Should You Refinance to Drop PMI? Let's Check

First, what PMI really is

Let me clear up a misunderstanding I hear constantly. Private mortgage insurance — PMI — does not protect you or your home. It protects the lender in case you stop paying. When you buy with less than 20% down, the lender adds PMI to cover their risk, and you foot the bill. It's a perfectly normal cost of getting into a home with a smaller down payment, but it's not yours to keep paying forever.

On a typical loan, PMI might run $1,560 a year — that's $130 a month going to protect someone else's investment. Once you've built enough equity, getting rid of it is one of the easiest wins in homeownership. The only question is how.

The free path most people miss

Here's the thing that saves my clients the most money: if you have a conventional loan, you may not need to refinance at all.

Request removal at 20% equity

Once your loan balance drops to about 80% of your home's value — meaning you have roughly 20% equity — you can usually ask your loan servicer to cancel PMI. You may need to show that the home's value supports it, sometimes with a current appraisal. But there's no new loan, no fresh closing costs, and no reset term. You just stop paying PMI.

Automatic cancellation at 78%

By law, on most conventional loans the servicer must cancel PMI automatically once your balance reaches 78% of the original value, as long as you're current on payments. So even if you do nothing, PMI has an expiration date. If you're close, sometimes the smartest move is simply to wait.

Ask Jaime: A reader asked why anyone refinances to drop PMI if you can just ask. Great question. The free request only works on conventional loans once you've got the equity. Two big exceptions push people toward a refinance: FHA loans, and the chance to grab a lower rate at the same time. Let's take those one at a time.

When refinancing IS the right move

You have an FHA loan

This is the big one. On most modern FHA loans, the mortgage insurance premium doesn't cancel just because you build equity — it can stick around for the life of the loan. The standard way to escape it is to refinance out of the FHA loan into a conventional one once you have enough equity. For a lot of FHA borrowers, refinancing isn't optional for dropping the insurance; it's the only door.

You can also lower your rate

Even on a conventional loan, refinancing to drop PMI can be brilliant if you're also capturing a meaningfully lower rate. Now you're solving two problems with one set of closing costs: less interest and no PMI. When both line up, the math gets very attractive, very fast.

Your home jumped in value

Sometimes a home appreciates enough that a fresh appraisal shows you're already past 20% equity even if your loan balance alone wouldn't get you there. A refinance can lock in that new value and shed PMI right away.

Run the check before you spend

Whatever route you're considering, do the same break-even math I preach everywhere. Add up the closing costs of refinancing, divide by what you'll save each month — including the PMI you'd shed — and see how many months it takes to come out ahead.

If you can drop $130 of PMI plus, say, $170 from a lower rate, that's $300 a month. Against $6,000 in closing costs, you'd break even in 20 months. Stay in the home past that, and it's a clear yes. But if the only savings is the PMI and your servicer would remove it for free anyway, refinancing makes no sense at all.

My order of operations

Here's exactly how I'd check, step by step:

1. Conventional loan? Find out where your equity stands. If you're near 20%, request removal — it's free.
2. Close to 78% of original value? Consider just waiting for automatic cancellation.
3. FHA loan? A refinance into a conventional loan is likely your path out of the insurance.
4. Can you also lower your rate? Then a refinance does double duty and the math usually works.
5. Run break-even before committing either way.

The bottom line

PMI is the lender's safety net, paid for out of your pocket, and you don't have to carry it once you've built real equity. The cheapest way to drop it is often not a refinance — on a conventional loan, a simple request (or patience until automatic cancellation) costs nothing. Refinance to escape PMI when you're stuck in an FHA loan or when you can grab a lower rate in the same move. Check the free path first, and let the math decide the rest.
