What Is a Student Loan Calculator?

This calculator estimates student-loan payments, payoff timing, and interest using the balance, rate, term, and extra-payment assumptions you enter.

Who Should Use This Tool?

Borrowers comparing repayment terms, evaluating extra payments, or preparing questions for a federal or private loan servicer can use this as a starting point.

Examples

Standard Repayment

Example Input

$35,000 balance at 5.5% APR over 10 years.

Sample Output

Estimates the monthly payment, total scheduled repayment, and interest under the selected term.

Extra Principal

Example Input

$35,000 balance at 5.5% APR with an extra $100 per month.

Sample Output

Shows the projected reduction in payoff time and estimated interest compared with the base payment.

Common Use Cases

Compare standard payments with an extra-principal plan, then review repayment-program details with your servicer. Our debt payoff calculator can help place the loan in a wider debt plan.

How to Get a Better Estimate

Use the current principal, interest rate, and repayment status from your statement. Federal programs, income-driven plans, capitalization, and forgiveness rules require separate official verification.

Common Mistakes

Do not assume that making an extra payment always reduces the next bill or changes the due date. Confirm how your servicer applies extra payments and whether prepayment rules apply.

FAQ

Does this calculate income-driven repayment?

It provides an estimate from the inputs supported by the page. Verify eligibility, payment formulas, and current federal program rules with your servicer or StudentAid.gov.

How do extra payments affect a student loan?

When applied to principal, extra payments may reduce the projected payoff time and interest. Confirm the application method with your servicer.

Can student loans be forgiven?

Some borrowers may qualify for specific programs, but eligibility and rules change. Check current official government guidance before relying on forgiveness in a plan.

Why is my student loan payment different from my servicer's amount?

Servicer payments depend on the exact loan balance, interest rate, repayment plan, capitalization events, payment date, and any income-based or forgiveness rules. Use the calculator for scenario planning and compare its inputs with your current statement.

Why Use This Calculator?

Run private repayment scenarios in your browser and use the outputs to prepare a more informed conversation with your loan servicer.
