Calculate the monthly EMI and total interest for an education loan, with an optional moratorium (grace) period.
This tool calculates your monthly student loan payment, total interest paid, and full repayment timeline based on the loan balance, interest rate, and repayment term. It helps students and graduates understand and plan for loan repayment.
Monthly Payment = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of monthly payments over the repayment term.
Enter your student loan balance, interest rate, and repayment term, and the calculator returns your estimated monthly payment and total repayment cost.
Example: A $30,000 student loan at 5.5% interest over 10 years results in a monthly payment of approximately $326, with total interest paid of roughly $9,120 over the repayment period.
A longer repayment term (like extended or income-driven plans) lowers monthly payments but increases total interest paid over the life of the loan, while a shorter term increases monthly payments but reduces total interest cost.
With subsidized loans, the government typically covers interest while the borrower is in school (for eligible loans), while unsubsidized loans accrue interest from disbursement regardless of enrollment status — this can meaningfully affect the total balance owed at graduation.
Yes, extra payments (specified as going toward principal) reduce the balance faster, decreasing total interest paid and potentially shortening the repayment timeline, though it's worth understanding your specific loan servicer's payment allocation policy.
Income-driven plans typically set payments as a percentage of discretionary income rather than a fixed amortization schedule, which can lower monthly payments but often extends the total repayment period and total interest paid compared to standard repayment.
Refinancing can lower interest costs if you qualify for a meaningfully better rate, but it's worth carefully considering any trade-offs, such as losing federal loan benefits (like certain forgiveness programs) when refinancing federal loans into private ones.
This calculator estimates your monthly student loan payment based on your total loan balance, interest rate, and repayment term, using the same amortization principles that apply to other types of installment loans — each payment covers both interest and a portion of principal, with the exact split shifting over time as your balance decreases. Because student loans often carry different interest rates depending on whether they're federal or private, subsidized or unsubsidized, even loans of the same total amount can require quite different monthly payments.
Extending your student loan repayment term lowers your monthly payment, which can provide welcome short-term budget relief, but it also significantly increases the total interest you'll pay over the life of the loan. Conversely, choosing a shorter repayment term or making extra payments toward principal when you're able to can meaningfully reduce total interest paid, even though it means a higher monthly commitment in the near term.
Keep in mind that many student loan borrowers, particularly those with federal loans, have access to income-driven repayment plans, deferment, forbearance, or loan forgiveness programs that can significantly change what you actually pay compared to a standard fixed-payment calculation. This calculator is most useful for understanding the baseline standard repayment scenario, but for a full picture of your specific repayment options, it's worth reviewing your loan servicer's official tools and speaking directly with them.
Refinancing a student loan to a lower interest rate can reduce your monthly payment or total interest paid, but it's worth carefully weighing the trade-offs first, since refinancing federal loans into a private loan typically means giving up access to income-driven repayment plans and forgiveness programs that only apply to federal loans. Running your current loan terms against a potential refinance offer through a calculator like this one can help clarify whether the numbers genuinely favor switching.
If you're managing several student loans with different balances, interest rates, and terms, running each one individually through this calculator lets you see exactly how much each loan is costing you in interest, which is useful for deciding which loan to prioritize paying off first. Many borrowers choose to focus extra payments on the loan with the highest interest rate first, since that's typically where the most total interest can be saved, while making minimum payments on the rest.
Once you know your estimated monthly payment, building it directly into your monthly budget as a fixed expense — the same way you'd treat rent or a utility bill — helps ensure it gets paid consistently and doesn't get squeezed out by other discretionary spending.
What is income-driven repayment, and how does it change monthly student loan payments? Income-driven repayment plans calculate monthly payments as a percentage of discretionary income rather than a fixed amortization schedule, which can significantly lower payments for borrowers with lower income relative to their loan balance, though often extending the total repayment period.
How does loan forgiveness affect total repayment cost calculations? Certain student loan programs offer forgiveness of remaining balance after a set number of qualifying payments, which can substantially reduce total repayment cost for eligible borrowers compared with a standard full-balance amortization calculation.
