The formulas
- Balance after k payments = L x (1 + r)^k - P x ((1 + r)^k - 1) / r
- Cancellation request: first k with balance <= 80% of original value
- Automatic termination: first k with balance <= 78% of original value
How it works
The Homeowners Protection Act sets two dates for private mortgage insurance on a fixed-rate home loan. A borrower may ask to cancel once the principal balance is first scheduled to reach 80 percent of the original value of the property, or actually reaches 80 percent from payments. The insurance ends automatically when the balance is scheduled to reach 78 percent, if the borrower is current.
There is also a backstop: if neither date has ended it, the requirement cannot continue past the first day of the month after the midpoint of the amortization period. Cancellation on request also needs a good payment history and the lender may require proof that value has not declined and no junior lien. Original value is the lesser of the contract price and the appraised value at closing for a purchase; the Act covers single-family primary residences with loans closed after July 29, 1999.

Common questions
Can I cancel earlier by paying extra?
Yes. Based on actual payments the balance can reach 80 percent sooner, and you may request cancellation then.
What if I am late on payments?
Automatic termination waits until you are current, and a request needs a good payment history.
Does appreciation count?
The statute measures against the original value of the property, so appreciation does not move these dates.
