First Job? Here's Exactly What to Do With Your First Paycheck

You just got your first paycheck. Maybe it's $180. Maybe it's $430. Either way, it feels good — that's real money you earned. And right now, your phone, your friends, and every app on your screen are all competing for it.

Before you spend it, take 10 minutes to read this. The decisions you make with your first few paychecks build habits that will follow you for life. Most teenagers blow through their first job income and have nothing to show for it at 22. A few make simple moves that compound for decades.

Here's exactly what to do.

Step 1: Understand What You Actually Took Home

Your paycheck will be less than you expected. This surprises almost everyone the first time.

If you earned $400 this week, you might take home $340 to $370. The difference goes to:

• Federal income tax — withheld based on your W-4 form. At a teen's income, this is usually minimal.
• Social Security tax — 6.2% of your gross wages, every paycheck.
• Medicare tax — 1.45% of your gross wages.
• State income tax — depends on your state (some states have none).

These deductions are not optional and they're not going away. The good news: at your income level, you may owe very little or no federal income tax, and you might get some of what was withheld back as a refund when you file taxes in April.

Your pay stub will show:

• Gross pay — what you earned before deductions
• Net pay — what hits your bank account

Always budget based on net pay. That's what you actually have.

Step 2: Open Two Bank Accounts If You Haven't Already

Before you think about investing or saving goals, make sure your money infrastructure is in place.

You need two accounts:

A checking account — for everyday spending. Your paycheck gets deposited here. You use a debit card for purchases.

A savings account — for money you are not spending. Move money here immediately when you're paid and don't touch it casually.

Good teen-friendly options with no fees:

• Fidelity Youth Account — checking + investing in one, no fees
• Chase High School Checking — parent-linked, no monthly fee
• Capital One MONEY — teen checking, no fees, earns interest
• Ally Bank — excellent high-yield savings account (for the savings portion), currently paying around 4-5% APY

Keep your spending and saving in separate accounts. If they're in the same account, you'll spend the savings. The separation is the system.

Step 3: Use a Simple Paycheck Split

You don't need a complicated budget. At your income level, a three-bucket split works perfectly:

This is flexible. If you're saving for a car or a specific goal, shift more into the savings bucket. If you have no investment account yet, temporarily put the 20% into savings until you get one set up.

The key rule: move money to savings and investing the same day you're paid. Pay yourself first. Whatever's left is your spending money for the week.

What This Looks Like on a $350 Paycheck

• $175 into checking for spending
• $105 into savings account
• $70 into Roth IRA or investment account

That's it. In one year of working 20 hours/week, you'd have invested roughly $1,680 and saved roughly $2,730 — on a part-time job.

Step 4: Build a $500 Emergency Fund First

Before you start investing, build a small emergency fund. $500 is the right target for most teenagers.

Why $500? Because unexpected expenses at your stage of life are usually in that range: a car repair, a medical copay, replacing a broken phone. Without an emergency fund, you're one surprise expense away from raiding your savings or going into debt.

Once you hit $500 in your savings account, keep it there and don't touch it except for genuine emergencies. Then focus the savings bucket on your goals (car, laptop, college, travel) and the invest bucket on your Roth IRA.

Step 5: Start Investing — Even a Little

If you have earned income from a job, you are eligible to contribute to a custodial Roth IRA. This is one of the best financial moves a teenager can make.

Even $50/month invested in a basic S&P 500 index fund starting at 16 can grow to over $500,000 by retirement, thanks to compound interest. You don't need much. You just need to start.

If your parents open a custodial Roth IRA at Fidelity or Charles Schwab, you can contribute up to the amount you earned that year (max $7,000 in 2025). Even $600-$1,000/year makes a meaningful long-term difference.

Not sure what to buy? Start with one of these and leave it alone:

• FXAIX (Fidelity S&P 500 Index) — great if you're at Fidelity
• VTI (Vanguard Total Stock Market ETF) — works at any brokerage

Step 6: Be Intentional About Spending

You've earned this money and you deserve to enjoy some of it. The goal is not to hoard every dollar — it's to be intentional.

A few questions worth asking before any purchase:

• Is this a want or a need right now?
• Will I still care about this in a week?
• Am I buying this because I actually want it, or because I'm bored or stressed?

You don't need to track every purchase on a spreadsheet. Just pause before anything over $30 and ask those three questions. That habit alone prevents most impulse spending.

Real-World Examples

Example: Maya, 16, works part-time at a clothing store

Situation: Maya earns about $350 every two weeks and used to spend almost all of it on clothes and going out.

What she did: She set up a Fidelity account and automatically transfers $70 per paycheck to her Roth IRA ($140/month) and $105 to a savings account. She spends the remaining $105 however she wants.

Result: After 12 months, Maya had $1,680 invested in her Roth IRA, $1,260 saved for a car, and still had spending money every week. She didn't feel deprived.

Example: Carlos, 17, does weekend warehouse shifts

Situation: Carlos earned $2,200 over a summer and had spent all of his previous summer income with nothing saved.

What he did: He put $500 in an emergency fund savings account, contributed $1,200 to a custodial Roth IRA his dad opened, and kept $500 as spending money for the rest of the summer.

Result: That $1,200 Roth IRA contribution, left alone until age 65, is projected to be worth roughly $63,000 at 8% average annual return.

Common Mistakes First-Time Earners Make

Spending the whole thing immediately. Your brain releases dopamine when you buy things. That feeling is temporary. The money habit you build now is not.

Keeping all money in one account. Out of sight, out of mind works in your favor here. Keep savings in a separate account and it won't get spent casually.

Waiting until you earn more to start saving. The habit is the goal, not the amount. Save $10 from your first paycheck if that's all you can manage. The amount will grow as your income grows.

Ignoring the Roth IRA because retirement feels too far away. It's not too far. It's 50 years away, which is exactly how long you need for compound interest to do its most dramatic work.

Your Action Plan This Week

1. Set up a separate savings account if you don't have one.
2. Decide on your split (50/30/20 is a great starting point).
3. The day your next paycheck arrives, transfer the savings and investment portions immediately.
4. Ask a parent about opening a custodial Roth IRA if you haven't already.
5. Set a goal for your savings bucket — car, emergency fund, college? Having a target makes saving concrete.

Your first paycheck is the first chapter. Make it a good one.
