About This Calculator
The Student Loan Calculator helps you understand your student loan repayment options and calculate monthly payments, total interest, and payoff timelines. Whether you have federal or private student loans, this calculator provides accurate payment estimates.
This calculator supports different repayment plans including standard, extended, and income-driven repayment options. Use it to compare repayment strategies and understand the total cost of your student loans over time.
Formula & Calculation Method
Student Loan Payment Formula:
Standard Plan:
Monthly Payment = [P × R × (1+R)^N] / [(1+R)^N - 1]
Where:
P = Loan amount (principal)
R = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
N = Loan term in months (Years × 12)
Total Interest = (Monthly Payment × N) - P
Federal student loans typically offer fixed interest rates and various repayment plan options. Income-driven repayment plans cap payments based on discretionary income, which can extend the repayment period but reduce monthly payments.

Frequently Asked Questions
What is the difference between federal and private student loans?
Federal student loans typically offer fixed rates, income-driven repayment plans, and forgiveness options. Private loans may have variable rates and fewer repayment options. Federal loan rates are set by Congress, while private rates vary by lender and credit score.
What are income-driven repayment plans?
Income-driven repayment plans cap your monthly payment at a percentage of your discretionary income (usually 10-20%). Payments are recalculated annually based on income and family size. After 20-25 years, remaining balance may be forgiven.
Can I pay off my student loans early?
Yes! Most student loans have no prepayment penalty. Making extra payments reduces your total interest paid and payoff time. Apply extra payments to principal to maximize savings.
What is a typical student loan interest rate?
Federal student loan rates are set annually and vary by loan type (2023 rates range from 4.99% to 7.54%). Private loan rates vary widely based on credit score, typically ranging from 3% to 13% or more.
