Private Mortgage Insurance (PMI) Calculator: Complete Guide
Private Mortgage Insurance (PMI) is one of the most misunderstood aspects of home buying. When you put down less than 20% on a home, lenders require this insurance to protect themselves if you default on your loan. This comprehensive guide breaks it all down.
What is PMI?
PMI stands for Private Mortgage Insurance. It's insurance that protects your lender, not you. When you make a down payment of less than 20% of your home's purchase price, lenders consider your loan riskier. PMI reduces that risk for them.
Real Example:
If you buy a $300,000 home with 10% down ($30,000), you're borrowing $270,000. Your loan-to-value (LTV) ratio is 90%. Since this is above 80%, you'll need PMI.

How to Use the Calculator
Home Value
The current market value or purchase price. Example: $300,000
Loan Amount

The PMI Formulas
Loan-to-Value (LTV) Ratio
Example: ($270,000 ÷ $300,000) × 100 = 90%
Monthly PMI Calculation
Monthly PMI = Annual PMI ÷ 12
Example: $270,000 × 0.005 = $1,350 ÷ 12 = $112.50
