How to teach your kid how banks, savings accounts and interest work

For a lot of kids, the bank is a mystery: you put money in, and somehow it's still there later, sometimes a little more of it. Between 10 and 12, kids are ready to understand how that works, and how to keep it safe.

This is a skill to teach together. Real bank accounts, statements and account numbers belong to grown-ups, and your child learns by sitting beside you, not by logging in on their own.

Skill 1: What a bank does

Start with the big idea in kid words:

• A bank keeps your money safe so you don't have to keep it in a jar.
• The bank uses saved money to make loans to other people, who pay the bank back with extra, called interest.
• The bank shares some of that with savers, by paying them interest too.

The CFPB's Money as You Grow program suggests telling kids: lots of people put money in a savings account to protect it and receive interest on their saving.

Why it's safe

The CFPB suggests explaining that money in a federally insured bank or credit union is protected. According to the FDIC, deposit insurance covers money in accounts like checking and savings at FDIC-insured banks, automatically, up to the legal limit. It does not cover things like stocks or crypto. Credit unions have similar federal insurance. For kids, the short version is: "If the bank closed, the government makes sure savers get their money back."

Skill 2: How interest works

Interest is easiest to understand with a jar and some coins.

1. Start with $10 in a pretend savings jar.
2. "The bank pays 5% a year." That's 50¢ for every $10.
3. After year one: $10.50. Add 50¢.
4. Year two: interest on $10.50, a little more than 50¢. The interest earns interest.

That last step is compound interest, and it's the most important money idea most adults wish they'd learned earlier. A simple chart over 10 years, drawn together, makes it click.

If you tried a "savings match" when your child was younger, as we describe in teaching kids to save, remind them: interest is the bank's version of that match.

Then flip it around: borrowing works the other way. When you borrow, you pay interest. The CFPB's tip for this age: taking out a loan means you pay back what you borrow, plus more.

Skill 3: Read a bank statement together

Sit down with a statement, on paper or on screen, and look for three things:

• Money in (deposits)
• Money out (withdrawals, purchases)
• The balance: what's left

Ask your child to find one of each and explain it. Point out the interest line if there is one, even if it's small.

Keep it private. Cover account numbers before you start, and make it a family rule that bank details stay at home.

Skill 4: Keep money information safe

The CFPB is direct on this for ages 6 to 12:

• Never share personal information online, like a birthday, address, phone number or school.
• Bank and card numbers are especially risky to type online, because someone could steal them.
• Never answer emails from strangers or click pop-up ads.
• No buying online without a parent's permission.

A good test: "If a message asks for money or a password, show a grown-up first. Every time."

Skill 5: Set a six-month savings goal

If your family decides it's the right time, opening or reviewing a youth savings account with your child makes all of this real. The CFPB suggests going to the bank two or three times a year to deposit savings and watching the balance grow on each visit.

Even without an account, a six-month goal works: pick a target, divide it by six, and check in each month.

Make it a quest

In Family Quests, this is the Bank Basics skill, at the top of the Money branch. Every quest here involves a grown-up: learn how a savings account and interest work, read a bank statement with a parent, and the mastery quest, open or review a savings account with a parent and set a six-month goal. Family Quests never asks for or stores any bank details. Start free.

Next: go back to budgeting, or start the Money branch from the beginning with counting money.
