Index Funds: Simple, Low-Cost Investing for Real People

When you buy an index fund, a type of mutual fund or ETF that tracks a market benchmark like the S&P 500. Also known as passive investing, it doesn’t try to beat the market—it just matches it, with fees often under 0.1%. That’s it. No stock-picking, no market timing, no Wall Street wizards charging you 1% just to do what a computer can do. And yet, over the last 20 years, most actively managed funds have lost to the S&P 500. Not by a little. By a lot.

Why does this matter? Because index funds are the only investing tool that actually works for most people. You don’t need to be a finance expert. You don’t need to watch the news every hour. You just need to start small, stay consistent, and let time do the heavy lifting. That’s why nearly half of all U.S. retirement assets are in index funds. Companies like Vanguard and Fidelity built empires on this idea—not because they’re genius marketers, but because the math doesn’t lie. Lower fees mean more money stays in your pocket. And over decades, that difference turns $50 a month into hundreds of thousands.

It’s not magic. It’s mechanics. An ETF, a traded version of an index fund that moves like a stock lets you buy fractions of a fund for as little as $1. A S&P 500 index fund, a fund that owns the 500 largest U.S. companies gives you a slice of Apple, Microsoft, Amazon, and the rest—without you having to pick which one will win. And if you want to go global, you can add an international index fund, a fund that tracks markets outside the U.S. to spread your risk. These aren’t complicated products. They’re simple tools built for people who want to grow money without stress.

This isn’t about getting rich quick. It’s about not getting rich slowly by paying too much. The data is clear. The options are simple. And the path forward? It’s already been paved—by millions of people who just started small and stuck with it.
