The Student Loan Repayment Planner is a dynamic tool designed to model how different payment strategies impact your student loans. It calculates estimated monthly payments, total interest paid, and the overall repayment period based on your loan details and chosen parameters, revealing the long-term implications of your choices.
This calculator is ideal for anyone with student loans—if you are just starting repayment, looking to refinance, or considering changing your payment plan. Recent graduates can use it to choose an initial strategy, while established borrowers can explore options to pay off debt faster or manage payments more effectively. It's also valuable for those comparing federal income-driven plans versus standard or aggressive private refinance options.
Interpreting Results
Start with Accelerated payoff timeline. Then compare Baseline payoff and Months saved before deciding what changes the answer most.
Input Steps
Field by field
- 1
Principal
Enter principal, APR, required monthly payment, extra payment, and any autopay discount using the servicer's current numbers. If the loan is federal, decide first whether forgiveness, IDR, or deferment protections matter more than fastest payoff.
- 2
APR Percent
Read baseline payoff, accelerated payoff timeline, and months saved. An autopay discount of 0.25% is small but permanent, so include it only if you actually use autopay.
- 3
Monthly Payment
Aggressive payoff is usually stronger for private loans or high-rate federal loans after protections are weighed. If an extra payment only shaves a few months, the cash may belong on higher-rate debt or emergency reserves instead.
- 4
Extra Payment
Choose if you are optimizing for interest savings, payment flexibility, or forgiveness eligibility, then automate extra payments only if they support that goal. Use the loan payoff calculator for one-loan sensitivity checks.
- 5
Autopay Discount Percent
Re-run after recertification, rate changes, policy changes, or any jump in income. Track required payment, extra payment, and payoff date under the strategy you chose.
Run one base case and one sensitivity case before trusting a single output.
