Compare two investment costs
Defaults compare a 0.20% low-cost option with a 1.20% higher-cost option. They are examples, not market averages.
Option A · lower cost
Option B · higher cost
Transparent calculation method
Each month, the calculator adds the contribution, applies the gross monthly investment return, then deducts the effective monthly percentage fee and one-twelfth of the flat annual fee. An upfront fee is deducted from the starting balance once. The no-fee path uses the same contributions and gross return.
Returns are assumed constant only to isolate the effect of fees. Real markets vary, taxes are excluded, and some fees are reflected inside a fund’s reported performance rather than appearing as a separate cash charge.
Which fees belong in each field?
| Fee type | Where to enter it | Common mistake |
|---|---|---|
| Fund expense ratio | Annual percentage | Treating it as a one-time charge |
| Advisor/platform AUM fee | Add to annual percentage if not already all-in | Double counting an all-in fee |
| Sales load or entry charge | Upfront percentage | Ignoring that less principal starts compounding |
| Account/subscription cost | Flat annual fee | Expressing a fixed dollar fee as a percentage |
| Trading spreads/taxes | Not modeled here | Assuming every cost is an AUM fee |
Why a side-by-side comparison is more useful
The first ranking result compares only a term, one balance, one return and two percentage fees. BeCoin supports ongoing contributions, a sales load and flat annual costs, then separates direct fees from forgone growth. This lets you compare a low-cost ETF, managed fund, robo-advisor or human-advice structure using the fees actually disclosed to you.
Authoritative benchmark: the SEC’s current Investor.gov fee guide illustrates $100,000 growing at 4% for 20 years. Its approximate ending values are $208,000 with a 0.25% annual fee, $198,000 with 0.50%, and $179,000 with 1.00%. BeCoin keeps its own defaults explicitly illustrative and lets you enter the costs in your actual disclosure.
Use compound interest for savings scenarios, review S&P 500 historical returns, or compare BeCoin bull, base and bear forecasts for 100+ assets.
Connect fees to the rest of the investment decision
A fee comparison is most useful beside a long-term wealth target, a dividend reinvestment projection, and a doubling-time check. Compare assumptions with the historical investment calculator, market-crash history, inflation calculator, Coast FIRE calculator, and 401(k) balance benchmarks. For market-specific context, review S&P 500 forecasts, Apple forecasts, the full tools directory, and BeCoin’s risk disclaimer.

Frequently asked questions
How much does a 1% investment fee cost over time?
It depends on the balance, contributions, gross return and term. The result includes fees deducted directly plus the future growth those dollars could have earned.
What fees should I include?
Include applicable fund expense ratios, advisory/platform AUM fees, upfront loads and recurring flat charges. Avoid double counting an all-in quote.
Is an expense ratio charged only on contributions?
No. It is generally expressed as an annual percentage of fund assets and reflected in returns over time.
Do lower fees always mean a better investment?
No. Fees are certain, but risk, performance, service and tax outcomes vary. Compare like-for-like strategies and what each fee buys.
