What is the key performance indicator (KPI) of your business? You will surely reply with the term return on investment (ROI) using an ROI calculator. 

That is right! It is the most sought-after figure for investment decision-making by business persons and individual investors. And calculating this number has become easier with an ROI calculator. 

Continue reading to get an in-depth understanding of this business basic and some reliable tools that you can use.    

What Is Return on Investment (ROI)?

What Is Return on Investment (ROI)

Return on Investment, or simply ROI is a financial formula used by businesses, investment firms, and individuals to calculate profit or loss from an investment. Additionally, financiers also use this financial metric to discover the investment efficiency of financial products like stocks, debentures, bonds, currencies, cryptocurrencies, bank deposits, etc.

Finance experts will usually express the value of ROI as a ratio or percentage. ROI is highly valued in the business ecosystem. However, the calculation has one flaw. It can not tell you anything about the investment period. It only informs you about any loss incurred or profits gained from an investment.   

What Is the Formula for ROI?

What Is the Formula for ROI

The formula for ROI calculation is quite simple. You can divide the final gain or loss with the initial financed amount. Then, multiply the result by 100 to get a percent value.

Simplified Formula

ROI = ( The Final Gain or Loss/ The Invested Value ) X 100 %

For example, you bought a stock for $100 and sold it for $150. Your final gain is $50. So, if you apply the above formula, the ROI is ( 50/100 ) X 100 %, which is 50%. 

Elaborated Formula 

ROI = {( FIV – IIV ) / IIV} X 100 %

Where, FIV is the final investment value, and IIV is the initial investment value.

Annualized ROI

Annual ROI = ROI / Period of funding in years %

Let’s consider that you had held the above equity stock for 2 years before selling it for $150. Then, the annualized ROI is 25%. The annualized value is a more meaningful ROI. Because when we talk about gains or potential gains in percentage, we usually mean it for 1 year.     

Why Do You Need an ROI Calculator?

The examples that you have found above are pretty simple. But in the real world, the investment figures, gain/loss values, and scenarios are more complex. On such occasions, you can not rely on pen and paper to calculate ROI based on the above formulas. The task will be hectic for big investment amounts and investment lengths.

To quickly get ROI values, you can use any ROI calculator. Since the formula works in the background through an algorithm, there is no chance of human or computational errors. 

Also, most ROI computing tools come with extra features and usability. For example, you can share the results online. Alternatively, you can embed the data on your website or mobile app by using a simple code provided by the tool.

Moreover, if you host any investment blogs or websites, you can embed the calculators directly on your website. You do not need to hire a paid programmer to create an ROI web app for you.
