How to use this calculator

This mortgage calculator (home loan calculator) estimates your monthly mortgage payment with taxes, insurance, PMI, HOA, and extra costs. It is optimized for U.S. borrowers and fixed-rate loans.

  1. Enter your home price. Use the purchase price (or current value if refinancing).
  2. Enter your down payment. Type a dollar amount or switch to percentage.
  3. Enter your loan term. 30, 20, 15, or 10 years are common.
  4. Enter your interest rate. Use your preapproval rate or today’s average (e.g., 6.15%).
  5. Click “Calculate”. Adjust property tax, home insurance, PMI, HOA, or other costs as needed.

Factors that affect your mortgage payment

  • Home price & down payment: Larger down payments cut the loan amount and may remove PMI if you reach 20%.
  • Interest rate: Small rate changes can shift total interest by tens of thousands over the loan life.
  • Loan term: Shorter terms mean higher monthly payments but far less total interest.
  • Taxes, insurance, HOA, PMI: These turn a base payment into a true “mortgage calculator with taxes and insurance.”

Mortgage calculator formula

We use the standard amortization formula for principal & interest:

M = P · [ r(1 + r)^n / ((1 + r)^n - 1) ]
M = monthly mortgage payment
P = loan principal
r = monthly interest rate (annual rate / 12)
n = total number of payments (months)

Understanding your results

  • Principal & Interest: Base mortgage payment.
  • Total cost of the loan: Sum of all payments from the amortization schedule.
  • Payoff date: When the balance reaches zero.
  • What-if scenarios: Try +0.5% rate, or add $100 extra per month to see payoff shift.

How much mortgage can I afford?

Use the 28/36 rule: keep housing =28% of gross income and total debt =36%. Example: $5,000 gross monthly income ? housing target ˜ $1,400. Use our affordability mode to test “how much mortgage can I afford.”

What to consider next

  • Time in home: If moving in ~5 years, an ARM may lower initial payments.
  • Total housing budget: Include maintenance, utilities, reserves.
  • Credit readiness: Improving credit can drop your rate and total interest.
  • DTI check: Lenders prefer total debt-to-income =36–43%.
