Compound Annual Growth Rate (CAGR) Definition

What Is the Compound Annual Progress Charge (CAGR)?

The compound annual development price (CAGR) is the rate of return (RoR) that might be required for an funding to develop from its starting stability to its ending stability, assuming the earnings have been reinvested on the finish of every interval of the funding’s life span.

Key Takeaways

  • The compounded annual development price (CAGR) is without doubt one of the most correct methods to calculate and decide returns for something that may rise or fall in worth over time.
  • Traders can evaluate the CAGR of two options to guage how properly one inventory carried out in opposition to different shares in a peer group or a market index.
  • The CAGR doesn’t mirror funding threat.

To calculate the CAGR of an funding:

  1. Divide the worth of an funding on the finish of the interval by its worth in the beginning of that interval.
  2. Elevate the end result to an exponent of 1 divided by the variety of years.
  3. Subtract one from the following end result.
  4. Multiply by 100 to transform the reply right into a share.

What the CAGR Can Inform You

The compound annual development price isn’t a real return price, however relatively a representational determine. It’s basically a quantity that describes the speed at which an funding would have grown if it had grown on the identical price yearly and the earnings have been reinvested on the finish of every 12 months.

In actuality, this type of efficiency is unlikely. Nonetheless, the CAGR can be utilized to easy returns in order that they could be extra simply understood in comparison with various strategies.

Instance of The way to Use CAGR

Think about you invested $10,000 in a portfolio with the returns outlined under:

  • From Jan. 1, 2018, to Jan. 1, 2019, your portfolio grew to $13,000 (or 30% in 12 months one).
  • On Jan. 1, 2020, the portfolio was $14,000 (or 7.69% from January 2019 to January 2020).
  • On Jan. 1, 2021, the portfolio ended with $19,000 (or 35.71% from January 2020 to January 2021).

We are able to see that on an annual foundation, the year-to-year development charges of the funding portfolio have been fairly totally different as proven within the parentheses.

However, the compound annual development price smooths the funding’s efficiency and ignores the truth that 2018 and 2020 have been vastly totally different from 2019. The CAGR over that interval was 23.86% and might be calculated as follows:

C

CAGR=left(frac$19,000$10,000right )^frac13-1times100=23.86%

CAGR=($10,000$19,000)311×100=23.86%

The CAGR of 23.86% over the three-year funding interval will help an investor evaluate options for his or her capital or make forecasts of future values. For instance, think about an investor is evaluating the efficiency of two uncorrelated investments.

In any given 12 months in the course of the interval, one funding could also be rising whereas the opposite falls. This might be the case when evaluating high-yield bonds to stocks, or an actual property funding to rising markets. Utilizing CAGR would easy the annual return over the interval so the 2 options can be simpler to match.

As one other instance, let’s say an investor purchased 55 shares of Amazon.com (AMZN) inventory in December 2017 at $1,180 per share, for a complete funding of $64,900. After three years, in December 2020, the inventory has risen to $3,200 per share, and the investor’s funding is now value $176,000. What’s the CAGR?

Utilizing the CAGR components, we all know that we want the:

  • Ending Steadiness: $176,000
  • Starting Steadiness: $64,900
  • Variety of Years: 3

So to calculate the CAGR for this easy instance, we’d enter that knowledge into the components as follows: [($176,000 / $64,900) ^ (1/3)] – 1 = 39.5%.

Further CAGR Makes use of

The CAGR can be utilized to calculate the typical development of a single funding. As we noticed in our instance above, as a consequence of market volatility, the year-to-year development of an funding will probably seem erratic and uneven.

For instance, an funding might improve in worth by 8% in a single 12 months, lower in worth by -2% the next 12 months, and improve in worth by 5% within the subsequent. CAGR helps easy returns when development charges are anticipated to be unstable and inconsistent.

Evaluating Investments

The CAGR can be utilized to match totally different funding varieties with each other. For instance, suppose that in 2015, an investor positioned $10,000 into an account for 5 years with a set annual interest rate of 1% and one other $10,000 right into a inventory mutual fund. The speed of return within the inventory fund will likely be uneven over the following few years, so a comparability between the 2 investments can be tough.

Assume that on the finish of the five-year interval, the financial savings account’s stability is $10,510.10 and, though the opposite funding has grown inconsistently, the ending stability within the inventory fund was $15,348.52. Utilizing the CAGR to match the 2 investments will help an investor perceive the distinction in returns:

On the floor, the inventory fund might appear to be a greater funding, with practically 9 occasions the return of the financial savings account. However, one of many drawbacks of the CAGR is that by smoothing the returns, The CAGR can’t inform an investor how unstable or dangerous the inventory fund was.

Monitor Efficiency

The CAGR will also be used to trace the efficiency of varied enterprise measures of 1 or a number of corporations alongside each other. For instance, over a five-year interval, Massive-Sale Shops’ market share CAGR was 1.82%, however its buyer satisfaction CAGR over the identical interval was -0.58%. On this approach, evaluating the CAGRs of measures inside an organization reveals strengths and weaknesses.

Detect Weaknesses and Strengths

Evaluating the CAGRs of enterprise actions throughout comparable corporations will assist consider aggressive weaknesses and strengths. For instance, Massive-Sale’s buyer satisfaction CAGR won’t appear so low in contrast with SuperFast Cable’s buyer satisfaction CAGR of -6.31% throughout the identical interval.

How Traders Use the CAGR

Understanding the components used to calculate CAGR is an introduction to many different ways in which traders consider previous returns or estimate future earnings. The components might be manipulated algebraically right into a components to search out the current worth or future worth of cash, or to calculate a hurdle rate of return.

