Frequently asked questions
- Why is total paid slightly higher than my real payoff?
- We report payment × months, but the final month's payment is usually partial. The true total is a few dollars lower; this convention keeps the interest figure conservative and easy to check.
- What if my payment doesn't cover the interest?
- If your monthly payment is at or below the monthly interest, the balance never falls and the loan never amortizes. The calculator flags this instead of returning a payoff time.
- Does this include loan forgiveness or income-driven plans?
- No. It models a fixed payment on a standard amortizing loan. Income-driven repayment, forgiveness, and interest capitalization can change the real outcome — check studentaid.gov.
