Comparison
1% vs 0.2% Investment Fees: How Much Difference Can It Make?
What happens in an illustrative model when two otherwise identical investment paths differ only in the annual percentage fee?
The short answer
In this illustrative model — identical contributions, identical horizon, identical assumed gross return, and only the annual percentage fee different — the 0.20% path ends US$81,019.15 higher than the 1.00% path after 30 years.
That gap is close to twice the US$41,000.48 difference in money actually deducted, because each deduction also stops earning. It is a model output, not a forecast, and it does not establish that a lower-fee product is automatically the better one — only that the higher fee creates a hurdle.
The controlled comparison
One scenario is run twice. Everything except the annual percentage fee is held constant — the same opening balance, the same contributions on the same dates, the same horizon and the same assumed gross return. Holding all of that fixed is what allows the fee effect to be isolated; it is also what makes this a controlled model rather than a statement about any real product.

| Recurring contribution | US$500.00 |
| Contribution frequency | Monthly |
| Contribution timing | End of period |
| Horizon | 30 years |
| Assumed gross annual return | 7.00% |
| Fixed fees | US$0.00 |

The 7.00% gross annual return is illustrative: a number chosen to calculate with, not an expectation, a historical average or a claim about any market. Neither fee level is described or implied to be high, low or typical.

Why the difference grows
The two figures in the last row are not the same size, and the reason is the whole point of the comparison. US$41,000.48 more was deducted along the way; the ending values are US$81,019.15 apart.
- A percentage fee repeats. It is charged again on every charge date, for thirty years.
- Later balances are larger, so the same percentage takes a larger amount from them.
- Each amount deducted stops participating. From the day it leaves, it is not there to gain — or, on a falling path, to lose.
The mechanism, including why the second component is signed and behaves differently on a falling path, is set out in How Investment Fees Compound Into Lost Wealth. This page measures the size of the difference rather than re-explaining its cause.
The return hurdle
How much additional gross annual return would the 1.00% path need to reach the 0.20% path's ending value, with every other assumption unchanged? The model solves for it rather than estimating it:
0.86 percentage pointsmore gross return per year, in this model, just to finish level
Note that this is larger than the 0.80 percentage points difference between the two fee levels. Subtracting one fee from the other understates the requirement, because the percentage fee is charged against a balance the extra return has already grown.
- It is a mathematical requirement under controlled assumptions, not a forecast.
- It is not evidence that a higher-cost option can actually earn that extra return.
- It says nothing about the risk that would be taken in trying to, and it is not a recommendation to choose either option.
A lower fee is not automatically better
This comparison prices one variable. Two real options that differ in cost can also differ in advice, behavioural support, asset allocation, risk management, tax handling, administration, access, implementation quality, service, and what happens when something goes wrong. None of that is in the arithmetic above, and none of it can be.
A higher fee creates a hurdle. It does not by itself establish that the higher-fee option is worse. The question the model cannot answer is whether the additional value received justifies the additional cost — and that is a judgement about a specific option, for a specific person, not an output of a projection.

What this comparison does not determine
The figures on this page are outputs of a UBWHY calculation model applied to the assumptions stated above. They are not historical returns, expected returns, the performance of any investment product, or a forecast. The comparison cannot determine:
- future returns, or what any market will actually do
- expected returns — the 7.00% is an assumption entered into the model, not a projection
- tax of any kind: no wrapper, allowance, jurisdiction or rate is modelled
- inflation, which this scenario does not model at all
- product quality, or how anything is run, held or reported
- suitability for any particular person or circumstance
- whether two real options carry equal risk — identical gross return is an assumption entered, not a finding
- whether a higher-cost option will outperform
- whether additional services justify a higher fee
None of this is financial, legal or tax advice, and no product is recommended, ranked or named anywhere on this page.
Where these figures come from
Every number above is produced by Investment Fee Drag v1.0, the same calculation model behind the Investment Fee Drag Calculator, from verified test case FD-8. The scenario, the expected outputs and the tolerances live in the model's specification and are recalculated independently on every build, so a figure here cannot drift away from the calculator without failing that check.
