How to use the PMI Calculator

Enter home value, down payment, mortgage rate and term, plus an estimated annual PMI premium rate. Choose an 80% or 78% LTV modeling threshold to estimate how long that entered premium would remain in the schedule.

PMI rules are not just an LTV formula

For many conventional mortgages, federal rules distinguish borrower-requested cancellation around 80% of original value from scheduled automatic termination around 78%, with conditions and exceptions. Actual premium pricing and cancellation are controlled by your loan, servicer, insurer, payment status, property-value rules, and applicable law.
