Invest or Pay Down Debt? A Practical Canadian Framework
Every dollar of surplus income can only be used once. Directing it at debt produces a certain, tax-free saving. Directing it at investments produces an uncertain return that may be larger.
Start with the interest rate
Debt costing more than a realistic long-run investment return is usually repaid first. Credit cards, unsecured lines of credit and payday-style borrowing fall clearly into this group.
Then adjust for tax and matching
Debt interest is generally paid with after-tax dollars, so its effective hurdle is higher than it looks. On the other side, an employer match or an RESP grant can amount to an immediate return that repayment cannot match.
Finally, account for how you will actually behave
A plan that reduces anxiety and gets followed usually outperforms an optimal plan that gets abandoned. Some households prioritise being debt-free before retirement even when a spreadsheet says otherwise — and that can be a legitimate, considered choice.
Frequently asked questions
Should I invest or pay down my mortgage?
With a low-rate mortgage and a long time horizon, many Canadians do both. The balance depends on your rate, marginal tax rate, available registered room, risk tolerance and how important being mortgage-free is to you.
What should I do with extra savings each month?
Confirm your emergency reserve, clear high-interest debt, capture any employer match or grant, then direct the remainder toward long-term goals through appropriate registered accounts.
