PMI: What It Costs and How to Remove It

What PMI Is (and Isn't)

Private mortgage insurance protects the lender - not you - if you default. It is required on most conventional loans when your down payment is under 20%. Think of it as the price of buying sooner with less saved: it does nothing for you directly, but it unlocks the purchase.

PMI typically costs 0.5% to 1.5% of the loan amount per year, billed monthly. On a $400,000 loan at 1% that is $4,000 per year - about $333 per month - on top of your principal, interest, taxes, and insurance. Over several years, that adds up to tens of thousands of dollars.

What PMI Actually Costs in Dollars

Freddie Mac estimates private mortgage insurance runs about $30 to $70 a month for every $100,000 borrowed. On a $360,000 loan that is roughly $108 to $252 a month, or $1,300 to $3,000 a year. Where you land in that range depends mostly on two things: your credit score and your loan-to-value ratio.

Credit matters enormously. A borrower with a 760 score putting 10% down might pay around 0.3% a year, while a borrower with a 660 score at 5% down can pay 1.5% or more. The loan term matters too: 15-year loans carry lower PMI rates than 30-year loans because the lender's risk window is shorter.

One useful way to think about PMI: it is the most expensive debt you will ever voluntarily carry, because it buys you nothing. Every month you pay it past the point where you could have removed it is money with zero return. That framing tends to focus the mind on the removal strategies below.

One more cost driver people miss: loan term. A 15-year mortgage carries lower PMI rates than a 30-year loan at the same LTV, because the insurer's risk window is half as long. And single-premium PMI, where you pay the whole premium upfront at closing (often 1-2% of the loan), can be cheaper than monthly PMI if you keep the loan past the breakeven point, usually 5-7 years. Ask your lender to quote both structures before you choose.

The 10-Year Trap: A Full Worked Example

Take a $400,000 home bought with 10% down: a $360,000 loan at 7.40% over 30 years. The monthly principal and interest payment is about $2,493. Add PMI of around $200 a month (mid-range for decent credit), and the true monthly cost is roughly $2,693 before taxes and insurance.

Automatic termination kicks in when the balance is scheduled to reach 78% of the original $400,000 value, which is $312,000. On the original amortisation schedule at 7.40%, that happens around payment 120, about 10 years in. If you never request early cancellation, you pay roughly $200 × 120 = $24,000 in PMI before it drops off on its own.

Now the alternative: request cancellation at 80% LTV ($320,000 balance), which the schedule hits about a year earlier, or use appreciation. If the home rises 12.5% to $450,000, your $360,000 balance is suddenly at 80% of current value and you can request removal almost immediately with a $400 appraisal. The $24,000 figure is what passivity costs; attention is free.

The Automatic Drop-Off at 78% LTV

Here is the part many homeowners miss: on a primary residence with a conventional loan, your servicer must automatically cancel PMI when your loan balance falls to 78% of the original purchase price - based on the original amortisation schedule. You do not need to ask; it is federal law (the Homeowners Protection Act).

Note the catch: it is 78% of the original value on the original schedule. Extra payments that get you there faster do not trigger automatic cancellation early - but they do qualify you to request cancellation sooner, which brings us to the 80% rule.

Requesting Cancellation at 80% LTV

You can request PMI cancellation once your balance reaches 80% of the original value - but you must ask, be current on payments, and often pay for a new appraisal or broker price opinion ($300-$500) to prove the value. If your home has appreciated, appreciation counts: a $400,000 purchase now worth $480,000 with a $380,000 balance is at 79% LTV against current value.

The maths usually favours acting: spending $400 on an appraisal to kill a $250/month PMI payment pays for itself in under two months. Call your servicer first and ask for their exact process - requirements vary.

FHA MIP: The Other Mortgage Insurance

FHA loans carry their own insurance, called MIP, with harsher rules. You pay an upfront premium of 1.75% of the loan amount (usually financed into the loan: $6,300 on a $360,000 base loan) plus an annual premium, currently 0.55% for most 30-year loans with less than 5% down, billed monthly. On $360,000 that is about $165 a month.

The critical difference: with less than 10% down, FHA annual MIP lasts for the life of the loan. It never drops off automatically. Put down 10% or more and it ends after 11 years. For the typical FHA buyer putting 3.5% down, the only exits are selling or refinancing into a conventional loan.

This makes the FHA-to-conventional refinance one of the highest-value moves in American home finance. Once your home has appreciated enough (or you have paid down enough) to reach 80% LTV on a conventional refinance, the MIP disappears entirely. Run that comparison the moment your equity crosses 20%.

PMI Avoidance Strategies That Actually Work

The cleanest avoidance is 20% down, but that is not advice, it is arithmetic. More interesting are the structural alternatives. A piggyback loan (80-10-10): an 80% first mortgage, a 10% second mortgage, and 10% down. No PMI because the first mortgage is at 80% LTV, but you pay a higher rate on the second loan. It wins when the second loan's rate is reasonable and you plan to pay it off aggressively.

Lender-paid PMI is the quieter option: the lender pays the insurance and charges you a slightly higher rate instead, typically 0.25% to 0.5% more. It can be cheaper than borrower-paid PMI for buyers who will sell or refinance within a few years, but the higher rate lasts for the life of the loan while borrower-paid PMI can be cancelled. Do the breakeven before choosing.

The appreciation play deserves its own mention. In rising markets, many buyers reach 80% LTV through price growth years before the amortisation schedule gets them there. Ordering an appraisal the moment you plausibly cross the line is the single highest-ROI phone call in homeownership: $400 to save $200+ a month.

Faster Routes: Appreciation, Improvements, Refinancing

In rising markets, appreciation alone can erase PMI years ahead of schedule. Home improvements that genuinely raise appraised value work the same way. And if rates have fallen since you bought, refinancing into a new loan at 80% LTV or below removes PMI by definition - though you should weigh closing costs against the PMI savings.

One warning: FHA loans work differently. FHA mortgage insurance premium (MIP) typically lasts for the life of the loan if your down payment was under 10% - refinancing into a conventional loan is usually the only exit. Know which type you have before planning.
