You are sitting in the most expensive classroom in American education, and the bill compounds while you sit in it. The median four-year cost of attendance for the medical school class of 2026 was roughly $298,000 at public schools and more than $408,000 at private ones, and most of that is borrowed money accruing interest from the day it disburses. Yet the medical student years are also the stage where financial decisions are cheapest to get right: the balances are still forming, the habits are still unset, and the compounding clock — the one working against you on loans and for you on everything else — has more runway than it will ever have again. This guide sequences six shipped foundational modules into a reading order built for exactly this stage, then names the deep-cut articles for when a module is not enough.
First, the three money problems that define these four years. Every other decision is downstream of them.
Problem one: your loans compound in the library, silently, at 8.07 percent
Direct Unsubsidized Loans accrue interest from the day of disbursement, not the day you finish training. For loans first disbursed between July 1, 2026 and June 30, 2027, the graduate and professional rate is 8.07 percent, fixed for the life of the loan. The borrowing landscape also changed on July 1, 2026 under Pub. L. 119-21 (the 2025 reconciliation act): Grad PLUS loans are closed to new borrowers, and students in professional degree programs — medicine included — face a federal cap of $50,000 per year and $200,000 aggregate.
| Federal borrowing, loans disbursed 7/1/2026–6/30/2027 | Figure |
|---|---|
| Direct Unsubsidized rate, graduate and professional | 8.07% fixed |
| Annual federal cap, professional degree programs | $50,000 |
| Aggregate federal cap, professional degree programs | $200,000 |
| Grad PLUS | Closed to new borrowers |
Example calculation
Assumptions, stated explicitly: you borrow $50,000 at the start of each of four years; every loan is Direct Unsubsidized at 8.07 percent; you make no payments during school; federal loans accrue simple interest while in school.
Year 1 interest: $50,000 × 0.0807 = $4,035 Year 2 interest: $100,000 × 0.0807 = $8,070 Year 3 interest: $150,000 × 0.0807 = $12,105 Year 4 interest: $200,000 × 0.0807 = $16,140 Interest accrued by graduation: $40,350
You walk into intern year owing approximately $240,350 on $200,000 borrowed — before residency begins.
The point is not fear. Interest accrual during school is a number you can know to the dollar today, and most students never look. Knowing it changes nothing about the loan and everything about the decisions layered on top of it.
Problem two: your credit history is written before your income exists
A credit score is built from behavior, not income. The payment history and account age you establish in M1 and M2 — on a $0 salary — are the same data a residency landlord reads in four years and a mortgage underwriter reads in eight. The two failure modes run in opposite directions: some students carry revolving balances at card rates that commonly exceed 24 percent APR, where a $3,000 balance costs roughly $720 per year in interest against no income at all; others avoid credit entirely and arrive at residency with a file too thin to rent an apartment without a cosigner.
Important
Minimum payments are designed to keep a balance alive, not retire it. A card is a payment instrument on this path, never a borrowing instrument: if the statement balance is not paid in full every month, the card is working against you at roughly three times your student loan rate.
Problem three: match season is a four-to-five-figure cliff with no paycheck behind it
Between the fall of M4 and your first intern paycheck sit residency application fees, interview travel, a relocation deposit, first month of rent in a new city, and often a car decision — commonly $3,000 to $10,000 of outflows, estimated broadly because the range is wide. The paycheck on the other side does not arrive until late July at many programs. Loan disbursements stop; expenses do not. Students who have not parked cash for this cliff bridge it with credit cards at exactly the moment problem two becomes expensive.
The sequence: six shipped modules, in an order that matters
The order below is deliberate. Early modules build the habits the later ones assume, and the final two are timed to the M4-to-intern transition rather than to today.
1. Credit Cards, Decoded — because the card arrives before the salary
Card offers reach medical students years before income does, and the terms are built for people who do not read them. Credit Cards, Decoded covers APR mechanics, utilization, account age, and why the card you open in M1 quietly matters at 40. One action: pull your free, federally authorized credit report and read every line on it.
2. Cash Parking — because your disbursement sits somewhere for months
Loan disbursements arrive in lumps and drain over a semester. Cash Parking covers where short-horizon cash should sit and why the default checking account is the most expensive choice. The difference between a near-zero checking rate and a market-rate account has recently been worth roughly $350 to $450 per year for every $10,000 parked. One action: move next semester's living-expense cash to an account that pays a market rate.
3. Inflation Basics — because a fixed debt and a rising salary are connected
Your loan balance is fixed in nominal dollars; the attending salary that eventually repays it is not. Inflation Basics gives you the real-versus-nominal frame: an 8.07 percent nominal rate against inflation running near 2 to 3 percent is a real rate near 5 to 6 percent — high enough to take seriously, low enough that panic is not a strategy. One action: restate your projected graduation balance in real terms against a first-year attending salary in your intended specialty.
