Understanding Private Mortgage Insurance (PMI)

Private Mortgage Insurance (PMI) is a type of insurance that protects lenders if a borrower defaults on their mortgage. It's typically required when the down payment is less than 20% of the home's purchase price, resulting in a loan-to-value (LTV) ratio greater than 80%.

Types of PMI
  • Annual PMI: The most common type, paid monthly as part of your mortgage payment.
  • Monthly Premium PMI: Similar to annual PMI but with a different rate structure.
  • Upfront PMI: A one-time premium paid at closing.
  • Split Premium PMI: A combination of upfront and monthly premiums.
  • Lender-Paid PMI: The lender pays the PMI but typically charges a higher interest rate.
Factors Affecting PMI Cost
  • Down Payment Size: Larger down payments result in lower PMI costs.
  • Credit Score: Higher credit scores typically qualify for lower PMI rates.
  • Loan Term: Shorter loan terms may have lower PMI rates.
  • Loan Type: Conventional loans, FHA loans, and VA loans have different insurance requirements.
  • Property Type: Single-family homes often have lower rates than investment properties.
Removing PMI

For conventional loans, PMI can typically be removed when:

  • Your loan balance reaches 80% of the original purchase price (by request).
  • Your loan balance automatically reaches 78% of the original purchase price.
  • You're halfway through your loan term (e.g., 15 years on a 30-year mortgage).
  • You refinance with at least 20% equity.
  • You get a new appraisal showing your home's value has increased, resulting in an LTV ratio of 80% or less.

FHA loans have different rules. FHA mortgage insurance premiums (MIP) typically last for the life of the loan if the down payment is less than 10%. With a down payment of 10% or more, MIP can be removed after 11 years.

What Is a PMI Calculator?

A PMI Calculator helps you estimate how much Private Mortgage Insurance (PMI) you may need to pay on a home loan when your down payment is less than 20%. This mortgage payment tool assists in visualizing the impact of PMI on your monthly mortgage costs and helps you make informed financing decisions.

How the Calculation Works

The calculator determines your PMI cost based on factors like your home price, down payment, loan term, interest rate, credit score, and loan type.

Loan-to-Value (LTV) Ratio:
\( \text{LTV} = \left( \frac{\text{Loan Amount}}{\text{Home Price}} \right) \times 100 \)

Annual PMI:
\( \text{Annual PMI} = \text{Loan Amount} \times \text{PMI Rate} \)

Monthly PMI:
\( \text{Monthly PMI} = \frac{\text{Annual PMI}}{12} \)

How to Use the PMI Calculator

  • Enter the home purchase price.
  • Add your down payment in dollars or percentage.
  • Select your loan term and interest rate.
  • Choose your credit score range.
  • Pick a PMI type: Annual, Monthly, Upfront, or Split.
