What is PMI (Private Mortgage Insurance)?

Private Mortgage Insurance (PMI) is typically required by lenders when a borrower puts down less than 20% on a conventional home loan. PMI protects the lender—not the borrower—in case the borrower defaults on the loan. However, it adds to your monthly mortgage costs and can affect your long-term affordability.

PMI rates vary depending on factors such as your credit score, loan-to-value (LTV) ratio, and the lender’s policies. On average, PMI ranges from 0.3% to 1.5% of the original loan amount annually.


What is a PMI Cost Calculator?

The PMI Cost Calculator is a financial tool that helps homeowners and mortgage applicants estimate their monthly PMI payments. By entering a few basic numbers—such as loan amount, down payment, and estimated PMI rate—you can instantly view how much you’ll pay in PMI every month.

This tool can be especially helpful in comparing different loan options, planning your monthly budget, or assessing how increasing your down payment could help you avoid PMI altogether.


How to Use the PMI Cost Calculator

Here’s a step-by-step guide to using the calculator effectively:

  1. Enter Loan Amount
    Input the total amount of money you’re borrowing through your mortgage. This is usually the purchase price of the home minus the down payment.
  2. Enter Down Payment
    Specify the amount of money you’re putting down. This value helps determine your loan-to-value (LTV) ratio, which affects your PMI cost.
  3. Enter PMI Rate (%)
    The PMI rate depends on your credit score, loan term, and LTV. Enter your expected PMI rate as a percentage (e.g., 0.5%).
  4. View Monthly PMI Cost
    The calculator multiplies the loan amount by the PMI rate and divides it by 12 to give you the estimated monthly PMI payment.

PMI Cost Formula

Here is the basic formula used by the calculator:

Monthly PMI Cost = (Loan Amount × PMI Rate) ÷ 12

Where:

  • Loan Amount is the principal balance of your mortgage.
  • PMI Rate is the annual rate charged for private mortgage insurance (usually between 0.3% and 1.5%).
  • 12 converts the annual rate into a monthly cost.

Example Calculation

Let’s say you’re buying a $300,000 home with a $30,000 (10%) down payment. Your loan amount would be:

$300,000 – $30,000 = $270,000

Assuming a PMI rate of 0.6%, the monthly PMI cost would be:

($270,000 × 0.006) ÷ 12 = $135/month

So, your estimated PMI payment would be $135 per month until you reach 20% equity in your home.


Helpful Insights

  • Avoiding PMI: If you make a 20% or higher down payment, you can avoid PMI entirely.
  • PMI Termination: PMI usually drops off automatically when your LTV reaches 78%, but you can request cancellation once you hit 80%.
  • Higher Credit = Lower PMI: Better credit scores qualify for lower PMI rates.
  • Loan Type Matters: FHA loans come with mortgage insurance but follow different rules than conventional loans.
  • Refinancing: If your home increases in value and you gain 20% equity, refinancing could remove PMI.
