How to Use Student Loan Calculator

Our Student Loan Calculator is a free financial utility: 1. Input your current student loan principal amount. 2. Enter the Annual Interest Rate (APR) and selected term (in months). 3. Input any extra monthly payments to see instant payoff adjustments. 4. Review the monthly or annual amortization schedule below.

Student Loan Calculator Formula / How It Works

This calculator uses standard loan formulas to compute fixed monthly payments. It runs an iterative month-by-month ledger simulation to apply additional principal payments, recalculating interest reduction and tracking balance decreases dynamically.

Formula:Payment = P * [r(1+r)^n] / [(1+r)^n - 1]; Total Interest Saved is modeled by subtracting simulated balance tracks.

Example Calculation:

For example, financing a $30,000 student loan at 5% APR over 120 months results in a monthly payment of $318.20 and a total interest cost of $8,183.59.
