Browser-based

Estimate monthly mortgage payments from home price, down payment, interest rate, and term. Optionally include property tax, home insurance, and HOA fees for a full monthly breakdown, plus total interest and cost over the loan.

Monthly payment estimates exclude HOA, PMI changes, escrow adjustments, and property tax reassessments. Not a loan offer or pre-approval.

What to do next

How to use this tool

1. Enter home price, down payment, APR, and loan term in years. 2. Add optional annual property tax, home insurance, and monthly HOA. 3. Click Calculate mortgage. 4. Review total monthly payment and principal-and-interest split. 5. Enable scenario compare to contrast 15-year vs 30-year or different down payments.

Worked example

Example: a home near $400,000 with about 20% down, a mid-6% APR, and a 30-year term plus typical tax and insurance inputs often lands near $2,400–$2,700/month total—your lender’s escrow and rate quote may differ.

How it works

Enter the home price, down payment, interest rate, and term. The calculator derives the loan amount and uses the standard amortizing loan formula for principal and interest. Optional annual property tax, home insurance, and monthly HOA fees are added to estimate a total monthly payment. Fees, PMI, and taxes beyond your inputs are not included.

Limitations

Monthly payment estimates exclude HOA, PMI changes, escrow adjustments, and property tax reassessments. Not a loan offer or pre-approval.

Accuracy & methodology

This section documents how the calculator works, what it leaves out, and when results were last reviewed. Figures are educational estimates—not professional advice—and are not labeled "current" unless tied to automatically updated reference data.

Formula source or methodology
Loan amount = home price − down payment. Monthly principal & interest uses the standard amortizing loan payment formula (same as loan calculator). Optional annual property tax, insurance, and HOA are divided by 12 and added to P&I for total monthly housing payment.
Jurisdiction
General mortgage math (not country-specific underwriting rules)
Unit system
Currency for price, down payment, tax, insurance, HOA; years for term; percent for rate
Rounding method
Currency amounts round to two decimal places (half up via Math.round × 100 / 100).
Assumptions
  • Fixed annual interest rate for the full term
  • Level monthly payments (fully amortizing)
  • Down payment is a dollar amount, not a separate percent field
Known omissions
  • Not tax, legal, investment, or lending advice. Confirm material decisions with qualified professionals.
  • Origination fees, points, PMI/MIP, and lender-specific charges unless a field exists
  • Property taxes, insurance, and HOA unless explicitly entered
  • Prepayment penalties and variable or adjustable rates after the initial period
  • Tax deductibility of interest
Test cases (automated)
  • Typical home price, down payment, rate, and term return positive P&I and total interest
  • Down payment greater than home price is rejected

Frequently asked questions

What is included in the total monthly payment?

Total monthly payment combines principal and interest with optional monthly shares of property tax, home insurance, and HOA fees.

How is the loan amount calculated?

Loan amount is the home price minus the down payment. The down payment must be less than the home price.

Does this include PMI or closing costs?

No. Results are estimates based on your inputs. PMI, closing costs, and other lender fees are not included.
