You can also get cash advances using a credit card at an ATM. Individuals should also be aware that many banks charge transaction fees — generally ranging from 50 cents to $3 per transaction - for using another bank's ATM.

Cash Advance: A borrower may obtain cash on the spot by using their card at a bank or an ATM. The amount of the cash advance is deducted from your available credit line or funds on deposits.

Fixed Rate: A set APR that does not change in response to interest rate changes and conditions. A Variable Rate periodically goes up or down based on fluctuations in market interest rates as reflected in a published index (e.g., the prime rate published in the Wall Street Journal).

Grace Period: A period of time — usually 20-25 days — when you're not charged interest for purchases you've made. For example, if the billing date on your credit card bill is May 1 and you have paid your prior balance in full, you may have until May 20 to pay your new balance in full. If you do, you will not be charged interest. If your payment arrives after May 20 — or if you don't pay the entire balance — you may be charged interest from the date of purchase as posted. Some accounts have no grace period, which means interest is charged on purchases from the date they are posted.
