Key Takeaways

  • A 1% difference in annual fees can cost hundreds of thousands of dollars over a 30-year investment horizon.
  • Low-cost index funds with expense ratios under 0.10% deliver the same market returns as most actively managed funds at a fraction of the cost.
  • Fees compound against you just as returns compound for you, making even small percentage differences significant over time.
  • Checking the expense ratio of every fund in your portfolio is one of the simplest and highest-impact steps toward reaching FI sooner.
