Should You Pay More Than the Minimum on Your Student Loans? The Answer Depends on Which Loans You Have — and It Might Surprise You.
Bottom line
For borrowers on income-driven repayment plans pursuing forgiveness, paying extra often makes no financial sense — and can reduce the benefit you are already on track to receive. For borrowers on standard plans or with private loans, paying extra saves real money. The right answer depends entirely on your situation.

Common mistakes
- 1Aggressively paying down federal loans while pursuing PSLF. Every extra dollar paid on a PSLF-eligible federal loan while you have a qualifying employer reduces the balance that would have been forgiven tax-free at the 10-year mark. You are spending real money today to reduce a future benefit. Run the full math — including the projected forgiven amount — before making large extra payments on federal loans.
- 2Directing extra payments to the wrong loan. If you have multiple loans, extra payments sent to your servicer may be applied to your next scheduled payment rather than specifically to the highest-interest balance. Contact your servicer in writing and explicitly request that any amount above the minimum be applied to principal on the highest-interest loan. Follow up to confirm on your next statement.
- 3Pausing retirement contributions to pay extra on student loans. For most borrowers, capturing a full employer 401(k) match is a better return than paying extra on student debt. A 50% employer match on a 6% contribution is a guaranteed 50% return before the market does anything. Most student loan interest rates do not approach that. Capture the full employer match before directing extra money to loan payments.
FAQ
If I am on SAVE with a /bin/zsh monthly payment, do those months count toward forgiveness?
Yes. A /bin/zsh required payment under SAVE counts toward your 20 or 25-year IDR forgiveness clock, and counts toward PSLF's 120-payment requirement. A /bin/zsh payment where interest also does not accrue is genuinely one of the best outcomes available for low-income federal borrowers — you are making progress toward forgiveness without spending anything.
I want to pay off my loans early. How do I make sure extra payments go to principal?
Contact your servicer in writing — through the servicer's secure message system is ideal so you have a record — and request that any payment above the minimum monthly amount be applied to principal on your highest-interest loan. Then check your next monthly statement to confirm the payment was applied as requested.
My loans are at 4%. Should I pay extra or invest?
At 4%, the math typically favors investing in a diversified, low-cost index fund for most people over long time horizons. But paying off debt has a guaranteed, risk-free return and a psychological benefit that investing does not. A common approach is to invest enough to capture the full employer match first, then split extra money between loan payoff and investing based on how much certainty you want.

What to check next
First, clarify whether you are pursuing forgiveness on your federal loans. If yes, consider stopping extra payments on those federal loans. If no, use the Federal Student Aid Loan Simulator or a student loan payoff calculator to see exactly how much you would save in interest by adding to per month. Then compare that to what the same amount invested would look like over the same period.
