Estimated monthly housing cost
What a mortgage payment includes
A mortgage payment often starts with principal and interest. This calculator also lets you add property tax, home insurance, and monthly maintenance so you can compare loan payment with broader housing cost.
Formula
Principal and interest use the monthly reducing balance formula: M = P × r × (1 + r)^n / ((1 + r)^n - 1). Zero interest divides principal by number of payments.
Assumptions
Tax and insurance are divided by 12. Maintenance is added monthly. No closing costs, stamp duty, PMI, prepayments, or country-specific fees are automatically included.
Worked example
For a property priced at ₹50,00,000 with 20% down payment, loan principal becomes ₹40,00,000. A longer tenure can lower monthly principal and interest but usually increases total mortgage interest because the balance stays unpaid for more months.
Down payment and LTV
Loan-to-value compares loan principal with property price. Lower LTV means more equity from the down payment. This estimate does not say whether a lender will approve that LTV.
Frequently asked questions
Mortgage estimate answers reflect current calculator behaviour.
What does a mortgage payment include?
This calculator separates principal and interest from property tax, home insurance, and monthly maintenance entered by you.
Does it include closing costs or stamp duty?
No. It does not automatically add country-specific fees, closing costs, stamp duty, PMI, or lender charges.
How does down payment affect cost?
A larger down payment lowers loan principal and loan-to-value, which usually lowers monthly principal and interest.
Is this a lender quote?
No. It is a planning estimate using the values entered and documented assumptions.
