PMI Calculator
Estimate monthly and annual private mortgage insurance using home price, down payment, loan amount, and PMI rate.
Our PMI Calculator helps you estimate how much private mortgage insurance may add to your housing cost. Here's how to use it:
Step 1: Enter the home price.
Step 2: Enter your down payment.
Step 3: Enter the annual PMI rate.
Step 4: Enter the loan term in years for context.
Step 5: Click 'Calculate' to see your loan amount, down payment percentage, loan-to-value ratio, annual PMI cost, and monthly PMI estimate.
PMI is commonly estimated from the loan amount:
Loan Amount = Home Price - Down Payment LTV = Loan Amount / Home Price × 100 Annual PMI = Loan Amount × PMI Rate Monthly PMI = Annual PMI / 12
This makes PMI highly sensitive to both the home price and the size of your down payment.
Private mortgage insurance, or PMI, is an added cost many buyers face when purchasing a home with a smaller down payment. In practice, the most useful planning questions are how much PMI adds each month and how your down payment changes your LTV. This calculator focuses on that planning view by translating home price, down payment, and PMI rate into clear monthly and annual costs.
