PMI Removal: How Extra Principal Payments Kill PMI Faster
Example: Original purchase price: 380000 $ · Original loan amount: 361000 $ · Mortgage interest rate: 6.75 %/yr · Loan term: 30 yrs · PMI annual rate: 0.75 %/yr · Extra monthly principal payment: 200 $ · Annual home appreciation (for equity estimate): 3 %/yr
| Total PMI saved by extra payments | $9,702 |
| Monthly PMI cost | $226 |
| PMI paid without extra payments | $31,362 |
| PMI paid with extra payments | $21,660 |
| Months of PMI eliminated | 43 |
Worked example
On a $380,000 home with $361,000 financed (5% down) at 6.75%, PMI at 0.75% costs $226/month. Without extra payments, PMI runs for about 126 months (10.5 years), totaling $28,476. Adding $200/month extra reduces PMI to 85 months — saving 41 months and $9,266 in PMI premiums. The $200 extra costs you $17,000 over those 85 months, but the combined interest + PMI savings more than pay for it.
Frequently asked questions
When does PMI automatically cancel?
Under the Homeowners Protection Act, lenders must automatically cancel PMI when your loan balance reaches 78% of the original purchase price based on the amortization schedule — even if you do nothing. You can request cancellation at 80% LTV if you have a good payment history and can document value through an appraisal.
Can I use appreciation to remove PMI sooner?
Yes. If your home has appreciated and your current balance is below 80% of current appraised value (not original purchase price), you can request PMI removal with a new appraisal. Lenders typically require at least 2 years of ownership and a clean payment history. This path is separate from the 78% automatic cancellation.
Is extra principal always better than just requesting PMI removal via appreciation?
Not necessarily. In a fast-appreciating market, a single appraisal (typically $300–$600) may remove PMI years sooner than extra payments alone. The best strategy combines both: track your loan balance AND your home value, and use whichever path reaches 80% LTV first.
