Frequently Asked Questions

How is the monthly loan payment calculated?

Monthly payment = P ร— (r(1+r)^n) / ((1+r)^n - 1), where P is the principal, r is the monthly interest rate, and n is the number of payments. This is the standard amortization formula used by banks.

What is an amortization schedule?

An amortization schedule is a table showing each payment over the loan term, broken down into principal and interest portions. Early payments are mostly interest; later payments are mostly principal.
