Scenario: PMI Cost on a $400,000 Home Purchase
A buyer purchases a $400,000 home with a 5% ($20,000) down payment, leaving a $380,000 loan balance.
Step 1: The Loan-to-Value (LTV) is 95% — well above the 80% PMI removal threshold.
Step 2: With an excellent credit score, the estimated annual PMI rate is 0.65%.
Step 3: Annual PMI is $2,470, translating to $205.83 per month in mortgage insurance cost.
Step 4: PMI terminates once the balance amortizes down to $320,000 (80% LTV).

Frequently Asked Questions
Complete indexable directory of answers (8 questions)
How much is PMI on a mortgage?
PMI costs typically range from 0.3% to 1.5% of the loan amount annually. Use this PMI calculator with credit score to estimate your specific rate — lower credit scores and smaller down payments result in higher PMI costs.
When is PMI automatically removed from my mortgage?
Under federal law, your lender must automatically terminate PMI when your Loan-to-Value (LTV) ratio reaches 78% of the original purchase value, or when you reach the midpoint of your amortization schedule.
Can I remove PMI early if my home value increases?
Yes. If home values rise or you perform major renovations, you can request PMI cancellation based on a new appraisal once you have reached 20% equity. Use our PMI elimination calculator to project your timeline.
How can I avoid paying PMI?
You can avoid PMI by making a 20% down payment, using an 80/10/10 piggyback loan, choosing a VA loan (which has no PMI), or negotiating lender-paid PMI in exchange for a slightly higher interest rate.
Does my credit score affect my PMI rate?
Yes. Higher credit scores qualify for lower PMI rates. A buyer with a 760+ credit score may pay 0.4% annually, while a buyer with a 660 score might pay 1.0% or more. Use our PMI calculator with credit score to compare.
