Guide to Your First Paycheck

Your first real paycheck just hit. Salaried or hourly, doesn’t matter — you earned one number, and a smaller number landed in your bank. Roughly three-quarters to four-fifths of what you earned, depending on your state.

Most of the missing chunk is out of your hands — taxes, FICA, the things your job took out for you. The part you keep is yours to plan. Let’s walk through where the money went, then talk about what to do with what’s left.

First: where the money went

A typical paycheck splits five ways: federal income tax, FICA (your share of Social Security and Medicare), state income tax, pre-tax stuff you opted into (a 401(k), health insurance, HSA), and after-tax stuff. For a 20-year-old making $40,000 in a mid-tax state, with 4% going to a 401(k), it looks like this:

About 19¢ of every dollar goes to taxes, 4¢ goes to your future self (still your money, just locked away for now), and 77¢ lands in your account. The proportions shift a bit with your salary and state, but the picture is mostly the same. Want the breakdown for your own numbers? Use the paycheck tool.

Your plan for the part you keep

Most people don’t have one. The money lands in checking, bills get paid because they have to be, and whatever’s left becomes food, fun, and “I’ll figure out savings next month” — except next month looks the same. Six months in, nothing’s been saved.

The fix isn’t a guilt trip or an app that yells at you. It’s a budget, in the plain sense: a plan that names where each dollar is going before you spend any of it. Once that’s done, the dollars you mean to save show up reliably instead of vanishing.

Budgeting, because you have goals

Budgeting only feels useful once you tie it to something specific you want. So before we talk percentages, think for a minute about what you’d want money for in the next few years. A few common ones for someone starting out:

• A used car — or replacing the one you’ve got.
• Moving out — first month, last month, a deposit.
• A trip after a stretch of work.
• Eventually: retirement.

Those break into two groups. Short-term goals are things in the next few years: the car, the move. Long-term goals are decades out: retirement. The right place to keep money depends on which group it’s for. We’ll get to that in the next section.

The starting framework for the budget itself: split your take-home into three buckets.

A useful technique inside the savings bucket is a sinking fund — money you put aside monthly for a specific upcoming purchase. Saving $200 a month for two years gives you $4,800 toward a used car. You’re not scrambling to come up with the cash when the moment arrives. It’s already there. People build sinking funds for cars, moving costs, holiday gifts, annual insurance premiums, or anything you know is coming but don’t want to surprise you.

Where you put your savings matters

Once a dollar is in your savings bucket, the next question is: where does it sit? Three common places, and they grow your money very differently over time.

• Cash under a mattress (or in a coffee can) earns nothing. It just sits.
• A bank. Checking earns close to nothing too. A high-yield savings account at an online bank like Ally, Marcus, or Wealthfront earns around 4% APY (annual percentage yield, the effective yearly rate after compounding) in 2026 — same money, one transfer away.
• The stock market. A broad index fund (a basket of all the big companies) returns roughly 7% per year on average over the long run, after inflation. Volatile in any given year, but very steady over decades.

What that difference looks like for $200 a month from age 20 to 65 — the 45 years you have between your first paycheck and a normal retirement:

So here’s the rule of thumb that falls out of that chart:

• Short-term goals (a car next year, a move in 18 months): keep the money in a high-yield savings account. Predictable, no risk of it being down 30% the week you need to write the check.
• Long-term goals (retirement, decades out): the stock market. The bumps even out over long stretches, and the gap between 4% and 7% becomes enormous over four decades.

And then there’s when

Where matters — but when matters more. The earlier dollar doesn’t just earn more; it earns for longer.

So here’s what to set up

Three accounts. None are urgent today. All want to be in place before your second paycheck arrives.

1. A high-yield savings account at an online bank (Ally, Marcus, Wealthfront). To set up the transfer, link your checking account (the HYSA confirms it with two small “micro-deposit” amounts you verify, usually 1–3 business days), then schedule a recurring transfer for whatever amount you can sustain — even $25 a pay period matters. This is where your emergency fund lives (start with $1,000, then build toward three months of essential expenses) and where every short-term sinking fund lives.

2. If your employer offers a 401(k) match, contribute at least enough to get the full match — usually 6%. The match is part of your pay, and a 50–100% instant return beats anything else on this list, so it comes before the Roth. (Where to find the deferral setting and how vesting works.) If your job doesn’t offer one, skip to the Roth.

3. A Roth IRA at Fidelity, Vanguard, or Schwab. No employer needed, no minimum to open. Set up an automatic monthly transfer on payday — $100 is enough to start. The transfer is the deposit, not the investment: the money sits as cash inside the Roth until you place a buy order. Buy a single broad-market index fund (or a target-date fund matched to your retirement year). This is your long-term retirement money, invested in the market, growing tax-free for life: you’ve already paid income tax on the dollars going in, so the IRS never touches the growth or your qualified withdrawals. Once it’s set up, forget about it.

For the full roadmap of what comes after — debt, insurance, education savings, generosity — the money order of operations covers the rest.

Set up the three accounts above. Then let time do the work.

Nobody starting later gets the head start you have right now. Compound math doesn’t care how much you save — it cares how long.
