How the payment is calculated

Principal and interest use the standard fixed-rate amortization formula: payment = L × r ÷ (1 − (1 + r)⁻ⁿ), where L is the loan amount, r is the monthly rate (annual rate ÷ 12) and n is the number of monthly payments. Early payments are mostly interest; later ones are mostly principal. The CFPB explains amortization in more detail.

Property tax, insurance and HOA dues are added on top. Many lenders collect tax and insurance monthly through an escrow account, so your payment to the servicer usually includes them.

Assumptions in this calculator

Fixed rate for the whole term. Adjustable-rate loans can change after the intro period.
The example rate (6.25%) is for illustration only. Check the Freddie Mac PMMS for the latest weekly average, then get Loan Estimates from several lenders.
PMI is shown only for down payments under 20% and stops once the scheduled balance reaches 80% of the price. Under federal law you can ask to cancel PMI at 80% and it generally ends automatically at 78% (CFPB). FHA and VA loans work differently.
Tax, insurance and HOA are held flat. In real life they usually rise over time.
Extra principal is applied every month starting with the first payment.

Frequently asked questions

What is included in a mortgage payment?

Usually principal, interest, property tax and homeowners insurance (often called PITI), plus mortgage insurance if you put less than 20% down on a conventional loan, and HOA dues if the home has them.

When does PMI go away?

On most conventional loans for a primary home you can ask to cancel PMI when your balance is scheduled to reach 80% of the original value, and it generally ends automatically at 78%, according to the CFPB.

Is the interest rate in this calculator a real quote?

No. It is an example. Rates change every week and depend on your credit, down payment and loan type. Compare Loan Estimates from several lenders.

How do extra payments change my loan?

Extra money applied to principal lowers the balance faster, so you pay less total interest and finish sooner. Check that your loan has no prepayment penalty.
