About Student Loan Calculator
A student loan balance, interest rate and repayment term are enough for this calculator to produce the standard monthly payment, total interest, payoff date, and a comparison of the standard 10-year plan with 15, 20 and 25-year extended terms. An extra-payment field re-amortizes the loan month by month to show interest saved and time cut, while an income-driven panel estimates IBR (15% of discretionary income) and PAYE (10%) payments from income, family size and the federal poverty guideline. Nothing is sent to a server.
Use Cases
How to use
Type your total balance into Loan Balance ($) and your rate into Interest Rate (%).
Pick a repayment length in Loan Term: 10 Years (Standard), 15, 20 or 25 Years.
Add any monthly overpayment in Extra Payment ($) to model paying the loan off faster.
Read the Monthly Payment and Payoff Date cards, then compare the Standard Repayment panel against With Extra Payments to see interest and time saved.
Scroll to Based on income, enter your Annual Income and choose a Family Size to get estimated IBR Payment and PAYE Payment figures.
Use the Repayment Options table to compare 10, 15, 20 and 25 year plans; the lowest total interest is highlighted in green.
