Money lessons school skipped

A budget isn't a punishment. It's just a plan for your money, made before you spend it instead of after.

Adults often use the 50/30/20 rule: 50% of income to needs, 30% to wants, 20% to savings. That works when you pay rent and buy groceries. Most students don't, so the classic version doesn't fit. If your parents cover your needs, treating half your allowance as "needs money" just gives you an excuse to spend it. Here's a student version that works whether your money comes from allowance, birthday cash, or a part-time job:

• 50% spend. This is your fun money: food with friends, games, clothes beyond what you need. Guilt-free, because it's planned.
• 30% save for something specific. A phone, a car, concert tickets, a school trip. Short-term goals with a name and a price tag. Saving is easier when you know exactly what you're saving for.
• 20% save and don't touch. This is long-term money. It goes into a savings account and stays there. You're not saving it for something. You're saving it, period. This is the habit that matters most later.

The percentages are a starting point, not a law. Earning $600 a month at a part-time job? You might push long-term savings to 30% or 40%, because you'll never have expenses this low again. Getting $20 a month in allowance? Even $4 into savings builds the habit, and the habit is the actual point.

Two practical tips. First, move savings out the moment money comes in. If you plan to save "whatever's left," nothing will be left. Second, track your spending for two weeks before you set your numbers. Most people guess wrong about where their money goes, usually by a lot.

When you put money in a savings account, the bank pays you for keeping it there. That payment is called interest, and it's usually written as an annual percentage: a 4% rate means $100 becomes about $104 after a year.

Why does the bank pay you? Because it uses deposited money to make loans to other customers and charges them higher interest than it pays you. The difference is how banks earn money. Your deposit isn't sitting in a vault. It's working, and you get a cut.

The powerful part is compound interest: you earn interest on your interest. Say you deposit $1,000 at 4%. After year one you have $1,040. In year two you earn 4% on $1,040, not $1,000, so you gain $41.60 instead of $40. That difference looks tiny. Give it time and it isn't. Left alone at 4%, that $1,000 becomes about $1,480 in 10 years and about $2,190 in 20, and you never added a cent. Add a small deposit every month and the curve bends much faster.

This is why starting young is a genuine advantage, not a cliché. A dollar saved at 15 has decades to compound. The same dollar saved at 40 doesn't. Time is the one ingredient you can't buy back later.

A few things worth knowing:

• Rates vary a lot. Some accounts pay close to 0%, others pay meaningfully more. The number to compare is the annual yield, which includes compounding.
• Your money is protected. In the U.S., deposits at insured banks are covered by the FDIC up to $250,000. In Canada, CDIC coverage works similarly up to $100,000 per category. If the bank fails, your money doesn't.
• Savings accounts are for safety, not growth. Interest often doesn't beat inflation. They're the right place for emergency money and short-term goals, not the only place your money should ever live. That's where our investing guide picks up.

A credit score is a number that tells lenders how reliably you've handled borrowed money. In the U.S., the most common scores run from 300 to 850. In Canada, they run from about 300 to 900. Higher is better, and roughly 700 and up is considered good in both countries.

Why should a teenager care? Because your score follows you into almost every big financial moment of early adulthood. It affects whether you can get a car loan and what interest rate you pay, whether a landlord approves your rental application, what you pay for car insurance in many places, and sometimes even background checks for jobs. A strong score can save you thousands of dollars on a single loan, because lenders charge riskier borrowers higher rates.

Your score is built from a few main ingredients. Payment history matters most: do you pay your bills on time, every time? Next is how much of your available credit you're using. Someone using $90 of a $100 limit looks stretched; someone using $10 looks in control. The length of your credit history, how recently you've applied for new credit, and the mix of credit types fill out the rest.

Here's the catch-22 everyone hits at 18: you need credit to build credit, but no one wants to lend to someone with no history. Some legitimate ways around it:

• Become an authorized user on a parent's credit card. Their good history can help build yours, without you even using the card.
• Get a secured credit card once you're old enough. You put down a deposit, that becomes your limit, and using it responsibly builds history.
• Pay every bill on time, including a phone plan in your name. One missed payment can sit on your record for years.

The single best habit: never charge what you can't pay off in full that month. A credit card treated like a debit card builds your score. A credit card treated like free money builds debt at 20%+ interest.

Congratulations, you got the job. Before your first shift, there's paperwork, and it's worth understanding instead of just signing. Here's what to expect.

1. Tax forms come first. In the U.S., you'll fill out a W-4, which tells your employer how much federal income tax to withhold from each paycheck. Most students with one part-time job can simply complete the basic sections. In Canada, the equivalent is the TD1 form. You'll also verify you're legally allowed to work (in the U.S., that's the I-9 with an ID). Don't panic over these forms. They're routine, and you can update them later if your situation changes.
2. Set up direct deposit. Your employer sends your pay straight into your bank account instead of handing you a paper check. You'll need your account number and your bank's routing number (in Canada, your transit and institution numbers), printed on a void check or found in your banking app. Direct deposit is faster, and there's no check to lose.
3. Read your first pay stub carefully. Your gross pay is what you earned. Your net pay is what actually lands in your account, and it will be smaller. The difference is deductions: income tax withholding based on the form you filled out; in the U.S., Social Security and Medicare (together called FICA, about 7.65% of your pay); in Canada, CPP and EI contributions; and sometimes state or provincial taxes. These aren't your employer skimming money. Most of it is prepaid tax and contributions to public retirement and insurance programs.
4. Know that you might get money back. If you earn under a certain amount for the year, you may owe little or no income tax, and filing a tax return can refund what was withheld. Many students skip filing and leave their own money on the table.
5. Pay yourself first. Decide your savings percentage before the first paycheck arrives, and move it the day you're paid. Your first job is the easiest time in your life to build that reflex.

Investing means buying something you expect to grow in value or pay you income over time. It's how money outpaces inflation, and it's less mysterious than it sounds.

The two building blocks are stocks and bonds. A stock is a small ownership slice of a company. If the company does well, your slice can become worth more; if it struggles, worth less. A bond is a loan you make to a company or government, which pays you interest and returns your money at the end. Stocks generally offer higher growth with bigger swings. Bonds are steadier but grow more slowly.

The core tradeoff in all investing is risk versus return. Anything promising high returns with no risk is either a mistake or a scam. There is no third option, and recognizing that will protect you more than any tip ever will.

The most important beginner concept is diversification: don't put everything into one company. If your savings are all in one stock and that company stumbles, you stumble with it. Spread across hundreds of companies, one failure barely dents you. That's why many beginners start with index funds, which are single investments that hold tiny pieces of hundreds of companies at once, essentially buying the whole market instead of betting on one winner.

Your best advantage is time. Markets rise and fall year to year, but historically the broad market has grown over long periods. A teenager investing small amounts has decades for compounding to work, which is a mathematical edge no adult starting late can recover. The goal isn't picking hot stocks. It's owning a diversified slice of the economy and leaving it alone for years.

Practical notes: in the U.S. and Canada, minors generally invest through a custodial account opened with a parent or guardian. Start only with money you won't need soon, keep an emergency cushion in savings, and treat anyone on social media promising quick riches as a warning label, not a mentor. Nothing here is advice to buy any particular investment. It's the vocabulary you need to make your own decisions later.
