Frequently Asked Questions

What repayment plans are available for student loans?

Options often include standard, graduated and income-driven plans, each trading off monthly payment size against total interest.

What is an income-driven repayment plan?

It caps payments at a percentage of your discretionary income, lowering monthly cost but often extending the term.

Does a longer term cost more?

Yes. Stretching payments lowers each month’s bill but adds interest over the life of the loan.
