OraHold growth and deposits constant
All three scenarios share the starting amount, monthly contributions, selected contribution timing, gross return and horizon. Only the asset fee differs. This isolates the effect of the modeled fee rather than comparing unrelated investments.
The annual gross return is effective annually: monthly growth factor = (1 + return)1/12. Beginning-of-month deposits grow during that month; end-of-month deposits do not. Growth is rounded to the currency's minor unit each month. The fee is then charged after growth and that month's deposit.
Choose the fee-charging convention
For monthly-equivalent charging, annual fee fraction f becomes monthly fraction 1 − (1 − f)1/12. It is not f ÷ 12. This defines the same annual retention factor in an unrounded no-contribution model.
For year-end charging, the full annual fee is applied at projection months 12, 24 and so on. There is no accrued or prorated fee for a final partial year: an 11-month scenario has no year-end charge; an 18-month scenario has only its month-12 charge. These are explicit modeling conventions, not a claim to reproduce a fund's daily expenses or calendar cut-offs.
Two fee rates over 24 months
Start with 1,000.00, add 100.00 at each month-end, assume a 6% effective annual gross return and project 24 months using monthly-equivalent fees. Compare chosen annual asset fees of 0.25% and 1%.

| Scenario | Ending balance | Charged fees |
|---|---|---|
| No asset fee | 3,662.86 | 0.00 |
| 0.25% annual fee | 3,650.55 | 11.79 |
| 1% annual fee | 3,613.61 | 47.05 |
The ending balances differ by 36.94. Compared with no fee, the 1% scenario ends 49.25 lower, even though its charged fees total 47.05. The remaining difference reflects the effect on subsequent growth, not an additional undisclosed cash fee.
Read the product terms separately
The SEC Investor Bulletin on investment fees explains how fees reduce money left invested and why disclosures matter. This calculator models one percentage-based asset charge, not every cost of investing.
Transaction fees, fixed charges, tiers, tax, actual daily expense accrual, performance fees, rebates and changing returns are excluded. A lower modeled cost does not guarantee a better real-world outcome or identify a suitable investment. The result is neither APR nor a regulated product disclosure.
The compound-growth calculator lets you inspect contribution and timing assumptions separately. The real-return guide explains another distinct adjustment: a modeled balance after fees still is not the same as its purchasing power or its after-tax value.
Compare schedules using the same convention
Each monthly growth and fee charge rounds before the next balance is calculated. The closing ledger therefore reconciles as opening balance + contribution + gross growth − fee. Its no-fee balance can differ slightly from a separate calculator carrying unrounded balances internally.
Changing from monthly-equivalent to year-end charging changes the fee base and dates, especially when contributions are added. Compare like with like, and inspect the chosen charging schedule before treating a difference as evidence about a real account.
Common questions
Is the fee simply deducted from the annual return?
No. This model applies gross growth, adds deposits according to their timing and then charges the selected asset fee. Subtracting percentages would hide those conventions.
Why is ending-balance impact different from fees paid?
Fees remove money that would otherwise remain in later growth calculations. The ending-balance comparison includes that subsequent effect.
Does year-end mode charge for a final incomplete year?
No. It charges at projection months 12, 24 and so on, with no final partial-year accrual or proration. A real product may use different rules.
