It estimates your monthly private mortgage insurance cost on a conventional loan and shows when you can expect to drop it as your equity grows.
The Complete Guide
Private mortgage insurance protects the lender, not you, and is required on most conventional loans with less than 20% down. It is a real monthly cost, but it also lets you buy sooner instead of waiting years to save a full 20%.
Because PMI is tied to your loan-to-value, you control when it ends. Paying down principal, or a rise in your home's value confirmed by an appraisal, can let you cancel it ahead of the automatic schedule.
Compare PMI against alternatives. FHA loans carry their own mortgage insurance that often lasts the life of the loan, while a piggyback second mortgage can avoid PMI altogether. The right path depends on your down payment and credit.
How the Calculator Works
The calculator applies an estimated PMI rate to your loan amount to find the annual premium, divides by twelve for the monthly cost, and projects the point at which your balance reaches 78% to 80% of the original value, when PMI typically ends.
Frequently Asked Questions
When does PMI go away?
On a conventional loan, PMI automatically ends when your balance reaches 78% of the original value, and you can request cancellation at 80%. A new appraisal showing higher value can speed this up.
How can I avoid PMI?
Put at least 20% down on a conventional loan, use a VA or USDA loan if eligible, or consider a piggyback second mortgage. Each approach has trade-offs the calculator can help you weigh.
