Understanding Interest Capitalization

One of the biggest surprises for graduates is their loan balance being higher than what they borrowed. This happens because of interest capitalization.

⚠️ Example: The Hidden Cost

$30,000 unsubsidized loan at 7% for 4 years of school:
Interest accrued: ~$8,400
New balance at graduation: $38,400
You now pay interest on $38,400, not $30,000!

Pro tip: If you can, make interest-only payments while in school to prevent capitalization.

Frequently Asked Questions

Should I pay off student loans or invest?

Compare your loan interest rate to expected investment returns. If your loans are at 6% and you expect 8% returns, investing (after meeting minimums) may make sense.Always contribute enough to get your full 401(k) match first.

How do I qualify for Public Service Loan Forgiveness (PSLF)?

Work full-time for a government or non-profit employer, make 120 qualifying payments on an income-driven plan, and have Direct Loans. After 10 years, remaining balance is forgiven tax-free.

Should I refinance my student loans?

Refinancing can lower your rate if you have good credit and stable income. However, refinancing federal loans into private loans means losing access to income-driven plans, forgiveness programs, and pandemic protections. Usually only refinance if you don't need federal benefits.
