Bank

Age 6+

A place (real or online) that holds money safely and pays interest on savings.

At a glance

A bank is a business that holds your money safely and pays you a small amount (interest) for letting them use it while it sits there. Banks loan that pooled money out to other people and businesses, and that loan interest is how the bank itself makes money. Kids who get the basic mechanic — "the bank is holding my money, and they pay me a little for the privilege" — have the foundation for every later concept around saving, lending, and credit.

Example sentence

"We deposit your allowance at the bank so it earns interest."

Why this matters for kids

Most kids hear "the bank" mentioned constantly without ever understanding what one is or how it stays in business. That gap fuels later confusion: why does my savings earn interest? Why does the bank give loans? Why is "free checking" a marketing tagline if banks make money? Demystifying the bank as a business — they hold your money for safekeeping, they pay you a small interest rate, they then lend that pooled money to other customers at a higher rate, and the difference is their profit — gives kids a mental model for everything from credit cards to mortgages. It also sets up the most useful adult instinct: banks are services you pay for, sometimes with fees and sometimes with the gap between the interest they pay you and the interest they charge others. Knowing that early makes you a smarter customer for life.

How to teach it

Visit a branch together. The architecture itself does some teaching — vaults, tellers, the seriousness of the lobby. Open a small savings account in their name if your bank allows custodial accounts; many do. Let them hand over the first deposit at the counter — the physical transaction is far more memorable than tapping an app. After a month, show them their statement: "see this $0.18 line? The bank paid you that for letting them hold the money." It seems trivial, but watching free money appear cements the concept of interest forever. For older kids, contrast banks with credit unions — same service, different ownership model — and with online-only banks like Ally or Capital One 360, which often pay better interest because they have no branches to maintain. That comparison teaches them to shop banks by interest rate, the way they would shop sneakers by price.

Common misconceptions

  • The bank gives me money for nothing. The bank pays interest because they are using your deposit to make loans elsewhere; the small amount they pay you is their cost of doing business.
  • Banks are all the same. Interest rates, fees, and overdraft policies vary widely. A teen with a high-yield savings account can earn 10x what a default-checking-account peer earns on the same balance.
  • A bank is a building. Plenty of banks today are entirely online — no branches at all. Often the online-only banks pay the best interest rates because they have lower overhead.
