Private mortgage insurance is one of the most misunderstood costs in home buying — buyers often learn about it for the first time at their mortgage application, where it suddenly adds $150–$375 to a monthly payment they had already budgeted carefully. PMI is not optional when you put less than 20% down on a conventional loan, and it is not a benefit to the buyer — it protects the lender against default risk while costing the buyer real money every month. But it is eliminatable — and understanding exactly when and how to remove it is the knowledge that can save thousands of dollars annually.
Quick Answer: PMI (private mortgage insurance) is a monthly premium added to your mortgage payment when your down payment is less than 20% on a conventional loan. It costs approximately 0.46%–1.5% of the original loan amount annually — about $115–$375/month on a $300,000 loan. PMI protects the lender, not you. It can be cancelled when your loan-to-value ratio (LTV) reaches 80% through principal paydown, property appreciation, or both. Under federal law (the Homeowners Protection Act), it must be automatically terminated at 78% LTV based on the original amortisation schedule.
From a monthly cash flow perspective, PMI is a fixed monthly cost that adds directly to the burden of homeownership without building equity or providing any benefit to the buyer. The faster it is eliminated, the faster that monthly cash is freed for debt paydown, investment, or savings. Every buyer who puts less than 20% down on a conventional loan should have a specific plan for reaching 20% equity and triggering PMI cancellation — not a vague intention to "get rid of it eventually." This connects to the down payment analysis in how much down payment you really need and the full home buying guide at how to buy your first home.
What is PMI and why do lenders require it?
Private mortgage insurance (PMI) is an insurance policy that the borrower pays for, which protects the mortgage lender in the event of default. When a borrower puts less than 20% down on a home purchase, the lender carries higher risk — the lower the down payment, the less equity the borrower has as a buffer against default. PMI compensates the lender for this additional risk. According to the Urban Institute, PMI allows buyers to access mortgage financing with as little as 3–5% down — without it, most lenders would require 20% down for all conventional loans, pricing millions of buyers out of homeownership. PMI is distinct from FHA mortgage insurance premiums (MIP), which apply to FHA loans and are structured differently.
How much does PMI cost?
PMI costs vary based on loan amount, down payment percentage, credit score, and loan type. According to the Urban Institute, typical PMI costs range from 0.46% to 1.5% of the original loan amount annually. The rate is highest for borrowers with lower credit scores and smaller down payments, and lower for borrowers with higher scores and down payments closer to 20%.
| Original Loan Amount | PMI Rate (0.85%) | Annual Cost | Monthly Cost |
|---|---|---|---|
| $200,000 | 0.85% | $1,700 | $142 |
| $300,000 | 0.85% | $2,550 | $213 |
| $400,000 | 0.85% | $3,400 | $283 |
| $500,000 | 0.85% | $4,250 | $354 |
How to get rid of PMI — the three methods
Method 1 — Request cancellation at 20% equity
Under the Homeowners Protection Act (HPA), you have the right to request PMI cancellation when your loan balance reaches 80% of the home's original purchase price — meaning you have 20% equity. You must submit a written request to your servicer, be current on payments, and may be required to provide evidence of the home's current value (appraisal at your expense, typically $300–$600). The servicer must cancel PMI within 30 days of confirming the 80% LTV threshold has been reached.
Method 2 — Automatic termination at 78% LTV
The HPA requires servicers to automatically cancel PMI when the loan balance reaches 78% of the original purchase price based on the scheduled amortisation — no request required. This happens on a specific date calculated from your original loan schedule. Note: this is based on the original purchase price, not current market value, so appreciation alone does not trigger automatic termination. The termination date is typically shown in your original closing documents.
Method 3 — Refinance out of the PMI loan
If home appreciation has pushed your LTV below 80% but your servicer requires an appraisal you have not ordered, or if you have an FHA loan (where MIP applies for the full loan life on loans with less than 10% down), refinancing to a conventional loan with 20%+ equity eliminates PMI entirely. Refinancing has upfront costs (2–5% of loan amount in closing costs) but can make sense when it also secures a lower interest rate simultaneously.
Accelerated equity building to eliminate PMI faster. Extra principal payments directly reduce your loan balance — accelerating the date you reach 20% equity. On a $350,000 loan with 10% down: standard amortisation reaches 80% LTV in approximately 8–9 years. Making $200/month in extra principal payments reaches 80% LTV in approximately 5–6 years — saving approximately 3 years of PMI at $250/month = $9,000. The full strategy is covered in how to pay off your mortgage faster.
