Private mortgage insurance (PMI) is coverage that protects your lender if you default on your loan. You pay for it, typically as part of your monthly mortgage payment, when you put down less than 20% of the home's purchase price. PMI doesn't protect you or build equity. It exists to offset the lender's risk so they can approve loans with smaller down payments.
The coverage doesn't last forever. Once you reach 20% equity in the home through payments or appreciation, you can request cancellation. At 22% equity, federal law requires most lenders to cancel it automatically.
Why Lenders Require PMI
When you put down less than 20%, the lender has less cushion if you stop making payments. PMI compensates the lender for that added risk, making it possible for buyers to move forward without waiting years to save a full 20% down payment.
Most conventional loans require PMI when your down payment is below that threshold. Government-backed loans have their own versions of mortgage insurance, structured differently but serving the same purpose. FHA loans, for example, include an upfront insurance premium and an annual premium that often lasts the life of the loan, while VA loans charge a one-time funding fee instead.
How Much PMI Costs
PMI premiums vary based on your down payment, credit score, and loan amount. A larger down payment or higher credit score usually results in a lower premium. The rate is calculated as a percentage of your original loan amount and is typically divided into monthly installments.
For context, a lower down payment generally means a higher rate, and a borrower with a 5% down payment will pay more than someone putting down 15%. The monthly cost gets folded into your total mortgage payment alongside principal, interest, property taxes, and homeowners insurance. You won't see it as a separate bill, but it does increase what you owe each month.
Your lender provides the exact rate and monthly amount during the approval process. If the premium feels high relative to your budget, adjusting your down payment or working on your credit before applying may lower it. You can also explore whether your credit score affects the loan options available to you before committing to a loan structure.
When PMI Can Be Removed
You can request cancellation once your loan balance drops to 80% of the home's original appraised value. That typically happens after several years of payments, though if your home appreciates quickly, you may reach 20% equity sooner.
To request removal, contact your lender. Most will require proof that the home's value hasn't declined, which may involve a new appraisal. You'll also need to have a solid payment history with no recent late payments.
At 78% loan-to-value (22% equity), lenders must automatically cancel PMI under the Homeowners Protection Act, as long as your payments are current. Even if you never ask, the coverage should fall off once you hit that threshold. If it doesn't, follow up.
Ways to Avoid PMI
Putting down 20% or more eliminates the need for PMI entirely. That's not always realistic, but if you're close, waiting a few more months to save may reduce your total monthly cost enough to make it worthwhile.
Another option is a piggyback loan, where you take out a second mortgage to cover part of the down payment. You might put down 10%, take a primary mortgage for 80%, and use a second loan for the remaining 10%. This avoids PMI, though it means managing two loans with potentially different rates and terms.
Some lenders offer lender-paid mortgage insurance (LPMI), where the lender covers the insurance cost in exchange for a higher interest rate. You won't see a separate PMI line item, but the rate increase usually adds up to more over the life of the loan. LPMI can make sense if you plan to refinance or sell within a few years, but it's harder to remove than borrower-paid PMI.
VA loans and USDA loans don't require PMI at all, though they have their own fees or ongoing premiums. If you qualify for either program, they're often better deals than a conventional loan with PMI.
How PMI Affects Your Monthly Payment
PMI increases your monthly payment without building equity or reducing your loan balance. It's purely an insurance cost. That means a larger share of your budget goes toward housing without moving you closer to owning the home outright.
The difference can add up over time. If you're comparing loan scenarios, calculate what your payment looks like with and without PMI, then figure out how long it will take to cancel the coverage. That timeline helps you understand the real cost and decide whether a smaller down payment still makes sense.
In some cases, stretching to avoid PMI means a tighter monthly budget overall. In others, paying PMI for a few years is preferable to delaying homeownership. The right choice depends on your savings, income stability, and how long you plan to stay in the home. If you're weighing those factors, understanding what impacts your monthly mortgage payment can clarify where PMI fits in the bigger picture.
What Happens If You Refinance
Refinancing replaces your existing loan with a new one, and PMI doesn't automatically carry over. If your new loan amount is 80% or less of the home's current value, you won't need PMI on the refinance. That can happen if your home has appreciated or you've paid down enough of the original balance.
If you're still below 20% equity, the new loan will likely require PMI again. The rate may differ based on your current credit score, loan amount, and market conditions. Refinancing specifically to drop PMI can make sense if your home value has increased enough to push you over the 20% equity mark, but you'll need to weigh the closing costs against the monthly savings.
When PMI Makes Sense
PMI isn't ideal, but it's not always avoidable or even undesirable. If you're ready to buy and don't have 20% saved, PMI lets you move forward rather than wait another year or two while home prices and interest rates shift.
The coverage also doesn't last forever. Once you hit 20% equity, you can remove it and keep the loan. That's different from some government loan programs, where insurance premiums may never go away. If you expect your income or home value to rise, paying PMI for a few years may be a reasonable trade-off.
What matters most is understanding the total cost, how long you'll carry it, and whether the timing works for your situation. PMI is a tool that makes homeownership accessible earlier. Whether it's worth it depends on your timeline, your budget, and what alternatives you have.
If you're trying to figure out which loan structure fits your down payment and monthly budget, a loan officer can walk through the options with you and show what PMI looks like in real numbers. You can explore how much house you can afford to see where PMI would fit into your overall mortgage payment.
