Loan repayment strategy: Cardiology vs Internal Medicine

Cardiology

Usually better to refinance

With 6 years of training counting toward PSLF, cardiologists need only 4 more attending years to reach forgiveness — making PSLF worth running the numbers for, especially at academic centers. However, the $580K median salary means IDR payments are high, limiting the forgiven amount. PSLF is most compelling for academic cardiologists earning $350–450K.

For cardiologists in private practice or cardiology groups earning at or above the $580K median, aggressive payoff after fellowship is typically the dominant strategy. At this salary, $235K of debt can be eliminated in 3–4 years with focused payments.

Internal Medicine

Strong PSLF candidate

Most internal medicine physicians work at academic medical centers, VA hospitals, or nonprofit health systems — all PSLF-qualifying employers. With a 3-year residency counting toward the 120-payment requirement, IM physicians can reach forgiveness just 7 years into attending practice.

Refinancing makes more sense if you're heading into private practice or a for-profit setting where PSLF doesn't apply. With an attending salary around $310K, aggressive payoff over 7–9 years is very achievable.
