What drives the result
Asset-based fees skim a fixed share yearly, so they grow with wealth while adding no value beyond the service. Flat tickets hit small accounts hardest. The lifetime sum understates the damage because skimmed dollars would themselves have compounded.
Recommendations
- •Flat tickets punish small amounts — batch or cross thresholds.
- •Negotiate blended rates once volume passes six figures.
Educational Content

Investment costs compound against you: a 1% annual fee consumes roughly a quarter of returns over 35 years. Brokerage tickets, management fees, expense ratios and advisory retainers all price here — in dollars, horizons and portfolio share.
Concept Explanation
Asset-based fees skim a fixed share yearly, so they grow with wealth while adding no value beyond the service. Flat tickets hit small accounts hardest. The lifetime sum understates the damage because skimmed dollars would themselves have compounded.
