Getting Started: Accounts, Funds and a First Investment

The hardest part of investing is usually not picking the right fund. It is starting at all, and then not being knocked off course. Many people wait for the perfect moment, the perfect product or a larger sum, and lose years of compounding while they wait. This chapter turns the rest of the book into a sequence: what to have in place first, which account to use, what to look for in a brokerage, how to choose a simple portfolio, and how to make the first investment and keep it going.

Three things to have in place first

Investing works best on a stable base. Three things make the difference between a portfolio you can leave alone and one you are forced to raid.

A cash reserve. Money for emergencies belongs in a savings account, not in investments, so that a job loss or a large repair never forces you to sell after a market fall. A common target is three to six months of essential spending. Here is how the gap looks for one household.

This household needs $9,000 for three months and has 1.3 months covered, leaving $5,000 to save. Many people build a starter reserve first and keep adding to it while they begin investing.

No high-interest debt. Paying off a credit card that charges 20% or more is a guaranteed return at that rate, which no investment reliably beats. The pay off debt or invest calculator compares the two for your own rates.

The full employer match. If your employer matches 401(k) contributions, contributing enough to get the whole match is usually the best return available, as Volume 1 of the Retirement shelf explains in detail in the library.

Choose the account

Which account you use affects your taxes more than almost any investment choice. The 2026 limits below are set by the IRS and change most years.

• A workplace plan, such as a 401(k) or 403(b). You can contribute up to $24,500 of your own pay in 2026, from pre-tax pay or, if the plan offers it, as Roth contributions. The investment menu is chosen by the employer.
• An IRA. You can contribute up to $7,500 in 2026 across traditional and Roth IRAs combined, plus $1,100 more at 50 or older. You choose the provider and the investments. Roth IRA contributions phase out above income limits that depend on filing status, and a traditional IRA contribution may not be deductible if you have a workplace plan and your income is above a threshold.
• A health savings account. If you are covered by a qualifying high-deductible health plan, you can contribute up to $4,400 for self-only coverage or $8,750 for family coverage in 2026, employer money included. Contributions are deductible, growth is untaxed, and withdrawals for qualified medical costs are tax-free. Many providers let you invest the balance once it passes a minimum.
• A taxable brokerage account. No limits and no restrictions on withdrawals, but interest, dividends and realised gains are taxed. It is the home for goals before retirement and for saving beyond the other accounts.

A common order is the match first, then an HSA or IRA, then more in the workplace plan, then a taxable account. The order shifts with your fees, income and goals; it is a starting point, not a rule.

Choose a brokerage

For a workplace plan your employer picks the provider. For an IRA or a taxable account you choose, and the large brokerages are similar enough that this decision deserves an afternoon, not a month. Look for:

• SIPC membership. If a member brokerage fails, the Securities Investor Protection Corporation protects up to $500,000 per customer, of which up to $250,000 can be cash. It does not protect against investment losses; it protects your holdings if the firm itself collapses.
• No commissions on stock and exchange-traded fund trades, now standard at major brokerages.
• Low-cost index funds and no account minimum.
• Fractional shares and automatic investing, so a fixed amount goes in on a schedule without you placing each order.
• Clear fees for account transfers, paper statements and any advisory service.

Choose the investments: keep it simple and cheap

Three simple structures cover what most beginning investors need. Each spreads money across thousands of companies and bonds.

• A target-date fund. One fund holding stock and bond index funds, which shifts towards bonds as its target year approaches. You choose the fund dated nearest the year you expect to use the money, and it rebalances for you.
• A total market stock fund plus a bond fund. Two funds, with the split you chose in chapter 5.
• Three funds. A total US stock fund, a total international stock fund and a total bond fund. You set the split and rebalance about once a year.

Whatever you choose, look closely at the expense ratio, the yearly cost taken from the fund. Broad index funds can cost a few hundredths of a percent a year; some actively managed funds and advisory arrangements cost one percent or more. The difference compounds.

At a cost of 0.1% a year the account ends near $648,079; at 1.0% it ends near $544,691. The higher cost takes $103,387, with the same savings and the same market. Research on fund performance has repeatedly found that most actively managed funds trail comparable index funds over long periods, largely because of their higher costs. The investment fee calculator runs this comparison for any fund you hold.

Make the first investment, then automate it

The first purchase takes less time than most people expect.

1. Open the account online. You will need your Social Security number, address, employment details and a bank account for funding.
2. Fund it. Link your bank and transfer whatever you have chosen to start with; a small amount is fine.
3. Buy the fund. Search for it, enter the amount, and confirm. For an exchange-traded fund, a limit order at or near the asking price gives price protection, as chapter 4 explains. Check that cash in the account is actually invested; money left in the account's cash sweep earns little.
4. Automate. Set a monthly transfer and an automatic purchase timed with payday.

Automation matters more than the amount. Here is a modest plan, left to run.

Putting in $72,000 over the years grows to about $194,903 at that assumed return, and raising the amount each time your pay rises does far more than finding a slightly better fund.

Habits that keep a portfolio on track

• Rebalance on a schedule, such as once a year or when your mix drifts more than a few points from target, instead of reacting to news.
• Raise contributions with every raise, before the extra pay becomes part of your spending.
• Check less often. Looking at a long-term portfolio daily makes normal swings feel like emergencies.
• Keep records of what you bought and when, especially in taxable accounts, where the purchase price determines the tax on a sale.
