Mortgage Payment Calculator

Plan monthly mortgage payments with principal, interest, taxes, insurance, PMI, HOA, and amortization assumptions.

Built for home buyers comparing affordability scenarios before speaking with lenders.

Planning information only. Not a loan offer, loan estimate, underwriting decision, tax advice, or guarantee of payment amount.

Total-payment views must separate principal and interest from escrow items.

Loan Estimate education belongs beside the calculator, not hidden below the fold.

Live v1 supports user-entered taxes, insurance, PMI, HOA, and amortized payment results.

  • Uses user-entered taxes, homeowners insurance, PMI, HOA, rate, and term assumptions
  • Shows the as-of date for methodology and source references
  • Keep lender routing separate from payment calculations
  • Planning information only. Not a loan offer, loan estimate, underwriting decision, tax advice, or guarantee of payment amount.
  • The browser does not run calculator math or own financial assumptions.
  • No partner or commercial routing can change the product output.
