Transferring a balance from a high interest credit card to a new card with a low introductory interest rate can reduce your interest charges and help you get out of debt faster.

Sounds good, right? A balance transfer can be a great tool for paying down debt. But how are the potential savings of a balance transfer calculated? Here are the factors that typically go into your balance transfer calculation:

  • The amount you want to transfer
  • Your current card’s annual percentage rate (APR)
  • Your new credit card’s introductory APR
  • The number of months the introductory interest rate will apply
  • Your new card’s standard APR
  • The balance transfer fee

Other Factors to Consider:

  • The goal of a balance transfer is to pay off existing debt and not add to it. However, in case of emergencies, it’s important to know what the standard purchase APR is because it may be different from the introductory APR.
  • If you make one late payment on your new card you could lose your 0% APR and it may trigger the penalty APR, which is typically a higher APR than the standard APR and applied to existing and future balances.
  • If you are transferring a balance to an existing card and you usually pay for purchases in full each month to avoid interest, transferring a balance will change that. You will be charged interest on purchases unless you choose to pay your entire balance in full, including any transferred balances, by the first payment due date.

To determine the value of a balance transfer offer, you need to pay close attention to the fine print. The savings you could achieve by making a balance transfer vary depending on your personal financial situation. To ensure you will be getting the best deal, take some time to carefully compare offers.
