ARM PMI Calculator

Merchants Home Lending provides this calculator to help borrowers estimate PMI expenses and better understand the total cost of financing an adjustable rate mortgage.

How the ARM PMI Calculator Works

The ARM PMI Calculator estimates your monthly PMI cost based on your loan details and down payment.

Enter the following information:

• Home purchase price
• Down payment amount
• Loan amount
• Estimated PMI rate
• Initial ARM interest rate
• Loan term
• Property taxes
• Homeowners insurance

The calculator estimates:

• Loan to value (LTV) ratio
• Estimated monthly PMI payment
• Monthly principal and interest payment
• Total estimated monthly mortgage payment

This estimate helps borrowers understand the additional cost of PMI before purchasing a home.

What the Calculator Includes

Home Purchase Price

The purchase price determines the starting point for calculating the loan amount and loan to value ratio.

Down Payment

The amount paid upfront reduces the loan balance. Down payments below 20% generally require PMI on conventional loans.

Loan to Value Ratio

The loan to value (LTV) ratio compares the mortgage amount to the home's value. Higher LTV ratios generally result in higher PMI costs.

PMI Premium

PMI is usually paid monthly and depends on factors such as the loan amount, down payment, credit profile, and lender requirements.

Monthly Mortgage Payment

The calculator combines principal, interest, estimated PMI, property taxes, and homeowners insurance to estimate the total monthly housing payment.

Frequently Asked Questions

What is PMI?
Private Mortgage Insurance (PMI) protects the lender if the borrower defaults on the loan. It is commonly required for conventional loans with a down payment of less than 20%.

Does every ARM require PMI?
No. PMI is generally required only if your conventional ARM has a loan to value ratio above 80%. Government backed loans may have different mortgage insurance requirements.

Can PMI be removed?
In many cases, PMI may be removed once you reach the lender's required equity level or qualify under applicable loan servicing rules.

Does PMI affect my interest rate?
No. PMI is a separate insurance cost added to your monthly mortgage payment and does not change your loan's interest rate.

Are the calculator results guaranteed?
No. The calculator provides estimates based on the information entered. Your actual PMI cost will depend on your loan program, lender requirements, credit profile, and other underwriting factors.

Understanding the cost of Private Mortgage Insurance is an important part of budgeting for a home purchase.
