What is a good wealth management fee?

Good day, I'm curious to know what constitutes a fair and reasonable wealth management fee in the current financial landscape. As someone looking to entrust my assets to a professional for management, I'm keen on understanding the factors that influence the setting of such fees and how they align with industry standards. Furthermore, I'm interested in learning whether these fees vary based on the size of the portfolio, the complexity of the investment strategies employed, or the level of personalized service offered. Could you please provide some insights on this matter?
