Plan Your Student Loan Repayment Strategy

Student loan debt can feel overwhelming, but understanding your repayment options empowers you to make smarter financial decisions. Our calculator helps you see exactly what your monthly payments will be, how much you'll pay in interest over the life of the loan, and how extra payments can save you thousands.

Understanding Student Loan Repayment

Student loans use standard amortization, where early payments go mostly toward interest while later payments primarily reduce principal. Federal loans offer various repayment plans (Standard, Graduated, Income-Driven) while private loans typically have fixed terms. Knowing your numbers helps you choose the best strategy for your situation.
