Fees Eat Returns

Investment fees look like the smallest numbers in finance: 1% — who would flinch at that? But a fee is charged on your whole balance, every year, forever, and it compounds against you exactly the way returns compound for you. Over decades, the difference between a tiny fee and a "small" one is not pocket change. It is years of your returns.

The teaching example, using a made-up steady 7% yearly growth: $10,000 invested for twenty years. In a fund charging 0.05%, it grows to about $38,300. In a fund charging 1%, the same money in the same market grows to about $32,100. The $6,200 gap went to fees — quietly, one thin slice a year, with no alert and no statement line screaming about it. Same investment, same market, same twenty years; the only difference was a number that looked too small to matter.

The lesson is not that fees are evil — running a fund costs something. The lesson is that fee percentages deserve the same attention as return percentages, because on a long horizon they are the same kind of number.

In the simulation, the fund A/B choice shows a 20-year preview of each fee before you pick, and the debrief calls out what the choice cost or saved.
