ROI Formula (Return on Investment)
ROI = Net Income / Cost of Investment. or. ROI = Investment Gain / Investment Base. The first version of the ROI formula (net income divided by the cost of an investment) is the most commonly used ratio. The simplest way to think about the ROI formula is taking some type of "benefit" and dividing it by the "cost".

Energy return on investment (EROI) is the ratio of energy delivered to energy costs. We examine 119 wind turbines from 50 different analyses, ranging in publication date from 1977 to 2007.
Return on Investment
x = Annualized. T = 3 years. reTherefore, (1+x) 3 – 1 = 20%. Solving for x gives us an annualized ROI of 6.2659%. This is less than Investment B''s annual return of 10%. To check if the annualized return is correct, assume the initial cost of an investment is $20. After 3 years, $20 x 1.062659 x 1.062659 x 1.062659 = $24.

Making the numbers work for a residential energy storage system
So, if a 10 kWdc residential solar system generates 12,000 kWh in a year, the customer stands to earn an additional $456/year. But, when we consider the install price of roughly $12,500 for most Tesla Powerwall systems and subtract the 30% tax credit, that leaves a 19+ year payback. This does not "pencil.".
