What is Interest rate?

An interest rate is like a tiny extra price you pay for borrowing something from someone else, or getting a little extra if you lend them something.

Imagine you have a lemonade stand and you borrow $10 from your friend to buy more lemons. At the end of the week, instead of just giving back the $10, you give back $11 because of the interest rate. That extra dollar is like a thank-you note for letting you use their money.

How it works

Let’s say your friend agrees to an interest rate of 10%. That means for every $10 you borrow, you’ll pay back $11, the original $10 plus $1 extra (which is 10% of $10).

If you borrow money from a bank or someone else, they might use that interest rate to figure out how much more you’ll need to pay back. It’s like a little math rule that helps them know how much extra to ask for, and it can be different depending on who lends the money and when.

Sometimes people even get extra money if they lend theirs out, just like you got an extra dollar for using your friend's money!

Examples

  1. A bank lends you $100 and charges $5 for borrowing it, the $5 is the interest rate.
  2. If you save money in a bank, they might give you extra money as a thank-you, that's also an interest rate.
  3. Interest rates go up when there’s more inflation or less money in the economy.
