Fiduciary.

In plain English

A fiduciary is bound by law to act in the client's best interest, putting the client's needs ahead of their own (including their own compensation). Registered Investment Advisers (RIAs) are fiduciaries under SEC and state rules. Brokers traditionally were not; they followed the lower 'suitability standard,' which required only that an investment be suitable for the client, not necessarily the best available option. The SEC's Regulation Best Interest (Reg BI, effective 2020) raised the bar for brokers but stopped short of making them full fiduciaries.

01Why it matters

The difference between a fiduciary and a non-fiduciary advisor is the difference between 'this is the best option available to you' and 'this is a reasonable option that pays me a commission.' In practice, that gap can compound to tens of thousands over a career through higher-fee mutual funds, embedded sales charges, and other products with commissions baked in. A question that surfaces the answer quickly: 'Are you a fiduciary, in writing, at all times?' The 'at all times' qualifier matters because some advisors operate under fiduciary duty for one piece of business and the suitability standard for another.

02The math, step by step

Consider a $500,000 retirement account held for 30 years at a 7% average return. A low-cost index allocation might charge a blended expense ratio of about 0.05% per year. A commission-based mutual fund mix might charge a 5.75% front-end sales load plus an annual expense ratio of about 0.60%. Holding everything else equal, the higher-cost mix ends with roughly $100,000 less than the low-cost mix purely due to fees. The fiduciary standard does not dictate which product is right for any individual; it constrains an advisor with a fiduciary duty from recommending a higher-cost option when an equally suitable lower-cost one exists.
