interest rates

Interest rates influence how much you pay for a car, a house, your credit card, even how many jobs get created and how fast the economy grows. But most people don’t really know how they work, who sets them, or why they change. That’s what we’ll unpack today — clearly, practically, and without the jargon. Let’s get smarter. Let’s start with the simplest definition: an interest rate is the cost of borrowing money. If you take out a loan for $10,000 and agree to a 5% annual interest rate, you’re agreeing to pay $500 a year in interest. That’s your cost for using someone else’s money.
