Start with principal and interest
For a fixed-rate, fully amortizing loan, the regular principal-and-interest payment is determined by the amount borrowed, periodic interest rate, and number of payments. Early payments contain more interest because the unpaid balance is larger. As the balance falls, more of the same payment goes toward principal.
For a $320,000 loan at 6.5% annual interest over 30 years with monthly payments, principal and interest are about $2,022.62 per month. That example excludes taxes, insurance, association dues, and other costs.
Build the full ownership budget
Property taxes and insurance may be collected with your mortgage payment through escrow, but they are separate costs. Mortgage insurance, homeowners association dues, maintenance, and utilities can also change the amount you need to budget.
A displayed monthly ownership cost is an estimate using the entries shown. Taxes and insurance can increase, and an estimate does not confirm what a lender will collect.
Understand extra payments
An extra principal payment can reduce the balance sooner and therefore reduce later interest, assuming it is applied to principal and there is no offsetting fee or restriction. It does not automatically reduce the scheduled payment unless the loan is recast or otherwise modified.
Compare total interest and payoff time as well as the next month’s payment. Confirm your lender’s handling of extra payments and any prepayment conditions.
