Monthly Payment

Fixed monthly instalment based on your loan details
This calculator estimates your monthly student loan payment and payoff timeline. Actual terms may vary by loan type and lender. Always verify with your loan servicer before making decisions.
A student loan calculator estimates your monthly student loan payment using the standard EMI (Equated Monthly Instalment) formula based on your total loan balance, annual interest rate, and desired repayment term in years. It calculates total interest paid, total amount repaid, and shows how optional extra monthly payments reduce your payoff time and interest cost.
The calculator applies your interest rate and repayment term to compute your fixed monthly payment using the reducing-balance amortization method. If you add extra monthly payments, it simulates month-by-month payoff to show exactly how many months you'll need to clear the debt, helping you visualize the real impact of accelerated repayment.
EMI = [P × r × (1 + r)^n] / [(1 + r)^n - 1]; where P is loan balance, r is monthly interest rate (annual rate ÷ 1200), n is repayment term in monthsThe EMI formula calculates a fixed monthly instalment that covers both principal and interest. With extra payments, the calculator iterates month-by-month, applying each extra amount to principal, which reduces the remaining balance faster and decreases total interest paid.
| Input | Result | Notes |
|---|---|---|
| Balance: $30,000 | Rate: 5.5% | Term: 10 years | Extra: $0 | Monthly Payment: $317 | Total Interest: $8,060 | Total Paid: $38,060 | Payoff: 10 years | A typical federal student loan with standard 10-year repayment plan |
| Balance: $50,000 | Rate: 6.5% | Term: 15 years | Extra: $100 | Monthly Payment: $405 | Total Interest: $22,810 | Extra saves ~3 years and $8,000 in interest | Extended term keeps monthly payment manageable; extra payment cuts years off the loan |
| Balance: $25,000 | Rate: 4.5% | Term: 5 years | Extra: $0 | Monthly Payment: $460 | Total Interest: $2,620 | Total Paid: $27,620 | Payoff: 5 years | Aggressive 5-year repayment plan minimises total interest paid on smaller loan |
Federal student loans are issued by the government, typically have lower fixed interest rates (4–8%), and offer flexible repayment plans and forgiveness options. Private loans come from banks or lenders, rates vary (usually 5–12%), and have fewer consumer protections. This calculator works for both.
Total interest depends on your loan balance, interest rate, and repayment term. A $30,000 loan at 5.5% over 10 years costs ~$8,060 in interest. Stretching it to 20 years increases interest to ~$18,000. Use this calculator to see exact numbers.
Either works—extra monthly payments are easier to budget for and build the repayment habit. Lump-sum payments (like tax refunds) directly reduce principal. Most federal loans have no prepayment penalty, so choose what fits your cash flow best.
Yes, especially with federal loans. You can switch between Standard, Graduated, Extended, and Income-Driven Repayment plans. Private loans are less flexible. Use this calculator to model different plans before switching.
Missing payments harms your credit score and may result in late fees. If you struggle, contact your loan servicer immediately—federal loans offer deferment or forbearance. Do not ignore loan bills; this calculator helps you budget to avoid missed payments.
Extra payments go directly to principal, reducing your remaining balance faster. Fewer principal dollars earn interest over time, so you pay less total interest and finish the loan sooner. Even $50 extra per month can save years.
