How compounding works, and why fees matter so much

A small fee difference of 0.5% per year might not sound like much. Over 30 years, it can mean tens of thousands of dollars. The math, illustrated simply.

What compounding means

Compounding is earning returns on your returns. If you invest $10,000 and earn 6%, you have $10,600 after year one. In year two, you earn 6% on $10,600, not just on your original $10,000. Over time, this snowball effect is dramatic: that $10,000 grows to $57,435 over 30 years at 6%, even with no additional contributions.

How fees eat into compounding

A 1% annual fee doesn't just cost you 1% of your money each year; it reduces your effective return from 6% to 5%, which dramatically changes the compounding math. That same $10,000 at 5% for 30 years grows to $43,219 instead of $57,435, a difference of $14,216 from a seemingly small 1% fee. The higher the balance and the longer the horizon, the more damaging fees become.

The difference between 1% and 1.5% in fees

For an employee contributing $400 per month over 30 years at a 6% gross return, a plan with 1% all-in fees results in approximately $333,000. The same plan with 1.5% fees results in approximately $304,000. That's a $29,000 difference over a career, not from investment performance, just from fees. Lower-cost ETF-based plans like LINK's are structured to keep this drag as small as possible.

What 'all-in fees' means and why it matters

Some providers advertise a management fee of 0.5% while the actual all-in cost (including operating expenses, HST, platform fees, and advisor fees) is 1.5% or more. The only number that matters is the total expense ratio on your account: everything you pay annually, as a percentage of your balance. Your LINK member portal shows this clearly.
