Calculating Private Mortgage Insurance: What You Need To Know

Private mortgage insurance (PMI) is a type of insurance that lenders require for conventional mortgages with a high loan-to-value (LTV) ratio. It is required when the down payment is less than 20% of the purchase price or, for refinance loans, when the LTV ratio is over 80%. The cost of PMI varies depending on several factors, including the size of the loan, the down payment amount, debt-to-income ratio and credit score. The average annual PMI premium ranges from 0.46% to 1.50% of the original loan amount. To calculate PMI, you can use the following steps: identify the property value, find the total loan amount, calculate the LTV, and then estimate your annual PMI premium by multiplying the PMI percentage by the total loan amount. This will give you an estimate of your monthly PMI cost.

How to calculate the monthly premium

To calculate the monthly premium for private mortgage insurance (PMI), you'll need to know the property value, the total loan amount, the loan-to-value (LTV) ratio, and the PMI rate. Here's a step-by-step guide:

• Identify the property value: Use a recent appraisal or estimate how much you plan to offer for the house.
• Calculate the total loan amount: For a new mortgage, subtract your down payment from the home price.
• Find the LTV ratio: Divide the loan amount by the property value and multiply by 100 to get the percentage. If it's 80% or lower, you likely won't need PMI.
• Determine the annual PMI premium: The PMI rate depends on factors such as your down payment, credit score, debt-to-income ratio, and the lender. Multiply the PMI rate by the total loan amount to get the annual premium.
• Calculate the monthly premium: Divide the annual PMI premium by 12 to get the monthly cost.

For example, let's say you're buying a $500,000 house with a 10% down payment. The loan amount would be $450,000. Assuming a PMI rate of 0.3%, the calculations would be:

• Annual PMI premium: $450,000 x 0.3% = $1,350
• Monthly PMI premium: $1,350 / 12 = $112.50

So, your monthly PMI payment would be $112.50, added to your mortgage payment. Remember, PMI rates and calculations may vary, so be sure to consult a lender or financial advisor for a more precise estimate.

How the down payment amount affects the PMI rate

The down payment amount has a significant impact on the PMI rate. Private mortgage insurance (PMI) is typically required when a buyer makes a down payment of less than 20% of the home's purchase price or value. In this case, the buyer will need to pay PMI each month until they build up 20% equity in their home. The cost of PMI can vary depending on several factors, including the loan amount, credit score, loan-to-value (LTV) ratio, and the down payment.

A higher down payment amount can lead to a lower PMI rate since it reduces the loan amount and the LTV ratio. For example, a down payment of 15% would result in a lower PMI rate than a down payment of 10%. This is because the buyer is assuming more of the risk by putting more money down upfront, which lowers the lender's risk.

Additionally, the down payment amount can affect the type of PMI option available. For instance, with lender-paid PMI (LPMI), the lender covers the PMI costs, but the buyer pays a higher interest rate on the mortgage. This option may be more feasible for buyers who can make a larger down payment, as it reduces the overall interest costs.

On the other hand, a smaller down payment amount may result in a higher PMI rate. For example, a down payment of 5% would likely lead to a higher PMI rate than a down payment of 10%. This is because it will take longer for the buyer to reach 20% equity, and the lender is assuming more risk during this time.

It's important to note that PMI rates can vary among lenders, and it's always a good idea to shop around and compare rates before deciding on a lender. Additionally, there are ways to avoid PMI altogether, such as making a down payment of 20% or more, using a piggyback loan, or exploring first-time homebuyer programs that do not require PMI.

How to calculate the LTV

To calculate the loan-to-value (LTV) ratio, you need to divide the amount you owe on your current mortgage by the appraised value of your home.

Here's the formula:

> LTV = current loan balance ÷ current appraised value

Let's say you currently have a loan balance of $140,000 and your home currently appraises for $200,000. Your LTV equation would be:

> $140,000 ÷ $200,000 = .70

To get the LTV as a percentage, simply convert .70 to a percentage, giving you an LTV of 70%.

Lenders use the LTV ratio to assess the level of risk they take on when underwriting a mortgage. A higher LTV ratio indicates a higher-risk loan, which may result in a higher interest rate and the requirement to purchase private mortgage insurance (PMI). Typically, an LTV of 80% or lower is considered favourable, while an LTV above 80% is considered high and may lead to higher borrowing costs or the need for PMI.

If you're considering a home equity line of credit, you would calculate the combined loan-to-value (CLTV) ratio, which includes any additional loans or credit limits secured by your home. Here's the formula:

> CLTV = current combined loan balance ÷ current appraised value

For example, if you have a loan balance of $140,000 and want to take out a $25,000 home equity line of credit on a home that appraises for $200,000, your CLTV equation would be:

> $165,000 ÷ $200,000 = .825

Converting .825 to a percentage gives you a CLTV of 82.5%. Most lenders require a CLTV of 85% or less for a home equity line of credit.

By understanding how to calculate your LTV and CLTV ratios, you can make more informed financial decisions and explore various financing options available to you.

How to estimate the annual premium

To estimate the annual premium for private mortgage insurance, you need to consider several factors. These include the size of your loan, your down payment amount, debt-to-income ratio, credit score, and loan-to-value (LTV) ratio.

Firstly, you need to identify the property value, either through a recent appraisal or by estimating how much you plan to offer for the house. Next, calculate the total loan amount by subtracting your down payment from the property value.

Then, calculate the LTV ratio by dividing the loan amount by the property value and multiplying by 100. If the LTV is 80% or lower, you likely won't need to pay for private mortgage insurance.

If your LTV is higher than 80%, you can estimate your annual PMI premium by multiplying the PMI percentage provided by your lender by the total loan amount. You can then divide this figure by 12 to get your monthly premium.

For a more precise estimate, you can use online PMI calculators, which take into account factors such as credit score, loan term, interest rate, and home price to give you a more accurate monthly PMI cost.

How to avoid paying PMI

Paying for private mortgage insurance (PMI) can be an expensive requirement for getting a home loan. Fortunately, there are ways to make a down payment of less than 20% without paying PMI premiums on your monthly mortgage payment. Here are some ways to avoid paying PMI:

• Make a 20% down payment: A larger down payment offers advantages beyond lowering the monthly mortgage payment and avoiding PMI. You’ll also get a lower mortgage interest rate and own a bigger stake in your home right away.
• Pay a higher interest rate for a "no PMI loan": In some cases, lenders will pay for PMI and charge a higher interest rate on the mortgage instead. This is known as lender-paid mortgage insurance (LPMI).
• Get an 80-10-10 loan: Sometimes called a “piggyback loan,” an 80-10-10 loan lets you buy a home with two loans that cover 90% of the home price. One loan covers 80% of the home price, and the other loan covers a 10% down payment. Combined with your savings for a 10% down payment, this type of loan can help you avoid PMI.
• Get a VA loan: VA loans are backed by the Department of Veterans Affairs and are for current and veteran service members and eligible spouses. They don't require a down payment or mortgage insurance, although there is a one-time funding fee.
• Explore USDA loans: USDA loans are backed by the U.S. Department of Agriculture and are zero-down mortgages for lower- and moderate-income buyers in designated rural and suburban areas. Although USDA loans don't require mortgage insurance, they come with upfront and annual fees.
• Look into special loans for medical professionals: Some lenders offer special low- or no-down-payment mortgages for physicians, dentists and orthodontists that don't require PMI.
• Check state housing finance agency programs: State housing finance agencies offer mortgage and down payment assistance programs that sometimes include low-down-payment mortgages that feature reduced-cost mortgage insurance or don't require PMI.
