A balance transfer involves transferring debt from an existing credit card to a new or another existing credit card to save on interest charges. A cash advance, on the other hand, is when you use your credit card to get cash either through an ATM or by transferring it to your bank account. The balance transfer vs. cash advance comparison tilts in favor of the former when it comes to interest rates. This is also usually the case when it comes to fees.
Some credit card companies provide balance transfer checks, which you would use to pay off one credit card’s debt and transfer it to a new one. A few provide convenience checks, which you may use for purposes other than balance transfers. Convenience checks are typically regarded as cash advances.
If you’re thinking about going the balance transfer or cash advance route to pay off credit card debt, opting for the former is usually the better option.
