Common mistakes to avoid

- Forgetting that interest accrues during in-school and grace periods.
- Not taking advantage of the non-repayment assistance plan (NRAP) if struggling financially.
Frequently asked questions
What is the government repayment assistance plan?
The Repayment Assistance Plan (RAP) lets you cap your Canada Student Loan payment at a percentage of your income. If you qualify, the government may cover the difference and even reduce principal after 10 years.
Should I invest or pay off student loans?
If your loan rate is above ~5%, paying it off is a guaranteed "return" equal to your rate. If your loan rate is below your expected investment return (e.g., 3% loan vs 7% market), investing may win mathematically, but debt-free peace of mind has value.
