What is Private Mortgage Insurance (PMI)?
Private mortgage insurance (PMI) is insurance that protects the lender — not the borrower — against loss if the borrower defaults on the mortgage. It is required on conventional loans when the down payment is less than 20% of the purchase price. PMI is typically paid as a monthly premium added to the mortgage payment, though it can also be paid upfront or through a higher interest rate. Once the borrower builds 20% equity, PMI can be canceled.
Step-by-Step Guide
Determine Your PMI Rate
PMI rates range from 0.5% to 1.5% of the loan amount annually. Your rate depends on your credit score, down payment percentage, loan amount, and loan type. Request a PMI rate quote from your lender or use industry rate tables. Higher credit scores and larger down payments result in lower rates — for example, a 760+ credit score with 10% down might pay 0.3%, while a 640 score with 3% down could pay 1.5%.
Calculate Your Monthly PMI Payment
Multiply your loan amount by the annual PMI rate, then divide by 12 for the monthly cost. For example, a $280,000 loan with a 0.8% PMI rate costs $2,240 per year or approximately $187 per month. Add this to your principal, interest, taxes, and insurance (PITI) to calculate your total monthly housing payment.
Determine Your PMI Removal Date
Using your amortization schedule, find the date when your loan balance will reach 80% of the original purchase price — this is when you can request PMI cancellation. Also note the date it reaches 78%, when automatic cancellation is required by federal law. Factor in any extra principal payments that could accelerate this timeline.
Calculate the Total Cost of PMI
Multiply your monthly PMI payment by the number of months you will pay it (from loan origination to removal date). This gives you the total lifetime cost of PMI. Compare this against the cost of a larger down payment to determine which approach saves more. Also compare against lender-paid PMI options where the cost is built into a higher interest rate.
Explore Early Removal Strategies
Calculate the impact of extra principal payments on your PMI removal timeline. Determine if home appreciation could support early removal through a new appraisal. Evaluate whether refinancing at a lower LTV makes sense. Create an actionable plan with specific milestones to eliminate PMI as quickly as possible.
Best Practices
PMI can be paid monthly, as a single upfront premium, or through lender-paid PMI with a higher interest rate. Each option has different total costs depending on how long you keep the loan. Monthly PMI is best if you plan to refinance or remove PMI soon; upfront PMI may save money if you plan to stay long-term.
PMI rates are heavily influenced by credit scores. Improving your score from 680 to 740 before applying could reduce your PMI rate by 0.3-0.5%, saving $50-$100+ per month. This is one of the highest-impact financial improvements you can make before buying a home.
If your home appreciates significantly, you may qualify for PMI removal sooner than your amortization schedule suggests. Track local home values and request a new appraisal from your lender if you believe your equity has reached 20%. Some lenders accept broker price opinions instead of full appraisals.
Even small additional principal payments accelerate equity building and advance your PMI removal date. Directing a few hundred dollars per month to principal can shave months or years off your PMI obligation. Calculate the impact before committing to see exactly how much you will save.
Common Mistakes to Avoid
Not Requesting PMI Removal at 80% LTV: Mark your calendar for when your LTV reaches 80% based on your amortization schedule and submit a written cancellation request to your lender immediately. You must be current on payments and may need a satisfactory payment history.
Choosing FHA Over Conventional Without Comparing PMI Costs: Get quotes for both FHA and conventional loans and compare the total mortgage insurance cost over the expected loan life. Factor in the FHA upfront premium and the inability to cancel FHA MIP without refinancing.
Ignoring PMI When Calculating Affordability: Always include PMI in your total monthly housing cost calculation. Ask your lender for PMI rate quotes at different down payment levels so you can make an informed decision about how much to put down.
Paying for a Larger Down Payment When PMI Is Cheaper: Calculate the total PMI cost over your expected payment period and compare it against the returns you could earn by investing the difference. If PMI costs $5,000 total but keeping $40,000 invested earns $8,000, the PMI route wins financially.

Frequently Asked Questions
You pay PMI until your loan-to-value ratio reaches 80% (when you can request cancellation) or 78% (when automatic cancellation is required). The timeline depends on your loan terms and any extra payments you make. For a 30-year loan with 5% down, this typically takes 7-11 years without extra payments. Home appreciation can shorten this timeline.
No, PMI protects the lender against loss if you default on your mortgage. It does not provide you with any insurance benefit. Despite paying for it, you receive no coverage or protection. This is why removing PMI as soon as possible is in your financial interest.
Yes, piggyback loans (80/10/10 or 80/15/5) use a second mortgage to avoid PMI by keeping the first mortgage at or below 80% LTV. However, the second mortgage typically carries a higher interest rate. Compare the total cost of a piggyback structure against PMI to determine which is cheaper for your situation and timeline.
No, they are completely different. PMI protects the lender if you default on your mortgage. Homeowners insurance protects you against property damage and liability. Homeowners insurance is required by lenders regardless of your down payment amount and is a separate expense from PMI.
FHA loans charge mortgage insurance premium (MIP) instead of PMI. FHA MIP includes an upfront premium of 1.75% of the loan amount (usually financed into the loan) plus annual premiums of 0.55-1.05% depending on loan terms. Unlike conventional PMI, FHA MIP cannot be canceled on loans with less than 10% down — it lasts the life of the loan. To remove it, you must refinance into a conventional loan.
