How much of the monthly payment is the mortgage itself, and how much is ownership expense?
A house can be affordable on paper until property tax, homeowners insurance, or association fees enter the picture. This example puts common recurring charges beside the principal-and-interest payment instead of treating them as afterthoughts.
What we put into the calculator
With a 20% down payment on a $350,000 home, the financed principal is $280,000. A fixed 6.5% annual rate over 30 years determines principal and interest. We add an illustrative $4,200 in annual property tax and $1,800 in annual homeowners insurance. No HOA or PMI is assumed.
The numbers behind the result
| Principal and interest per month | $1,769.79 |
|---|---|
| Property taxes per month | $350.00 |
| Home insurance per month | $150.00 |
| HOA per month | $0.00 |
| Estimated PMI per month | $0.00 |
| Monthly total including extra | $2,269.79 |
| Starting loan balance | $280,000 |
What the result is really telling you
Notice how much the non-mortgage costs add each month. Changing the down payment changes the principal, but local taxes and insurance can also change the total significantly. The example deliberately leaves closing costs, repairs and utilities outside the displayed monthly payment.
Try changing one number
Open the mortgage calculator and change the interest rate to 7.5%, then increase the down payment. Try the numbers separately: you will see which has the larger effect on the monthly total.

Your lender’s Loan Estimate, property-tax record, insurance quotation and possible PMI schedule are better sources than these example numbers. APR, escrow rules, and future taxes vary; this is not a personalized mortgage quote.
