Calculating age in Excel

Posted on 2012-04-01

Given a person's Date of Birth (DOB), what is the simplest formula in Excel that will accurately display that person's current age (in years)?  I emphasize "current" because I'm interested in a formula that will auto-update the result each day (i.e. the age will increase automatically on the person's birthday).

Until Barryhoudini comes along and posts how to do it correctly, here's my stab


where A1 is the DOB and B1 is the current date.

Probably more than you want but - assuming your DOB is in A1:

=INT((TODAY()-A1)/365.25) & " years, " & INT(((TODAY()-A1)/365.25-INT((TODAY()-A1)/365.25))*12) & " months, " & TEXT(((TODAY()-A1)/365.25-INT((TODAY()-A1)/365.25)-INT(((TODAY()-A1)/365.25-INT((TODAY()-A1)/365.25))*12)/12)*365.25,"0.0") & " days"

Use this:
B3 is the column with the birthday
