The Best Time to Start: Age by Age, Without Rushing

There's no perfect moment or date that closes the opportunity. Morgan Housel, in The Psychology of Money, writes that what weighs over time is consistency, not the starting point. What changes with age is how you start.

How to do it

Ages 4 to 6: the child can trade one thing for another, tell need from want and see that someone works to receive money. It's all done with household objects and everyday situations.

Ages 7 to 9: they can plan an amount, compare prices and have a goal that takes several weeks. They start explaining their decisions.

Ages 10 and up: they understand the value of effort, compare options and propose a plan. They can start talking about longer-term saving. Berti and Bombi, in The Child's Construction of Economics, and Beth Kobliner, in Make Your Kid a Money Genius, agree that understanding grows in stages. Use them as a map, not an exam.

If you're unsure about the stage, watch what your child asks. What they ask almost always shows what they're ready to learn. Compare them with themselves last month, not with another child.

What it's for

For your child, each stage is lived as something they can do at that moment, without feeling they arrived late. For you, the question "is it too late?" is replaced by "what can they do today?"

What the research says

What matters most is regularity: a little each week is worth more than a lot once. Carol Dweck, in Mindset, offers a word worth using at home: "yet." "You don't understand budgets yet" invites going on; "you don't understand" closes the conversation.

What you'll see over time

In the first weeks the adult may expect quick results; regularity shows with time. Between one and six months the child responds to ideas from their stage and asks new things. In the long run the conversation about money follows the pace of their questions.

Signs it's working

It's working when the child asks about money on their own initiative, when they use an idea from their stage in a real situation and when you adjust the conversation to what they understand.
