Annual Return Formula:
From: | To: |
The annual return calculation measures the geometric average amount of money earned by an investment each year over a given time period. It shows the compounded rate of growth of an investment over a 5-year period.
The calculator uses the annual return formula:
Where:
Explanation: This formula calculates the compound annual growth rate (CAGR) which represents the mean annual growth rate of an investment over a specified period longer than one year.
Details: Calculating annual returns helps investors compare the performance of different investments over time, assess investment strategies, and make informed decisions about portfolio management and future investments.
Tips: Enter both the beginning and ending values in dollars. Both values must be positive numbers. The calculator will compute the annualized return percentage over a 5-year period.
Q1: Why use annual return instead of simple average?
A: Annual return (CAGR) accounts for compounding effects, providing a more accurate representation of investment performance over time compared to simple averages.
Q2: What is a good annual return rate?
A: This varies by investment type and market conditions. Historically, stock market returns average 7-10% annually, but this can vary significantly year to year.
Q3: Can this formula be used for periods other than 5 years?
A: Yes, the formula can be adapted by changing the exponent to 1/n where n is the number of years in the investment period.
Q4: Does this calculation account for additional contributions?
A: No, this formula assumes a single initial investment with no additional contributions or withdrawals during the 5-year period.
Q5: How does inflation affect the annual return?
A: The calculated return is nominal (not adjusted for inflation). To find the real return, you would need to subtract the inflation rate from the nominal return.
