AAoA is average age of accounts. This is a major component in FICO scoring. AAoA is the average age of all of your OC accounts, whether good or bad, or opened or closed. Basically all accounts listed on the Accounts page of your FICO report are included in AAoA. CAs and PRs are not included. It's calculated by figuring the age (in months) of each account from today back through when the account was first opened. The sum of these ages are divided by the number of accounts reporting to create an average age. Per FICO, FICO rounds down AAoA to the nearest whole number (e.g. 2 yrs, 4, yrs, whatever). So, as you add accounts, your AAoA could drop and so could your score. Or maybe you have old accounts dropping off, then that could impact AAoA and your score as well. If you want to cheat, sometimes AAoA is listed within pages 2 or 3 of your FICO report.
DTI is just that...total monthly income divided by the total of your monthly obligations (e.g. minimum reported CC payment requirement, housing, reported loan payment requirement). Basically it's anything on your CR(s). Some lenders also include items not listed like child support, alimony, etc.
