Formula

M = P × r(1+r)^n / ((1+r)^n − 1), where P is the balance, r is the monthly rate, and n is the number of months.

Worked Example

A $35,000 loan at 5.5% over 10 years (120 months): monthly ≈ $379.82, total interest ≈ $10,578.06.

Frequently Asked Questions

What is the standard repayment plan for federal student loans?

The Standard Repayment Plan spreads your payment evenly over 10 years, which usually results in the lowest total interest cost. Income-driven plans lower your monthly payment but extend the term and increase total interest paid.

How is a student loan monthly payment calculated?

The standard amortization formula M = P × r(1+r)^n / ((1+r)^n − 1) is used, where P is the balance, r is the monthly interest rate, and n is the number of months. Your payment depends on the balance, interest rate, and repayment term.

Should I refinance or consolidate my student loans?

Consolidation combines federal loans into a single Direct Consolidation Loan (keeping federal benefits). Refinancing with a private lender can lower your rate, but you lose federal protections like income-driven repayment and loan forgiveness.

Does paying extra on a student loan help?

Yes. Extra payments reduce the principal balance directly, which shortens the term and lowers total interest. Check that your extra payments are applied to principal rather than future payments.

Frequently Asked Questions

What is the standard repayment plan for federal student loans?

How is a student loan monthly payment calculated?

Should I refinance or consolidate my student loans?

Does paying extra on a student loan help?

Yes. Extra payments reduce the principal balance directly, which shortens the term and lowers total interest. Check that your extra payments are applied to principal rather than future payments.
