Understanding Private Mortgage Insurance (PMI): Costs & How to Avoid It

Last updated: May 2026

Private mortgage insurance, often called PMI, is an extra mortgage cost that may apply when you buy a home with a smaller down payment on a conventional loan. PMI can help borrowers buy sooner, but it also increases the monthly payment and should be included when you estimate affordability, closing costs, and long-term homeownership expenses.

This guide explains what private mortgage insurance is, how PMI affects your payment, when it may be required, how it can be removed, and practical ways to avoid or reduce it. You can also use the Mortgage Planning Tools hub and the Mortgage Calculator to estimate the full monthly payment before choosing a loan.

What Is Private Mortgage Insurance?

Private mortgage insurance is insurance that protects the lender if a borrower stops making mortgage payments. It is usually connected to conventional loans when the borrower has a smaller down payment.

The CFPB explains that PMI is a type of mortgage insurance you may be required to buy if you take out a conventional loan with a down payment of less than 20% of the purchase price, and that PMI protects the lender, not the borrower. Review the CFPB explanation of private mortgage insurance.

PMI is different from homeowners insurance. Homeowners insurance helps protect the property. PMI helps protect the lender’s risk on a lower-down-payment mortgage.

Why PMI Exists

Lenders view smaller down payments as higher risk because the borrower starts with less equity in the home. PMI helps offset that lender risk and may allow borrowers to qualify with less money down than a traditional 20% down payment.

This can be helpful for buyers who have steady income but have not saved a large down payment yet. However, the tradeoff is that the monthly mortgage payment may be higher.

The right choice depends on whether buying sooner with PMI is better than waiting longer to avoid PMI. That decision should include home prices, rent costs, savings rate, interest rates, monthly affordability, and emergency cash.

When Is PMI Usually Required?

PMI is commonly required on conventional mortgages when the down payment is less than 20%. In refinance situations, PMI may also apply if the homeowner has less than 20% equity.

A smaller down payment does not automatically mean the loan is bad. It simply means you should include PMI in the affordability calculation and know when it may be removable.

PMI vs. FHA Mortgage Insurance

PMI usually refers to private mortgage insurance on conventional loans. FHA loans use mortgage insurance too, but FHA mortgage insurance follows different rules and may not work the same way as conventional PMI.

Fannie Mae notes that PMI is associated with conventional mortgage loans, while FHA mortgage insurance is associated with FHA loans, and FHA mortgage insurance may be more complicated to remove. Review Fannie Mae’s PMI overview.

This is important because two loans with similar monthly payments may have different insurance rules, cancellation options, upfront costs, and long-term costs.

How PMI Affects Monthly Payment

PMI increases the monthly mortgage payment unless it is paid upfront or handled through another pricing structure. This can affect your affordability, debt-to-income ratio, and cash flow after closing.

PMI is usually not the largest part of the mortgage payment, but it can still be large enough to change the budget. A home that looks affordable using principal and interest alone may feel less comfortable once PMI, taxes, insurance, and escrow are included.

What Determines PMI Cost?

PMI cost can vary by borrower, property, lender, loan structure, and market conditions. Factors that may affect PMI pricing include:

• Down payment percentage.
• Loan amount.
• Loan-to-value ratio.
• Credit profile.
• Loan type.
• Loan term.
• Whether the loan has a fixed or adjustable rate.
• Whether PMI is monthly, upfront, lender-paid, or split premium.

Freddie Mac offers a PMI calculator that can help estimate monthly private mortgage insurance based on down payment amount, while noting that borrowers should contact their lender for precise calculations. Review Freddie Mac’s PMI calculator.

Common Ways PMI Is Paid

PMI may be paid in different ways depending on the loan and lender options. Each option affects upfront cost, monthly payment, or interest rate differently.

Ask the lender to show the monthly payment, APR, total interest, and cash-to-close under each option before deciding.

PMI and the Loan Estimate

PMI should be reviewed as part of your Loan Estimate. This document helps you see whether the monthly payment and closing costs match what you expected.

The CFPB explains that a Loan Estimate tells you important details about a mortgage loan you requested and can help you compare offers from different lenders. Review the CFPB Loan Estimate explainer.

When comparing loan offers, make sure you compare the same down payment, loan amount, rate type, points, lender credits, PMI structure, and loan term. A lower payment may not mean a better loan if PMI or interest costs differ.

Loan-to-Value Ratio and PMI

Loan-to-value ratio, or LTV, compares the mortgage loan amount with the home’s value or purchase price, depending on the loan context. A higher LTV usually means the borrower has less equity.

For example, if the home price is $400,000 and the mortgage is $360,000, the LTV is 90%. That means the buyer has 10% equity before accounting for closing costs and future value changes.

PMI is closely connected to LTV because PMI often applies when the borrower has less than 20% equity on a conventional mortgage.

How to Avoid PMI

The most direct way to avoid PMI on a conventional mortgage is to make a large enough down payment so the loan does not require it. For many conventional loans, that means reaching 20% down.

Other strategies may include choosing a lower-priced home, saving longer, using eligible down payment assistance, comparing loan programs, or considering lender-paid PMI only after comparing the long-term rate tradeoff.

The goal is not always to avoid PMI at all costs. Sometimes paying PMI for a period of time may be reasonable if it lets you buy a home sooner while keeping emergency savings intact. The key is to compare the numbers.

