Key takeaways

  • Sample only: $30,000 · 5.5% · 10 years → payment about $325.58, interest about $9,069.46.
  • Longer terms usually lower the monthly payment and raise total interest for the same rate and balance.
  • Not a federal plan: Income-driven repayment, deferment, and forgiveness are out of scope. This is transparent amortizing math for learning.
  • How the student loan calculator works

How it works

Standard fixed-rate amortization: a level payment covers interest then principal so the balance reaches zero by the end of the term under constant assumptions. Details: how we calculate.
