Forgiveness changes this math
Loans headed toward Public Service Loan Forgiveness or income-driven forgiveness usually shouldn't be prepaid — extras mostly shrink what would be forgiven. Run this plan on the loans you intend to pay off.What this may mean for you
Highest-rate-first is never slower in total than any other fixed order. If a quick early win would keep you motivated, clearing the smallest loan first costs a little more and pays back in momentum — the Snowball vs. Avalanche comparison shows the exact difference for your list.

Understanding this calculator
Most graduates hold a stack of loans at different rates — servicer-grouped, confusing, and easy to treat as one blob. Payoff order matters: aiming extras at the highest rate first (and rolling each finished loan's payment into the next) can shave meaningful interest versus spreading extras evenly.
The planner treats your list the way the debt-avalanche method would, and reports the schedule loan by loan — which also gives you the satisfying part: dates. Each loan gets a month it dies.
Assumptions and methodology
- Monthly simulation: minimums on every loan, extras to the highest-rate loan, freed payments rolling forward (avalanche).
- Each loan's payoff month and the overall debt-free date are reported; fixed rates and no new borrowing assumed.
- Income-driven plans and forgiveness tracks are not modeled — prepayment may not benefit loans headed for forgiveness.

Common questions
Should subsidized loans be treated differently?
In repayment they behave like any fixed-rate loan, so rate order still applies. The subsidy matters mainly during deferment periods, which this planner doesn't model.
