How This Changes If Returns Are Better or Worse
The verdict above assumes your expected return holds exactly. Markets don't cooperate that precisely — here's the same comparison 4 points below and above it.

Scenarios
How This Usually Plays Out
- High-interest debt (credit cards, personal loans above ~15%) almost always beats investing — few realistic investments consistently outrun that rate.
- Low-interest debt (a subsidized education loan, a cheap home loan) leaves more room where investing alongside repayment can make sense.
Risks & Exceptions
When the Normal Advice Doesn't Apply
- Carrying high-rate debt while investing in something volatile is usually the worst combination — you can lose on the investment while the debt keeps compounding regardless.
Decision Framework
How to Actually Decide
- List every debt by interest rate, highest first.
- Anything above ~15–18% p.a. — pay it down before investing meaningfully.
- Below that, run the numbers using the calculator above.
