Return on Investment (ROI): Meaning, Formula, Benefits & Limitations

Return on Investment (ROI) is the best financial term. It is used to represent the efficiency of an investment. Sometimes it is referred to as Return on Costs (ROC). It may be a positive ROI of an investment, representing the financial value generated more than its cost. And also, it may be a negative ROI of an investment, representing that the financial value generated is less than its cost. The calculation is based on

• Investment duration,
• Risk tolerance and
• Industry norms.

It allows investors and businesses to compare different opportunities on an equal footing. And measures how much net profit (or loss) is generated relative to the initial cost. A positive ROI indicates profit on investment. The negative ROI  indicates a net loss.

The Return on Investment determines the viability of various ventures listed as below

• Stocks,
• Corporate finance,
• Mutual funds,
• Real estate investments,
• Capital budgeting,
• Internal business projects like marketing campaigns,
• Personal investing.

ROI always brings the best clarity to financial decision-making with data-driven results. It expresses the gain or loss generated on an investment relative to its cost, shown as a percentage.

Formula for Return on Investment Calculation

The ROI is always expressed as a percentage. The basic standard formula for ROI calculation as follows:

 ROI =   The net profit  (Current Value – Initial Investment) / The cost of the investment x 100                       

That is (Net Gain from Investment ÷ Cost of Investment) × 100.

The ROI value will be arrived by dividing the net profit by the cost of the investment, and then multiplying with 100. The end result will be in a percentage.

Limitations of Return on Investment

Fails to Adjust for Inflation

The ROI does not consider the time factor of money and fails to adjust for inflation. It actually reduces the real value of money over time. And also it fails to adjust for the opportunity cost of putting the capital elsewhere. It is not at all bothered about the time value of money.

Ignore the Hidden Costs

It ignores the hidden costs like processing fees, stamp duty, and taxes. It will always end with a lower actual return than the calculated percentage.

Disregard the Time Factor

Standard Return on Investment  ignores the holding period of an investment. That is the duration an investment. A 30% ROI earned over 1 year is far superior to a 30% ROI earned over 5 years, yet the basic formula treats them as identical.

Poor Account for the Risk Level

The major focus of ROI is on financial return, and it fails to consider the risk level in a project. It doesn’t provide a clue about the probability of total capital loss. It is a major problem with high ROI figures. The impact of the lack of risk consideration is great. 

Lacks Focus On Future Results

The Return on Investment  is of a backward-looking nature. It always measures past performance. And it does not necessarily indicate future results. It lacks focus on future results, and it is a major limitation in dynamic markets.

Encourages Managers Myopia

The ROI leads managers to focus heavily on short-term, high-ROI projects. It spoils the attention on the long-term and strategic investments. 

Need the Support of Other Metrics to Get a Fuller Picture

Because of its limitations, professional investors consider other metrics for supporting purposes. And they rarely rely on ROI alone. They use it alongside the following metrics to get a fuller picture:

1. Net Present Value (NPV) – The NPV accounts for the time value of money. It is with respect to future cash flows to their present value.
2. IRR (Internal Rate of Return) – It is helpful to determine the interest rate at which the NPV of all cash flows equals zero. It is the best for long-term planning. The advantage is it considers the time value of money.
3. Payback Period – The payback period calculates the time taken to recover the initial investment cost. And a shorter period is always preferred.
4. Rate of Return (RoR) – The RoR is a totally time-based one. It measures gain or loss over a defined time frame. It will be helpful to offset ROI’s time-blindness.

Problem of Non-Standardization and Vulnerability

The ROI calculation is not following a rigid standard procedure. Sometimes it includes overhead costs. And sometimes it might not include overhead costs. It will lead to different results for the same investment. The problem of vulnerability for what must be included in “profit” or “cost” is heavy.
