Student Loan Payoff: Order of Attack for a Mixed Pile of Loans

Most graduates hold several loans at different rates, some federal and some private — and the right strategy treats them very differently. Which protections matter, which loans to attack first, and when aggressive payoff is the wrong goal.

Student debt rarely arrives as one loan. A typical graduate holds a stack — subsidized and unsubsidized federal loans from different years at different rates, maybe a private loan on top — and the stack should not be treated as one blob, because its pieces carry very different rules.

Federal vs. private: the asymmetry that shapes everything

Federal loans carry protections private loans lack: income-driven repayment plans that cap payments as a share of discretionary income, deferment and forbearance options with defined rules, forgiveness programs for public service, and discharge provisions. Private loans are ordinary bank debt — whatever the promissory note says. This asymmetry drives the core strategy: extra payments go to private loans first at equal rates, because prepaying a federal loan surrenders optionality that prepaying a private loan does not.

The order of attack

Stay current on everything — federal default has uniquely unpleasant remedies, including offset of tax refunds.
Capture any employer benefits — 401(k) match first (it outranks all of this), and a growing number of employers offer direct student loan repayment assistance.
Attack high-rate private loans — avalanche order within the private pile.
Then decide about the federal pile — and here "attack" is not automatic.

When aggressive payoff is the wrong goal

A borrower on an income-driven plan heading toward Public Service Loan Forgiveness should generally pay the minimum — every extra dollar reduces the balance that would have been forgiven. Even outside forgiveness, low-rate federal loans (some vintages sit at 3–5%) compete poorly for your spare dollars against a 401(k) match, an emergency fund, or high-rate consumer debt. Refinancing federal loans into a private loan can cut the rate — and permanently destroys the protections above; it suits stable, high-income borrowers who would never use them, and burns everyone else in a bad year.

The loan calculator shows each loan's payoff timeline and interest at any payment level, the avalanche calculator orders a mixed pile by cost, and the comparison tool prices a refinance offer against what it would replace — including the honest value of what would be given up.
