How it works›
Monthly payment. Standard amortization formula — loan amount, rate, and term yield a fixed payment covering principal and interest.
Amortization. Early payments lean toward interest; as the balance drops, more goes to principal.
Extra payments. Applied directly to principal, shrinking the balance and the total interest paid over the life of the loan.
