An annualized total return is the geometric average amount of money an investment earns each year over a given period. The annualized return formula is calculated as a geometric average to show what an investor would earn over some time if the annual return were compounded.
An annualized total return provides only a snapshot of an investment's performance and does not give investors any indication of its volatility or price fluctuations.
Key Takeaways
An annualized total return is the geometric average amount of money an investment earns each year over a given period.
The annualized return formula shows what an investor would earn over a period of time if the annual return were compounded.
Calculating the annualized rate of return needs only two variables: the returns for a given period and the time the investment was held.
To understand what annualized total return is, it helps to compare the hypothetical performances of two mutual funds. Below is the annualized rate of return over a five-year period for two funds:
Mutual Fund A Returns: 3%, 7%, 5%, 12%, and 1%
Mutual Fund B Returns: 4%, 6%, 5%, 6%, and 6.7%
Both mutual funds have an annualized rate of return of 5.5%, but Mutual Fund A is much more volatile. Its standard deviation is 4.2%, while Mutual Fund B's standard deviation is only 1%. Even when analyzing an investment's annualized return, it is important to review risk statistics.
Annualized Return Formula and Calculation
The formula to calculate the annualized rate of return needs only two variables: the returns for a given period of time and the time the investment was held. The formula is:
For example, take the annual rates of returns of Mutual Fund A above. An analyst substitutes each " r " variable with the appropriate return and "n" with the number of years the investment was held. In this case, five years. The annualized return of Mutual Fund A is calculated as:
An annualized return does not have to be limited to yearly returns. If an investor has a cumulative return for a given period, even if it is a specific number of days, an annualized performance figure can be calculated; however, the annual return formula must be slightly adjusted to:
For example, assume a mutual fund was held by an investor for 575 days and earned a cumulative return of 23.74%. The annualized rate of return would be:
Difference Between Annualized Return and Average Return
Calculations of simple averagesonly workwhen numbers are independent ofeach other. The annualized return is used because the amount of investment lost or gained in a given year is interdependent with the amount from the other years under consideration because of compounding.
For example, if a mutual fund manager loses half of her client's money, she has to make a 100% return to break even. Using the more accurate annualized return also gives a clearer picture when comparing mutual funds or the return of stocks that have traded over different periods.
Reporting Annualized Return
According to the Global Investment Performance Standards (GIPS)—a set of standardized, industry-wide principles that guide the ethics of performance reporting—any investment that does not have a track record of at least 365 days cannot "ratchet up" its performance to be annualized.
Thus, if a fund has been operating for only six months and earned 5%, it is not allowed to say its annualized performance is approximately 10% since that is predicting future performance instead of stating facts from the past. In other words, calculating an annualized rate of return must be based on historical numbers.
How Is Annualized Total Return Calculated?
The annualized total return is a metric that captures the average annual performance of an investment or portfolio of investments. It is calculated as a geometric average, meaning that it captures the effects of compounding over time. The annualized total return is sometimes called the compound annual growth rate (CAGR).
What Is the Difference Between an Annualized Total Return and an Average Return?
The key difference between the annualized total return and the average return is that the annualized total return captures the effects of compounding, whereas the average return does not.
What Is the Difference Between the Annualized Total Return and the Compound Annual Growth Rate (CAGR)?
The annualized total return is conceptually the same as the CAGR in that both formulas seek to capture the geometric return of an investment over time. The main difference is that the CAGR is often presented using only the beginning and ending values, whereas the annualized total return is typically calculated using the returns from several years. This, however, is more a matter of convention. In substance, the two measures are the same.
The Bottom Line
Annualized total return represents the geometric average amount that an investment has earned each year over a specific period. By calculating a geometric average, the annualized total return formula accounts for compounding when depicting the yearly earnings the investment would generate over the holding period. While the metric provides a useful snapshot of an investment's performance, it does not reveal volatility and price fluctuations.
