Having a “fixed” rate means that the APR doesn’t change based on fluctuations of some external rate (such as the “Prime Rate”). In other words, a fixed rate is a rate that is not a variable rate. A fixed APR can change over time, in several circumstances:

  • You are late making a payment or commit some other default, triggering an increase to a penalty rate
  • The bank changes the terms of your account and you do not reject the change.
  • The rate expires (if the rate was fixed for only a certain period of time).
