Understanding PITI: Principal, Interest, Taxes, and Insurance

When purchasing a home, your monthly housing expense consists of more than just the loan principal and interest repayment. Financial professionals use the acronym PITI to represent the four primary components of a monthly mortgage payment:

• Principal: The portion of your payment that directly reduces the outstanding loan balance.
• Interest: The fee charged by the lender for borrowing money.
• Taxes: Real estate property taxes collected by your local municipality or county government.
• Insurance: Homeowners insurance protecting the property against hazards, fire, and natural disasters.

Additional Costs: HOA Fees and PMI

Depending on your property location and down payment size, two additional monthly expenses may be added:

• Private Mortgage Insurance (PMI): Required by conventional lenders when your down payment is less than 20% of the purchase price. PMI protects the lender in case of default.
• Homeowners Association (HOA) Dues: Mandatory monthly or annual fees assessed by condo boards or neighborhood associations for shared amenities and maintenance.

PITI Calculation Formula

The total monthly mortgage payment is given by:

$$\text{Total Payment} = \text{EMI}_{\text{P\&I}} + \frac{\text{Annual Property Tax}}{12} + \frac{\text{Annual Insurance}}{12} + \text{HOA} + \text{PMI}$$
