How to use this mortgage calculator
Enter the home price, down payment, interest rate, and term. Add yearly property tax, yearly homeowners insurance, an estimated PMI rate, and monthly HOA dues when they apply. The calculator updates the estimated monthly payment in your browser.
What is included in the monthly mortgage payment
The main payment includes principal and interest. Many homeowners also budget for property tax, homeowners insurance, private mortgage insurance, and HOA dues. These added costs can materially change the monthly amount, especially in areas with high property taxes, expensive insurance, or community fees.

How PMI is estimated
Private mortgage insurance is commonly required when the down payment is below 20%. This calculator estimates PMI as a yearly percentage of the loan amount and divides it into monthly payments.
Why mortgage estimates can differ from lender quotes
Actual lender numbers can include points, credits, origination fees, escrow setup, prepaid interest, county fees, and rate-lock terms. Use this page for planning, then compare official loan estimates before making a decision.
When comparing two offers, look at the loan estimate, cash to close, APR, interest rate, points, lender credits, and whether taxes and insurance are escrowed. A lower principal-and-interest payment is not always the lower total housing cost.
Common mortgage planning mistakes
The biggest mistake is comparing only principal and interest while ignoring the full housing payment. Taxes, insurance, PMI, HOA dues, utilities, repairs, and move-in costs can change affordability quickly. It is also easy to compare two rates without noticing that one quote includes discount points or a larger upfront cost.
How to interpret the result
Treat the monthly payment as a planning number, not a loan approval. If the result feels close to your comfort limit, test a higher insurance cost, a higher tax estimate, and a slightly higher interest rate. A home that only works under perfect assumptions may feel much tighter once escrow changes, repairs, and normal life expenses arrive.
Mortgage payment FAQ
Does this include closing costs? No. Closing costs are separate from the ongoing monthly payment and vary by lender, location, and loan type.
Can I use this for a refinance? Yes, for a rough monthly-payment estimate. Enter the new loan amount as the price and use zero down payment.
