So recently I was added to my grandfathers Capital One card which has been open for almost 12 Years with a 4.6K limit and 0 balance. Just wondering how much of a point increase will I see from this?
The answer to that question depends on what your credit reports look like now. The answer can vary between none at all and potentially a lot.
not much in my expierence.
creditors know you are not making the payments, so...
From my experience a big part of it depends on whether your reports are dirty or clean.
Super Clean, No negs at all. Just a ton of inqs (ughhh) and high balances.
Here's two practical examples to help you understand why it could help you a lot or not at all.
EXAMPLE 1: You have a very young and very thin account.
* You have exactly one account, which is only six months old.
* By being added as an AU to that card, your Age of Oldest Account will go from 6 months to almost 12 years.
* And your AAoA (Average Age of Accounts) will go from 6 months to just a bit over 6 years.
Expect a lot of help.
EXAMPLE 2. You have a fairly old and thick account.
* You have 10 accounts, your Age of Oldest account is 13 years and your AAoA is 8.
* By being added as an AU to that card, your Age of Oldest Account will not increase at all.
* Your AAoA will be from 8.0 to 8.3 or so
Expect no help.
If you gave people a bunch of information about your profile, they might be able to make guesses. But why do that? Why not instead wait until it reports and then look at your scores. Then you'll know.
