Private Mortgage Insurance (PMI): What It Is and How to Avoid It

If you are buying a home with less than 20% down, there is a good chance private mortgage insurance — better known as PMI — will show up on your loan estimate. For many borrowers it adds $200 to $400 per month to the mortgage payment, yet most buyers have never had anyone explain what they are actually paying for.

In this guide we break down exactly what PMI is, who requires it, how much it really costs, four proven ways to avoid it, and the rules that let you get rid of it once your equity grows. By the end, you will be able to decide whether paying PMI is a smart trade-off or an expense worth engineering out of your loan.

What Is PMI and How Does It Work?

Private mortgage insurance is a policy that protects your lender — not you — if you stop making payments and the home goes into foreclosure. Studies consistently show that loans with small down payments default at higher rates, so lenders use PMI to shift part of that risk to an insurance company. This is what allows them to approve borrowers with just 3% to 10% down instead of demanding 20%.

The key facts:

• It applies to conventional loans. PMI is required on conventional mortgages whenever your down payment is below 20%, which means your loan-to-value ratio (LTV) starts above 80%.
• It protects the lender, not you. If you default, the insurer pays the lender's claim. You get no direct benefit from the coverage, although it does enable homeownership with a smaller down payment.
• It is added to your monthly payment. Most borrowers pay PMI in 12 equal installments bundled into their monthly mortgage bill. Some lenders offer a single upfront premium or a split premium instead.
• It does not last forever. Unlike FHA mortgage insurance, conventional PMI can be canceled once you build enough equity — more on that below.

Your exact PMI rate depends mainly on your credit score, your LTV, the loan term, your occupancy (primary home vs. investment property), and your debt-to-income ratio. Two neighbors with identical houses can pay very different PMI amounts purely because one has a higher credit score.

How Much Does PMI Cost?

PMI typically runs from 0.5% to 1.5% of the loan amount per year, divided into monthly payments. The precise rate comes from your credit profile and down payment size. Here is what that range looks like in real dollars across common loan sizes:

To see the math clearly, take a $300,000 loan with a 1% annual PMI rate: that is $3,000 per year, or $250 every month. Over just five years you would hand over $15,000 in insurance premiums that build zero equity for you.

Credit scores matter enormously here. A borrower at 90% LTV with a 760+ credit score might pay around 0.35%–0.5%, while the same loan at a 640 score could be quoted 1.25% or more — several times higher. Raising your credit score before applying is often the cheapest way to shrink PMI.

FHA Mortgage Insurance (MIP) vs. Conventional PMI

FHA loans carry their own insurance called a mortgage insurance premium (MIP), and the rules are very different from conventional PMI:

• MIP is required regardless of down payment. Even a 20% down FHA borrower pays it; there is no way to structure an FHA loan without mortgage insurance.
• There is an upfront premium of 1.75% of the base loan amount, usually rolled into the loan balance. On a $300,000 loan that is $5,250 added before you make your first payment.
• Annual MIP ranges from about 0.15% to 0.75%, depending on loan size, term, and LTV, paid monthly in 12 installments.
• MIP generally cannot be removed on most FHA loans originated after June 2013. If you put less than 10% down, MIP lasts for the life of the loan. Even with 10%+ down, it only ends after 11 years.

This is why many borrowers who start with an FHA loan later refinance into a conventional loan once they have 20% equity — it is often the only escape route from lifetime MIP. If you have decent credit, comparing both loan types side by side before buying is well worth the time.

4 Ways to Avoid Paying PMI

If PMI does not fit your budget, these are the main strategies lenders recognize:

• Put 20% down. The simplest answer. At 80% LTV no PMI is charged at all. The trade-off: tying up more cash and delaying your purchase while you save. Our down payments guide covers realistic timelines for getting there.
• Use a piggyback loan (80/10/10). You take a first mortgage for 80% of the price, a second loan (often a HELOC) for 10%, and put 10% down. No single loan exceeds 80% LTV, so no PMI is charged. The second loan carries a higher interest rate, but the total cost is often lower than PMI — and second-loan interest may be tax-deductible in ways PMI is not. Ask your lender to run both scenarios.
• Choose lender-paid PMI (LPMI). The lender covers the insurance cost in exchange for a higher interest rate on your loan. Your monthly payment may be lower than a PMI-plus-lower-rate option, but the catch is permanence: the elevated rate never drops off the way PMI does at 78% LTV, and it follows you unless you refinance.
• Use a VA or USDA loan. VA loans for eligible veterans and service members charge no monthly mortgage insurance at all — just a one-time funding fee. USDA rural-development loans also have no PMI, using a guarantee fee instead that is usually cheaper than conventional PMI.

How to Remove PMI From an Existing Loan

Conventional PMI is not forever. Federal law — the Homeowners Protection Act — gives you clear exit ramps:

• Request cancellation at 80% LTV. Once your balance reaches 80% of the home's original value, you can send a written request to your servicer. You must be current on payments and free of other liens on the home.
• Automatic termination at 78% LTV. If you do nothing, the servicer must automatically end PMI on the date your payments are scheduled to bring the balance to 78% of the original value — provided your account is current.
• Final termination at the loan midpoint. As a backstop, PMI must terminate at the halfway point of the amortization schedule (month 181 of a 30-year loan) regardless of balance.
• Fannie Mae and Freddie Mac current-value rules. If your home has appreciated, you may qualify sooner based on a new appraisal: generally 75% LTV within the first five years of the loan, or 80% LTV after five years.

Worked Example: $300,000 Home With 10% Down

Say you bought a $300,000 home with $30,000 down, giving you a $270,000 loan at 90% LTV. To hit the 80% cancellation threshold you must reach a balance of $240,000 — meaning you need to pay off $30,000 of principal.

On a 30-year fixed loan at 6.5%, your payment is about $1,707 per month, but early payments are mostly interest. Relying on scheduled amortization alone, the balance reaches $240,000 after roughly 95 months — close to eight years. Three things speed that up:

• Extra principal payments. Adding even $200 per month toward principal shaves well over a year off that timeline.
• Appreciation. If comparable homes in your area have risen in value, a reappraisal under Fannie/Freddie rules can prove 80% LTV long before your balance does.
• Refinancing. A refinance to a lower rate or shorter term resets the clock but can eliminate PMI immediately if the new LTV is at or below 80%.

Servicers do not always act promptly on automatic termination dates, so track your own amortization and speak up when you cross the line. Our refinance break-even guide explains how to check whether refinancing out of PMI also saves money overall.

Is PMI Worth It? Sometimes Yes

Paying PMI feels like throwing money away, but waiting years to save a 20% down payment has its own costs. Consider a $350,000 home:

• Option A — wait: You save three more years toward 20%. But if prices rise 4% per year, that home now costs about $394,000, so the required down payment grows from $70,000 to nearly $79,000 — while you keep paying rent the whole time.
• Option B — buy now with 10% down: You take a $315,000 loan and pay roughly $230–$260 per month in PMI. With normal amortization plus modest appreciation, you cross the 80% threshold within a few years, then the PMI disappears permanently. Total PMI paid: often under $10,000.

Between rising rents, growing home prices, and the fact that equity builds from day one when you own, many first-time buyers come out ahead accepting PMI now rather than saving until "someday." The right answer depends entirely on your local market, your rent, and your timeline — so model both paths with numbers before deciding.
