How to use it
- Enter the loan amount in dollars.
- Enter the appraised value of the property.
- Click Calculate.
- Read the PMI rate percentage displayed.
The PMI Rate Calculator tells you the private‑mortgage‑insurance percentage you’ll pay based on your loan‑to‑value ratio. PMI is required when you put less than 20 % down, and the rate directly affects your monthly payment. The tool takes two numbers—your loan amount and the property’s appraised value—computes LTV, then multiplies by the fixed 0.85 % factor used for conventional loans. For example, a $200,000 loan on a $250,000 appraisal gives an LTV of 80 % and a PMI rate of 0.68 %. The result appears as a clear percentage you can plug into your budgeting spreadsheet or mortgage quote. No hidden steps, no sign‑up, just an instant, reliable figure to help you compare loan options. Lenders use this rate to calculate the monthly PMI charge, so knowing it early lets you decide whether a larger down payment or a different loan program saves you money.
Pro tips
- Round the LTV to two decimals before applying the 0.85 % factor for a tidy result.
- Enter whole dollar amounts; the calculator handles cents but they rarely change the rate meaningfully.
- If your appraisal is higher than the loan, the PMI rate will be lower—use the highest recent appraisal for safety.
- Double‑check that you’re using the loan amount you actually plan to borrow, not the purchase price.
Real-life examples

Case study
Sara needed to know her PMI cost before buying a $300,000 home. Using the calculator with a $60,000 loan and $300,000 appraisal, she saw a 0.51 % PMI rate, helping her decide to add $10,000 to the down payment and save $150 per month.
