Fiduciaries, particularly financial advisors, typically earn their compensation through a percentage of the assets they manage on behalf of their clients. This fee, known as the Assets Under Management (AUM) fee, generally ranges from about 0.5% to 1.5% annually, depending on the size of the portfolio and the specific firm. For example, a client with a $100,000 investment might pay around 1%, equating to $1,000 per year. As the assets grow, the percentage often decreases due to tiered fee structures. This fee structure aligns the fiduciary's interests with those of the client, incentivizing the advisor to grow and protect the client's assets over time.
