Pay off student loans or invest?

2 min read

The choice is not debt or investing in the abstract. It is forgiveness eligibility, employer benefits, after-tax loan cost, risk, and your need for cash-flow freedom.

THE DECISION ORDER

1 · Preserve forgivenessIf PSLF is the plan, make required qualifying payments; extra principal generally reduces the amount that could be forgiven.
2 · Take the matchCapture an employer retirement match before comparing optional debt payments with optional investing.
3 · Eliminate toxic debtCredit cards and other high-rate balances usually outrank additional market risk.
4 · Compare the remainderA loan payoff earns a guaranteed return equal to avoided interest; investment returns are uncertain and tax treatment matters.

For federal loans around 6%–8%, physician-finance guidance often favors using tax-advantaged retirement space and then directing substantial cash to the debt—or splitting the surplus when either extreme feels too costly. Refinancing federal loans is irreversible: private refinancing ends federal IDR and PSLF access. Refinance only after deciding those protections no longer have value.

The 2026 employee deferral limit is $24,500 across 401(k)/403(b) plans, while an eligible governmental 457(b) generally has a separate limit. The 2026 combined Traditional/Roth IRA limit is $7,500 for someone under 50.

Your next steps

  1. Write down the loan path: forgiveness, federal payoff, or private refinance.
  2. Capture the full employer match.
  3. Set one monthly split between extra principal and investing, then review it annually.

Planning questions

  1. Are you pursuing forgiveness, and what evidence supports that path?
  2. After the employer match and required payments, what monthly debt-versus-investing split fits your rate, taxes, risk tolerance, and cash-flow goals?
