🧭 Your investing roadmap: from the first $100 to a full portfolio

Open this guide in the app →

🎯 In 30 seconds: Investing goes better in a set order. First a cushion and no expensive debt, then free money from an employer match, then a simple low-cost mix in the right accounts, put on autopilot. Only after that do extras like single stocks, a taxable account or alternatives make sense. This page is the map, and every step links to the page that covers it in depth.

Before step 1: the ground floor

Investing money you may need next month is how people end up selling at the worst time. Two things usually come first:

  • A starter cushion. Many people aim for about $1,000 or one month of costs, then build toward three to six months. The Emergency fund planner helps you set the number.
  • No high-interest debt. Paying off a card that charges 24% is a guaranteed 24% return. No investment reliably beats that. The Debt payoff planner lays out a plan.
  • A budget you can repeat. Investing is a monthly habit, so it needs a monthly surplus. See Budget and the one-year money plan in Learn.

The roadmap, step by step

StepWhat you doRead this
1. Park the first $100Open a high-yield savings account. It is insured, earns interest, and gets the habit started.Investing 101: savings and money market
2. Take the matchIf your job has a 401(k) or 403(b) with a match, contribute at least enough to get all of it.Retirement accounts 101
3. Pick the accountAfter the match: an HSA if you qualify, then an IRA, then more in the workplace plan.Which account first, and HSAs
4. Pick the mixDecide how much goes to stocks, bonds and cash for this goal.Asset allocation
5. Pick the fundsOne to three broad, low-cost index funds, or one target-date fund.Simple portfolios and target-date funds (next pages)
6. Check the costsLook at expense ratios and account fees before you buy.What fees really cost you
7. AutomateSet a payroll or monthly transfer so it happens without a decision.Lump sum vs dollar-cost averaging

9. Review once a yearRebalance, raise contributions, check fees and beneficiaries.Asset allocation and rebalancing
Money with a date on it
The roadmap is for long-term money. A house down payment in two years or tuition next fall belongs in savings, CDs or Treasuries, not stocks. Today’s Rates compares those options.

Worked example: Sam, 23

Sam earns $48,000 at his first job. His employer matches dollar for dollar on the first 4% of pay he puts in the 401(k). He has $100 to start and a $1,500 credit card balance.

Month 1Puts the $100 in high-yield savings; signs up for 4% of pay in the 401(k)
Sam’s 401(k) money a year4% × $48,000 = $1,920
Employer match a year$1,920, an instant 100% on those dollars
Months 1–6Pays off the $1,500 card, then builds savings to one month of costs
Month 7 onward$300 a month into a Roth IRA, in one target-date or total-market fund
$300 a month for 10 years at an assumed 6% a yearAbout $49,000
Same $300 a month kept up for 30 yearsAbout $301,000

The 6% is an assumption for illustration, not a forecast. The point is the order: Sam never skips the match, and he does not invest while carrying a 24% card balance.

After the core: optional extras

Once the match, an IRA and a simple index mix are running, some people add more. Each of these has its own page in this section:

  • A taxable brokerage account for goals beyond retirement accounts. See How investments are taxed.
  • A few individual stocks, usually kept small. Start with reading a stock page and the financial statements pages, and the Stock Market Trading course for depth.
  • Bonds and Treasuries beyond a bond fund, international funds, real estate, gold or crypto. See the Building blocks pages that follow.
  • Paid help if you want it. See Choosing help: DIY, robo-adviser or financial adviser.
The order people get wrong
The common mistakes are skipping the match, investing while paying credit card interest, and starting with exciting single stocks or crypto before the boring core exists. The core is what builds most of the wealth; the extras are seasoning.

Your one-page checklist

  1. Starter emergency fund in place.
  2. Credit card and other high-interest debt paid off or on a plan.
  3. Full employer match captured.
  4. HSA (if eligible) and IRA open.
  5. A written mix: stocks, bonds and cash percentages for each goal.
  6. Funds chosen; expense ratios written down.
  7. Automatic contributions set.
  8. Beneficiaries named on every account.
  9. A yearly review date in your calendar.
Check yourself
  1. Sam has $1,500 on a 24% credit card and $300 a month to spare. What usually comes first, investing or the card? Answer: The card. Paying it off is a sure 24% return.
  2. Why does the match come before an IRA? Answer: It is free money added to your pay, often a 50% to 100% instant return on those dollars.
  3. Where does money for a down payment in two years belong? Answer: Savings, CDs or Treasuries, not stocks.
  4. Which site tool shows how a mix would have done in past bad years? Answer: The Backtest tool.
