Conventional Loan PMI Explained: How Private Mortgage Insurance Works in 2026

Summary:

Private mortgage insurance (PMI) protects the lender—not the borrower—if a homeowner defaults on a conventional loan with less than 20% down. While PMI increases monthly costs, it enables buyers to purchase homes sooner and can usually be removed once you reach 20% equity.

Private mortgage insurance (PMI) is a key cost consideration for anyone getting a conventional mortgage loan with a down payment under 20%. PMI makes low-down-payment conventional loans possible by reducing the lender’s risk. But understanding how it works—and how to cancel it—can save you thousands over the life of your loan.

What Is Private Mortgage Insurance (PMI)?

PMI is insurance that protects the lender if you stop making mortgage payments. You pay it as part of your monthly mortgage costs until you reach enough home equity to remove it.

Who it protects: The lender, not the borrower.
When it applies: Required on most conventional loans with less than 20% down.
When it ends: You can usually cancel PMI once your loan-to-value (LTV) ratio hits 80%.

Good to Know: PMI is not the same as homeowners insurance or mortgage protection insurance. It’s strictly designed to reduce lender risk—not to cover your home or loan payments.

Types of PMI for Conventional Loans

There are several PMI structures to choose from, depending on your financial goals and lender options.

PMI Type	How It’s Paid	Best For
Borrower-Paid PMI (BPMI)	Monthly payment added to mortgage until canceled at 80% LTV.	Most common; flexible and cancelable.
Lender-Paid PMI (LPMI)	Built into your interest rate instead of a separate fee.	Borrowers wanting a lower monthly payment but don’t mind higher interest.
Single-Premium PMI	One-time upfront payment at closing.	Those with extra cash who want to avoid monthly PMI charges.
Split-Premium PMI	Partial upfront payment plus reduced monthly cost.	Buyers who want balance between lower rate and manageable cash outlay.

Your down payment size directly affects whether you’ll need PMI and how long you’ll pay it. Learn more about minimum down payment options and how they impact costs in our Conventional Loan Down Payment Options guide.

How Much Does PMI Cost?

PMI costs vary depending on your credit score, down payment, and loan amount. It’s typically charged as an annual percentage of the loan balance—divided into monthly payments.

Average PMI range: 0.3% to 1.5% of the loan balance per year.
Example: On a $400,000 loan with 10% down, PMI might cost $100 to $400 per month.
Lower PMI rates: Higher credit scores and larger down payments qualify for cheaper PMI premiums.

Smart Move: Before locking your rate, ask lenders for a detailed Loan Estimate that separates PMI costs. Comparing offers can reveal big differences between lenders’ PMI pricing.

When and How to Remove PMI

You can cancel PMI once you reach sufficient equity in your home. Federal law (Homeowners Protection Act) provides clear guidelines for removal:

Automatic cancellation: When your LTV ratio reaches 78% based on your original amortization schedule.
Borrower-requested cancellation: You can request removal at 80% LTV, typically supported by a new appraisal.
Refinancing: If your home value has increased, refinancing into a new loan may remove PMI sooner.

Example: PMI Over Time

Loan Amount	Down Payment	PMI Rate	Monthly PMI	Months Until 80% LTV*
$400,000	10% ($40,000)	0.7%	$233	~52 months
$400,000	5% ($20,000)	1.0%	$317	~88 months
$400,000	3% ($12,000)	1.3%	$430	~104 months

*Estimates based on typical amortization and no extra principal payments.

Alternatives to PMI

If you want to avoid PMI altogether, here are some common strategies:

Put 20% down: Avoid PMI entirely and get better loan terms.
Use a “piggyback” loan: Combine an 80% first mortgage with a 10% second mortgage (known as an 80-10-10 structure).
Choose Lender-Paid PMI (LPMI): Accept a slightly higher interest rate instead of a monthly PMI charge.
Consider an FHA loan or VA loan: These may offer lower total costs depending on your situation.

FAQs

Can I avoid PMI on a conventional loan?

Yes. You can avoid PMI by putting 20% down, using a piggyback loan, or choosing a lender-paid PMI option with a slightly higher interest rate.

How long do I have to pay PMI?

Typically until your loan-to-value ratio reaches 80%. It’s automatically removed at 78% unless you request earlier cancellation.

Is PMI tax-deductible?

PMI deductions have varied over the years. Check current IRS guidelines or consult a tax professional to see if you qualify for a deduction.

Does refinancing remove PMI?

Yes—if your home has appreciated or you’ve paid down your balance, refinancing into a new loan at 80% or lower LTV can eliminate PMI.

Is PMI required on all conventional loans?

Only if your down payment is below 20%. Loans at or above 20% down do not require PMI.
