculator — Formula
## How to Calculate Environmental ROI
Environmental ROI measures the financial return from green investments.
### Formula
**Net Cost = Investment - Incentives**
**Lifetime Return = (Annual Savings + Credits) * Years**
**ROI = (Lifetime Return - Net Cost) / Net Cost * 100**
Many green projects have excellent ROI when including energy savings, carbon credits, tax incentives, and avoided regulatory costs.

Esempio Risolto
A $50,000 project with $8,000/year savings, $2,000 credits, $15,000 incentives over 20 years.
- Net cost: $50,000 - $15,000 = $35,000
- Annual return: $8,000 + $2,000 = $10,000
- Lifetime return: $10,000 * 20 = $200,000
- Net profit: $200,000 - $35,000 = $165,000
- ROI: $165,000 / $35,000 * 100 = 471%
- Payback: $35,000 / $10,000 = 3.5 years
