Money Conversations by Age, 13 to 18

By Jenna Hale · Last checked August 19, 2026

Most advice about talking to teenagers about money is organized by topic, which is why it never gets used. Nobody wakes up wanting to discuss compound interest. They wake up because a phone bill arrived, or a job application needs a work permit, or a car appeared in the driveway.

So this page is organized by what changes. Work down each block over a year or so. This is general information rather than tax, legal or financial advice, rules change, and state law varies on almost everything below, so check the linked primary sources for your own state.

13 to 14: money becomes theirs to lose

The change at this age is control. They have their own balance, usually attached to a phone, and for the first time the money can genuinely disappear without you noticing until later.

• Set the allowance from real costs, not a national average. Nobody has a trustworthy national average, so build the number from what it is meant to cover. How much allowance for a teenager does that arithmetic with them rather than for them.
• Decide the first card question. A debit card changes what they can do when you are not there, which is the point and also the risk. Settle which controls and alerts are switched on before it arrives, not after the first surprise.
• Cover in-app and in-game spending before it happens. This is where first losses usually occur, and the purchase mechanics are designed to be forgettable. Go through the store settings on the console and the phone together, once.
• Teach the scam shapes, not the scam names. The specific scam changes every year, the shape does not: urgency, secrecy, a stranger who has become friendly quickly, and a request that involves gift cards or moving money for somebody else. Scams that target teenagers is the version to read together.
• Freeze their credit. A parent or guardian can place a free freeze on a minor’s file, and the FTC’s page on child identity theft lists what you need: your government ID, proof of address, their birth certificate and their Social Security card. Our walkthrough is freeze your child’s credit. It costs nothing and it is the highest-value hour on this page.
• Say the thing about payment apps once. Money in a cash app is not protected the way money in a bank is, because FDIC coverage reaches it only as pass-through at a partner bank.

The conversation that does the most work at this age is the one where they guess what household things cost, and are wrong by a wide margin.

15 to 16: earning changes everything

The change here is income. Under federal rules, per Department of Labor Fact Sheet #43, 16 is the basic minimum age for employment, and 16 and 17 year olds may work unlimited hours in any job not declared hazardous. Fourteen and 15 year olds may work only in a limited set of non-hazardous jobs, outside school hours, and they are the only group with federal caps on hours and on time of day. Those caps are strict, some states are stricter still, and the full table with the summer extension is on how many hours can a 14 or 15 year old work. Read it before agreeing to a schedule, and check whether your state requires a work permit.

Then, in order, as it actually happens:

• The W-4 conversation, before the first shift. It is short, it is the first tax form of their life, and getting it wrong is annoying rather than serious. How to fill out a W-4 for a teenager.
• The first paycheck shock. Almost every teenager expects hours times rate and gets something smaller. Why is my teen’s first paycheck so small is worth reading before payday, not after.
• Whether they have to file. There are three separate IRS filing triggers for a dependent, they are set per tax year, and the self-employment one is much lower than the others, which is what catches babysitting and mowing money. Does my teenager have to file taxes has the current figures with their tax years attached. Filing can be worth doing even when it is not required, because withheld tax comes back.
• Hand over a category. Clothes is the usual one, and giving them the budget rather than the veto is the point.

17 to 18: things become legally theirs

The change here is legal rather than practical, and it arrives on a birthday whether anyone prepared for it or not.

• The car, which is really an insurance conversation. Gas is the visible cost and the smaller one. Should teens pay for gas and insurance splits the bill into parts that can be shared.
• Credit, before they are marketed to. At eighteen the offers start. What can be built before then, and what cannot, is in building credit before 18. Note also that the FTC says a minor aged 16 or 17 may request and remove a credit freeze themselves, so tell them the freeze exists before they run into it while applying for something.
• Buy now pay later, which they will meet at a checkout. It looks like a payment option and behaves like credit, and the missed-payment fee is the part nobody reads.
• Anything held in a custodial account. Custodial money transfers to them at an age set by state law and account terms, commonly stated as either 18 or 21. We do not publish a state table for this because no reliable national roll-up exists. Ask the brokerage, name your state, and get the answer in writing.
• The leaving-home number. Not a lecture, an actual sheet with actual figures for your town. Rent, utilities, food, phone, transport and insurance, priced where you live, on one page.

What this looks like

Paige is seventeen, has a license, and works two evening shifts a week. Her parents did none of this in order, which is normal.

What they did over one autumn: sat down once with her pay stub and worked out where the missing money had gone, added her to the car insurance and split the increase rather than the gas, and spent twenty minutes on the custodial account her grandmother had opened, where the useful discovery was that nobody in the family knew what age it transferred at. They called the brokerage and found out. Those are three short conversations, none longer than half an hour.

The one they nearly skipped was the freeze, which Paige had to lift herself the following spring. It took ten minutes because she knew it existed. It would have taken a week of confusion if she had not.

Four things worth repeating at every age

1. What things actually cost here, in real numbers, whenever it comes up naturally.
2. That every price is a trade against something else, said out loud when you make the trade.
3. That being scammed is something that happens to careful people, so telling you early is never going to be the expensive option.
4. That you will answer any question about money in this house honestly, even if the answer is that you would rather not share that particular number.

If the conversations themselves are the sticking point rather than the content, how to talk to your teen about money has the openings and the repair scripts, including the one for after it has gone badly.
