A late payment is a delinquency of 30 days or more on any account (installment or revolving), reported by the creditor to the credit bureaus.
It’s important to understand that a partial payment may be considered as late. For example, if your scheduled payment is $50 and you make a payment of $45, a late payment can still report on your credit history if it’s over 30 days past due.
The good news is that even if you pay your account 25 days late, a late payment will NOT be reported to the credit bureaus.
If you’re going to be late, make sure that you make your payment before it becomes 30 days past-due and pay the account in full, including any late fees.
Ideally, you should try to pay all of your bills on time.
