Credit Cards Aging

[3MV]

I have 4 credit cards total, 3 of them I have had less than a year. Will I see a score increase once my cards turn one year old?

Maybe. YMMV. It depends on your credit profile, mix of credit, whether or not AAoA changes, whether or not you have any newer TLs or inquiries under a year, etc. Generally expect a small bump when the newest hits 1 yr.
