PMI Removal Calculator
Find out when your loan-to-value ratio will drop below 80% (or 78% for automatic cancellation) so you can stop paying private mortgage insurance. Use this to plan a timeline or decide whether to make a lump-sum payment to accelerate PMI removal.
About this calculator
Private mortgage insurance (PMI) is required by lenders when a borrower's loan-to-value (LTV) ratio exceeds 80%. LTV = Current Loan Balance ÷ Home Value. Under the Homeowners Protection Act, PMI is automatically cancelled when LTV reaches 78% of the original home value, and borrowers can request cancellation at 80% LTV. Home appreciation raises the home value, lowering LTV even without extra payments. The target balance for removal is: TargetBalance = threshold × futureHomeValue, where futureHomeValue = homeValue × (1 + appreciationRate / 100). The number of months until the balance naturally amortizes to that target is estimated using: months = ln(TargetBalance / currentBalance) / ln(1 + monthlyRate). Note: this simplified calculation assumes purely amortization-driven balance reduction without tracking the full amortization schedule, so actual results may differ slightly.
How to use
Example: Home value $350,000, current balance $290,000, interest rate 6.5%, appreciation rate 3%, automatic PMI removal (78% threshold). FutureHomeValue = $350,000 × 1.03 = $360,500. TargetBalance = 0.78 × $360,500 = $281,190. Since $281,190 < $290,000, the balance needs to decline. MonthlyRate = 0.065 / 12 = 0.005417. Months = ln($281,190 / $290,000) / ln(1.005417) = ln(0.9697) / 0.005402 ≈ −0.03075 / 0.005402 ≈ 5.7 months, rounded up to 6 months until automatic PMI cancellation.
Frequently asked questions
How can I remove PMI from my mortgage faster than the scheduled date?
The fastest way to remove PMI is to make a lump-sum payment directly to your principal, reducing your loan balance below 80% of the home's current appraised value. You can then request a new appraisal and ask your lender to cancel PMI. Home improvements or a rising housing market may have increased your property value, which also lowers your LTV ratio — making an appraisal worthwhile even without extra payments. Some borrowers refinance specifically to eliminate PMI when their equity has grown, though you should run a break-even analysis to ensure refinancing costs are recovered.
What is the difference between automatic PMI cancellation and requesting early PMI removal?
Under the Homeowners Protection Act, automatic PMI cancellation occurs when your loan balance reaches 78% of the original purchase price, as long as you are current on payments — no action is required from you. You can request earlier cancellation when your balance drops to 80% of the original value, but the lender may require a current appraisal and a good payment history. The key distinction is that automatic cancellation uses the original home value, while early removal requests may allow you to use current (appreciated) market value, potentially enabling cancellation much sooner. Contact your servicer directly to understand their specific requirements.
How much money can I save by removing PMI earlier on my mortgage?
PMI typically costs between 0.2% and 1.5% of the original loan amount per year, or roughly $80–$200 per month on a $200,000 loan. Over several years, this adds up to thousands of dollars in non-equity-building expenses. For example, paying $150/month in PMI for 36 extra months costs $5,400. Making a strategic lump-sum principal payment to eliminate PMI sooner can provide an immediate, guaranteed return equivalent to that monthly savings rate. Because PMI protects the lender rather than the borrower, eliminating it as early as possible is almost always financially advantageous.
