Financial Planning / The Compound Effect
The 3% You Cannot See
| 4 min | By Heath J. Harris
Vanguard quantified what a real advisor is worth. The answer is about three percent a year, and most of it comes from one specific place.
Here is a number more people should know.
Vanguard, the largest direct-to-investor broker in the world, estimates that a disciplined advisor relationship adds about three percent per year in net returns for the typical client. Every dollar a client moves to an advisor is a dollar that leaves Vanguard's platform, so they have no incentive to inflate the figure. They published it anyway, and they have been updating the math for more than a decade.
Three percent does not sound like much in isolation. The compounding does.
A million-dollar portfolio earning 7% over twenty years grows to roughly $3.87 million. The same portfolio earning 10% over twenty years grows to roughly $6.73 million. The difference is about $2.86 million. That is the kind of number that funds a grandchild's education, a second home, or the freedom to retire two years sooner without changing how you live.
Where the 3% comes from
Vanguard broke the three percent into seven specific behaviors. The numbers below are their estimates, and they are situational, meaning some clients get more value from one piece and less from another.
- Behavioral coaching: up to 200 basis points. This is the biggest piece by far. It is the value of not selling in March of 2020, not chasing tech in late 2021, not piling into cash at 5% yields just before the curve normalizes. It is the value of the advisor who picks up the phone on the worst Tuesday of the year.
- Spending strategy in retirement: up to 110 basis points. The order you draw from taxable, tax-deferred, and Roth accounts matters more than most people realize. So does the timing of Social Security.
- Asset location: up to 75 basis points. Putting the tax-inefficient assets in the tax-advantaged accounts. Putting the long-duration growth in the Roth. Small details, real dollars.
- Cost-effective implementation: up to 30 basis points. Lower expense ratios, smarter share class selection, fewer hidden frictions.
- Rebalancing: up to 35 basis points. Selling what went up, buying what went down, on a schedule, without flinching.
- Suitable asset allocation and total-return investing: harder to put a single number on, but real, and especially valuable when income needs are high and yields are not.
That is also why this number is not automatic. The three percent is available. It is not guaranteed. It shows up for clients who actually use the relationship. Clients who call before they trade. Clients who let us pull the tax projection before December. Clients who tell us when something changed at home so we can update the plan before it is overdue.
The full paper, including the methodology behind each component, is published openly by Vanguard's institutional research team: Putting a Value on Your Value: Quantifying Vanguard Advisor's Alpha. Worth bookmarking.
When we describe ourselves as fee-only fiduciaries at Compound Advisory, that is what we mean in practical terms. We are not on commission for any specific product. Our job is to be worth our fee three times over, and the Vanguard research is one of the cleanest frameworks anyone has built for understanding how that math actually works.
If you have not seen a written summary of what your current advisor relationship is delivering against those seven categories, that is a conversation worth having. With us or with whoever sits in that seat for you.
The 3% is not a marketing number. It is a working number. We treat it that way.
