The limitations of ROI

It doesn’t account for time period.

What is Return on Investment (ROI)?

ROI measures the gains or losses compared to the initial investment.

  • In other words, it’s an approximation of an investment’s profitability. Compared to the original investment, a positive ROI means profits, and a negative ROI = losses.

Calculating Return on Investment (ROI)

Take the current value of the investment and subtract the original investment cost.

  • Then, divide this sum by the original cost and return the investment
  • ROI = (current value – original cost) / original cost
  • Calculate ROI while taking into account the expenses.