For instance, think about that an investor is aware of that they want $50,000 for a kid’s school schooling in 18 years and so they have $15,000 to speculate right this moment. How a lot does the typical price of return have to be to achieve that goal? The CAGR calculation can be utilized to search out the reply to this query as follows:

textRequired Return =, left ( frac$ 50,000$ 15,000 proper )^frac118-1 occasions 100= 6.90%

Required Return=($15,000$50,000)1811×100=6.90%

This model of the CAGR components is only a rearranged present value and future value equation. For instance, if an investor knew that they wanted $50,000 and so they felt it was cheap to count on an 8% annual return on their funding, they might use this components to learn the way a lot they wanted to speculate to satisfy their aim.

Modifying the CAGR System

An funding isn’t made on the primary day of the 12 months after which bought on the final day of the 12 months. Think about an investor who needs to guage the CAGR of a $10,000 funding that was entered on June 1, 2013, and bought for $16,897.14 on Sept. 9, 2018.

Earlier than the CAGR calculation might be carried out, the investor might want to know the fractional the rest of the holding interval. They held the place for 213 days in 2013, a full 12 months in 2014, 2015, 2016, and 2017, and 251 days in 2018. This funding was held for five.271 years, which is calculated by the next:

  • 2013 = 213 days
  • 2014 = 365
  • 2015 = 365
  • 2016 = 365
  • 2017 = 365
  • 2018 = 251

The entire variety of days that the funding was held was 1,924 days. To calculate the variety of years, divide the entire variety of days by 365 (1,924/365), which equals 5.271 years.

The entire variety of years that the funding was held might be positioned within the denominator of the exponent inside CAGR’s components as follows:

Funding CAGR=($10,000$16,897.14)5.27111×100=10.46%

Clean Charge of Progress Limitation

An important limitation of the CAGR is that as a result of it calculates a smoothed price of development over a interval, it ignores volatility and implies that the expansion throughout that point was regular. Returns on investments are uneven over time, besides bonds which might be held to maturity, deposits, and comparable investments.

Additionally, the CAGR doesn’t account for when an investor provides funds to a portfolio or withdraws funds from the portfolio over the interval being measured.

For instance, if an investor had a portfolio for 5 years and injected funds into the portfolio in the course of the five-year interval, then the CAGR can be inflated. The CAGR would calculate the speed of return primarily based on the start and ending balances over the 5 years, and would basically rely the deposited funds as a part of the annual development price, which might be inaccurate.

Different CAGR Limitations

In addition to the smoothed price of development, the CAGR has different limitations. A second limitation when assessing investments is that irrespective of how regular the expansion of an organization or funding has been up to now, traders can’t assume that the speed will stay the identical sooner or later. The shorter the timeframe used within the evaluation, the much less probably it is going to be for the realized CAGR to satisfy the anticipated CAGR when counting on historic outcomes.

A 3rd limitation of the CAGR is a limitation of illustration. Say that an funding fund was value $100,000 in 2016, $71,000 in 2017, $44,000 in 2018, $81,000 in 2019, and $126,000 in 2020. If the fund managers represented in 2021 that their CAGR was a whopping 42.01% over the previous three years, they’d be technically right. They might, nevertheless, be omitting some crucial details about the fund’s historical past, together with the truth that the fund’s CAGR over the previous 5 years was a modest 4.73%.

CAGR vs. IRR

The CAGR measures the return on an funding over a sure time period. The internal rate of return (IRR) additionally measures funding efficiency however is extra versatile than the CAGR.

An important distinction is that the CAGR is simple sufficient that it may be calculated by hand. In distinction, extra difficult investments and tasks, or those who have many various money inflows and outflows, are finest evaluated utilizing IRR. To again into the IRR, a monetary calculator, Excel, or portfolio accounting system is good.

What Is an Instance of Compound Annual Progress Charge (CAGR)?

The CAGR is a measurement utilized by traders to calculate the speed at which a amount grew over time. The phrase “compound” denotes the truth that the CAGR takes into consideration the results of compounding, or reinvestment, over time. For instance, suppose you’ve gotten an organization with income that grew from $3 million to $30 million over a span of 10 years. In that state of affairs, the CAGR can be roughly 25.89%.

What Is Thought of a Good CAGR?

What counts as a great CAGR will rely upon the context. However typically talking, traders will consider this by eager about their alternative price in addition to the riskiness of the funding. For instance, if an organization grew by 25% in an {industry} with a mean CAGR nearer to 30%, then its outcomes might sound lackluster by comparability. But when the industry-wide development charges have been decrease, similar to 10% or 15%, then its CAGR is likely to be very spectacular.

What Is the Distinction Between the CAGR and a Progress price?

The principle distinction between the CAGR and a development price is that the CAGR assumes the expansion price was repeated, or “compounded,” every year, whereas a standard development price doesn’t. Many traders want the CAGR as a result of it smooths out the unstable nature of year-by-year development charges. For example, even a extremely worthwhile and profitable firm will probably have a number of years of poor efficiency throughout its life. These dangerous years might have a big impact on particular person years’ development charges however would have a comparatively small affect on the corporate’s CAGR.

Can the CAGR be Unfavorable?

Sure. A adverse CAGR would point out losses over time relatively than positive factors.

What Is Danger-Adjusted CAGR?

To check the efficiency and threat traits amongst numerous funding options, traders can use a risk-adjusted CAGR. A easy methodology for calculating a risk-adjusted CAGR is to multiply the CAGR by one minus the funding’s standard deviation. If the usual deviation (i.e., its threat) is zero, then the risk-adjusted CAGR is unaffected. The bigger the usual deviation, the decrease the risk-adjusted CAGR will likely be.
