How the mortgage calculation works
Your principal and interest payment comes from the standard amortized-loan formula: the loan amount, the monthly rate, and the number of payments determine a fixed payment that pays the loan off exactly at the end of the term.
Early payments are mostly interest; later payments are mostly principal. The balance chart above shows how slowly the balance falls at first, then accelerates.
Lowering your payment
Three levers move your payment: a larger down payment (less to borrow), a lower rate (shop lenders and consider points), or a longer term (lower payment but more total interest). Use the related calculators to test refinancing or making extra payments.
