ELI5: What is an annuity?

Context: Economics 1 views Apr 1, 2026 2 min read

An annuity is like getting a regular allowance from a big pile of money you saved up.

Imagine you have a big piggy bank full of coins, like all the money you saved for retirement. An annuity is a special deal where you give that piggy bank to a company, and they promise to give you a certain amount of money back every month (or year) for a set time, or even for the rest of your life!

Think of it like this:

  • You give the company your principal, which is all the money in your piggy bank.
  • The company invests your principal and uses the earnings (and some of the principal itself) to pay you regular payments.
  • These regular payments are the annuity payments.
Why would you do this? Well, it can be useful for a few reasons:
  • Guaranteed Income: You know exactly how much money you'll get, and when. This is helpful for planning your expenses.
  • Retirement Security: It helps make sure you won't run out of money when you're older and not working.
  • Professional Management: The company handles investing your money, so you don't have to worry about it.
There are different types of annuities. Some start paying you right away, while others wait until later. Some pay a fixed amount, while others can change depending on how the investments do. It's like choosing different flavors of ice cream! You need to pick the one that fits your needs best. In economics, annuities are an important tool for managing risk and ensuring financial security, especially during retirement.
