Ages 14–17 • High school
Money Talks for Ages 14 to 17
Every money habit they develop as a teenager compounds for six decades. The goal at this age isn't to lecture — it's to front-load the lessons that are cheap now and expensive later.
What 14–17 year olds can handle
Everything. By 16, a teen can grasp marginal tax rates, Roth vs traditional IRAs, credit utilization, and amortization schedules. The ceiling on what they can learn is almost entirely about whether we bother teaching them.
What they can't handle yet is the emotional pull of social spending — friends, dating, status purchases. Your job here is partly informational, partly giving them a framework for “want now vs. richer later.”
Six conversations to try
The first paycheck decode
“"Bring home your first paystub. We're going to go through every line — gross, federal, FICA, state, net. You should know exactly what each one took."”
Why: Their first real paycheck is a once-in-a-lifetime teaching moment. Don't let it pass without the breakdown.
The real cost of a car
“"The car is $8,000. Add insurance ($2,400/yr), gas ($1,800/yr), maintenance ($600/yr), registration. First-year cost: closer to $13,000. Can you actually afford it?"”
Why: Teens anchor on sticker price. The ongoing costs usually kill the math — better to realize that before buying than after.
The credit score origin
“"Your credit score starts forming as soon as you're on a credit line. Here's how the score works — and here's how a single late payment at 18 can cost you a nicer apartment at 22."”
Why: Most 18-year-olds learn credit scores the hard way. Load the concept in advance.
The Roth IRA pitch
“"You earned $2,000 babysitting this year? You can put that into a Roth IRA. In 45 years at 8% average return, that $2,000 is worth $64,000 — tax-free. Want to?"”
Why: Nothing beats compound interest + decades of time + tax-free growth. If they grasp it at 16, they're ahead of 90% of adults.
The college ROI talk
“"Four years. $40,000–$200,000 depending on where. What's the average starting salary for the major you're thinking about? Let's actually look it up."”
Why: Not all degrees pay the same. This isn't about steering them — it's about making sure they pick with eyes open to the math.
The asking-for-a-raise rehearsal
“"You've worked there 6 months, you show up on time, you've done extra. Let's rehearse asking for a $1/hour raise. I'll be your manager. Go."”
Why: Negotiation is a learnable skill. A teenager who's comfortable asking at 16 will be comfortable asking at 26 — and the dollar impact compounds.
Mistakes to avoid
Bailing them out of small mistakes
The $200 overdraft at 16 costs less and teaches more than the $2,000 overdraft at 26. Let them feel proportionate consequences now.
Keeping college costs secret until senior year
They should know the actual cost of the schools they're considering by 10th grade. Surprise debt is the worst kind.
Treating investing as "something you do later"
The teenage years are the highest-leverage investing years of their entire life. A teen who starts at 16 vs. 26 has double the retirement at 65.
Activities to try this month
The Job Application Shadow
Walk them through writing a resume, filling out a W-4 (explain each line), setting up direct deposit. When they get hired, redo the W-4 with them so they understand what they filed.
The Stock Research Day
Pick a company they use every day (Netflix, Apple, Nike). Read one earnings report together. Look at revenue, profit, year-over-year growth. Buy 1 share together through a custodial account.
The Budget-to-$1000 Challenge
Agree on a savings goal ($1,000 by summer). They track income and spending in a spreadsheet or app. You meet weekly for 15 minutes to review. Hit it, and the celebration is bigger than the money.
FAQs
How much allowance for a teenager?
For 14–17, roughly $15–$25/week. Many families scale down allowance as teens start earning their own money from jobs — replace allowance dollar-for-dollar until they self-fund.
Should I co-sign a credit card for my teenager?
At 18, yes — or add them as an authorized user on yours before then. Both approaches start their credit history. Just make sure you agree on rules in advance and they know you can see the statements.
What's the single most important money lesson at this age?
Start investing. Even $25/month at 16 into a Roth IRA (once they have earned income) outperforms $200/month started at 35. Time is doing the work.
My teen has earned income — what's the right next account?
Order of operations: (1) checking account in their name, (2) high-yield savings, (3) Roth IRA once they have $100+ of earned income, (4) brokerage custodial account for learning.
