Private Mortgage Insurance (PMI)
PMI is insurance that protects the lender — not you — if you default on your mortgage. Lenders require it when your down payment is less than 20% of the home price (i.e., your loan-to-value ratio exceeds 80%).
Key formula:
Monthly PMI = Loan Balance × Annual PMI Rate / 12
Typical PMI rates:
| LTV Ratio | Typical Annual PMI Rate |
|---|---|
| 95% – 97% | 0.90% – 1.50% |
| 90% – 95% | 0.60% – 1.10% |
| 85% – 90% | 0.40% – 0.80% |
| 80% – 85% | 0.20% – 0.50% |
PMI rate also depends on your credit score, loan type, and lender. Borrowers with lower credit scores pay higher PMI rates.
When does PMI end?
- Under the Homeowners Protection Act (HPA), you can request PMI cancellation when your LTV reaches 80% (either through payments or appreciation)
- PMI must be automatically cancelled when LTV reaches 78% based on the original amortization schedule
- FHA loans have different rules — MIP (Mortgage Insurance Premium) may last the life of the loan
LTV formula:
LTV = Loan Balance / Current Home Value × 100
Example:
- Home value: $350,000, Down payment: $17,500 (5%), Loan: $332,500
- LTV at closing: 95%, PMI rate: 1.0%
- Monthly PMI: $332,500 × 0.01 / 12 = $276.92/month
- PMI cancellation: when balance drops to $280,000 (80% of $350,000)
PMI is typically added to your monthly mortgage payment and held in escrow.
