Student Loan Repayment: Standard vs. Income-Driven
How a standard fixed student loan payment is calculated, how the term affects total interest, and how income-driven plans differ.
Standard repayment
The standard plan uses fixed monthly payments over a set term (often 10 years). The payment depends on the balance, interest rate and term.
Term and total interest
Extending the term lowers the monthly payment but increases the total interest paid. Paying extra toward principal shortens the payoff and cuts interest.
Income-driven plans
Income-driven repayment (IDR) plans cap payments at a share of discretionary income and can extend the term, which may lower payments but raise lifetime interest. Federal and private loans differ.
FAQ
Should I pay extra?
Extra payments go to principal (once fees/interest are covered), reducing both payoff time and total interest.
Are the estimates exact?
This shows a standard fixed-payment estimate. IDR, subsidies and forgiveness programs change the actual numbers.
