Investment Fee Calculator Canada (MER)
A 2% fee sounds small because it is quoted on the balance, not on your return. Charged every year on a growing portfolio, the difference between a 2% mutual fund MER and a 0.50% low-cost portfolio compounds into six figures. This calculator puts both fees on the same investments so you can see your personal number.
The calculator subtracts each fee from the gross return and compounds monthly. Real MERs are charged inside the fund on the average balance; the effect shown here is the standard approximation used for comparisons.
How it works
In the example below, both portfolios earn the same 7% before fees and receive the same contributions. The only difference is the annual fee, and after 25 years it is worth $234,154.15. Fees are the most predictable part of investing: returns are hoped for, but the MER is charged in good years and bad.
In Canada, a traditional equity mutual fund MER around 2% to 2.3% remains common, a robo-advisor portfolio typically costs about 0.4% to 0.7% all-in, and a self-built ETF portfolio can cost 0.10% to 0.25% in MERs. Advice can be worth paying for; this calculator simply makes its price visible.
Worked example
The calculator’s own output comparing a 2.00% fee with a 0.50% fee on identical investments:
| Item | Amount |
|---|---|
| Starting amount + monthly | $100,000.00 + $500.00 a month for 25 years at 7% before fees |
| Final value at a 2.00% fee | $645,883.90 |
| Final value at a 0.50% fee | $880,038.05 |
| Kept by choosing the lower fee | $234,154.15 |
Frequently asked questions
What is MER in Canada?
The management expense ratio is the total annual cost of a fund, expressed as a percentage of its assets, including management fees, operating costs and trailing commissions. It is deducted inside the fund, so it never appears as a bill.
Do lower fees guarantee better results?
No fund guarantees results, but decades of data (including SPIVA Canada scorecards) show most high-fee active funds underperform their benchmark index over long periods, largely because of the fee gap this calculator shows.
Is a financial advisor’s fee the same as an MER?
Not always. Some advisors charge a separate asset-based fee (often around 1%) on top of product costs; others are paid by trailers inside the MER. Ask for your total cost of investing in writing, in percent and in dollars.
What is a trailing commission?
An ongoing payment from the fund company to the advisor or firm that sold you the fund, included in the MER. Since 2022, trailing commissions are banned on discount brokerage accounts in Canada.
How do I find my fund’s MER?
On the fund’s Fund Facts document and in your annual account statement, which must show your personal rate of return and total charges under Canadian disclosure rules (CRM2, with expanded total cost reporting phasing in).
