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.

计算示例

A $50,000 project with $8,000/year savings, $2,000 credits, $15,000 incentives over 20 years.

  1. Net cost: $50,000 - $15,000 = $35,000
  2. Annual return: $8,000 + $2,000 = $10,000
  3. Lifetime return: $10,000 * 20 = $200,000
  4. Net profit: $200,000 - $35,000 = $165,000
  5. ROI: $165,000 / $35,000 * 100 = 471%
  6. Payback: $35,000 / $10,000 = 3.5 years
