Understanding investment growth measures : CAGR vs IRR

The most important distinction between CAGR and IRR is that CAGR is straightforward enough that it can be calculated by hand. In contrast, more complicated investments and projects, or those that have many different cash inflows and outflows, are best evaluated using IRR. To back into the IRR rate, a financial calculator, Excel, or portfolio accounting system is ideal. CAGR provides accurate forecasts on the annualized rate of growth for investments or specific metrics. To get accurate results, it’s better to use extended periods when calculating compound annual growth rates.

That is, it is the rate at which the Net Present Value of cash flows is equal to 0. As an organization, calculating your growth rate is a great way of tracking and monitoring performance. One of the most insightful metrics to track and calculate is the compound annual growth rate (CAGR). Therefore, XIRR differs from IRR only in its allowance for non-periodic investment cash flows. Note that XIRR is an annualized rate by the above formula, but it can also be adopted for quarterly, monthly or weekly rates of return by substituting 365 with the appropriate number of days. The issue with simple annualized returns is that most investments do not pay in such a manner, but rather the returns are compounded year after year.

Understanding Returns

The IRR is also a rate of return (RoR) metric, but it is more flexible than CAGR. While CAGR simply uses the beginning and ending value, IRR considers multiple cash flows and periods—reflecting the fact that cash inflows and outflows often constantly occur when it comes to investments. So, CAGR and IRR are exactly the same when the interim cash flows all equal zero. Another way to understand IRR is that it is the compound annual growth rate adjusted for the cash flows, accounting for their amount, direction, and timing. Due to the time value of money, earlier cash flows need to be weighed more heavily than later cash flows which is exactly what an IRR calculation does.

By comparing the CAGR of specific business activities with those of similar organizations, you can determine your company’s weaknesses and strengths.

For all three methods, the higher the rate, the more desirable the investment.

The internal rate of return (IRR) also measures investment performance. While CAGR is easier to calculate, IRR can cope with more complicated situations. The IRR also measures the annual growth rate of an investment but it’s more flexible. In contrast to CAGR, more complicated investments, or those that have multiple cash inflows and outflows, are best evaluated using Internal Rate of Return (IRR). Viewed from a different angle, a XIRR calculation is the most generic type of compound annual growth rate calculation. Different measures of return such as relative return, simple annualized return, CAGR, IRR, and XIRR apply to different investment scenarios.

CAGR vs. IRR: Understanding investment growth measures

This is an important tool for any investor to understand because it is the primary way that investors and financial analysts break down a total return for a holding period into an annual rate. Essentially, it allows an investor to see their average returns over a period of time. There are many ways to analyze the profitability and investment returns of a project or property. In commercial real estate, two of the most common metrics that investors use to measure performance are Compound Annual Growth Rate (“CAGR”) and Internal Rate of Return (“IRR”). We will examine each of these in depth, explain how to calculate them, and discuss when to use them. Investors must know how to measure the returns on an investment in order to determine whether the investment is a success or failure.

Absolute and relative return are useful if the time to return of the investments of interest is exactly the same, and there is just one outflow (the initial investment) and one inflow at the end. The type of return can be either compounding or non-compounding within the investment term. For instance, cash flow patterns are typically uneven in a build-to-sell model. One of the best ways for investors to learn about the past performance of a private equity sponsor is to look at the historical CAGR generated by the management team. While it is not necessarily predictive of future results, it will help the investor to understand whether the firm has been successful in the past. It will also allow investors to compare the past performance against alternative firms and asset classes over the same period.

Analyzing historical returns

This is because the latter investment is performing below industry level while the former is well above the industry standard. Average returns are commonly found using average ROI, CAGR, or IRR.

At the end of every tier (except the last one), if we calculate the IRR, it is equal to the applied APY rate and offers us a great sanity check thus ensuring a controlled distribution at every stage.

When running a business or when expecting any sort of cash inflow, it is important for a business or investor to understand this so that they can successfully manage their cash. In situations with multiple cash flows, the IRR approach is usually considered to be better than CAGR. The CAGR helps frame an investment’s return over a certain period of time. It has its benefits, but there are definite limitations that investors need to be aware of. Unlike net present value, the internal rate of return doesn’t give you the return on the initial investment in terms of real dollars. For example, knowing an IRR of 30% alone doesn’t tell you if it’s 30% of $10,000 or 30% of $1,000,000.

