Somewhere around 8, kids start to care about fairness, rules and keeping score. That makes this the perfect age for the next set of money building blocks, the ones about making things and selling them. The national personal finance standards include how people earn income by 4th grade, but few schools have time for it, so this one usually happens at home.
The best way to teach it is a small, real project. Here's one that fits in a weekend.
The weekend business
Friday: pick something to make or do. Bracelets, cookies, drawings, bookmarks, or a service like washing cars or walking a neighbor's dog with you nearby. Let your kid choose. It matters more that they want to do it than that it's a good business.
Saturday morning: buy supplies with a budget. Give them a set amount, say $10, and let them plan what to buy. Write down what they spend. This is the first lesson: making something costs money before it brings any in.
Saturday afternoon: set a price. Ask what they think it should cost. You'll probably hear something wild, either far too high or far too low. Instead of correcting it, ask: "How much did the supplies for one cost? Would you pay that much for it?" Let them settle on a number. A price is a choice, and they get to make it.
Sunday: sell it. Family, friends and neighbors are the right first customers. Let your kid do the talking and handle the money, with you standing close.
Sunday night: count it up. Use the tally below.
The one-page tally
| Amount | |
|---|---|
| Money spent on supplies | |
| Number sold | |
| Price for each | |
| Money brought in | |
| What's left (profit) |
When they subtract the supplies from what came in, they've just learned profit. If the number is negative, they've learned something even more useful, which is that it's possible to work hard and lose money. Nearly every adult business owner learned that lesson the same way.
What to ask afterward
Skip the lecture and ask questions instead.
- "What sold best? Why do you think people picked that one?"
- "If you did it again, would you change the price?"
- "What would you do with the money left over?"
- "Was anything harder than you expected?"
If something didn't sell, treat it as information. "Nobody wanted the purple ones" is a real market finding, and they found it themselves.
Your job: approve, then step back
The hardest part for parents is letting the kid run it. In a 2025 Wells Fargo survey, 65% of parents said it's hard to let their kids make their own money mistakes. A weekend business is the safest place for a $5 mistake there is.
A good rule is that you approve the big things, like what they sell, who they sell to and what they say, and they do the rest. They pick, they price, they count, and they keep the money (with a savings share, if that's your family's rule). This is a good moment to start saving, since kids are more likely to save money they earned than money they were handed.
If they want to keep going
Some kids are done after one weekend, and that's fine. Others start planning the next batch on Sunday night. If that's yours, the next building blocks are about keeping customers, getting the word out and saving part of every sale. Here's what comes next for 11 to 13 year olds, and here are five lessons a first business teaches on its own.
When a kid wants to sell beyond the neighborhood, Lemonade Stand gives them a real store of their own, with a parent approving every product, price and word.
Frequently asked questions
How do you teach a 9 year old about money?
Let them make something and sell it. A weekend project with a $10 supply budget, a price they choose and family or neighbors as customers teaches cost, pricing and profit at once. Afterward, ask what sold, what they'd change and what they'll do with what's left.
What money skills should an 8 year old have?
By 8, most kids can count change, save toward a goal, and understand that earning money takes effort. Many are ready to learn that making something costs money first, that a price is a choice, and that profit is what's left after the supplies are paid for.
How do you explain profit to a kid?
Profit is what's left after you pay for the supplies. If the beads cost $4 and the bracelets sold for $10, the profit is $6. Kids understand it fastest when it's their own money and they do the subtraction themselves.
What is a good first business for a 10 year old?
Something they already like to make or do. Bracelets, baked goods, drawings, bookmarks, car washing and pet care all work. Services have no supply cost, so the first dollar is all profit, which makes them a gentle place to start.
