Student Loan Repayment: The Complete Playbook

You did not get here by being irresponsible

Most physicians finish training with six figures of debt and no plan for it. That is not a character flaw — it is the arithmetic of earning $60,000 for three to seven years while interest compounds daily, taught by a curriculum that covered the renal tubule in more detail than your own loans. This playbook is the conversation nobody had with you. It covers the four decisions that determine whether your debt costs you $200,000 or $500,000: how the interest actually accrues, which income-driven plan to be on, whether PSLF is worth pursuing, and whether to refinance — the one move you can never undo. Work through it once and you will out-reason the loan-servicer rep whose incentives are not aligned with yours.

$55/day

At a $300,000 balance and a 6.8% weighted rate, your loans accrue roughly $55 every day — about $1,700 a month — before you pay a cent. During residency, an income-driven payment of $0–$400/month often does not even cover that, so the balance grows while you do everything right. This is the engine behind every decision that follows. It is also why the instinct to “just pay it off fast” is sometimes exactly wrong: if a large chunk is headed for tax-free PSLF forgiveness, every extra dollar you throw at principal is a dollar you will never get back. The math, not the moral discomfort of carrying debt, has to drive this.

Capitalization

Capitalization is when accrued, unpaid interest is added to your principal — so you begin paying interest on that interest. It is triggered by specific events: leaving an income-driven plan, certain consolidations, exiting forbearance, or losing eligibility for a plan.

Before plans and forgiveness, understand the one mechanic that silently enlarges the debt.

Why it matters: A resident who accrues $18,000 of unpaid interest over three years and then triggers capitalization adds that $18,000 to principal permanently. At 6.8%, that single event costs roughly $1,200/year in new interest — forever, until the loan is gone. The defensive move is simple: avoid unnecessary plan changes, consolidations, and forbearances, and never let a deferment lapse into capitalization by accident.

The income-driven menu, as of 2026

After the SAVE plan was struck down in the courts and began phasing out, the live menu is IBR, PAYE, and the new Repayment Assistance Plan (RAP). All count toward PSLF, and your forgiveness count carries between them — so switching plans does not reset your progress. Confirm the current menu and your eligibility on studentaid.gov; these rules are moving.

How much PSLF is worth to you

The refinancing trap

Refinancing federal loans — the move you can never take back

A private lender offers a clean-looking rate and a slick app, and refinancing your federal loans feels like the responsible, grown-up thing to do. For a physician with any chance of PSLF, it is usually the single most expensive mistake available. The moment federal loans become private, they are private forever — there is no path back to federal. You permanently lose PSLF eligibility, income-driven payments, the $0 payments of training years, deferment and forbearance protections, and death-and-disability discharge. Residents are the most-targeted and worst-positioned group: their balances are large, their incomes are about to jump, and a few years of $0–$400 IDR payments plus tax-free forgiveness almost always beats a 'good' private rate.

How to avoid it: Refinance federal loans only when ALL of these are true: you have definitively ruled out PSLF, you will not work for a nonprofit or government employer, and you have a stable attending income with an emergency fund already in place. For most physicians that means: do not refinance during residency, full stop. If you have private loans already, refinancing those (private → private) is a different, lower-stakes decision and can be worthwhile.

PSLF vs. refinance — the break-even

R3 with $280,000 federal at 6.8%. Path A: stay federal, finish PSLF (4 years training + 6 attending years at a qualifying employer). Path B: refinance to 4.5% private and pay it off over 10 attending years.

Bottom line: Path A (PSLF) costs roughly $168,000 of payments; Path B (refinance) costs roughly $348,000. The PSLF path is ~$180,000 cheaper here — and that gap is tax-free. Refinancing only pulls ahead if you are certain you will not work for a qualifying employer. Run your own numbers with the PSLF value calculator; the answer flips with your balance, rate, and the employer you choose.

The employer switch

What to do this month

• PSLF forgives federal Direct loans after 120 qualifying payments at a qualifying employer on a qualifying plan — tax-free under current law.
• Never refinance federal loans into private if there is any chance of working at a nonprofit employer. It is permanent.
• File the Employment Certification Form annually and every time you change jobs. Do not rely on memory or the servicer.
• Lower IDR payments via 403b contributions and HSA contributions — they reduce AGI.
• The PSLF Help Tool at studentaid.gov is the official tracker. Reconcile their count with your records every year.

Do this next: File the PSLF Employment Certification Form for your current employer this week — even if you have filed before. It is the single best protection against servicer accounting errors.
