Of all the investment concepts that get underexplained relative to their importance, expense ratios are near the top of the list. They’re small enough to ignore — 0.03% sounds like nothing — and they’re invisible in the sense that they’re deducted from fund assets before the returns you see are calculated. But over long investment horizons, the difference between a 0.03% expense ratio and a 1% expense ratio is not a rounding error. It’s tens of thousands of dollars.

What an Expense Ratio Is
An expense ratio is the annual fee charged by a fund to cover operating expenses, expressed as a percentage of assets under management. If you invest 10 million won in a fund with a 1% expense ratio, 100,000 won is deducted from your fund assets annually to pay for fund management, administration, marketing, and other costs — regardless of whether the fund makes money. [1]
The deduction happens at the fund level before returns are reported. If the fund’s gross return is 8% and the expense ratio is 1%, you receive 7%. This makes expense ratios psychologically invisible — you never write a check, you just receive slightly less than you otherwise would have. [2]
My take: the research points in a clear direction here.
