However, updates to account balances and funds availability may take up to 2 bank business days. If you pay your Bank of America credit card from a checking or savings account with another financial institution, your payment will be requested as an electronic transfer within 24 hours from the time you submit it online. A debit will appear on your checking account and on your credit card statement online within 2 business days.
