Definition

In one sentence about Private Mortgage Insurance (PMI)

Private mortgage insurance (PMI) is insurance that protects the lender if you default on your mortgage. It is required on conventional loans when your down payment is less than 20% of the home's purchase price. PMI typically costs 0.5% to 1.5% of the original loan amount per year, added to your monthly mortgage payment.

01

Why Understanding PMI Matters

PMI can add a significant cost to your monthly mortgage payment. On a $350,000 loan, PMI at 0.75% costs approximately $219 per month, or $2,625 per year. Over the years it takes to build 20% equity, PMI can cost $10,000-$25,000 in total. This is money that protects the lender, not you. Understanding when PMI is required, how it is calculated, and when you can remove it helps you plan your finances and potentially save thousands. The Homeowners Protection Act of 1998 gives borrowers the right to request PMI cancellation once they reach 20% equity (80% loan-to-value ratio), and requires lenders to automatically cancel PMI when equity reaches 22%. Knowing these thresholds and tracking your equity can help you eliminate this cost as soon as possible.

Real-World Example: PMI Costs by Loan Amount

Here is how PMI costs vary based on your loan amount and PMI rate. PMI rates depend on your credit score, down payment percentage, and loan type:

PMI Cost Calculation

PMI is calculated as a percentage of the original loan amount: Annual PMI = Loan Amount x PMI Rate. Monthly PMI = Annual PMI / 12. The PMI rate itself depends on your credit score and loan-to-value (LTV) ratio. Borrowers with credit scores of 760+ and an LTV of 85% pay the lowest PMI rates (around 0.3-0.5%). Borrowers with scores below 680 and an LTV of 95% or higher may pay 1.0-1.5% or more. For a $380,000 loan at 0.75% PMI: Annual PMI = $380,000 x 0.0075 = $2,850. Monthly PMI = $2,850 / 12 = $237.50.

When PMI Applies and How to Remove It

PMI applies in these situations and can be removed through these methods:

  • Conventional loan with less than 20% down: PMI is automatically required. It can be borrower-paid monthly, lender-paid (built into the rate), or paid as a single upfront premium
  • Request cancellation at 80% LTV: Under the Homeowners Protection Act, you can request PMI removal when your mortgage balance reaches 80% of the original home value. You must be current on payments and may need a new appraisal
  • Automatic termination at 78% LTV: Your lender must automatically cancel PMI when your loan balance reaches 78% of the original purchase price, based on the original amortization schedule
  • Home value appreciation: If your home has increased in value, you may reach 20% equity sooner than your amortization schedule suggests. Request a new appraisal to demonstrate the higher value
  • Extra principal payments: Making additional payments toward principal accelerates your path to 20% equity, allowing you to request PMI removal sooner

Common PMI Mistakes

Avoid these errors related to private mortgage insurance:

  • Not requesting PMI removal at 80% LTV: Many borrowers continue paying PMI long after reaching 20% equity because they do not know they can request its removal. Track your equity and submit a written request as soon as you hit 80% LTV
  • Confusing PMI with FHA mortgage insurance: FHA mortgage insurance premium (MIP) has different rules. On FHA loans with less than 10% down, MIP lasts the life of the loan and cannot be cancelled. You must refinance to a conventional loan to eliminate it
  • Not factoring PMI into affordability calculations: When comparing homes and loan amounts, include PMI in your monthly payment estimates. It can add $100-$500+ per month
  • Choosing lender-paid PMI without understanding the trade-off: Lender-paid PMI eliminates the monthly charge but results in a higher interest rate for the life of the loan. It cannot be removed through a request since it is built into the rate
  • Not improving credit before applying: A higher credit score significantly reduces your PMI rate. Improving from 680 to 760 could cut your PMI cost nearly in half
In short

PMI is a cost of buying with less than 20% down, but it is not permanent on conventional loans. Track your home equity and request PMI removal as soon as you reach 80% LTV. Improve your credit score before applying to secure the lowest PMI rate, and factor PMI into your monthly budget when determining how much home you can afford. If you have an FHA loan with lifetime MIP, consider refinancing to a conventional loan once you have 20% equity.

Common questions

Frequently asked questions

Is PMI tax deductible?

PMI tax deductibility has been intermittently available through temporary legislation. Congress has extended and allowed the deduction to lapse multiple times. Check the current tax year's rules or consult a tax professional to determine if PMI is deductible for your situation. When available, the deduction phases out at higher income levels.

How long do I have to pay PMI?

On a conventional loan, you pay PMI until you reach 20% equity (80% LTV) and request cancellation, or until the lender automatically cancels it at 22% equity (78% LTV). On a typical 30-year mortgage with 5% down, this takes approximately 7-10 years through regular payments alone. Extra principal payments can shorten this timeline significantly.

Can I avoid PMI with less than 20% down?

Yes, through several strategies: piggyback loans (80/10/10 structure where a second loan covers part of the down payment), lender-paid PMI (rolled into a higher interest rate), VA loans (no PMI for eligible borrowers), or some credit union and community bank programs that waive PMI for qualified borrowers.

Is PMI the same as homeowners insurance?

No. PMI protects the lender if you default on the loan. Homeowners insurance protects you against property damage, theft, and liability. Both are typically required by mortgage lenders, but they serve entirely different purposes. Homeowners insurance remains required for the life of the loan, while PMI can be removed.
