Fee-only vs fee-based financial advisor: what is the difference?

By Sam’s List team · Updated November 2026

Short answer: A fee-only advisor is paid only by clients (for example an AUM, flat or hourly fee) and does not take commissions. A fee-based advisor charges client fees and may also earn commissions on products such as insurance or annuities. The names sound alike, so confirm how an advisor is paid in their Form ADV and Form CRS.

Why does it matter?

Commissions can create a conflict of interest, because pay depends on the product sold. Fee-only removes commissions but has its own incentives (an AUM fee grows when assets stay with the advisor). Neither label replaces asking how the advisor is paid in dollars.

How do you check?

  1. Read Form CRS: it states how the firm and its professionals are paid and their conflicts.
  2. Read Form ADV Part 2A, Item 5 (fees and compensation).
  3. Look the advisor up on IAPD and BrokerCheck; a broker registration means commissions are possible.
  4. Ask: “Do you or your firm receive any compensation from anyone other than me?”
