Student Loan Payoff Calculator
This student loan payoff calculator estimates how much faster you can pay off a student loan by sending extra monthly payments or a one-time lump-sum payment.
It compares your current plan with an accelerated payoff plan.
Use it to see time saved, interest saved, and the new payoff timeline.
That makes it useful for budgeting after graduation or during refinancing decisions.

Assumptions
- The comparison uses fixed monthly interest and fixed payment behavior.
- If your payment is too low to cover monthly interest, the payoff plan becomes unrealistic.
- Actual servicer payment processing and interest accrual can differ slightly from this estimate.
How this calculator works
Formula used
The calculator simulates monthly loan interest and payment reductions under your current payment, then compares that with a faster plan that includes extra payments.
Example calculation
If your current payment is $350 and you add another $75 each month, the calculator compares your original payoff schedule with the faster plan and estimates interest saved.
