An Excel formula to annualize data

To annualize data from a single month, the formula will be:

=[Value for 1 month] * 12

This works because there are 12 months in a year.

If you had 2 months of data, the formula would be:

=[Value for 2 months] * 6

This works because there are 6 periods of 2 months in a year.

You can apply this to any number of months by simply dividing 12 by the number of months. In other words, this formula:

=[Value for X months] * (12 / [Number of months])

Many more Excel formulas and functions are covered in our Essential Skills and Expert Skills Books and E-books.

You can download a sample workbook showing this formula in action.
