AU adding $7500 in available credit going to help?

[Anonymous]

My partner has added me as an authorized user to her Chase Freedom ($1500 limit) 3 months ago and is showing and to her Capital One Platinum ($6000 limit) last night both will be paid in full on the 17th. Cap One cuts on the 25th so it will report a 0 balance. Chase will cut on the 23rd and will report a 0 balance as well. Will this help my credit much? I have a $500 limit open sky (will also report 0 balance next cut) a cap one with a $200 limit ($32 balance) and a $200 discover (0 balance). If so any clue on how much?

AU can help your score by increasing your AAoA and lowering your % util.  In your case unless your AAoA goes up, I don't think you will see much movement in your FICO score.
