How to Calculate Age in Excel: Complete Step-by-Step Tutorial

Calculating your exact age is essential for many official and personal reasons. While Excel provides powerful formulas to derive your age from your birthdate, sometimes an easy online tool can give you quick, precise results. At AgeCalcAI.com, we offer a free online age calculator tool compatible with requirements in the USA, India, UK, Canada, and more.

Primary Method: Using the DATEDIF Formula to Calculate Age in Excel

The Excel DATEDIF function is a simple way to calculate age by measuring the difference between your birthdate and today's date.

Use this formula to calculate age in years:

=DATEDIF(Birthdate, TODAY(), "Y")

• Replace Birthdate with the cell containing your date of birth.
• TODAY() returns the current date dynamically.
• "Y" calculates the time in complete years.

Calculating Exact Age in Years, Months, and Days

You can get a detailed age breakdown using this extended formula:

=DATEDIF(Birthdate, TODAY(), "Y") & " Years, " & DATEDIF(Birthdate, TODAY(), "YM") & " Months, " & DATEDIF(Birthdate, TODAY(), "MD") & " Days"

This formula calculates years, months, and days separately, giving you precise age information.
