Tune in to Penny Radio for the second part of our exploration of interest.  In this episode we look at some real world examples of when you'll come across interest.  We'll find out what the Annual Equivalent Rate on savings accounts and the Annual Percentage Rate of Charge on loans are.  We'll also look at whether using our savings to pay off expensive debt is a good idea.  Remember to check out the show notes on the website to see these examples and try putting in your own numbers for your own personal situation.
