Most wealth management relationships are priced as a percentage of assets under management (AUM) — typically around 1% per year. That fee structure makes sense when the professional is actively managing investment decisions, because their compensation scales with the outcomes they're responsible for. It makes considerably less sense for coordination work, where the professional isn't managing investments at all.
Here's the structural problem: an AUM-based fee quietly rewards the professional for having more assets under their umbrella — full stop, regardless of whether that's actually the right move for you. Paying down a mortgage early, reinvesting capital into your own operating business, or gifting assets to the next generation are all financially sound decisions that shrink the AUM base a percentage fee is calculated against. An advisor paid a percentage of assets has a quiet incentive to discourage exactly those moves, even when they're clearly in your interest.
A flat-dollar retainer removes that incentive entirely. Whether your coordinator is helping organize a $2 million estate or a $20 million one, whether you pay down debt or add to a portfolio, the fee doesn't change — because the fee was never tied to asset accumulation in the first place. It's priced on the coordination work performed, not on what you own.
Why is a flat retainer better than a percentage-of-assets fee?
- The industry norm
- Roughly 1% of assets under management per year.
- The structural problem
- A percentage fee quietly rewards accumulating assets, even when paying down debt or gifting is the better move.
- The flat-fee fix
- The fee is priced on coordination work performed, so it does not change with what you own.
- Where AUM fees do make sense
- When the professional is actively managing the investment decisions they are paid on.
How do you evaluate an advisor’s fee structure?
- Ask any advisor how they are compensated, in writing.
- Identify whether their fee changes based on advice they give you.
- Compare the total ten-year cost, not the headline percentage.
