Average Annual Return (AAR) refers to a percentage derived when reporting the historical return.
The average annual return (AAR) measures the money made or lost by a mutual fund over a specific period. It is stated net of a fund's Operating Expense Ratio (OER), but excludes sales charges and, if applicable, brokerage commissions. Investors usually review a mutual fund's AAR before making an investment to measure the fund's long-term performance.
The formula for the AAR is:
AAR = [ (1+ R1) x (1+ R2) x (1+R3) x ... x (1+ Rn)] (1/n) - 1,
R1 = Return in Period 1
R2 = Return in Period 2
R3 = Return in Period 3
Rn= Return in Period n
n = Number of the years in period
There are three main components that contribute to the average annual return of a mutual fund: share price appreciation, dividends and capital gains.
Dividends paid from a company's earnings impact the AAR and reduce the net value of the portfolio. The dividends can be cashed in or reinvested in the fund.
Capital gains are the realized part of the AAR and are paid from a mutual fund that arises from income generation. Stocks can also be sold so a manager can realize a profit from the portfolio. Like dividends, capital gains can be cashed out or reinvested in the fund.
