Student Loan Repayment Calculator

Calculate payments, payoff timeline, and compare repayment strategies

What is a Student Loan Calculator?

A student loan calculator helps you estimate monthly payments and total repayment costs for education loans. It can compare different repayment plans, show the impact of extra payments, and help you plan your debt payoff strategy.

Formula:

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Standard formula for loan payments. Federal loans offer income-driven repayment plans with different calculations.

Frequently Asked Questions

What is the average student loan interest rate?

Federal student loan rates vary by year and loan type. As of 2024, undergraduate Direct Loans are around 5.50%, graduate loans around 7.05%, and Parent PLUS loans around 8.05%. Private loan rates vary widely based on credit.

Should I pay extra on my student loans?

If your loans have high interest rates (above 5-6%) and you have an emergency fund, extra payments can save significant money. However, prioritize employer 401k matches and high-interest debt first.

What is income-driven repayment?

Income-driven repayment (IDR) plans cap payments at 10-20% of discretionary income. After 20-25 years of payments, remaining balances may be forgiven. Good for high debt-to-income ratios but may cost more long-term.

How does student loan refinancing work?

Refinancing replaces existing loans with a new private loan, potentially at a lower rate. This can save money but forfeits federal protections like IDR plans and Public Service Loan Forgiveness eligibility.

What is Public Service Loan Forgiveness (PSLF)?

PSLF forgives remaining federal loan balances after 120 qualifying payments while working for government or non-profit employers. You must be on an income-driven plan and have Direct Loans to qualify.
