Compare the estimated lifetime cost of a private refinance offer with a federal income-driven repayment plan—including possible forgiveness and taxes.
Refinancing means a new private loan pays off your current loans, ideally at a lower rate. Income-driven repayment (IDR) is a federal plan with payments tied to income; a remaining balance may be forgiven after 20 or 25 years and is generally treated as taxable income under this calculator’s assumption.

Method
The refinance estimate uses the standard fixed-payment amortization formula. The IDR estimate simulates the balance month by month at the current interest rate, subtracting the entered payment without adding special interest-capitalization events. Estimated forgiveness tax equals the remaining balance multiplied by the tax rate you entered. This is a simplified model.
What is excluded
Interest capitalization events and changing IDR rules
Changing income and yearly IDR payment adjustments
State taxes on forgiveness
Refinance fees or origination costs
Variable-rate behavior
Public Service Loan Forgiveness (PSLF) and other federal forgiveness programs
