Expert Analysis & Methodology

Mortgage Calculator Pro

Calculate your true monthly housing payment with PITI (Principal, Interest, Taxes, Insurance).

Breaking Down 'PITI'

Your mortgage payment is more than just the loan. Lenders usually collect 4 things in one check:

  1. Principal: The money that actually pays down your loan balance. This builds equity.
  2. Interest: The fee the bank charges you. In the first few years, your payment is mostly interest.
  3. Taxes (Property Tax): The bank collects this monthly and pays your county/city government once a year.
  4. Insurance: Homeowners insurance protects the asset.

The 28/36 Rule

Financial advisors use this rule to check affordability:

  • Housing Ratio (28%): Your PITI payment should not exceed 28% of your gross monthly income.
  • Debt Ratio (36%): Your total debt payments (House + Car + Student Loans + Credit Cards) should not exceed 36% of gross income.

[!IMPORTANT] PMI (Private Mortgage Insurance): If you put down less than 20%, you will likely pay an extra fee called PMI. This protects the lender, not you. Aim for 20% down to remove this cost.
