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.
Exemple Résolu
A $50,000 project with $8,000/year savings, $2,000 credits, $15,000 incentives over 20 years.
- 01Net cost: $50,000 - $15,000 = $35,000
- 02Annual return: $8,000 + $2,000 = $10,000
- 03Lifetime return: $10,000 * 20 = $200,000
- 04Net profit: $200,000 - $35,000 = $165,000
- 05ROI: $165,000 / $35,000 * 100 = 471%
- 06Payback: $35,000 / $10,000 = 3.5 years
