payable

Mortgage and loan payment calculator: enter principal, annual rate, and term to get the exact monthly payment, total amount paid over the life of the loan, and total interest owed. Built for home-buying estimates, amortization sanity checks, and personal-finance planning agents that need real numbers instead of a rough guess. Not financial advice — just exact arithmetic on the inputs you give it.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
