This means you pay interest every day until you repay the cash advance, even if you do not have an outstanding balance from the previous statement. On some cards, the interest rate on cash advances is higher than the rate on purchases. Be sure you check the details on the contract sent to you by the card issuer. It is usually much more expensive to take out a cash advance than to charge a purchase to your credit card. Use cash advances only for real emergencies.
Most cards charge a fee when payments arrive late, after the due date.
Some banks wait a few days before assessing this fee, but many impose it the day after the payment was due. Just paying late fees twice in one year can cost you more than an annual fee. To avoid late fees, mail your payment in plenty of time to arrive before the due date. If you pay your bill at the bank's branch or ATM, find out how long it will take to process your payment. Sometimes payments made at a branch or ATM are not credited for a few days.
