How to Use This Mortgage Calculator

A mortgage payment has four parts: principal and interest on the loan itself, plus property tax and home insurance, which lenders usually collect monthly into an escrow account, plus any HOA fee. First subtract the down payment from the home price to get the loan amount, then work out the principal-and-interest part with the standard loan formula, then add one twelfth of the yearly tax and one twelfth of the yearly insurance. The total is the real monthly cost of the house, not just the loan.

Formula Used

The loan part uses the standard amortization formula; property tax and insurance are divided by 12 and added to the monthly principal-and-interest payment.

Worked Example

Example: Home price $400,000 · Down payment $80,000 · Term 30 years · Rate 6.5% · Tax 1.1% · Insurance $1,800/year · HOA $0

  1. Loan amount = $400,000 − $80,000 = $320,000.
  2. Principal and interest on $320,000 at 6.5% for 30 years = $2,022.62 a month.
  3. Property tax = $400,000 × 1.1% ÷ 12 = $366.67 a month; insurance = $1,800 ÷ 12 = $150.00 a month.
  4. Total monthly payment = $2,022.62 + $366.67 + $150.00 + $0 = $2,539.28.

Total Monthly Payment: $2,539.28

Frequently Asked Questions

What does PITI mean?

Principal, Interest, Taxes and Insurance — the four parts of a typical mortgage payment. This calculator adds all four, plus HOA if you enter one, so the total is the real monthly cost of the house.

How much down payment do I need?

It depends on the loan: many lenders want 20% to avoid PMI (private mortgage insurance), but some loans allow much less. A bigger down payment means a smaller loan, a smaller payment and less interest overall.

Does this calculator include PMI?

No. It includes principal, interest, property tax, insurance and HOA, but not PMI. If your down payment is under 20%, your lender may add PMI on top of the payment shown here.

Is a 15-year mortgage better than a 30-year one?

A 15-year loan usually has a lower rate and far less total interest, but the monthly payment is much higher. A 30-year loan costs more in total but is easier to afford month to month. Run both terms here and compare the total interest.
