What it does The PMI Monthly Cost Calculator takes your loan amount and the monthly PMI rate you’ve been quoted and instantly shows the dollar amount you’ll pay each month for private mortgage insurance.
Why it matters PMI can add hundreds or thousands to your housing expense. Knowing the exact monthly cost helps you compare loan offers, decide whether to make a larger down payment, or refinance to eliminate PMI.
How to read the result The output is a single dollar figure. Multiply it by 12 to see the annual PMI expense, then add it to your mortgage payment to get the total monthly out‑flow.
Example Loan: $200,000 Rate: 0.0075 (0.75%) Monthly PMI = $200,000 × 0.0075 = $1,500. Use this figure in your budgeting spreadsheet to see how PMI impacts your cash flow and to plan for the month you can drop the insurance.
Pro tips
- Round the loan amount to the nearest thousand for a quick sanity check.
- Keep the PMI rate to three decimal places to avoid rounding errors.
- Enter the rate as a decimal, not a percentage, to get the correct result.
- Double‑check that the rate falls within the typical 0.5%‑1% monthly range.
