An employer match looks like free money — and often it is. But high-MER group funds erode that advantage faster than most people realize. This calculator shows you the real numbers.
The typical Canadian group RRSP fund runs 1.8–2.5% MER. A Vanguard or iShares equivalent is 0.11–0.25%. The match is real — but so is the fee drag compounding for decades.
| Year | Group fund balance | Self-directed balance | Match value remaining | Net advantage (Group) |

The MER is buried in your fund fact sheet — not the account statement. Log into your group plan portal (Manulife, Sun Life, Canada Life, Desjardins, Great-West), look for "Fund Details" or "Fund Facts," and find the MER row. It's usually labeled "Management Expense Ratio."
Some group plans negotiate a lower institutional MER. But many — especially at smaller employers — just use the standard retail series. A 2.1% MER on a Canadian equity fund is not unusual. The equivalent iShares XIU ETF costs 0.18%.
Graded vesting means you own a growing share of the employer match each year — 20% after year one, 40% after year two, and so on. Cliff vesting means you own 0% until a fixed date, then 100% all at once.
If you leave before vesting, the unvested match disappears. The calculator discounts the match value based on your vesting period. A 50% match that vests over 3 years and you leave after 18 months is worth considerably less than it looks on paper.
Up to the match cap, contributing is almost always worth it — the match is an immediate 50–100% return. Beyond the cap, you're just holding an expensive mutual fund. If your group plan's MER exceeds ~1.5%, you're almost certainly better off with a self-directed RRSP at Questrade or Wealthsimple for any contributions above the match threshold.
The exception: some employers offer group pricing on institutional fund series at 0.4–0.9% MER. That changes the math — plug in your actual numbers.
