What is the Interest Rate You Earn?
When you deposit money at the bank, you may earn interest on that money -- especially in savings accounts or certificates of deposit (CDs). In a sense, you’re lending money to the bank so they can use it elsewhere. In return, you get interest income. The interest rate is generally quoted as annual percentage yield (APY). For example, a savings account might pay 3% APY.
When an interest rate is quoted with APY, your money compounds -- you earn interest on your initial deposit plus previous interest payments. For more on this, see a visual example of how compounding works. Money doesn’t always compound. Some loans and deposits use simple interest instead.
What is the Interest Rate You Pay?
When you borrow money, you generally pay interest. Lenders want to be compensated for letting you use their assets. Interest rates on consumer loans are often quoted with an annual percentage rate (APR). That number tells you how much you can expect to pay for every year you use the money, and includes fees above and beyond interest costs.terms, especially for short term loans. Also, lenders can manipulate things to make it look like you’re paying less than you are (by quoting a low interest rate but jacking up the price, for example). Always run the numbers yourself and compare options before you commit.
Why do Interest Rates Change?
Rates can change over time. What makes interest rates move? A few factors that affect them are:
- Economic conditions
- How risky the borrower is (good credit means lower interest rates)
- How risky the loan is (short term loans and loans with collateral generally have lower rates)
- How eager the lender is to make loans (or gather deposits, if a bank)
