How your monthly mortgage payment adds up
Your real monthly housing cost is far more than principal and interest. This calculator builds the full picture — the loan repayment plus property tax, home insurance, HOA dues, PMI, maintenance, and utilities — so you can see the true all-in number before committing to a home.
What goes into the payment
The core repayment (principal and interest) is fixed by your loan amount, interest rate, and term using the standard amortisation formula. On top of that sit property tax and insurance, any HOA fees, PMI if your down payment is under 20%, and the ongoing maintenance and utility costs that catch many first-time buyers off guard.
Ways to lower the monthly cost
A larger down payment shrinks the loan and removes PMI once you cross 20% equity. A longer term lowers the monthly payment but increases total interest, while a shorter term does the opposite. Even a small improvement in your interest rate can change the payment noticeably — try a few combinations to see the trade-offs side by side.
These figures are estimates to help you plan and are not a loan offer; your lender’s exact numbers depend on your credit, location, and loan product.
