Re: Uh Oh

Write down the age (in months) of each account you have (including closed ones)

 

Add them up (total) and divide by the number of accounts you had (not including the new card)

 

Now divide the total (the one you got by adding together the age of each account) (in months) by the number of accounts you have (including the new card)

 

The first was your previous AAoA and the second is your new AAoA
