If you've assumed there's plenty of time to teach your child about money — that it can wait for a high-school class someday — the research has a surprise for you. The most important window may close earlier than anyone told you.
What the science says
In 2013, Cambridge behavioral researchers David Whitebread and Sue Bingham reviewed how children form a relationship with money. Their conclusion, published for the UK's Money Advice Service, was striking: the cognitive foundations of financial behavior — planning ahead, self-control, the ability to delay a reward — are largely in place by around age seven. By the time a teenager finally sits in a personal-finance class, much of the underlying wiring is already set.
This doesn't mean a seven-year-old is finished, or that an older child can't learn. It means the early years are the richest soil — and we've been planting in the wrong season.
Why schools can't be the whole answer
The good news: thirty-nine states now require some personal finance to graduate high school, according to the Council for Economic Education's 2026 survey. The catch: that's high school — a decade after the window the research points to. If we want these habits to take, the early grades and the kitchen table have to do the first, most important work.
What you can do this week
You don't need a curriculum or a finance degree. Start by simply naming money out loud in the moments you already share: the checkout line ("we're choosing this instead of that"), the gas pump, the decision to save for something bigger. Let your child watch you make a choice and explain it. That narration — early, ordinary, repeated — is the lesson.
