How to use it
- Enter the loan amount in dollars.
- Input the monthly PMI rate (e.g., 0.005).
- Specify how many months you’ll pay off the loan.
- View the monthly payment and total cost instantly.
What it does – The PMI Calculator takes your loan principal, the monthly PMI rate, and the payoff period to show two numbers: the monthly PMI payment and the total amount you’ll pay in PMI over the life of the loan. Why it matters – PMI can add hundreds or thousands to your monthly outflow and significantly increase the cost of homeownership. Knowing the exact monthly figure helps you budget, compare loan offers, and decide if a larger down payment or refinancing makes sense. How to read it – The Monthly PMI Payment is the loan amount multiplied by the rate you entered. Multiply that by the Months to Pay Off to see the Total PMI Cost you’ll incur if the rate stays constant.
Pro tips
- Round the loan amount to the nearest thousand for a quick estimate.
- Use the exact rate from your lender to avoid under‑estimating.
- Check if your PMI drops when you reach 20% equity.
- Remember the total cost assumes the rate stays constant for the entire term.

Case study
Sarah bought a $250,000 house with a 0.006 monthly PMI. Using the calculator she saw a $1,500 monthly PMI and $162,000 total over 9 years, letting her decide to make a larger down payment and cut her PMI cost by $30,000.
