PMI is calculated as an annual percentage of your original loan amount, divided by 12 for the monthly cost. Rates typically range from 0.5% to 1.5% annually depending on your credit score, loan type, and LTV ratio. This calculator uses your entered rate (defaulting to 0.85% as a typical mid-range estimate).
PMI removal is calculated by running the full amortization schedule and finding the month when your loan balance reaches 80% of the original home value. Under the Homeowners Protection Act (HPA), you can request cancellation at 80% LTV and lenders must automatically cancel at 78% LTV based on the original amortization schedule. This calculator shows the 80% threshold, the earliest you can request removal.
