PMI Removal: The Month You Can Ask, and What $300 Extra Buys
2026-09-18
Short answer: By federal rule you may request PMI cancellation once the balance reaches 80% of the original value, and the servicer must terminate it automatically at 78%. On a $360,000 loan at 6.95% that point arrives at month 100 on the scheduled payments. Adding $300 a month reaches it at month 57, cutting 43 months of PMI — $6,450 at $150 a month.
The two dates
Federal rules give a borrower two separate points on a qualifying loan with borrower-paid private mortgage insurance:
- 80% of the original value — you may request cancellation, in writing. Conditional on a good payment history and the servicer’s requirements.
- 78% of the original value — the servicer must terminate it automatically, provided you are current on payments.
Both are measured against the original value, not today’s. The difference between requesting at 80% and waiting for 78% is several months of premiums, paid for no reason other than not having asked.
The arithmetic
months to target = ln((M ÷ r − target) ÷ (M ÷ r − principal)) ÷ ln(1 + r)Worked example — a 400,000 home, 360,000 loan at 6.95% over 30 years, PMI at 150 a month. The 80% threshold is a balance of 320,000.
| Scenario | Month 80% is reached | PMI paid |
|---|---|---|
| Scheduled payments ($2,383.01) | month 100 | $15,000 |
Plus 300 a month (2,683.01) | month 57 | $8,550 |
| Saving | 43 months | $6,450 |
The extra $300 a month does two things at once: it removes 43 months of PMI, and every dollar of it also earns the loan’s 6.95% by reducing the balance. The PMI saving alone is a return on top of that.
Why the early years are so slow
At month 1, a 2,383.01 payment on a 6.95% loan puts about 2,085 toward interest and only 298 toward principal. Reaching 40,000 of principal reduction at that rate takes years, which is why the schedule says month 100.
Extra payments go entirely to principal, so their effect on the PMI date is far larger than their size suggests. $300 a month is 12.6% more payment and it removes 43% of the PMI period.
The checklist for actually getting it removed
- Confirm the kind of insurance you have. Borrower-paid PMI can be cancelled. Lender-paid mortgage insurance is inside the rate and cannot. FHA insurance follows its own rules and frequently lasts the life of the loan.
- Work out your 80% balance — 80% of the original value, not the current one.
- Diarise the month, from your amortisation schedule plus any extra payments you have made.
- Request in writing when you reach it. Do not wait for automatic termination at 78%.
- Ask what the servicer requires — typically a good payment record, no junior liens, and sometimes an appraisal at your cost.
What would reverse the conclusion
- An appreciation-based cancellation. If local values have risen sharply, a current-value cancellation may arrive far earlier than the schedule. It is discretionary and usually needs a paid appraisal, so weigh the appraisal fee against the remaining premiums.
- A refinance you were doing anyway. If the rate justifies a refinance on its own, PMI removal comes free with it. It is a bonus, not a reason.
- Money with a better use. The extra $300 earns the mortgage rate plus the PMI saving — a strong, guaranteed return, but not ahead of clearing a credit card at 24% or capturing an employer retirement match.
