Calculating age from a birthdate in Excel may seem tricky, but it’s really a piece of cake once you get the hang of it. All you need is the birthdate and the current date to get started. With a simple formula, Excel can do the math for you and give you the age in years. So, if you’re ready to find out how old you or someone else is in Excel, just keep reading!
Step by Step Tutorial: How to Calculate Age from a Birthdate in Excel
Before diving into the steps, you should know that calculating age in Excel involves using the DATEDIF function. This function calculates the difference between two dates, which is exactly what we need to find out someone’s age.
Step 1: Enter the Birthdate
Type the birthdate into a cell in Excel.
When you’re entering the birthdate, make sure it’s in a format that Excel recognizes as a date, such as MM/DD/YYYY or DD/MM/YYYY. This will ensure that when we use the DATEDIF function, Excel will calculate the age correctly.
Step 2: Enter the Current Date
Type the current date into another cell in Excel.
Just like with the birthdate, the current date should be in a format recognized as a date by Excel. You can also use the TODAY() function to automatically input the current date.
Step 3: Use the DATEDIF Function
Type the DATEDIF function formula into a new cell to calculate the age.
The formula follows this structure: =DATEDIF(start_date, end_date, "Y"). You’ll replace start_date with the cell containing the birthdate and end_date with the cell containing the current date.
Step 4: Press Enter
After typing in the formula, press enter to calculate the age.
Once you press enter, Excel will display the age in the cell where you entered the formula. If you followed the steps correctly and used the right date format, the age should be accurate.
After completing these steps, you’ll have the age displayed in years in the cell where you entered the DATEDIF formula. If you need the age in months or days, you can modify the formula accordingly, but that’s a story for another day.
Tips: How to Calculate Age from a Birthdate in Excel
- Make sure the dates are entered in a format that Excel recognizes.
- Use the TODAY() function if you want Excel to automatically use the current date.

Frequently Asked Questions
What if I need the age in months instead of years?
You can modify the DATEDIF formula to calculate months by changing the "Y" to "M".
Can I use this formula to calculate age as of a specific date, not just today?
Yes, simply replace the TODAY() function or current date with the specific date you want to calculate the age as of.
Does the birthdate format matter?

What if Excel doesn’t recognize my date format?
