What is a student loan payoff calculator?

This calculator estimates student loan payoff timing from your current balance, APR, and monthly payment amount.

Use it to understand payoff horizon and interest tradeoffs when increasing monthly payments.

Monthly amortization simulation using loan balance, APR, and fixed payment

You can test extra-payment scenarios by increasing monthly payment and comparing results.

Student loan balance is $28,000 at 5.5% APR with a $350 monthly payment.

The calculator estimates months to payoff and total interest under this payment pace.

Even small extra principal payments can reduce total interest over long terms.

Estimated months to payoff — Projected months to clear this loan at your current payment level.
Estimated total interest — Modeled interest cost from now to payoff.
Estimated total paid — Principal plus interest total over the payoff timeline.

Check servicer rules for how extra payments are applied to principal.

This version models one loan. Combine balances only if APRs are similar.

No. It models direct amortization from payment and APR only.

Compare rates, terms, and protections before refinancing federal loans.
