Free interactive mortgage tool

Mortgage payment calculator

Estimate principal, interest, taxes, insurance, mortgage insurance, and community costs using assumptions you control.

How the tool works

Use the formula. Then challenge the assumptions.

The principal-and-interest payment is calculated from the loan amount, interest rate, and term. The complete housing payment then adds property taxes, homeowners insurance, flood insurance when applicable, mortgage insurance, HOA dues, and CDD or other community assessments.

A principal-and-interest estimate is not the complete housing payment when the property also has taxes, insurance, HOA, CDD, flood, or mortgage-insurance costs. Add every property-specific expense before using the result for planning.

Inputs to verify

The result is only as useful as the numbers.

  • Loan amount after the down payment
  • Interest rate and loan term
  • Property taxes based on a realistic post-purchase value
  • Address-specific homeowners and flood insurance
  • Mortgage insurance when applicable
  • HOA, condominium, CDD, and community assessments

Questions to ask

Before relying on the result

  • Does the tax estimate reflect the value after purchase or completion?
  • Was insurance estimated for the exact property?
  • Are HOA, condominium, CDD, and flood costs included?

This free planning tool provides an educational estimate. It is not a quote, approval, commitment to lend, or substitute for a Loan Estimate and documented mortgage review.