PMI vs FHA mortgage insurance — key differences
FHA mortgage insurance premiums (MIP) are structurally different from conventional PMI. FHA MIP includes an upfront premium of 1.75% of the loan amount paid at closing (or rolled into the loan), plus an annual premium of approximately 0.55%–0.75% of the outstanding balance paid monthly. For FHA loans with less than 10% down payment, MIP applies for the full life of the loan — it cannot be cancelled regardless of equity level. This is why financial advisors often recommend transitioning from an FHA loan to a conventional loan once sufficient equity has been built — the refinance eliminates the permanent MIP in exchange for a one-time refinancing cost.
Conclusion
PMI is a real monthly cost that adds to the burden of homeownership — but it is a temporary and eliminatable cost for conventional loan borrowers. Every buyer putting less than 20% down should enter the purchase with a clear equity-building plan: know your current LTV, know the monthly paydown rate, factor in your market's appreciation trend, and calculate the approximate date your equity reaches 20%. Then set a calendar reminder to request PMI cancellation at that date. The goal is to pay PMI for the minimum time necessary — not indefinitely.

Key Takeaways
- PMI (private mortgage insurance) is required on conventional loans when the down payment is less than 20%. It costs approximately 0.46–1.5% of the original loan amount annually — roughly $142–$354/month on a $300,000–$500,000 loan. It protects the lender, not the buyer.
- PMI can be cancelled when the loan-to-value ratio reaches 80% (20% equity) by written request to the servicer. Evidence of current home value via appraisal may be required at your expense ($300–$600).
- Under the Homeowners Protection Act, servicers must automatically terminate PMI at 78% LTV based on the original amortisation schedule — no request required, but you must be current on payments.
- FHA mortgage insurance premiums (MIP) are different from PMI: FHA MIP applies for the full loan life on loans with less than 10% down and cannot be cancelled — requiring a refinance to a conventional loan to eliminate it once sufficient equity is reached.
- Making extra principal payments accelerates equity building and brings the 20% threshold forward significantly. On a $350,000 loan, $200/month extra saves approximately $9,000 in PMI by reaching 80% LTV 3 years sooner.
- Refinancing out of an FHA loan to a conventional loan once equity exceeds 20% eliminates the permanent MIP — the refinancing cost is typically recovered in PMI savings within 2–3 years.
Frequently Asked Questions
PMI (private mortgage insurance) is a monthly premium added to your mortgage payment when you put less than 20% down on a conventional loan purchase. It insures the lender — not the buyer — against the risk of default. The cost typically ranges from 0.46% to 1.5% of the original loan amount annually, which means approximately $115–$375 per month added to the mortgage payment on a $300,000 loan. PMI is separate from homeowner's insurance (which protects the buyer's property) and is a lender-required cost that cannot be avoided with less than 20% down on a conventional loan.
There are three ways to eliminate PMI: (1) Request cancellation when your loan balance reaches 80% of the original purchase price — submit a written request to your loan servicer with evidence of current value if required. (2) Wait for automatic termination at 78% LTV based on the scheduled amortisation — no request needed. (3) Refinance the loan once you have 20%+ equity — eliminates PMI but incurs new closing costs. For FHA loans (MIP, not PMI), the only path to elimination for loans with less than 10% down is refinancing to a conventional loan once equity reaches 20%.
PMI typically costs 0.46%–1.5% of the original loan amount annually. On a $300,000 loan at a 0.85% PMI rate, the annual cost is $2,550 — approximately $213/month. On a $400,000 loan: approximately $283/month. On a $500,000 loan: approximately $354/month. Your exact PMI rate depends on your credit score (higher score = lower PMI rate), loan-to-value ratio (closer to 80% = lower rate), and loan type. The rate is set at origination and does not change as you pay down the balance — it is calculated as a percentage of the original loan amount, not the current balance.
PMI deductibility has varied significantly based on US tax legislation. The PMI tax deduction was available for qualifying taxpayers in various years, eliminated, then reinstated retroactively multiple times by Congress. As of the most recent legislative session, the deductibility of PMI for itemising taxpayers is subject to current tax law — check with a qualified tax professional or the IRS website for the current status in the tax year you are filing. Even when available, the deduction is subject to income phase-outs for higher earners and only applies if you itemise rather than taking the standard deduction.
In many market situations, yes — paying PMI to buy sooner is financially superior to waiting years to save a 20% down payment. The comparison: PMI at $250/month for 3 years totals $9,000 in PMI costs. But if waiting 3 more years to save 20% down means paying $2,000/month in rent during that period, the opportunity cost of waiting is $72,000 in rent — far more than the PMI cost. Additionally, 3 years of home price appreciation and principal paydown can build significant equity that renting forfeits entirely. In markets with flat or declining prices, the calculation shifts — PMI may cost less than appreciation benefits justify. Run the numbers for your specific market, rent level, and savings capacity before deciding.
