Advisor Fee Impact
Illustrative ending balance difference from advisory fees vs same gross return without fee drag.
About this calculator
The Advisor Fee Impact calculator illustrates how a recurring advisory fee compounds against your portfolio over time by comparing two hypothetical ending balances: one that grows at your full Gross Return (before fee), and one reduced every year by the Total Advisory Fee before compounding. Both Starting Portfolio and Gross Return matter enormously here, in different ways: Starting Portfolio is a straight multiplier on both ending balances, since every dollar of principal is scaled by the identical compounding factor in both scenarios, while Gross Return is what makes the fee-drag comparison itself dramatic — because both ending balances are computed by raising (1 + rate) to the power of your Years Invested, even a modest change in the assumed annual return compounds into a large difference in ending dollars over a multi-decade horizon, which is exactly the mechanism behind why a seemingly small percentage-point fee can foreclose so much wealth.
The Difference output is the illustrative cost of the fee: it is not the value of any advice, tax-loss harvesting, rebalancing discipline, or behavioral coaching an advisor might provide, so a large Difference figure does not by itself mean the fee was a bad deal — it only shows the pure mathematical cost of that percentage being deducted annually before compounding, all else held equal. Because both scenarios assume the same constant gross return every year, this calculator does not model market volatility, sequence-of-returns risk, or any change in behavior a fee-paying investor might make differently than a self-directed one.

How to Use This Calculator
- Enter your starting investable portfolio value.
- Set the number of years you plan to remain invested.
- Enter the expected gross annual return before advisor fees.
- Set the total advisory fee percentage (AUM-based fees are typically 0.5-1.5% per year).
- Review the portfolio ending value with and without the fee drag, and the total wealth foregone due to fees over the entire period.
- Use this to decide whether a low-cost index fund approach or robo-advisor could improve long-term outcomes.

Frequently Asked Questions
What does the 'wealth foregone' figure represent?
The Difference (Wealth Foregone) output is the gap between your projected Ending balance at your full Gross Return and the Ending balance after your Total Advisory Fee is deducted every year before compounding. It illustrates the pure mathematical cost of a recurring percentage fee compounding against your portfolio over your chosen time horizon — it is not a judgment about whether the advisor's services were worth that cost.
How does a 1% annual fee cost so much over decades?
Because the fee is deducted every single year before the remaining balance compounds again, so you lose not just that year's fee but all the future growth that fee itself would have earned. Over a 30-year horizon, this compounding-on-compounding effect can turn what looks like a small annual percentage into a very large share of your total ending wealth, which is exactly what the Ending (after fees) versus Ending (no fee drag) comparison is designed to show.
Does this calculator account for the value an advisor provides?
No — it only models the mathematical cost of the fee percentage compounding against your portfolio assuming both scenarios earn the identical gross return every year. It does not attempt to quantify tax-loss harvesting, rebalancing, behavioral coaching, or other services an advisor might provide that could offset or exceed the fee drag shown here.
Why does the projection use the same gross return for both scenarios?
Holding the Gross Return (before fee) identical in both the fee and no-fee scenarios isolates the fee itself as the only variable being tested, which is what makes the Difference output a clean measurement of fee drag rather than a comparison muddied by different assumed investment performance. In reality, a real advisor's actual investment choices could produce a higher or lower gross return than a self-directed alternative, which this calculator does not attempt to model.
