PMI Removal Calculator
This calculator works out when private mortgage insurance comes off a conventional loan. Enter the loan amount, rate, term and the value the lender used at closing, and it returns the payment number at which the schedule reaches 80% of that original value, the 78% point where the servicer must end the insurance without being asked, and the midpoint of the term where it ends regardless. Add the monthly premium, any extra principal, the payments made so far or a current appraisal, and it shows what each of those changes and what it does not. The three dates come from the Homeowners Protection Act, which fixes them to the original value, so a higher appraisal never moves them.
