How the Repayment Calculator works
The calculation follows the standard method used across the US — no shortcuts, no hidden assumptions. Here is exactly what happens behind the scenes:
Frequently Asked Questions
Is extended repayment worth it?
Extended cuts payments ~30–40% but can double lifetime interest. Useful for cash-flow crunches; painful as a default strategy.
What about income-driven plans?
IDR sets payments from discretionary income with forgiveness after 20–25 years — valuable for low income relative to debt, though forgiven amounts may be taxable.
