Educational Mortgage Tool

Mortgage payment estimator

Build a fuller monthly housing estimate with the assumptions visible. The result is not qualification, approval, a rate quote, or a commitment to lend.

Your assumptions

Enter property and loan estimates

Estimated purchase price—not a property valuation.
Cash applied to price. Closing costs are separate.
Enter your own assumption. No current or available rate is provided by this calculator.
Number of years used for principal-and-interest amortization.
Use a property-specific estimate; current owner taxes may not predict future taxes.
Use an insurance quote when available.
Enter zero only when no flood-insurance amount is being modeled.
Include mandatory association dues for the property.
Convert any annual CDD amount to a monthly estimate.
Enter a current estimate when the proposed structure includes it.

Calculation logic

How the estimate is calculated

Estimated loan amount = home price − down payment

Monthly rate = annual interest rate ÷ 100 ÷ 12

Number of payments = loan term in years × 12

Principal & interest = L × [r(1+r)n] ÷ [(1+r)n−1]

When the entered rate is 0%, principal and interest = loan amount ÷ number of payments.

Estimated total = principal and interest + monthly taxes + monthly homeowners insurance + monthly flood insurance + HOA/condo dues + CDD + mortgage insurance.

What it includes

A payment framework—not a loan decision

  • Amortized principal and interest using the entered rate and term
  • Annual taxes and insurance divided by 12
  • Monthly HOA, CDD, and mortgage-insurance estimates

Not included: closing costs, prepaid items, initial escrow funding, discount points, lender credits, seller credits, assistance, financed funding fees, special assessments, maintenance, utilities, rate changes, or program-specific adjustments unless the user manually reflects them in an input.

General education: Use the calculator to compare assumptions and identify which inputs matter.

Borrower-specific review: Gary must review current pricing, documentation, program, borrower, and property information before providing a personalized scenario. Sensitive records belong only in the approved secure system.
