🎓 Student Loan Calculator
Estimate your monthly student loan payment, accounting for interest that may build up before repayment begins.
How student loan interest works
Many student loans (especially unsubsidized federal and private loans) begin accruing interest as soon as they’re disbursed, even while you’re still in school and during a post-graduation grace period. If that accrued interest isn’t paid, it’s typically added to (capitalized into) your principal balance once repayment starts, meaning you then pay interest on that added interest too.
How this calculator works
The calculator estimates interest that accrues during your grace period using simple monthly accrual, adds it to your original loan amount to find your starting repayment balance, and then applies the standard amortization formula over your repayment term to find your fixed monthly payment and total interest.
This is a general estimate for educational planning. Actual federal and private loan terms, interest accrual methods (often daily rather than monthly), and capitalization rules vary — check with your loan servicer for exact figures.
