## What is annualization?

Annualizing a number means converting a short-term calculation or rate to an annual rate. Typically, an investment that produces a short-term rate of return is annualized to determine an annual rate of return, which may also include the compounding or reinvestment of interest and dividends. This allows a rate of return to be annualized to better compare the performance of one security against another.

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

Key points to remember

• Annualization can be used to forecast the financial performance of an asset, security or business for the following year.
• To annualize a number, multiply the short-term rate of return by the number of periods that make up a year.
• The return of a month would be multiplied by 12 months while the return of a quarter by four quarters.
• An annualized rate of return or forecast is not guaranteed and may change due to external factors and market conditions.

## Understanding annualization

When a number is annualized, it is usually a rate with a term of less than one year. If the yield in question is subject to compounding, the annualization will also take into account the effects of compounding. Annualization can be used to determine the financial performance of an asset, security or business.

When a number is annualized, the short-term performance or profit is used to forecast performance for the next twelve months or one year. Below are some of the most common examples of using annualization.

### Company performance

An annualized return is similar to a execution rate, which refers to a company’s financial performance based on current financial information as a predictor of future performance. The execution rate works as an extrapolation of current financial performance and assumes that current conditions will hold.

### Loans

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

Short-term loan rates can also be annualized. Loan products, including payday loans and title loans, charge a fixed financing fee such as \$ 15 or \$ 20 to borrow a nominal amount from a few weeks to a month. At first glance, the \$ 20 fee for a month doesn’t seem outrageous. However, annualizing the number equates to \$ 240 and could be extremely high relative to the loan amount.

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

### Tax purposes

Taxpayers annualize by converting a tax period of less than one year to an annual period. Conversion helps employees establish a tax plan and manage all tax implications.

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

## Example: investments

Investments are annualized frequently. Let’s say a stock returned 1% in a month in capital gains on a simple (non-compound) basis. The annualized rate of return would equal 12% because there are 12 months in a year. In other words, you multiply the short-term rate of return by the number of periods that make up a year. A monthly return would be multiplied by 12 months.

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

Quarterly rates of return are often annualized for comparison purposes. A stock or bond could generate a return of 5% in the first quarter. 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 a year or (5% * 4 = 20%).

## Special considerations and limitations of annualization

The annualized rate of return or forecasts are not guaranteed and may change due to external factors and market conditions. Consider an investment that returns 1% in a month; the stock would return 12% on an annualized basis. However, the annualized return of a stock cannot be predicted with a high degree of certainty using the short-term performance of the stock.

Many factors can impact a stock’s price throughout the year, such as market volatility, company financial performance, and macroeconomic conditions. As a result, fluctuations in the share price would render the original annualized forecast incorrect. For example, a stock can return 1% in the first month and -3% the following month.
