The 1% Fee vs. Hourly Advice: What a $500,000 Portfolio Really Costs Over Time

A 1% annual advisory fee sounds small. On a $500,000 account, that's $5,000 the first year. But because that fee is charged every year on a growing balance, and because it compounds away from your investment returns rather than just your wallet, its real cost over 10 or 20 years is far larger than most people expect.

Below is an illustrative comparison of a $500,000 portfolio under two fee structures: a 1% assets-under-management (AUM) fee taken directly from the account each year, versus an hourly planning relationship billed and paid separately, out of pocket, with the full account balance left to grow and compound untouched. AMA Financial Planning bills this hourly relationship at $250/hr, so a typical planning relationship of about 6 hours a year runs roughly $1,500 out of pocket - modest compared to the AUM fees shown below, and it's this hourly cost that is paid separately rather than deducted from the account.

10-year comparison

• At a 5% average annual return: AUM path ends near $737,000 after paying roughly $60,000 in cumulative fees out of the account. Hourly path, with no fee drag on the account itself, ends near $814,000 — a gap of roughly $78,000.

• At a 7% average annual return: AUM path ends near $890,000 (roughly $66,000 in fees paid from the account). Hourly path ends near $984,000 — a gap of roughly $94,000.

• At a 9% average annual return: AUM path ends near $1,071,000 (roughly $72,000 in fees paid from the account). Hourly path ends near $1,184,000 — a gap of roughly $113,000.

20-year comparison

• At a 5% average annual return: AUM path ends near $1,085,000 (roughly $148,000 in cumulative fees paid from the account). Hourly path ends near $1,327,000 — a gap of roughly $242,000.

• At a 7% average annual return: AUM path ends near $1,583,000 (roughly $183,000 in fees paid from the account). Hourly path ends near $1,935,000 — a gap of roughly $352,000.

• At a 9% average annual return: AUM path ends near $2,292,000 (roughly $227,000 in fees paid from the account). Hourly path ends near $2,802,000 — a gap of roughly $510,000.

These figures are simplified illustrations, not a projection for any individual account. They assume a constant annual return and a fee taken as a flat 1% of the beginning-of-year balance, neither of which happens exactly this way in the real world. The hourly path's ending balance reflects only the account itself, since an hourly planning fee is billed and paid separately rather than deducted from the portfolio; it does not depend on how many hours are billed in a given year. Actual returns fluctuate, fee structures vary by firm, and the value an advisor adds through planning, tax strategy, and behavior coaching isn't captured by a fee comparison alone.

The point isn't that AUM fees are never worth it. For portfolios that genuinely require ongoing, active discretionary management, a percentage fee can make sense. But for many households who mainly need a periodic financial planning check-in, retirement projections, an investment review, and someone to call before a big decision, paying for time rather than a percentage of assets can leave meaningfully more money compounding in your own accounts over the long run.