To calculate the annualized portfolio return, divide the final value by the initial value, then raise that number by 1/n, where "n" is the number of years you held the investments.Then, subtract 1 and multiply by 100.
[ Total Return = (1 + annual return)^(number of years) ] Let's return to the example where a $10,000 investment grows to $12,000 over a five year period. The annual return is calculated as [ (12,000/10,000)^(1/5) – 1 = 0.0371 = 3.71% ].
This is displayed as a percentage, and the calculation would be: ROI = (Ending value / Starting value) ^ (1 / Number of years) -1. To figure out the number of years, you'd subtract your starting date from your ending date, then divide by 365.
To annualize your income, use the ratio of the number of months in a year (12) over the number of months in the period you used to get your total. When you divide, your result will always be a number greater than 1. For example, if you totaled your income over 3 months, your ratio would be 12/3 = 4.
You just take your end of year brokerage account balance, subtract your beginning of year balance, factor out all withdrawals and deposits, and then divide the difference by the beginning value amount (and hopefully, this produces a positive percentage figure).
The formula is simple if you have 12 months of data: Add up the monthly income received during a period of 12 months.Divide by 12. There's your annualized income.
An annualized total return is the geometric average amount of money an investment earns each year over a given period. The annualized return formula is calculated as a geometric average to show what an investor would earn over some time if the annual return were compounded.
For instance, suppose an investment returns the following annually over a period of five full years: 10%, 15%, 10%, 0%, and 5%. To calculate the average return for the investment over this five-year period, the five annual returns are added together and then divided by 5. This produces an annual average return of 8%.
A good return on investment is generally considered to be around 7% per year, based on the average historic return of the S&P 500 index, adjusted for inflation. The average return of the U.S. stock market is around 10% per year, adjusted for inflation, dating back to the late 1920s.
Based upon the length of the pay period repre-sented by the pay stubs, (usually weekly, bi-weekly or monthly) the gross income is multiplied by the number of pay periods in a year. That is, 52 x gross wages, 26 x gross wages, or 12 x gross wages respectively.
The annualised rate of return is the average return an investor sees over a set number of years. It is nearly always expressed as a percentage. Calculating this may seem like a simple thing to do but it does require some creative mathematics.
ROI is calculated by subtracting the initial cost of the investment from its final value, then dividing this new number by the cost of the investment, and finally, multiplying it by 100.
Here's how to calculate annual rate of return: Subtract the initial investment you made at the beginning of the year (“beginning of year price” or “BYP”) from the amount of money you gained or lost at the end of the year (“end of year price” or “EYP.”)2. Divide the difference by the initial investment.
We calculate the return over the period since inception and then perform a calculation to figure out the annualised figure. i.e. 100 x ((1 + R)^(1/N) - 1) gives you your annualised return for the period, where N is the number of years since inception and R is the return since inception.
To calculate annualized return in Excel, begin by entering the investment's starting value, ending value, and holding period into the spreadsheet. To calculate the rate of return, divide the ending value by the starting value, subtract one, and then multiply by 100.
For instance, suppose an investment returns the following annually over a period of five full years: 10%, 15%, 10%, 0%, and 5%. To calculate the average return for the investment over this five-year period, the five annual returns are added together and then divided by 5.
What Is Annualized Total Return? An annualized total return is the geometric average amount of money an investment earns each year over a given period. The annualized return formula is calculated as a geometric average to show what an investor would earn over some time if the annual return were compounded.
To calculate the investment's total return, the investor divides the total investment gains (105 shares x $22 per share = $2,310 current value - $2,000 initial value = $310 total gains) by the initial value of the investment ($2,000) and multiplies by 100 to convert the answer to a percentage ($310 / $2,000 x 100 = ...
If the standard return over one period is R 1 and the standard return over a second period is R 2 then the cumulative return over both periods, R c, is (1 + R 1)(1 + R 2) – 1 = R c. The cumulative return is sometimes referred to as the total return.
