How do you annualize the average daily return?

To calculate annualized portfolio return, start by subtracting your beginning portfolio value from your ending portfolio value. Then, divide the difference by the beginning value to get your overall return. Once you have your overall return, add 1 to that number. Next, divide 1 by the number of years you're measuring and write that number as an exponent next to your previous answer. Finally, raise your answer to the exponent and subtract 1 from that number to get your annualized return. To learn how to calculate annualized return with Excel, read on!

To convert from a daily rate to an annual rate, you could multiply by 365 if you do not want to take into consideration the effects of compounding interest. Interest compounding occurs when interest is paid to your account more than once per year. However, if you are expecting the daily returns to produce returns of their own, with such interest deposited in your savings account, you have to use a formula that takes interest compounding into account.

Step 1

Divide the daily return percentage by 100 to convert it to a decimal. For example, if you earn 0.018 percent per day, you would get a daily return rate of 0.00018.

Step 2

Add 1 to the result from step 1. In our example, adding 1 to a daily rate of 0.00018 equals 1.00018.

Step 3

Raise the result from step 2 to the 365th power, where 365 represents the number of times per year the interest is compounded. Continuing with our hypothetical rate, 1.00018 to the 365th would compute to 1.067899983.

Step 4

Subtract 1 from the result from step 3 to get the annual return as a decimal. Subtracting 1 from our figure (1.067899983) to find the annual return rate expressed as a decimal would give us 0.067899983.

Step 5

Multiply the result from step 4 by 100 to convert the annual return rate expressed as a decimal to a percentage. We, therefore, multiply 0.067899983 times 100 to get an annual return rate of about 6.79 percent.

Tip

You can also use the formula (1+R/100)^365-1 where R is the daily interest rate expressed as a percent.

To annualize a number means to convert a short-term calculation or rate into an annual rate. Typically, an investment that yields a short-term rate of return is annualized to determine an annual rate of return, which may also include compounding or reinvestment of interest and dividends. It helps to annualize a rate of return to better compare the performance of one security versus another.

Annualization is a similar concept to reporting financial figures on an annual basis.

Key Takeaways

  • Annualizing can be used to forecast the financial performance of an asset, security, or a company for the next year.
  • To annualize a number, multiply the shorter-term rate of return by the number of periods that make up one year.
  • One month's return would be multiplied by 12 months while one quarter's return by four quarters.
  • An annualized rate of return or forecast is not guaranteed and can change due to outside factors and market conditions.

Understanding Annualization

When a number is annualized, it's usually for rates of less than one year in duration. If the yield being considered is subject to compounding, annualization will also account for the effects of compounding. Annualizing can be used to determine the financial performance of an asset, security, or company.

When a number is annualized, the short-term performance or result is used to forecast the performance for the next twelve months or one year. Below are a few of the most common examples of when annualizing is utilized.

Company Performance

An annualized return is similar to a run rate, which refers to the financial performance of a company based on current financial information as a predictor of future performance. The run rate functions as an extrapolation of current financial performance and assumes that current conditions will continue.

Loans

The annualized cost of loan products is often expressed as an annual percentage rate (APR). The APR considers every cost associated with the loan, such as interest and origination fees, and converts the total of these costs to an annual rate that is a percentage of the amount borrowed.

Loan rates for short-term borrowings can be annualized as well. Loan products including payday loans and title loans, charge a flat finance fee such as $15 or $20 to borrow a nominal amount for a few weeks to a month. On the surface, the $20 fee for one month doesn't appear to be exorbitant. However, annualizing the number equates to $240 and could be extremely large relative to the loan amount.

To annualize a number, multiply the shorter-term rate of return by the number of periods that make up one year. One month's return would be multiplied by 12 months while one quarter's return by four quarters.

Tax Purposes

Taxpayers annualize by converting a tax period of less than one year into an annual period. The conversion helps wage earners establish an effective tax plan and manage any tax implications.

For example, taxpayers can multiply their monthly income by 12 months to determine their annualized income. Annualizing income can help taxpayers estimate their effective tax rate based on the calculation and can be helpful in budgeting their quarterly taxes.

Example: Investments

Investments are annualized frequently. Let's say a stock returned 1% in one month in capital gains on a simple (not compounding) basis. The annualized rate of return would be equal to 12% because there are 12 months in one year. In other words, you multiply the shorter-term rate of return by the number of periods that make up one year. A monthly return would be multiplied by 12 months.

However, let's say an investment returned 1% in one week. To annualize the return, we'd multiply the 1% by the number of weeks in one year or 52 weeks. The annualized return would be 52%.

Quarterly rates of return are often annualized for comparative purposes. A stock or bond might return 5% in Q1. We could annualize the return by multiplying 5% by the number of periods or quarters in a year. The investment would have an annualized return of 20% because there are four quarters in one year or (5% * 4 = 20%).

Special Considerations and Limitations of Annualizing

The annualized rate of return or forecast is not guaranteed and can change due to outside factors and market conditions. Consider an investment that returns 1% in one month; the security would return 12% on an annualized basis. However, the annualized return of a stock cannot be forecasted with a high degree of certainty using the stock's short-term performance.

There are many factors that could impact a stock's price throughout the year such as market volatility, the company's financial performance, and macroeconomic conditions. As a result, fluctuations in the stock price would make the original annualized forecast incorrect. For example, a stock might return 1% in month one and return -3% the following month.

How do you annualize a daily return?

Converting other returns to annual Simply replace the 365 with the appropriate number of return periods in a year. So, for weekly returns, you would raise the daily return portion of the equation to the 52nd power. For monthly returns, you would use 12. And, for quarterly returns, you would use the fourth power.

How do you annualize a daily mean?

To translate a daily wage or service rate into an annual income, multiply your earnings figure by the number of working days in a year. To calculate the workday total, multiply the 52 weeks in a year by the five working days in a regular work week, deriving 260 days as a raw result.

How do you annualize a YTD number?

Divide the number 12 by the number of months since the beginning of the year, which will give you the annualization factor.