CAGR is the average annual return of an investment over a specified period of time. Since it’s possible for a very small investment to have a very high rate of return, investors and managers sometimes choose a lower percentage return but higher absolute dollar value opportunity. In capital budgeting, senior leaders like to know the estimated return on such investments. The internal rate of return is one method that allows them to compare and rank projects based on their projected yield. The investment with the highest internal rate of return is usually preferred. Once the internal rate of return is determined, it is typically compared to a company’s hurdle rate or cost of capital.

CAGR:

Due to volatility in the market, the annual rate of growth will vary in each financial period. For instance, your growth rate for the first year may be 15% only for it to fall to 8% in the next year. With the exception of bonds that have a fixed return until maturity, the growth rate of all other investments will vary each year.

First, it is important to understand why compound interest formulae are used for volatile instruments where there is no actual compounding. Aside from overall organizational growth, you can use CAGR to track the performance of specific business metrics. Once you know how these metrics perform, you have a basis for comparing them against each other. Understandably, your primary focus will be on potential earnings when making investment decisions.

Many of us have trouble understanding how the growth of volatile instruments like equity, bonds gold  or even real estate can be quantified. We come across many terms like  CAGR, IRR and XIRR in this context. The only way I can calculate risk premium is by using the same compounding formula used for the fixed income product to the volatile security. Many of us have trouble understanding how the growth of volatile instruments like equity, bonds gold or even real estate can be quantified.

See here to understand how XIRR for a mutual fund SIP is calculated. Investments are entered as a negative number (-12,000 in this case) and the final maturity value is positive. Moreover, if the risk for the investment with higher returns is significantly higher, the one with lower returns may become more appealing. As you can see, it’s not just about CAGR values, but also the unique circumstances that surround each one. There are plenty of investment vehicles to choose from as an investor.

However, if you increase the number of years to five, the disruption in the second year will only make a minor dent in the formula’s accuracy. So, if you withdraw or add funds to the investment during the forecasting period, the CAGR calculations will not be accurate. Increasing your investment will inflate the CAGR while withdrawing funds will reduce it. In turn, this allows you to predict overall business performance and make revenue projections more accurately. In all this, XIRR calculations take into account the time preference of investors.

Investors should think of IRR as the interest rate earned on each dollar invested over the holding period. In technical terms, the IRR is the discount rate that results from using the estimated cashflows to calculate a net present value (NPV) equal to zero. For more information on net present value calculations, see our article on this topic. The important thing to know is that a higher IRR indicates a more profitable investment. There is never a continuously smooth market cycle that experiences linear growth.

There are advantages and disadvantages to using CAGR and IRR when evaluating or measuring the performance of commercial real estate investments. However, some months may result in market or business volatility, where the investment return will be less than $5,000, or even be zero. This would impact their ability to make debt payments or fund working capital. A smart financial analyst will alternatively use the modified internal rate of return (MIRR) to arrive at a more accurate measure.

So one will have to take into account the date of investments and receipts along with the amounts involved. However, the maturity value is identical to the above case in which annual returns were fixed at 20%. I expanded it explicitly for us to recognize that when the annual returns fluctuate, we need to plug in each year’s return in the above expression.

• In such cases, CAGR cannot capture these flows and so IRR is the correct profitability metric to compute.
• Unlike net present value, the internal rate of return doesn’t give you the return on the initial investment in terms of real dollars.
• If the decision is solely based on IRR, this will lead to unwisely choosing project A over B.
• So, $5,000 absolute return on an investment of $10,000 is equal to 50% relative return.

Like CAGR, internal rate of return, or IRR, is a metric used by commercial real estate investors to calculate the profitability of an investment. Unlike CAGR, the IRR calculation relies on cash inflows and cash outflows over the holding period to provide the investor with a gauge of profitability. Estimates of cash flows over the holding period are typically found in the proforma financial statements for the investment property. IRR is uniform for investments of varying types and, as such, IRR can be used to rank multiple prospective projects on a relatively even basis.
