Understanding Your Mortgage Components

A mortgage payment is more than just paying back the money you borrowed. When you use our Nationwide Mortgage Calculator, you'll see a breakdown commonly referred to as PITI:

  • Principal

    The part of your payment that lowers your loan balance. In the early years, this is small, but it grows over time.

  • Interest

    The fee the lender charges. On a 30-year fixed loan, your initial payments are mostly interest.

  • Taxes

    Local governments charge property taxes to fund schools and services. This is usually held in escrow.

  • Insurance

    Homeowners insurance protects against damage. Like taxes, this is often bundled into your monthly bill.

Save on Interest

Consider making one extra mortgage payment each year. This simple trick can shave years off your loan term.

Avoid PMI

Aim for a 20% down payment to avoid Private Mortgage Insurance costs, which don't build any equity.
