1. What is the PITI Formula?

PITI is an acronym that stands for Principal, Interest, Taxes, and Insurance. It represents the total monthly mortgage payment that a borrower will make. Understanding PITI is crucial for homebuyers to accurately budget for homeownership costs.

2. How Does the Calculator Work?

The calculator uses the PITI formula:

Where:

• \( P \) — Principal portion of the mortgage payment
• \( I \) — Interest portion of the mortgage payment
• \( T \) — Property taxes
• \( I \) — Homeowners insurance

Explanation: The formula sums up all four components to give the total monthly housing payment that a borrower is responsible for.

3. Importance of PITI Calculation

Details: Calculating PITI is essential for mortgage qualification, as lenders use this figure to determine debt-to-income ratios. It also helps homebuyers understand the true cost of homeownership beyond just the mortgage principal and interest.

4. Using the Calculator

Tips: Enter each component of your mortgage payment in dollars. All values must be non-negative numbers representing monthly amounts.
