In Canada, the TFSA, RRSP, and FHSA all allow investments to grow tax-sheltered, which means compounding gets a chance to work without taxes constantly draining the gains.
Here’s how compounding behaves in each account:
TFSA
- Gains grow tax-free
- Withdrawals are also tax-free
Compounding here is extremely powerful because the government never gets a slice of your growth. If you want a long-term compounding machine, this is your go-to.
RRSP
- Contributions give you a tax deduction
- Growth is tax-deferred, not tax-free
Your investments compound untouched for decades, and you only pay tax when withdrawing in retirement, usually at a lower rate. Compounding thrives because the initial tax refund lets you invest more upfront.
FHSA
- Contributions give you a deduction like an RRSP
- Growth and withdrawals are tax-free like a TFSA (As long as it’s for your first home)
This is compounding with cheat codes: deductions now, no tax later. If you’re planning to buy a home, compounding in an FHSA is very efficient.
So compounding isn’t about interest, it’s about behaviour. The math is easy. But the discipline is not.
Compounding collapses if:
- you stop contributing
- you constantly switch investments
- you panic sell during downturns
- or you keep pulling money out
Its power isn’t in big moves, it’s in steady, consistent growth over long stretches of time, so a lot like working out. It rewards people who stay calm when things look ugly and who keep investing whether the market is up, down, or sideways.
The Dark Side of Compounding
As I said earlier, compounding doesn’t care about you. It works on whatever you give it, debt included.
Credit card balances, payday loans, lines of credit… if interest is being charged exponentially, compounding is building wealth, just not for you.
If you’re carrying high-interest debt, compounding becomes your enemy. Kill that first, then let compounding become your ally.
So, start small, start early, and stay consistent
You don’t need huge money to benefit from compounding! All you need is:
- a long time horizon
- automatic contributions
- an investment strategy you stick to
- and patience
Compounding turns discipline into wealth. The earlier you let it start, the easier your future becomes. The later you start, the harder you have to work to catch up.
Don’t overthink it though. Just start. Your future self will thank you!
