Split your first paycheck before you ever see it

Quick answer: Before your first payday, pick three numbers: what you'll save, what you'll give and what you'll spend. Move the save and give money the hour it arrives. Whatever's left is yours, guilt-free, and when it's gone, it's gone.

You worked 40 hours over two weeks at $13 an hour. You did the math on the drive home. $520.

Then the check shows up and it says something like $470.

Nobody stole it. In the U.S., Social Security and Medicare take 7.65 percent of every paycheck, no exceptions. Depending on your state and the W-4 form you filled out on your first day, there may be state and federal income tax withheld too. In Canada, CPP and EI come off the top. The number you earn and the number you get aren't the same number, and they never will be again for the rest of your working life.

So the first lesson is free. Budget the check, not the hourly rate. Look at your pay stub, find the line that says "net pay," and that's your real number.

If income tax was taken out and you didn't earn much this year, you may be able to get some or all of it back by filing a tax return. That depends on your situation, so ask a parent or a tax preparer to look at it with you. It's worth the twenty minutes.

The mistake almost everybody makes

Most guys get paid, look at the balance, and plan to save "whatever's left at the end."

There's never anything left at the end.

Spending doesn't feel like spending in the moment. It's $7 here, $14 there. A gas station drink and a snack every shift you work is easy to call nothing. At $9 a shift, ten shifts a pay period, that's $90 gone from a $470 check before you've bought a single thing you actually wanted.

The fix is the order. Save first. Give second. Spend third. Your spending money is what remains after the other two are already taken care of, not the other way around.

Pick your three numbers now

You need a starting split. You can adjust it later, but you need one before the money lands, because a decision made on payday Friday with your friends texting you is a worse decision than one made on a Tuesday night at the kitchen table.

A strong starting point for a guy living at home:

• Save 50 percent
• Give 10 percent
• Spend 40 percent

Half sounds like a lot. It is. And you'll probably never have a better chance to do it. Right now somebody else is covering rent, groceries and the electric bill. That won't last forever, and every dollar you stash while it does is a dollar that's working for you later.

On a $470 check, that's $235 saved, $47 given and $188 to spend. Spread over two weeks, $188 is real money for a teenager. You're not living like a monk.

If 50 percent feels impossible, start at 30 and move it up five points every couple of months. A budget you actually keep beats a perfect one you quit by October.

Saving, split into two piles

Saving works better when the money has a job.

Pile one is for something you're working toward. A used truck. A laptop for school. Grad, which costs more than most guys expect. (Run the numbers in what grad really costs and how to pay for it yourself and you'll see why starting early matters.) Give it a name and a target. "Truck: $3,000" is something you'll protect. "Savings" is something you'll raid.

Pile two is money you don't touch. It's not for a goal you can see yet. It's for the version of you at 22 who needs a deposit on an apartment, or a car repair, or a cushion between jobs. Some families open a custodial Roth IRA for a teen who has earned income, which lets that money grow for decades. Whether that fits you is a conversation for your parents and, ideally, someone who does this for a living.

A rough split is 30 percent to the goal and 20 percent to the untouchable pile, but adjust it to what you're actually saving for.

The give bucket is the one guys skip

It's also the one you'll be proudest of.

Ten percent of a $470 check is $47. That's not going to change the world, and that's not the point. The point is that the first paycheck sets the pattern. A guy who gives from his first check gives from his fiftieth. A guy who waits until he "has more" usually never starts.

Where it goes is up to you. A few ideas that actually work:

• Cover a tank of gas for your mom or dad without being asked
• Buy your little brother the cleats he needs for the season
• Drop it at a local food bank or a cause you believe in
• Pick up lunch for a buddy who's been having a rough stretch, and don't make a thing of it

If you borrow the family car to get to work, bring it back with more gas than it had when you took it. Even if it was near empty when you got it. That's giving too, and your parents will notice faster than you'd think.

One real exception. If your family is tight on money and your parents could use help with bills, then helping at home might be most of your give bucket, or more than 10 percent. That's not a failure of the plan. That's a man stepping up for his people, and there's nothing better you could do with a paycheck. Reliability is built in the house you already live in, and so is generosity.

Make it automatic

Willpower is a bad system. Set it up so you don't have to decide every two weeks.

• Open a checking and a savings account with a parent. Under 18, most banks need an adult on the account anyway. That's a feature. Someone who's done this for 25 years can catch mistakes before they cost you.
• Ask your employer about split direct deposit. A lot of employers let you send part of each check to one account and the rest to another. Put the savings amount straight into savings and you'll never even see it in checking.
• If you can't split it, set an automatic transfer for payday morning.
• Keep the give money separate, even if it's just cash in an envelope in your dresser. When it's set aside, you'll actually use it.

When the spend money runs out

It will. Some pay period you'll blow through $188 by Wednesday.

Then you're done until next payday. Don't pull from savings. Don't borrow from a friend. Don't ask your parents to spot you for something you already had the money for and spent. Sit out the food run, play something you already own, and learn what you spent it on.

That week is annoying. It's also the most useful week of the whole year, because it teaches you more than any article can. You'll go into the next check with a plan.

A tip for slowing it down: check your balance before you buy anything over $20. Just look at it. You'll be surprised how often you put the thing back.

The part nobody sees

Being dependable with money is the same muscle as being dependable with anything else. Showing up on time for your shift, keeping your word, doing what you said you'd do. Reliable men are built at fifteen, not at thirty, and so are guys who don't panic about money at thirty.

Nobody's going to clap when you move $235 into an account you can't spend on Friday night. Nobody's going to see you leave a full tank in the family car.

But a year from now you'll have a few thousand dollars, a habit most adults never build and a family that knows exactly who they can count on. That's a pretty good return on a $470 check.
