You would think that would be true, but the credit reporting system just doesn't work that way.

When you pay an old debt, the negative credit listing doesn't disappear. Once paid, it may appear on your credit report as a paid delinquency, charge off or collection (whatever the case may be.)Additionally, if the delinquency was more than 24 months old, paying it off can actually harm your scores. ALWAYS consult with a credit specialist BEFORE paying off old collection accounts.

Unfortunately, if your goal is simply to repair your credit, merely paying off your debts won't get you there. You also need to work to restore your credit at the same time. Of course, paying your debts in a timely manner may prevent future problems with your credit report.
