You're ready to start investing

The order of operations

First, contribute enough to get the full employer match. It's an immediate 100% return on a common dollar-for-dollar match and nothing else comes close.

Second, pay off high-rate debt. Clearing a card at 24% is a guaranteed 24% return, which no investment can promise.

Third, build an emergency fund of a few months of expenses.

Fourth, then invest more.

Doing these out of order is the most common expensive mistake, and it usually looks like investing while carrying card debt.

The reason is opportunity cost from Section 4. Clearing a 24% balance is a guaranteed 24% return. Choosing to invest instead is choosing a lower, riskier one on purpose.

The accounts, and what each one is for

401(k) or 403(b): through your employer, where the match lives. Traditional versions reduce your taxable income now; Roth versions are taxed now and come out tax-free later.

Roth IRA: you open it yourself at a brokerage. You contribute after-tax money and qualified withdrawals in retirement are tax-free. Especially favorable when your income is low, which is exactly where most young workers are. Contribution limits and income limits change annually — check IRS.gov for the current year.

HSA: only available with a qualifying high-deductible health plan, and unusually tax-advantaged if you can use one.

Regular brokerage account: no tax advantages, no restrictions on when you withdraw. This is where money goes once the tax-advantaged accounts are full, or for goals before retirement.

A note on access: money in a 401(k) or IRA is meant for retirement, and pulling it out early generally means income tax plus a penalty. Roth IRA contributions — what you put in, not the growth — can usually come back out without penalty, which makes a Roth unusually flexible for someone early in their career. Verify the current rules before relying on that.

If your employer offers no plan at all, a Roth IRA opened yourself is the whole strategy. You do not need an employer to start.

How to actually open one

This is the step the advice usually skips, and it is the one people get stuck on.

For a workplace plan, you enroll through your employer — HR or the plan provider's website. You choose a contribution percentage and you choose what it gets invested in. Both are changeable later.

For a Roth IRA, you open it yourself at a large brokerage. The application takes about fifteen minutes online and asks for your Social Security number, your address, your employer, and a bank account to link.

Then three steps almost nobody tells you about. Move money in. Choose what to buy. Set it to repeat automatically.

You do not need an advisor for any of this, and you should not pay anyone a percentage to do it for you.

Check what the account costs before you open it — separately from what the investments inside it cost. It differs by provider. Charles Schwab’s own site says its standard brokerage account has no minimum to open, no opening or maintenance fee and no inactivity fee, but charges $50 to transfer your whole account to another firm. Vanguard’s own fee schedule charges $25 a year for each brokerage account unless you sign up for electronic delivery of your statements and documents, which waives it. Fidelity’s pricing page says its robo-adviser, Fidelity Go, charges nothing on balances under $25,000 and 0.35% a year once you reach $25,000.

Those are three examples, not recommendations, and fee schedules change. Read the provider’s own fee page before you open anything. The cost of the funds you buy inside the account is a separate charge, covered in Section 43.

Your money can sit as cash for years without you noticing

This is the most common and most expensive beginner mistake, and it is almost invisible.

Money you transfer into an IRA or a brokerage account sits as cash until you actually buy something. It can sit there for years earning almost nothing while you believe you are invested.

After every contribution, check that it was invested. Look for a balance held in something named as a fund, not a cash or settlement position.

Workplace plans usually differ — most now default your contributions into a target date fund automatically. Log in once and confirm which fund, because the default is not always a good one.

Set contributions to invest automatically if the platform allows it. That removes the step you will otherwise forget.

Roth or traditional, when you are early in your career

The difference is when you pay tax. Traditional reduces your taxable income now and is taxed when you withdraw. Roth gives no break now and qualified withdrawals are tax-free later.

The general principle: pay tax at the lower rate. Early in a career you are usually in the lowest tax bracket you will ever be in, which argues for Roth.

There is also a flexibility point that matters at your age. Money you contribute to a Roth IRA — your contributions, not the growth — can be withdrawn at any time, for any reason, with no tax and no penalty. That makes a Roth IRA far less of a one-way door than people assume, and it is a reason not to avoid opening one out of fear of locking money away.

