How Quickly Does Paying Down A Credit Card Affect Your Credit Score?

How quickly must you pay a credit card to affect your credit score? 

Often it doesn't take very long to reduce the balance in order to have a positive impact on your score. However, before a credit card can have a positive effect on your scores two things must happen:
1) the credit card issuer must report the depreciation to credit bureaus. 2) credit bureaus must update your credit record with the depreciation. 

The absence of a credit score 

Not all credit records are eligible for a credit score. There are minimum score requirements to ensure that results are delivered as specifically as possible. There are several reasons why credit scores may not appear on a credit report, including:

    * The consumer has no activity on the accounts over the last six months
    * The consumer has insufficient credit history to calculate the credit score again or not enough credit established. Generally, two years of credit history is required to obtain a score
    * The file parameters are too large, the file contains 100 lines or more of trade lines and combined search data
    * Incomplete data has been entered to access a report (eg, code generation and middle initial term required by the credit bureau to provide an archive and punctuation)
    * The consumer has been reported to the credit agencies as deceased
    * Consumers have reported being defrauded
    * The consumer has a new credit file without combining with one of the three reporting agencies
    * Incomplete history of residence was registered to access a credit report (2 years minimum)
