A fixed student loan payment is usually a level monthly installment that covers interest first, then principal, so the balance reaches zero by the end of the term if the rate and payments stay as modeled.
Core idea
Use balance, annual rate as a monthly rate, and term in months in the standard amortization formula. Optional extra payments reduce principal faster.
