Index Funds for Beginners: The 10-Minute Version
What an index fund is, why fees matter more than you think, and the two-fund portfolio that beats most professionals.
By Money Pulse Editors
An index fund buys every company in a market index, the S&P 500, the whole U.S. market, the whole world, in a single purchase. No stock picking, no star manager, no story. You own a slice of everything and collect the average return.
Why 'average' is a superpower
Over 15-year windows, roughly nine out of ten actively managed U.S. stock funds fail to beat their benchmark after fees, according to S&P's long-running SPIVA scorecard. Being average, cheaply and quietly, puts you ahead of most professionals.
The fee that eats your retirement
An expense ratio of 1% sounds tiny. It isn't. On a $100,000 balance compounding at 7% for 30 years, the gap between a 0.05% fund and a 1% fund is roughly $175,000. That money goes to the manager instead of you.

Low-cost access to stocks, ETFs and bonds in markets worldwide. Best for people who want global index funds without the markup.
- A total U.S. or global stock index fund for growth.
- A total bond index fund for stability, with more of it as you get older.
- That's it. Rebalance once a year. Ignore it the rest of the time.
Index funds won't make you rich by Friday. They'll make you rich by boring you for 25 years, which is a far more reliable plan.