Ways to Reduce PMI Pressure

Even when avoiding PMI is not realistic, you may be able to reduce its impact.

• Increase your down payment if it does not drain emergency savings.
• Choose a lower home price.
• Improve credit before applying.
• Compare lenders and PMI structures.
• Ask about monthly, upfront, split-premium, and lender-paid options.
• Compare conventional and FHA loan costs carefully.
• Plan for PMI removal once eligible.
• Use extra principal payments carefully if they help you reach cancellation thresholds sooner.

When Can PMI Be Removed?

PMI is not always permanent. For many conventional mortgages, borrowers have rights to request removal once they reach a specified point, and PMI may also terminate automatically under certain conditions.

The CFPB explains that homeowners have the right to remove PMI for many mortgages once the mortgage has been paid down to a specified point, and that ending PMI reduces monthly costs. Review the CFPB PMI removal explanation.

The CFPB also notes that legal requirements described in its PMI removal resource apply to mortgages for single-family principal residences that closed on or after July 29, 1999. Always check your loan documents and ask your servicer how your specific loan handles PMI cancellation.

Borrower-Requested PMI Cancellation

Borrower-requested PMI cancellation usually means you ask your servicer to remove PMI once the loan balance reaches a certain threshold and other requirements are met.

Under many PMI cancellation rules, you may need to be current on payments, submit a written request, have a good payment history, and meet property value or lien requirements. Some servicers may require a property valuation before removing PMI based on current value.

Fannie Mae’s servicing guidance includes detailed requirements for conventional mortgage insurance termination, including borrower-initiated requests and automatic termination rules. Review Fannie Mae’s mortgage insurance termination guidance.

Automatic PMI Termination

Automatic PMI termination means the servicer is required to terminate PMI once the loan reaches a qualifying point under applicable rules, assuming requirements are met.

The CFPB’s Homeowners Protection Act examination procedures explain that the Act establishes provisions for canceling and terminating PMI, sets disclosure and notification requirements, and requires the return of unearned premiums. Review the CFPB Homeowners Protection Act overview.

Do not assume PMI will disappear from your payment without tracking it. Review your amortization schedule, payment history, home value, and servicer requirements.

PMI and Refinancing

Refinancing may remove PMI in some situations, especially if the home value has increased or the loan balance has dropped enough to create sufficient equity. But refinancing also has costs, and it may reset the loan term.

A refinance can be helpful if removing PMI, lowering the rate, or improving the loan structure creates enough savings to justify the closing costs. But it may not make sense if the break-even point is too long or the new loan increases total cost.

PMI and Escrow

PMI may be part of your monthly mortgage payment along with principal, interest, taxes, homeowners insurance, and escrow. Escrow is separate from PMI, but both can affect the monthly amount due.

If your payment changes after PMI is removed, review your mortgage statement carefully. Your escrow payment may still change later because of tax or insurance adjustments.

For escrow basics, read Escrow Accounts Explained.

Should You Wait to Avoid PMI?

Waiting to avoid PMI can make sense if you can save quickly, home prices are stable, and waiting does not create other costs. But waiting is not automatically better.

Consider these tradeoffs:

• How long will it take to reach 20% down?
• Will rent costs continue during that period?
• Could home prices or rates change while you wait?
• Would buying sooner leave enough emergency savings?
• How much would PMI cost each month?
• When could PMI be removed?
• Would a smaller home or lower price reduce the need for PMI?

The answer depends on your local market, savings rate, income stability, and comfort level with the monthly payment.

• Forgetting to track loan-to-value ratio over time.
• Refinancing only to remove PMI without checking closing costs.
• Assuming lender-paid PMI is free.
• Failing to review the Loan Estimate and Closing Disclosure carefully.

Frequently Asked Questions

What is PMI?

PMI stands for private mortgage insurance. It is insurance that protects the lender if a borrower stops making payments on a conventional mortgage.

Who does PMI protect?

PMI protects the lender, not the borrower. It may still help the borrower qualify with a smaller down payment, but the insurance benefit is for the lender.

When is PMI usually required?

PMI is commonly required on conventional loans when the down payment is less than 20%. It may also apply when refinancing if equity is below 20%.

How much does PMI cost?

PMI cost varies based on factors such as loan amount, down payment, loan-to-value ratio, credit profile, loan type, and PMI structure. Ask your lender for the exact premium.

Can PMI be removed?

PMI can often be removed on many conventional mortgages once the loan has been paid down to a specified point and other requirements are met. Ask your servicer for the rules that apply to your loan.

Is PMI the same as FHA mortgage insurance?

No. PMI is generally tied to conventional mortgages. FHA loans have FHA mortgage insurance rules, which can work differently and may be harder to remove.

Should I avoid PMI at all costs?

Not always. Avoiding PMI can save money, but waiting to buy or draining savings may not be the best choice. Compare PMI cost, emergency savings, rent, home prices, rates, and your timeline.

What should I do first?

Start with the Mortgage Calculator, estimate your payment with PMI, and compare it with a larger-down-payment option.

Conclusion

Private mortgage insurance can make it possible to buy a home with less than 20% down, but it also adds cost to the monthly mortgage payment. PMI is not automatically bad, but it should be understood before choosing a loan. Compare the monthly payment, down payment, cash reserves, PMI removal rules, and long-term affordability before deciding whether to buy now or wait. The smartest PMI decision is the one that balances homeownership timing with a payment you can afford and enough savings left after closing.
