How to Use the Student Loan Payoff Calculator
Enter your total student loan balance and the average interest rate across all your loans. If you have multiple federal loans with different rates, use the weighted average. Set the standard term to match your repayment plan - the standard federal repayment term is 10 years.
Add an extra monthly payment amount you can realistically afford. Even $25 or $50 extra per month can save hundreds in interest. Choose a repayment strategy: Standard applies extra to principal; Avalanche targets the highest-rate loan first; Snowball focuses on the smallest balance first for psychological wins.
Click "Calculate" to compare standard repayment against your accelerated plan. You will see the monthly payment difference, total interest savings, and how much sooner you can become debt-free.
Pro tip: The avalanche strategy saves the most money mathematically, but the snowball strategy has a higher success rate for many borrowers because of the motivation from early wins.
Student Loan Payoff Formula
The standard monthly payment is calculated using the amortization formula:
Where M is the monthly payment, P is the loan principal, r is the monthly interest rate (annual rate / 12), and n is the total number of monthly payments.
With extra payments, the additional amount is applied directly to the principal each month, reducing the total interest and shortening the payoff period.
