First, cover the basics
Before investing, make sure you have a small emergency fund and no high-interest debt. Paying off a credit card charging 24% is a guaranteed return that beats almost any investment. Investing money you might need next month is risky, because markets fall as well as rise.
Use a retirement account if you can
If your employer offers a 401(k) match, that is the best first stop — it is free money. Otherwise, an IRA (Roth or traditional) lets your investments grow with tax advantages. These accounts are wrappers; you still choose what to buy inside them.
Buy a broad index fund
For most beginners, a low-cost index fund that holds the whole market is the simplest, most proven choice. Instead of betting on one company, you own a tiny slice of hundreds or thousands. Fees matter a lot over decades, so look for funds with very low expense ratios.
Automate and ignore
Set up an automatic transfer — even $25 a month — so investing happens without willpower. Then leave it alone. The biggest mistake new investors make is panic-selling when the market dips. Time in the market beats timing the market.

Frequently asked questions
Is $100 really enough to start investing?
Yes. Many brokerages have no minimum and allow fractional shares, so you can buy a piece of a fund with a small amount and add to it regularly.
What is an index fund?
A fund that tracks a market index, giving you instant diversification across many companies at very low cost, instead of picking individual stocks.
Should I pay off debt or invest first?
Generally, capture any employer 401(k) match first, then pay off high-interest debt, then invest more broadly.
