Difference Between IRR and ROI

IRR vs. ROI

When can you tell that your stocks, and or capital, have actually returned? When can you say that your company has actually generated gains amidst every expenditure and cost of operation? For answers to these particular queries, there are some metrics used by financial experts. The ROI and IRR are two of the many metrics used by firms and companies to evaluate their financial standings.

Return Of Investment (ROI), also known as Rate Of Return (ROR), is dubbed as the easiest, not to mention, the most commonly used metric by many business firms today. This index shows a certain percentage that indicates whether your investments have grown or shrunk within a specific period of time.

Computing the ROI is relatively quick and simple. It only involves two values, namely, the initial investment, and the resulting value of the investment (whether it grew or not). You just need to subtract the initial investment from the resulting investment. Then, you are just going to divide the answer by the same value of the initial investment. The answer is obviously expressed as a percentage. So, if you have value A as the initial investment, and B as the resulting investment, your formula is simply: ROI = (B ‘“ A) / A.

The next metric is the Internal Rate of Return (IRR). It is also known to many as the Annualized Percentage Yield (APY). It is the yearly compound rate (yield) that can be gained from the money invested, and takes into consideration almost all the other financial variables.

Compared to the ROI, the IRR is a more complex metric, because it not only takes into consideration the increase of the investment value, but also the timing of the cash flow. This is perhaps why some business minded individuals are discouraged in regards to the tedious solving for the IRR value. Nevertheless, modern tools like Google docs and MS Excel have enabled the automatic function of calculating IRRs. Thus, the IRR has become the most trusted, and most accurate metric for assessing investment stats, even if you incorporate many other variables, such as dividends and taxes.

In summary,

1. ROI is a simple finance metric for investments, whereas IRR is a more complex metric.
2. ROI is and was a more commonly used metric, especially when computers were not yet that popular, compared to the IRR.
3. ROI only makes use of two values and two operations (division and subtraction), whereas the IRR uses a more complex mathematical formula and algorithms, and is somewhat unsolvable using a purely analytical means.
4. IRR is the more accurate metric compared to the ROI, because it can incorporate multiple variables or values in its equation.
