How much will your student loan cost each month once school ends? That one number shapes your budget for years after graduation. The Education Loan Calculator gives you that monthly payment, plus the total interest and the full amount you will repay.
You enter the loan amount, the yearly interest rate, and the loan term in years. The tool uses the standard fixed-payment loan formula. It suits students, graduates, and parents comparing college loan offers or planning a repayment budget.

What the Calculator Does
The tool turns three numbers into a repayment picture. It shows results for a sample $40,000 loan as soon as the page loads.
- Monthly Payment: the fixed amount due each month until the loan is paid off.
- Total Interest: everything you pay beyond the amount you borrowed.
- Total Paid: the loan amount plus all interest, or every payment added together.
- Zero-rate support: a 0% rate splits the loan evenly across the months.
- Calculate Monthly Payment button: refreshes the results after you change any field.
How to Use It, Step by Step
- Enter what you owe, or plan to borrow, in Total Loan Amount ($).
- Enter the yearly rate from your loan offer in Annual Interest Rate (%). Type 6.5 for 6.5%.
- Enter the payoff period in Loan Term (Years). Ten years equals 120 monthly payments.
- Press Calculate Monthly Payment. The results do not update until you press it.
- Change the term or rate and press the button again to compare options.
The loan must be $1,000 to $10,000,000, and the rate 0% to 30%. The term runs from 1 to 30 years. A blank or out-of-range field shows a red message, and all three results read N/A.
The Student Loan Payment Formula
The tool uses the same amortization formula that most fixed-rate lenders use. Each payment covers that month's interest, and the rest reduces your balance.
Loan Amount (P)+Monthly Rate (r)+Months (n)=Monthly Payment
- Monthly payment = P × r × (1 + r)^n ÷ ((1 + r)^n - 1).
- P is the loan amount. r is the annual rate ÷ 100 ÷ 12. n is the years × 12.
- If the rate is 0, the payment is simply P ÷ n.
- Total paid = monthly payment × n. Total interest = total paid - P.
Worked Example: Three Repayment Terms
Jasmine finished nursing school with $32,000 in loans at an example rate of 6.5%. She runs the tool three times to compare repayment terms.
| Term | Monthly Payment | Total Interest | Total Paid |
|---|
| 10 years | $363.35 | $11,602.42 | $43,602.42 |
| 15 years | $278.75 | $18,175.78 | $50,175.78 |
| 20 years | $238.58 | $25,260.02 | $57,260.02 |
Moving from 10 to 20 years cuts her payment by $124.77 a month. But it more than doubles her interest, adding $13,657.60. A longer term buys breathing room at a real price.
How to Read the Results
Monthly Payment is the amount to plan for in your budget. Compare it with your expected take-home pay after graduation. Our take-home pay calculator can estimate that paycheck.
Total Interest is the true cost of borrowing. It grows quickly with longer terms and higher rates.
Total Paid is everything you will pay over the life of the loan. It assumes you make every payment on time and never pay extra.
Ways to Lower Your Total Cost
Paying a little extra each month goes straight to principal and shortens the loan. See how much you could save with the extra payment savings calculator.
Do you also carry card or car debt? A debt payoff planner helps you pick which balance to attack first.
Borrowing less is the strongest lever of all. Families still a few years out can plan ahead with our college savings calculator. For any other fixed-rate loan, the general loan payment calculator runs the same math.
Federal and private student loans differ on rates, fees, deferment, and repayment plans. Check your loan servicer or lender for the terms that apply to you. Browse more tools in our finance and business calculator hub.
Limitations and Assumptions
- The tool assumes a fixed rate and equal monthly payments from the first month.
- It does not model a grace period, interest that builds while you are in school, or fees.
- Income-driven, graduated, and extended plans change payments over time, so this tool cannot show them.
- Results only refresh when you press the button, so check that you pressed it after each change.
- There is no copy or reset button, so note your results before you change a field.
FAQs About the Education Loan Calculator
How is a student loan monthly payment calculated?
The tool divides the yearly rate by 12 and multiplies the years by 12. It then applies the standard amortization formula to find one fixed payment that clears the loan.
Can I enter a term like 2.5 years?
Yes, as long as the years work out to whole months. A $32,000 loan at 6.5% over 2.5 years means 30 payments of $1,158.56. A term like 2.3 years gives a message instead.
Should I pick a longer repayment term?
A longer term lowers the payment but raises total interest. In the example above, 20 years costs $13,657.60 more than 10 years. Choose the shortest term your budget can handle.
Does the calculator include interest that builds during school?
No, it starts from the balance you enter. If interest has been added to your loan, enter the current total balance instead of the original amount.
Can I combine several student loans?
You can add balances that share one rate. For loans at different rates, run each loan separately and add the monthly payments together.
What happens if I enter a 0% rate?
Zero is a valid rate, so the tool divides the loan evenly across the months. A $32,000 loan over 10 years would cost $266.67 a month, with no interest.
