If someone asks you what your financial advisor charges, you probably quote the advisory fee — 0.85%, 1.0%, 1.25%, whatever it is. That number is usually only a fraction of what you’re actually paying. The gap between headline fee and all-in cost can easily exceed another full percentage point per year, and over a long investing horizon, one percentage point is a career-changing amount of money. Here’s how to actually calculate it.

The layers

Every dollar you invest passes through one or more of these layers. Each takes a small cut, and the cuts compound:

Layer 1 — Advisory fee. The headline number. The advisor’s (or firm’s) charge for managing your account. Typical range: 0.25%–1.5% per year. Usually billed quarterly.

Layer 2 — Underlying fund expense ratios. Every mutual fund and ETF you hold has its own expense ratio, deducted from the fund’s returns before you ever see them. Passive index ETFs: 0.03%–0.10%. Actively managed funds: 0.50%–1.25%. Alternative or multi-strategy funds: 1.5%–3%+ (sometimes with additional performance fees).

Layer 3 — Platform or wrap fees. Some advisory arrangements include a separate “platform,” “wrap,” or “custodial” fee — an infrastructure surcharge on top of the advisory fee. Typical range: 0.10%–0.50%.

Layer 4 — Transaction costs. Historically significant, mostly vanished for ETFs and stocks at major custodians (Charles Schwab, Fidelity, etc. charge $0). Still present for some mutual fund share classes ($20–50 per trade) and embedded in bond bid-ask spreads.

Layer 5 — Commissions and loads. If your advisor sells commissioned products — A-share mutual funds with front-end loads, annuities, insurance — the commission is typically 3%–8% of the amount invested, paid once, taken out of principal. Trail commissions on annuities continue annually.

A real-world calculation

Let’s compare two portfolios, both $1,000,000.

Portfolio A — fee-based firm, actively managed funds:

| Layer | Cost | |---|---| | Advisory fee | 1.00% | | Weighted fund expense ratios (actively managed) | 0.75% | | Platform/wrap fee | 0.15% | | All-in | 1.90% |

Annual dollar cost: $19,000.

Portfolio B — fee-only RIA, low-cost index ETFs:

| Layer | Cost | |---|---| | Advisory fee | 0.85% | | Weighted fund expense ratios (index ETFs) | 0.08% | | Platform/wrap fee | 0 | | All-in | 0.93% |

Annual dollar cost: $9,300.

The difference is $9,700/year — 0.97% annually. Compounded at a 7% real return over 20 years, that’s roughly $490,000 in foregone wealth. Over 30 years, closer to $900,000.

How to calculate yours

  1. Pull your last statement. List every holding with its ticker or identifier.
  2. Look up the expense ratio of each. Morningstar, the fund company’s website, or the prospectus all show it.
  3. Weight by portfolio percentage. Sum weight × expense_ratio across all holdings. That’s your blended fund expense ratio.
  4. Add the advisory fee — from your fee schedule, not just the marketing page.
  5. Ask your advisor, in writing, whether there are any platform, wrap, custodial, or administrative fees beyond the advisory fee.
  6. Identify any commissioned products — annuities, insurance-wrapped investments, A-share funds. Get the commission schedule.

Your all-in cost is the sum.

What’s a reasonable number?

For a typical diversified investor working with a full-service fiduciary advisor managing an IRA + taxable account using low-cost ETFs, all-in costs under 1.0% are achievable and common. Under 0.75% is possible for larger balances with tiered fee schedules.

All-in costs of 1.5%–2.0% are not inherently wrong — complex situations (concentrated stock management, multi-entity structures, private investments, estate coordination) can justify more — but they should come with a clear articulation of what the additional cost buys.

All-in costs above 2.0% deserve real scrutiny. At that level, the math starts requiring meaningfully above-benchmark returns just to break even with a lower-cost alternative, and above-benchmark returns are, on average, not delivered.

The disclosure tell

An advisor who hands you a clear, one-page summary of all five layers with specific numbers is demonstrating a particular kind of confidence. An advisor who says “let’s focus on performance, not costs” is telling you something else entirely.

Wilco’s all-in

For context: our advisory fee is 0.85% per year of assets under management. There are no platform fees, no commissions, no product kickbacks, no wraps. We use low-cost ETFs with weighted expense ratios typically in the 0.05%–0.15% range. Most clients’ all-in cost works out to under 1.0% annually, with the underlying fund costs being substantially less than a typical active-management arrangement.