4. Net Worth Basics — because negative $240,000 is a starting line, not a verdict
Most medical students have never computed their because they suspect the answer. Net Worth Basics makes the case for measuring it anyway: a physician's net worth curve is J-shaped by design, and the students who track the number from its lowest point are the ones who notice when a decision bends the curve. One action: compute your net worth once, this week, loans included.
5. Budgeting a Resident Salary — read in M4, as intern-year prep
Do not wait until July of intern year to learn what a PGY-1 stipend — typically in the $60,000 to $70,000 range — actually covers. Budgeting a Resident Salary is written for residents, and the highest-value time to read it is the spring before you become one, when the lease you sign and the car you choose are still decisions rather than facts. One action: draft your intern-year budget before rank lists are due, and let it set your rent ceiling.
6. The PSLF Decision — the single highest-stakes read before PGY-1
Most residency employers are university, public, or 501(c)(3) hospitals, which means residency payments can count toward from the very first one — but only if you are enrolled in a qualifying plan. As of July 1, 2026, the Repayment Assistance Plan (RAP) is the income-driven plan open to new borrowers: payments run 1 to 10 percent of adjusted gross income by income band, and on-time RAP payments qualify for PSLF. A resident who sits in forbearance for three years instead of enrolling forfeits 36 qualifying payments — nearly a third of the 120 required. The PSLF Decision walks the whole choice. One action: read it before your first loan payment is due, not after.
Key insight
The sequence is front-loaded with small-dollar modules on purpose. Credit and cash habits cost almost nothing to fix as a student and thousands to fix as an attending; the PSLF decision costs nothing to get right on day one and five figures to repair after three years of forbearance.
One honest note on scope: a dedicated module on medical school loans themselves — borrowing strategy under the new caps, subsidized versus unsubsidized mechanics, gap-financing decisions — is in production and not yet shipped. Until it is, the deep cuts below carry that weight.
Three deep cuts when the modules are not enough
- Federal versus private loans for medical school — the borrowing decision the $200,000 aggregate cap now forces on students whose cost of attendance exceeds it.
- Your first budget on a resident salary — the worked companion to module five, with real line items.
- Refinancing during residency — mostly a warning label at this stage: refinancing federal loans into private ones forfeits PSLF eligibility permanently, and the article shows exactly who should still consider it.
The capstone: read your loan file cold
One assignment closes this stage. Log in to studentaid.gov and open your full loan file. For every loan: the current balance, the interest rate, whether it is subsidized or unsubsidized, and who services it. Then compute your total balance and weighted average rate. You should be able to state your total federal balance, your weighted average rate, and your loan types from memory — cold, without logging in. Every repayment decision you make for the next decade starts from those three facts.
Quick takeaway
The capstone is thirty minutes and costs nothing. A student who knows their loan file cold makes the PSLF decision, the refinancing decision, and the intern budget from data; a student who does not makes all three from anxiety.
Common questions
Should I pay interest on my loans during school?
Usually no, and the reason is mechanical. If you are likely headed toward PSLF — and most residency employers qualify — every dollar of interest paid during school is a dollar the forgiveness would have erased anyway. If you are likely not PSLF-bound, paying interest on your highest-rate loan is reasonable only after you hold enough parked cash to survive the -season cliff. Cash first, then interest.
Does my credit score matter when I owe $240,000?
Yes, and more than the loan balance does. Federal student loans in good standing barely move a score; card behavior moves it constantly. The score decides your residency apartment, your security deposits, and eventually the rate on a physician mortgage — a 0.5 percentage point rate difference on a $400,000 mortgage is roughly $2,000 per year.
Do the new federal caps affect loans I already have?
No. The $50,000 annual and $200,000 aggregate caps apply to loans first disbursed on or after July 1, 2026. Existing balances keep their original terms. The caps matter prospectively: if your remaining cost of attendance exceeds remaining federal capacity, the federal-versus-private deep cut above is your next read.
Can I start earning PSLF credit as a student?
No — qualifying payments only begin once you are in repayment and employed full time by a qualifying employer. What you can do as a student is position the start: choose the repayment plan deliberately at graduation so your first residency payment is also your first qualifying payment.
What to do next
- Log in to studentaid.gov and read your complete loan file: every balance, rate, type, and servicer. Free, thirty minutes.
- Pull your free, federally authorized credit report and confirm every account on it is yours.
- Move idle disbursement cash to an account paying a market rate.
- Compute your net worth once, loans included, and date it.
- In M4: draft your intern-year budget before you sign a lease, using Budgeting a Resident Salary.
- Before your first payment is due: read The PSLF Decision and choose your repayment plan on purpose.
Medical school is the stage with the least money and the most time, which makes it the stage where reading order matters most. The six modules above work with or without us — they simply put the sequence in one place, in the order the decisions actually arrive. This is education, not individualized financial advice.
