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