Yes, being one day late on your credit card payment will affect your credit score.

Details:

1. Credit reference is an important basis for banks and financial institutions to evaluate a person's credit status. A payment that is one day late may be recorded on your credit report, which can have a negative impact on your credit rating.

2. Banks usually report repayment information to credit bureaus in a timely manner, including whether repayments are on time, payment of late fees, etc. If a payment is one day late, it may be considered a late payment and recorded on your credit report.

3. Overdue records in the credit report will provide references for other financial institutions and affect the success rate of future applications for loans, credit cards and other credit products. A lowered credit rating may result in higher interest rates on loans or the inability to obtain a higher line of credit.

4. Even if there is only a one-day delay, it is recommended to pay off the balance as soon as possible and contact the card issuer to explain the situation to reduce potential credit impact.

Summary:

Being one day late with your credit card repayments will have an impact on your credit score, so it is recommended to make sure you repay on time to avoid late repayments. Maintaining a good credit record is very important for personal financial activities and helps to obtain better interest rates and credit terms.
