The values on the left above the table are values specified in other tabs.

Mortgage Insurance Table
If you pay less than 20% down on the purchase price of your home, you have to pay mortgage insurance. This table shows you the percentage of the financed amount you will have to pay annually in mortgage insurance. The less you put down, the more mortgage insurance you have to pay. The table displays standard, conservative values. If you have been given different values by your lender, you can enter them in the appropriate cells of the table.
The left-hand column shows 4 rows of LTV (loan-to-value) percentages. If you put down 5%, you have a 95% LTV. The top row shows 4 columns representing typical loan terms.
If you purchase a home for $150,000 and put 10% down on a 30 year Fixed Rate Loan, you would be financing 90% of the purchase price ($135,000). In order to calculate the Private Mortgage Insurance, you would calculate with the following formula:
- financed amount X mortgage insurance factor = monthly mortgage insurance
- $135,000 x 0.0079 = $1,066.50
- $1,066.50 ÷ 12 months = $88.88
- your monthly mortgage insurance would be $88.88. Add this amount to your monthly mortgage payment.
