How Do I Annualize a Number?

Annualizing a number allows you to extrapolate a short-term calculation into an estimated value for an entire year. This calculation can be used to create a yearly estimate for expenses, revenue, production requirements or other financial or operational figures. You may need to use an annualization process when establishing budgets, ordering supplies or determining yearly production rates. While the basic process of annualizing a number is not difficult, the accuracy of the calculation relies primarily on the quality of the original number you utilize.

Step 1

Establish the exact time frame for the number you want to annualize. The number may relate to an hourly, daily, weekly, monthly or other total. For example, you may have an original number that represents the total number of products your company produces during a month. The time frame for this example would be one month.

Step 2

Calculate the number of time periods your number would be replicated during a year. For an original number that represents a monthly total, your number would be replicated 12 times during a year. A weekly number would be replicated 52 times and a daily number would be replicated 365 times during a non-leap year.

Step 3

Multiply your original number by the yearly time periods. For example, if you produce 1,000 items per month, multiply 1,000 by 12 for an annualized total of 12,000.

Step 4

Increase or decrease your annualized total based on factors you anticipate impacting the yearly total. For example, if you anticipate a lower production amount during holiday periods, you could reduce your annualized total. This adjustment should be based on your own judgment, previous data or input from your colleagues.

Step 5

Report your annualized number. Submit your annualized number in a report whenever possible. Explain the process you used to annualize the original number and note any adjustments to ensure an understanding of the context and calculation of the figure you present.

Warnings

  • Calculating an annual percentage rate uses a compounding formula, not an annualization process.
