Should I pursue PSLF or pay off my student loans aggressively?

How does PSLF work for a physician?

PSLF forgives the remaining balance on your Direct Loans after 120 qualifying monthly payments made while you work full time for a qualifying employer, which means government or a 501(c)(3) nonprofit. The payments have to be on a qualifying plan, which for most physicians means an income driven plan. Forgiveness under PSLF is not taxed as federal income.

Residency and fellowship count if the hospital qualifies, and most academic and nonprofit hospitals do. That is the part that makes PSLF so strong for physicians. A PGY 3 on an income driven plan makes 36 or more small payments that count the same as an attending's payments. Every year of training at a qualifying hospital is a year of the 10 year clock run at a resident salary.

Full time for PSLF means an average of at least 30 hours per week for the qualifying employer. The 120 payments do not have to be consecutive. If you leave a qualifying employer for a few years and come back, you keep credit for the payments you already made. Only Direct Loans qualify, so if you have older FFEL or Perkins loans, you would need to consolidate them into a Direct Consolidation Loan first, and only payments made after the consolidation count.

For a physician with six figures of debt, this is the largest single decision about the loans, and refinancing takes the PSLF option away for good. Once you refinance federal loans into a private loan, there is no path back to PSLF.

How do I run the math on PSLF versus paying it off?

Run it with your own numbers. Two illustrations show why the answer swings so much.

A pediatrician finishes a 3 year residency with 36 qualifying payments made and $375,000 of loans at 7 percent. The attending salary is $240,000 and rises 3 percent a year. On an income driven plan at roughly 10 percent of discretionary income, the payments over the remaining 84 months come to about $184,000. Refinancing the same $375,000 at 5 percent over 10 years costs about $3,976 a month, or about $477,000 total. PSLF saves roughly $293,000 before counting the time value of money, which only widens the gap.

Now flip it. An orthopedic surgeon finishes a 5 year residency plus a 1 year fellowship with 72 qualifying payments and $250,000 of loans. The attending salary is $550,000. On an income driven plan the payments are large because the income is large, and the remaining 48 payments might total $230,000 against a $250,000 balance. The savings are thin, and they come with 4 more years of employment restrictions. Refinancing and paying aggressively could cost about the same with none of the strings.

The pattern: PSLF favors lower earning specialties with high debt and long training. It favors less the higher your attending income and the smaller your balance.

What can disqualify me?

The common failures are all paperwork and loan type, not effort.

First, wrong loan type. Only Direct Loans qualify. If any of your loans are FFEL or Perkins and you never consolidated, payments on those loans do not count. Check your loan types on the Federal Student Aid site before assuming anything.

Second, wrong repayment plan. The standard 10 year plan technically qualifies, but on that plan you would pay the loan off in 120 payments anyway, so there would be nothing left to forgive. You need an income driven plan for PSLF to have value. Make sure you are enrolled in one and that you recertify your income every year. A missed recertification can push you into a different payment amount and cost you qualifying months.

Third, wrong employer certification. Submit the PSLF employment certification form every year, not just at the end. Annual certification catches problems early, like an employer whose tax status does not qualify or months that did not count. Waiting 10 years to discover a problem is the worst version of this.

Fourth, refinancing. This is the irreversible one. The day you refinance federal loans into a private loan, PSLF is gone permanently. Do not refinance while PSLF is still on the table unless you have decided against it with full information.

When should I decide?

Decide by the end of PGY 1 if you can. The earlier you commit to a path, the more each path pays.

If PSLF is your path, get on an income driven plan immediately, certify your employment every year, and never refinance. Every qualifying payment you make as a resident is a payment at the lowest income you will ever have.

If aggressive payoff is your path, refinance when your rate and income justify it, usually as an attending or late in training. Do not refinance during residency just because the rate looks tempting. The rate improvement is small relative to what you give up, and resident life is when PSLF payments are cheapest.

If you are unsure, stay federal and stay on an income driven plan. That keeps both options open. You can always refinance later. You can never unrefinance.
