PMI Removal Calculator With Home Appreciation
Home appreciation can push your loan-to-value ratio below 80 percent years before the standard amortization schedule would. Under the Homeowners Protection Act, you may request PMI cancellation at 80 percent LTV and the servicer must cancel it automatically at 78 percent. Enter your current balance, home value, and expected appreciation rate above to see when you cross each threshold.

Cancellation at 80% is a request you must make in writing and the servicer can require proof of value and a clean payment record. Termination at 78% is automatic. Both are set by the Homeowners Protection Act, cited below.
The Two PMI Removal Triggers
The Homeowners Protection Act creates two distinct paths. The borrower-initiated route lets you request cancellation once the principal balance reaches 80 percent of the original purchase price. You must be current on payments, have a good payment history, and the lender may require proof that no subordinate liens exist.
The automatic route kicks in at 78 percent of the original value with no request needed — the servicer is legally required to cancel PMI on that date, provided the loan is current. If you have missed payments that delayed reaching 78 percent, cancellation occurs the month after you become current.
A third, less-known path uses the current appraised value rather than the original price. If your home has appreciated significantly, you can request a new appraisal. If the resulting LTV is at or below 80 percent based on the new value, many lenders will cancel PMI early. Servicer policies on appraisal-based removal vary, so confirm the process and cost before ordering.
How Appreciation Accelerates the Timeline
Without appreciation, reaching 80 percent LTV depends entirely on principal payments — a slow process in the early years of a mortgage when most of each payment goes to interest. Appreciation works from the other side of the fraction: as the home value rises, the same balance represents a smaller percentage of value.
For example, a borrower who purchased a home for $400,000 with 10 percent down has a $360,000 loan and an initial LTV of 90 percent. Through payments alone, reaching 80 percent LTV might take several years. If the home appreciates at an illustrative 3 percent annually, the value rises to approximately $412,000 after one year. Combined with principal reduction, the appraisal-based LTV can fall below 80 percent far sooner than the amortization schedule predicts.
The calculator models both paths — scheduled paydown and appreciation — simultaneously. Use it alongside the PMI removal date calculator and the PMI cost estimator to see not just when PMI drops but how much you will save once it does.
Appreciation rates are not guaranteed. The calculator uses the rate you enter as a projection, not a prediction of future home values.
