Documentation

Calculate a clear monthly mortgage payment with principal and interest, property taxes, home insurance, HOA dues, and potential private mortgage insurance (PMI). Compare 15-year and 30-year mortgage options, test different down payments, and review a full amortization schedule to see how payments reduce your balance over time.

Enter your home price, down payment, interest rate, and loan term to see an accurate monthly payment. Adjust property tax, insurance, and HOA dues to reflect your location and policy details. View an amortization schedule to track how much of each payment goes to principal versus interest. Switch between monthly and yearly views to match your planning needs. Compare loan types to understand total interest paid and time to payoff. Use query parameters and saved settings to revisit scenarios quickly.

Identify an affordable home price by testing different down payment amounts and rates. Understand how PMI affects your payment when your down payment is below 20 percent of the home price. Evaluate the benefit of a 15-year mortgage, which usually reduces total interest but increases the monthly payment. Measure the long-term impact of small rate changes on total interest. Plan for taxes and insurance by adding realistic annual estimates that convert to monthly amounts.

  • Set the **Mortgage Value** to match a target purchase price or offer.
  • Enter **Down Payment** in dollars or percent to test scenarios that avoid PMI.
  • Select **Type of Mortgage** to compare 15-year, 30-year, or 5/1 ARM assumptions.
  • Input **Interest Rate** to reflect current market rates or pre-approval terms.
  • Add **Property Tax**, **Home Insurance**, **HOA Dues**, and **Other Costs** to complete your monthly estimate.

Evaluate a $400,000 home with a 10 percent down payment and a 30-year fixed rate to see how PMI affects the monthly payment and total lifetime cost. Increase the down payment to 20 percent and measure the change when PMI is removed. Switch to a 15-year term to compare higher monthly payments with significantly lower total interest. Adjust the interest rate by 0.5 percentage points and observe how the monthly payment and total interest shift. Add HOA dues and update home insurance to reflect a specific neighborhood or policy.

  • Confirm local **property tax** rates and update the annual amount for precision.
  • Check current **mortgage interest rates** from multiple lenders or a trusted aggregator.
  • Verify **homeowners insurance** estimates with your provider or an online quote.
  • Include **HOA dues** and any mandatory community fees to avoid surprises.

What is PMI and when does it apply? PMI is a lender protection fee that usually applies when your down payment is under 20 percent. The calculator shows PMI as a monthly cost when required.

How do taxes and insurance affect my payment? Property taxes and homeowners insurance are divided into monthly amounts and added to principal and interest to show a complete payment estimate.

How accurate are the results? Results reflect your inputs and standard mortgage formulas. Actual payments can differ based on lender fees, escrow practices, rate changes, and closing details.

Can I compare 15-year and 30-year loans? Yes. Select the loan type and compare monthly payments, total interest, and time to payoff. A shorter term usually saves interest but increases the monthly payment.
