What You'll Really Pay For Private Mortgage Insurance

Nobody tells you what PMI actually costs until you’re three days from closing and staring at a loan estimate that suddenly looks different than you expected.

I’ll be honest: even after 16 years in underwriting, I was surprised by how wide the range is when I went back and pulled current data on this. Most borrowers I worked with assumed PMI was a flat, modest fee, maybe $50 a month, and they’d barely notice it. The reality is messier, and the factors that drive your specific premium are ones most loan officers either don’t explain well or don’t explain at all.

So let me give you the actual numbers, the math behind them, and the fine print that matters.

What PMI Actually Costs Per Month, in Real Numbers

As of June 2026, PMI typically runs between 0.5% and 1.5% of your original loan amount per year, paid monthly. That’s the range you’ll see quoted most often, and it’s accurate as a starting point. But inside that range there’s enormous variation, and where you land depends on your down payment, your credit score, your loan type, and the specific insurer your lender uses.

Here’s what that looks like in practice:

• A $350,000 loan at 0.5% PMI rate = $145.83/month
• A $350,000 loan at 1.0% PMI rate = $291.67/month
• A $350,000 loan at 1.5% PMI rate = $437.50/month

That’s nearly a $300/month swing on the same loan amount. Think about that for a second. On a 30-year mortgage, the difference between a 0.5% and a 1.5% PMI rate could cost you an additional $20,000+ before you hit the 80% loan-to-value threshold and can finally drop it.

What pushes you toward the higher end? Credit score below 680, loan-to-value ratio above 90% (meaning a down payment under 10%), and certain property types like condos or investment properties all push your rate up. What keeps you at the lower end? Strong credit (740+), a down payment between 10% and 19.99%, and a single-family primary residence.

What surprised me when I compared quotes from multiple private mortgage insurers was how little standardization there is. MGIC, Radian, Essent, and Arch MI all price risk a little differently. Your lender typically has relationships with one or two of these and won’t necessarily shop for the cheapest rate on your behalf. You can ask who the insurer is and request the rate card, but few borrowers know to do that.

The Credit Score Factor Most People Underestimate

I thought for years that the difference between a 700 and a 750 credit score was worth maybe $10 or $15 a month on PMI. I was wrong, and it cost a client of mine real money.

A borrower I was working with in the refinance department had a 702 score on a $400,000 loan with 8% down. Her PMI quote came in at 1.10% annually, which was $366/month. Six months later, after paying down a credit card and getting a score of 748, she refinanced and the PMI rate dropped to 0.54%, which was $180/month. That’s $186 a month in savings just from a 46-point credit score improvement. Over two years, she recovered more than $4,400.

The Consumer Financial Protection Bureau (CFPB) has a solid breakdown of how PMI gets priced and what rights you have as a borrower under the Homeowners Protection Act of 1998, including when lenders are required to cancel it automatically. Worth reading before you close.

The credit score tiers that matter most for PMI pricing are generally: below 640 (brutal), 640-679 (expensive), 680-719 (moderate), 720-759 (better), 760+ (best available rates). Different insurers draw the lines slightly differently, but these are the buckets I saw in practice.

Lender-Paid PMI: The Option That Sounds Better Than It Is

Here’s where I get a little skeptical, because this product drove me crazy as an underwriter.

Lender-paid PMI (LPMI) is when your lender covers the mortgage insurance premium in exchange for a slightly higher interest rate on your loan. It gets marketed as “no PMI” sometimes, which is technically true in the sense that there’s no separate line item on your statement. But you’re absolutely still paying for that insurance, just baked into your rate forever.

With borrower-paid PMI (BPMI), you can cancel it once you hit 20% equity. With LPMI, you can’t. The higher rate is permanent unless you refinance. If you’re planning to sell or refinance within five years, LPMI can make mathematical sense. If you’re staying in the home for 10+ years, borrower-paid PMI almost always wins. Run the numbers both ways before you let a loan officer steer you toward “no PMI” as if it’s obviously better.

A worked example here helps: $380,000 loan, 10% down, choice between BPMI at 0.85% ($269/month) or LPMI with a rate increase of 0.375%. At a base rate of 7.0%, the LPMI option would cost roughly $98/month more in interest (permanently). At the BPMI option, the borrower reaches 20% equity in about seven years (on a normal amortization schedule with modest appreciation) and cancels PMI. Over 10 years: BPMI total PMI cost roughly $19,300, then gone. LPMI extra interest cost at 10 years: roughly $11,760, but it never stops. By year 12, LPMI has cost more, total.

How to Get PMI Removed (and When Your Lender Doesn’t Tell You)

The Homeowners Protection Act requires automatic PMI cancellation when your loan balance reaches 78% of the original purchase price based on your scheduled payments, assuming you’re current. It also allows you to request cancellation when you reach 80% LTV. Note: this is based on your original purchase price, not the current market value, unless you order a new appraisal.

This is a detail servicers don’t advertise loudly. If your home has appreciated significantly, you may be able to request cancellation earlier by paying for an appraisal (typically $400-$600) to establish the new value. I’ve seen borrowers with homes that appreciated 20%+ in two years still paying PMI because they didn’t know they could request early cancellation.

If you want professional guidance on this process, HUD-approved housing counselors can walk through your options at no cost. That’s an underused resource.

For borrowers who want to go deep on the math before their next conversation with a lender, the Mortgage Encyclopedia by Jack Guttentag is one of the few books I’ve kept on my shelf for years. Dense but accurate. (Note: the site may earn a commission on purchases through this link.)
