Advisor fees are rarely a single number — they can combine an AUM percentage, flat charges, and fund-level costs. Understanding each layer is part of any complete advisor evaluation.

Percentage of Assets Under Management (AUM)

The most common structure charges a percentage of the assets the advisor manages for you, typically ranging from about 0.5% to 1.5% annually, often on a sliding scale that decreases as your balance grows. This fee is usually deducted directly from the account.

Flat and Hourly Fees

Some advisors, particularly fee-only planners, charge a flat annual retainer or an hourly rate instead of an AUM percentage. This can be more cost-effective for larger portfolios or for clients who want planning advice without ongoing asset management.

A 1% annual fee on a growing portfolio can reduce total accumulated wealth by a substantial percentage over a 30-year period, purely through lost compounding — always ask for the dollar-equivalent cost, not just the percentage.

Underlying Fund Expense Ratios

On top of the advisor's own fee, the mutual funds or ETFs used in your portfolio carry their own expense ratios. A portfolio built from low-cost index funds might add 0.03%–0.20%, while actively managed funds can add 0.50%–1.5% or more — a layer that's easy to overlook when only comparing the advisor's headline fee.

Common Mistakes to Avoid

  • Comparing only the advisor's AUM fee while ignoring underlying fund expense ratios.
  • Not asking for the total all-in cost as a dollar figure, not just a percentage.
  • Assuming a lower percentage fee is always the better deal regardless of services included.
  • Failing to check whether the fee decreases on a sliding scale as your balance grows.

Conclusion

Request the full, layered cost — advisor fee, any flat charges, and underlying fund expenses — before comparing advisors on price. The lowest headline number is not always the lowest total cost.
