PMI can disappear before the mortgage is paid off, but “20% equity” is not one universal rule. Federal cancellation rights commonly use the home's original value, while some investor rules allow earlier requests based on current value.
The PMI Removal Appraisal Break-Even Calculator compares both loan-to-value calculations and shows how long a quoted broker price opinion or appraisal cost would take to recover through avoided PMI.
The calculator does not determine eligibility. Reaching an LTV percentage does not establish that a servicer must cancel PMI. Payment history, seasoning, property type, liens, investor rules, and the valuation process can matter.
The quick answer
The Consumer Financial Protection Bureau (CFPB) says many covered borrowers can request PMI cancellation when the principal balance is scheduled to reach 80% of the home's original value. Extra principal payments can also move the actual balance to that 80% original-value level earlier.
Automatic termination generally works differently. CFPB says it normally occurs when the mortgage is scheduled to reach 78% of original value, assuming the borrower is current. Extra payments that reduce the actual balance do not move that scheduled automatic date forward.
Fannie Mae also has current-value cancellation paths for some conventional loans. Those rules can use a new property valuation and different loan-to-value ratio (LTV) thresholds depending on loan age and property type.
What original value means
CFPB says “original value” generally means the lower of the purchase price or appraised value when the home was purchased. If the mortgage has been refinanced, the relevant original value is generally the appraised value at the time of that refinance.
That definition matters because appreciation does not change the original-value calculation. A home that rose substantially in market value can still have an original-value LTV above 80%.
Use the Loan-to-Value Calculator when you want to explore LTV, combined loan-to-value ratio, and home equity separately from the PMI break-even question.
The 80% borrower-requested reference
CFPB says many borrowers have the right to request cancellation when the principal balance is scheduled to fall to 80% of original value. A borrower may also request earlier cancellation after extra payments reduce the actual balance to 80% of original value.
Meeting the balance test is not the only requirement. CFPB lists conditions that can include a written request, current payments, good payment history, no junior liens, and evidence that the property's value has not fallen below the original value when the servicer requires it.
Fannie Mae's servicing guidance likewise uses an 80% original-value LTV criterion for borrower-initiated termination on a one-unit principal residence or second home, along with payment-record and property-value requirements.
The 78% automatic-termination reference
The automatic rule is easy to misunderstand because the percentage is tied to the scheduled balance, not simply the balance shown on today's mortgage statement.
CFPB says PMI generally must terminate when the scheduled principal balance reaches 78% of original value and the borrower is current. If the borrower is not current at that point, termination occurs after the loan is brought current.
Making a large extra principal payment can help reach the 80% borrower-requested level sooner, but CFPB has specifically explained that extra payments do not advance the scheduled 78% automatic-termination date.
Using current value for an earlier request
Investor rules can be more favorable than the federal original-value minimums. Fannie Mae, for example, permits borrower-initiated mortgage-insurance termination based on current value when its requirements are met.
For a one-unit principal residence or second home, Fannie Mae's current servicing guidance uses:
- 75% or lower LTV when the mortgage has been outstanding between two and five years.
- 80% or lower LTV when the mortgage has been outstanding more than five years.
- A possible waiver of the normal two-year seasoning requirement when qualifying borrower improvements increased the property's value, with an 80% LTV threshold.
Fannie Mae has separate rules for investment properties and two- to four-unit principal residences. Other investors and servicers can have different requirements.
That is why the calculator lets you enter the current-value LTV threshold to test rather than assuming 80% applies to every loan.
Property valuation: broker price opinion vs. appraisal
A broker price opinion (BPO) is a property-value estimate prepared by a real-estate professional. An appraisal is a valuation performed by an appraiser under the applicable appraisal standards.
Fannie Mae's servicing procedure says a one-unit property's current value for mortgage-insurance termination may require an interior and exterior BPO or an appraisal when required. Two- to four-unit properties use an appraisal under that procedure.
The borrower can be responsible for the valuation cost. Fannie Mae publishes specific BPO and appraisal fees in its servicing procedure, but fee schedules can change. Enter the amount quoted by the servicer into the calculator instead of relying on a generic appraisal cost.
When paying for a valuation may make financial sense
The simplest break-even calculation is:
Valuation cost ÷ monthly PMI
Monthly PMI × months remaining − valuation cost
This is conditional math. It assumes the valuation supports the required value, the servicer approves the request, and PMI stops without another meaningful delay or cost.
If the valuation fee takes 18 months to recover and PMI is expected to disappear in 10 months anyway, paying for the valuation is difficult to justify on the savings alone. If break-even is four months and PMI would otherwise continue for several years, the economics can look very different.
A complete example
Consider these assumptions:
- Current mortgage balance: $300,000
- Monthly PMI: $125
- Original value: $350,000
- Estimated current value: $450,000
- Quoted valuation cost: $450
- Current-value LTV threshold being tested: 80%
- Expected PMI duration without the request: 24 months
The original-value LTV is about 85.7%, so reaching an 80% original-value balance would require about $20,000 of additional principal reduction.
Using the estimated current value, the LTV is about 66.7%. At an 80% threshold, a $300,000 balance would require a verified value of at least $375,000.
A $450 valuation cost divided by $125 of monthly PMI produces a simple break-even of about 3.6 months. If PMI would otherwise continue for 24 months, the conditional net savings are about $2,550.
The example shows the economics, not approval. If the applicable current-value rule requires different seasoning, payment history, property type, LTV, or valuation evidence, the servicer can reach a different eligibility result.
Pay down principal or pay for a valuation?
Sometimes the cheaper path is obvious. If the balance is only a few hundred dollars above the applicable original-value threshold, a small principal payment may cost less than a new valuation.
In other cases, appreciation can create enough current-value equity that paying for an accepted valuation may be far less expensive than reducing principal to the original-value threshold.
The calculator shows both principal-reduction amounts so you can compare the scale of the two paths before calling the servicer.
Government-backed and lender-paid mortgage insurance
This guide focuses on conventional borrower-paid PMI. CFPB says mortgages insured by the Federal Housing Administration (FHA) or guaranteed by the Department of Veterans Affairs (VA) follow different mortgage-insurance or funding-fee rules.
Lender-paid mortgage insurance also works differently because the insurance cost is not billed to the borrower as a separate monthly PMI charge in the same way.
If the monthly mortgage statement uses mortgage insurance premium rather than PMI, or the loan is FHA, VA, or another government program, ask the servicer which cancellation rules apply before using this calculator to make a decision.
Questions to ask the servicer
- Is this conventional borrower-paid PMI?
- Who owns or guarantees the loan?
- Can I request cancellation using original value now?
- Is a current-value cancellation path available?
- What LTV threshold and seasoning requirement apply?
- What type of valuation is required and what will it cost?
- Does the servicer order the valuation, or may I choose the appraiser?
- Are there payment-history or junior-lien requirements?
- When is PMI scheduled to terminate if I do nothing?