None of that applies to a 401(k), where early withdrawal is genuinely expensive.

If your employer offers a Roth 401(k), the same reasoning applies to the contributions you make there.

The limits, and what they mean at your income

For 2026, under IRS Notice 2025-67, you can put up to $7,500 into an IRA and up to $24,500 into a 401(k) through payroll. Those are separate limits and you can use both.

Almost nobody starting out gets near either number, and you do not need to. $7,500 a year is $625 a month. If you can do $50, do $50.

The Roth IRA has an income ceiling that starts phasing out at $153,000 for a single filer in 2026, per the same IRS notice. If you are reading this you are almost certainly under it.

One thing worth claiming: the Saver's Credit gives you a tax credit for contributing, if your adjusted gross income is under $40,250 filing single for 2026, per IRS Notice 2025-67. It is worth 50%, 20% or 10% of the first $2,000 you put in, so up to $1,000. One catch matters at low incomes — it is nonrefundable, so it can only reduce tax you already owe. Section 41 has the detail, including the change coming in 2027.

These figures change every year. Verify at irs.gov before relying on them.

What a bad year actually looks like

Saying markets fall is not useful unless you know the scale.

Declines are a normal feature of owning stocks, not a sign something has broken. By Ned Davis Research’s count there have been 27 bear markets — falls of 20% or more — in the S&P 500 since 1928, arriving on average every three and a half years.

The average bear market takes about 35% off and lasts roughly ten months. Over a forty-year working life you should expect to live through several, and a 30 to 40% decline is not a crisis scenario. It is the ordinary cost of the long-run return.

If you are investing for something forty years away, that is survivable and historically has recovered. If you need the money in three years, it is not, and it should not be in stocks in the first place. That is the real difference between saving and investing.

The practical test before you start: if your balance fell by a third next year, what would you do? If the honest answer is sell, invest less, or invest in something steadier. Deciding that now is much easier than deciding it during the fall.

The mistake is almost never the decline. It is selling at the bottom and never coming back.

What to actually put money into

A broad, low-cost index fund is the boring answer and it's the right one for almost everyone starting out. It buys a small slice of a very large number of companies at once, which spreads risk without requiring you to pick anything.

Fees matter more than they look. Every fund charges an expense ratio — an annual fee taken as a percentage of whatever you have invested, deducted automatically whether the fund gains or loses. It is disclosed in the fund’s prospectus and on any brokerage listing. A fund charging 1% a year versus one charging 0.05% sounds trivial and consumes a meaningful share of your returns over decades. Look up the expense ratio before you buy.

A target date fund does the allocating for you and adjusts as you age. Perfectly reasonable choice if you don't want to think about it.

This is not stock picking, day trading, or crypto. Those are different activities with different risk, and none of them are where a first-time investor should begin.

What it actually takes to reach a million

The number is smaller than people think, and it depends almost entirely on when you start.

Assuming a 7% average annual return, compounded monthly, to reach $1,000,000 by age 67 you would need to invest roughly $264 a month starting at 22, $329 starting at 25, $477 starting at 30, $700 starting at 35, and $1,045 starting at 40.

At a more cautious 6% return the figures rise to about $363, $440, $613, $864 and $1,240.

Look at what waiting costs. Starting at 22 takes about $264 a month. Waiting until 32 takes about $555 a month — more than double. And the person who waited puts in around $233,000 of their own money to get there, against about $142,000 for the person who started early. Same result, $91,000 more.

Those are illustrations, not promises. Returns are an assumption, markets have losing years, and the real figure will differ. But the shape of it does not change: time does more of the work than contributions do, and every year of delay makes the monthly number larger.

Section 43 covers what to actually put the money into.

Time in the market

Markets fall. That's normal and expected. The people who get hurt are usually the ones who sell during a drop and lock in the loss.

Automatic contributions on a schedule mean you buy at many different prices instead of trying to guess the right moment. Nobody times this well, including professionals.

Set it up, raise it when you get a raise, and then leave it alone.
