How to Teach Kids to Save Money: The Three-Jar System

Kids learn about money a lot like they learn to ride a bike: by trying, wobbling, and trying again. Talking about money helps. Small, everyday choices give kids a chance to practice.

A 2013 research review by University of Cambridge researchers for the UK’s Money Advice Service suggested that foundations for later money habits develop early in childhood (MoneyHelper). This doesn’t mean those habits are fixed at seven. At ages 7–13, children can keep building these skills through everyday practice with small amounts of money.

The three jars

Give your child three containers: glass jars, envelopes or boxes. What matters is that they are clearly labeled and the money is kept separate.

Now — money for small things this week: a snack, stickers, a little toy. Spending it is allowed. That’s the point.
Dream — money for one bigger goal your child chooses: a ball, a game, a set of paints.
Treasury — money that stays for later. It isn’t spent on wants. It grows slowly, and that is the lesson.

How to split the allowance

Start simple and let your child make choices within a simple rule you agree on together.

A starting split: one possible option is 50% for Now, 30% for Dream, and 20% for Treasury. With ten coins of equal value, that’s five, three, and two. Adjust the split together.
Or just one rule: agree on a minimum — at least 10% in Treasury — and let your child decide how to divide the rest.
Sort right away. As soon as money comes in, it goes into the jars. Loose money is easy to spend without noticing.

Pick a dream they can reach

For a first goal, try something your child could save for in four to eight weeks. Draw or print a picture of it and stick it on the Dream jar. Each week, work out together how much more they need.

Older kids (10–13) can do the math themselves: “The ball costs 16 coins. If I put in 2 a week, how many weeks is that?”

Give the Treasury a boost

The Treasury is the hardest jar to love — nothing happens there quickly. If it fits your budget, offer a small savings match: for every $5 your child adds to Treasury, you add $1, up to $4 a month.

Explain it honestly: “This is a family reward for saving. Money in a jar doesn’t earn interest on its own.”

When the Dream jar gets raided

It will happen. Your child sees something in a store and wants to take money from the Dream jar right now.

Try a 24-hour rule: they can take it, but tomorrow. If they still want it after a night’s sleep, let them. Then look at it together: “Let’s work out how this changes your savings timeline.” No scolding — the lesson works best when the choice was really theirs.

Let mistakes happen

If your child spends everything on day one and has nothing left for the weekend, resist the urge to top them up. A small mistake with small money now is much cheaper than a big one later. Talk about it calmly and ask: “What would you do differently next week?”

Use this approach for optional spending. Food, transportation, and other essentials remain the adult’s responsibility.

By age

7–9: use real coins and pictures. Keep it to three jars and one simple rule. Celebrate every time the Dream jar fills a little more.
10–13: add a weekly plan (“how much for Now this week?”), compare prices before buying, and let them track their jars on paper or in an app.

How Babylon Kids helps

In Babylon Kids: Money Quest, children can track Now, Dream, and Treasury with a parent and practice money choices through short stories and mini-games. The app records amounts; it doesn’t hold or transfer money. Coming soon to the App Store.

You can also start with three jars and a few coins.
