What to know
Use this calculator when you want to compare home-price scenarios, understand principal-and-interest versus full monthly housing cost, or preview refinance affordability.
How to read the monthly payment
The base mortgage payment covers principal and interest. The estimated monthly housing total adds the recurring property tax, insurance, HOA, and PMI amounts you enter so you can compare the loan payment against a more realistic all-in monthly cost.
What the payoff curve shows
The payoff curve and first-year amortization rows show how early payments are split between interest and principal. That makes it easier to see how a rate or term change affects both the monthly payment and the speed at which the balance declines.
Common mistakes this page helps avoid
Many borrowers compare only principal and interest and underestimate the real monthly housing cost. Separating principal-and-interest from taxes, insurance, HOA, and PMI makes the assumptions visible instead of hiding them behind a single number.

FAQ
Common questions
Does this mortgage calculator include taxes and insurance?
It includes them only if you enter annual property tax and homeowners insurance amounts. The amortized loan payment itself is still shown separately as principal and interest.
What is the difference between monthly payment and estimated housing total?
Monthly payment is principal and interest only. Estimated housing total adds recurring property tax, homeowners insurance, HOA dues, and PMI to that base payment.
Is PMI included automatically?
No. PMI appears only if you enter a monthly PMI amount, because not every loan requires it and PMI can end earlier than the full loan term.
Is this good for adjustable-rate loans?
No. This page is meant for fixed-rate mortgages only. Adjustable-rate loans need a different model because the interest rate can change over time.
