## What is the formula to calculate the age?

There is no one-size-fits-all answer to this question, as the formula for calculating age will vary depending on the individual’s date of birth and current date. However, a general outline of the steps that could be followed to calculate age can be found below:

Another way would be to use the YEARFRAC function, which returns the fraction of a year between two dates, and multiply that by 12.

## How do you calculate age from age range?

There are a few different ways to calculate age from an age range. One way is to take the midpoint of the age range. For example, if the age range is 18-24, the midpoint would be 21.

For example, if you are trying to calculate life expectancy, you would give more weight to the lower end of the age range since that is when people typically die.
