What is in a mortgage payment

Four letters: PITI

Principal repays the loan, interest pays for borrowing, and many lenders collect property tax and homeowners insurance monthly through an escrow account. HOA or condo dues arrive separately but weigh on the same budget.

Early payments are mostly interest

A fixed payment is calculated so the loan reaches zero exactly at the end of the term. In early years most of each payment is interest; the principal share grows over time.

What an estimate leaves out

Mortgage insurance on low-down-payment loans, points, closing costs, rate changes on adjustable loans, and escrow shortfalls all move the real number. Tax and insurance are annual figures you supply, not looked-up local rates.

Boundary: the calculator is an educational scenario, not a quote, a preapproval, or advice. Lenders must give you a standardized Loan Estimate with the real numbers.

A worked monthly payment

Principal and interest come from a formula. Property tax, insurance, and dues are added on top as monthly shares of annual or monthly bills.

A $300,000 loan at 6.5% for 30 years has a principal-and-interest payment of about $1,896.20. Add an illustrative property tax of $3,600 a year ($300 a month), homeowners insurance of $1,500 a year ($125 a month), and HOA dues of $50 a month, and the amount to budget is about $2,371.20.

In the first month the interest is $300,000 × 0.065 ÷ 12 = $1,625, so only about $271 of the $1,896 reduces the balance. That share grows every month until, near the end of the term, almost the whole payment is principal.

Reading the Loan Estimate

Lenders provide a standardized three-page Loan Estimate, and the Consumer Financial Protection Bureau publishes an explainer for reading it item by item.

The first page shows the monthly principal and interest, whether mortgage insurance is added, and an Estimated Total Monthly Payment. It also lists estimated taxes, insurance, and assessments and marks which are paid through escrow. Anything not escrowed still has to be paid — just not to the lender — so it belongs in the budget even though it is missing from the lender’s payment.

The CFPB recommends asking more than one lender for a Loan Estimate and comparing them, including the origination charges and the Comparisons section on the last page.
