Every investor does investments with the sole purpose of earning higher returns and maximizing their wealth. The returns generated on the investment vary based on various factors like the type of investment, its volatility, the degree of risk involved, the demand of the investment product, its liquidity, etc. While starting an investment, we always hear about the approximate or exact percentage of returns it can generate over a period of time. However, what it means in actual terms is what matters to the investors ultimately. For this, investors have to understand the meaning of the term return on investment and its formula at the same time the use of calculators to effectively calculate the same.

What is the return on investment?

Return on investment is a financial ratio or a metric used to measure the returns generated by investment and its value. It can also be used as an effective tool to compare an investment in terms of returns with other investments to choose between two or more competing investment options. This is quite helpful in situations where the cost of the investment may be similar and the returns can determine which is a better investment option for the investors. ROI can be used effectively to measure returns generated by fixed-income investments or investments that may not provide consistent returns. 

What is the formula to calculate return on investment?

ROI is the measurement or the ratio between the net profits or returns from an investment and the total initial investment or the cost of investment. ROI can be measured in the following ways

  • Annualized returns 

The formula to calculate ROI based on annualized returns is,

ROI = [(End value of investment/ Initial value of investment) ^ (1/n)] – 1.

This is a better way of comparing investment as it accounts for the time factor or the period of investment which is crucial for evaluating the overall performance of an investment.

The net income method is the basic computation of ROI where the net value generated at the end of the investment is compared to the cost of investment and represented in the form of a percentage. According to this method, 

ROI = (Net income or gains from investment/ Cost of investment) * 100

  • Capital gains method 

This is an elaborate version of the net income method to calculate ROI. The formula to calculate ROI as per the capital gains method is mentioned below.

ROI = [Final value of investment – Initial value of investment)/Cost of investment]*100

What is the return on investment calculator?
