Common Questions

Should I pay off debt or invest?
If your debt interest rate exceeds your expected after-tax investment return, pay off debt first — it's a guaranteed return equal to your interest rate. Credit card debt at 20–22% APR almost always beats investing, since long-run stock market returns average 7–10% annually before tax. Debt below 4–5% APR may warrant investing instead, especially in tax-advantaged accounts.
What's the break-even interest rate?
The break-even is your expected after-tax investment return. At an 8% gross return in a 33% tax bracket, your after-tax return is roughly 5.4%. Any debt above 5.4% APR should be paid off before investing in taxable accounts. For TFSA or Roth IRA contributions, you keep more of the gain — which raises the break-even slightly.
Does employer matching change the answer?
Yes — always capture employer matching first, before paying extra on debt. A 50% employer match on your contribution is an immediate 50% return on that dollar before any investment growth. No debt payoff strategy beats that. Capture the full match, then apply the debt-vs-invest math to remaining dollars.
Is paying off debt really the same as investing?
Paying off debt delivers a guaranteed, risk-free return equal to the interest rate you avoid. Investing delivers an expected return with real volatility — markets can drop 30–40% in a given year. For high-interest debt, the guaranteed return almost certainly beats the risk-adjusted investment return. For very low-rate debt, the long-run expected return from a diversified portfolio likely wins.
