What Is PMI on a Mortgage? A Complete Explanation

If you’ve been researching mortgages, you’ve probably come across the term PMI and wondered exactly what it means and why it might apply to you. PMI, or Private Mortgage Insurance, is one of the most common extra costs homebuyers encounter — and understanding it can help you plan your down payment strategy more effectively.

What Does PMI Actually Cover?

Private Mortgage Insurance protects the lender, not the borrower, in case you default on your loan. It doesn’t pay off your mortgage or protect your credit if you fall behind — its sole purpose is to reduce the lender’s financial risk when a borrower makes a smaller down payment.

Because a smaller down payment means the lender is financing a larger share of the home’s value, PMI acts as a safety net that allows lenders to approve loans they might otherwise consider too risky.

When Is PMI Required?

PMI is typically required on conventional loans when your down payment is less than 20% of the home’s purchase price. This threshold exists because, historically, a 20% down payment has represented enough of a cash cushion to significantly lower the lender’s risk of loss in a default scenario.

It’s worth noting that PMI applies specifically to conventional loans. Government-backed loans have their own separate mortgage insurance structures:

• FHA loans require Mortgage Insurance Premium (MIP), which works differently and, in many cases, cannot be cancelled without refinancing.
• VA loans don’t require monthly mortgage insurance at all, though they do include an upfront funding fee.
• USDA loans have their own guarantee fee structure, distinct from PMI.

How Much Does PMI Cost?

PMI typically costs between 0.3% and 1.5% of your original loan amount per year, though the exact rate depends on your credit score, down payment size, and loan term. On a $320,000 loan, that could mean anywhere from roughly $80 to $400 per month.

Higher credit scores generally result in lower PMI rates, similar to how they affect your interest rate — lenders view stronger credit profiles as lower risk.

How to Avoid Paying PMI

There are a few practical ways to avoid PMI altogether:

1. Put down 20% or more. This is the most straightforward way to skip PMI entirely on a conventional loan.
2. Consider a piggyback loan (80-10-10). Some borrowers take out a second loan to cover part of the down payment, keeping the primary loan at 80% loan-to-value and avoiding PMI — though this adds complexity and a second monthly payment.
3. Look into lender-paid PMI. Some lenders offer to cover PMI in exchange for a slightly higher interest rate. This can simplify your monthly payment, though it usually costs more over time than borrower-paid PMI that’s eventually cancelled.
4. Explore VA loans, if eligible. Veterans and eligible service members can often avoid mortgage insurance entirely through VA loan programs.

How to Remove PMI Once You Have It

If you’re already paying PMI, you’re not stuck with it forever. Under the U.S. Homeowners Protection Act, lenders are generally required to automatically cancel PMI once your loan balance reaches 78% of the home’s original value, assuming your payments are current.

You can also request PMI removal earlier, once your balance reaches 80% of the original value, though this typically requires a formal request and sometimes a new appraisal to confirm your equity position — especially if your request is based on the home’s current market value rather than your payment schedule alone.

Is PMI Worth It?

For many buyers, PMI is simply the cost of buying sooner rather than waiting years to save a full 20% down payment — especially in markets where home prices are rising faster than typical savings rates. Rather than viewing PMI as a bad deal, it’s often more useful to think of it as the price of entry for a smaller down payment, weighed against the opportunity cost of waiting to buy.
