How it works
The calculator uses the loan amount, annual interest rate, and repayment term to estimate a fixed monthly payment. The repayment term is converted to months by multiplying the years by 12 and rounding to the nearest whole month.
For loans with interest, it applies the standard amortization formula using the monthly interest rate, which is the annual rate divided by 12. The monthly payment is the amount that would fully repay the principal and interest over the selected number of months.
If the interest rate is 0%, the payment is simply the loan amount divided by the number of monthly payments. Total repaid equals the monthly payment multiplied by the number of payments, and total interest equals total repaid minus the original loan amount.
This calculator assumes a fixed interest rate, monthly fully amortizing payments, no fees, no deferment or forbearance, and no extra payments. Results are educational estimates and not financial advice.
Example calculation
For a $30,000 student loan at 5.50% interest over 10 years, the term is 120 monthly payments. Using the fixed-rate amortization formula, the estimated monthly payment is about $325.58. Over the full term, the borrower would repay about $39,069.83 total, including about $9,069.83 in interest.
Frequently asked questions
What is a fixed monthly student loan payment?
It is a payment amount that stays the same each month and is calculated to pay off the loan balance plus interest by the end of the repayment term.
Does a longer repayment term lower my payment?
Yes, spreading the loan over more months usually lowers the monthly payment, but it typically increases the total interest paid.
What happens if the interest rate is 0%?
The calculator divides the loan amount evenly by the number of monthly payments, so there is no interest added.
Does this include extra payments or loan forgiveness?
No. It assumes regular monthly payments only and does not account for extra payments, forgiveness, deferment, forbearance, or fees.
Can I use APR as the annual interest rate?
Yes, for a simple estimate you can enter the loan’s APR or fixed annual rate, though actual lender calculations may vary.
