Illustration: what one percentage point is worth
Assumptions: a $10M starting portfolio, annual compounding, and no contributions or withdrawals. If lower costs raise the net return from 10% to 11% a year (for example, by cutting total annual costs from 2.5% to 1.5%), the portfolio grows to about $28.39M instead of $25.94M after ten years. The difference of about $2.46M equals roughly 25% of the initial capital, or about 9.5% more terminal wealth than the 10% scenario. This is an arithmetic illustration, not a forecast of investment returns.
