If you’ve ever opened up a savings account or taken out a loan, you’ve heard the term interest before. You also probably have a rough idea of what it means—if you have a loan, you have to pay more money back than what you borrowed. If you have a savings account, you get a bit of money back each month.
What exactly is interest, though? Why do you have to pay more interest in certain situations and less in others? Also, how are interest rates determined? In other words...
How does interest work?
The concept of interest is actually pretty simple. It’s a fee that a borrower pays a lender as compensation for the risk of loaning their money out.
For example, let’s say you take out an auto loan to buy a car. After talking with a loan advisor at a financial institution, you get a loan of $6,000 at 5% interest, also known as the interest rate. What this means is that the financial institution is giving you $6,000 for the purposes of buying an automobile, and you in return are paying them five percent of that amount, or $300, in addition to repaying the $6,000.
The same principle works when you open a savings account, CD or IRA. When you put your money in any of these investment vehicles, you are basically setting it aside for the financial institution to use. In return, the financial institution pays you for the privilege of being able to use your money.

When calculating interest, you’ll also want to familiarize yourself with the terms APR and APY. APR stands for annual percentage rate, which is the annual rate of interest you will make on an investment.
APY stands for annual percentage yield, which not only takes into account the annual rate of interest, but also takes into account the frequency with which that interest is applied to your account. This is also known as compound interest.
How Interest Rates Are Set
It’s one thing to know what interest is. It’s another thing entirely to know how financial institutions set interest rates. The short answer is that a lot of factors intertwine to determine how interest rates are set. Among these factors are:
- The Federal Reserve’s federal fund interest rate. This is the rate that financial institutions use to lend to one another and trade with the Federal Reserve itself.
- The prime rate. This is the interest rate financial institutions give to their ideal customers, usually corporate accounts. This interest rate is generally set three percent higher than the federal fund interest rate.
- Market information. Once financial institutions know the federal fund interest rate and have established their prime rate, their analysts will start examining outside information to determine the interest rates for different loans. Among the information an analyst might consider is inflation, the level and growth of the Gross Domestic Product and the ups and downs in market rates, known as interest rate volatility.
- Personal information. When you try to get a loan from a financial institution, that institution will first look at how much you want to borrow and the period of time in which you plan to pay the loan back. They’ll also check your credit score and evaluate what other accounts you’ve held with the institution and for how long. In the case of some loans, such as a mortgage, they’ll take into account what kind of down payment you’re making, as well. All of this information will be used to assess what kind of risk you pose to the financial institution and assign an interest rate to you that will sufficiently cover the financial institution’s risk in lending you the money.
