If you paid off three out of four of your credit card accounts how many points will this raise your credit score?
Maybe a lot, maybe none. Your credit scores are calculated based on ALL the information in your credit file at the time they are requested, not just these four accounts.
Were all accounts paid as agreed? What were the dates the accounts were opened? What available credit did you have prior to closing 3 and how much available credit do you have now? Were the accounts delinquent? Do you have any other existing open accounts? What are the dates those were open?
As you can see, the pieces of information fit together in a very complex way. One piece of data affects several others and can alter the whole equation. Once again, that is what a credit score is, a computation based on the accounts you have open.
