What Is PITI? Breaking Down Principal, Interest, Taxes, and Insurance

PITI is the acronym lenders use for the four pieces of a fully loaded mortgage payment:

• P — Principal: the part that reduces your loan balance.
• I — Interest: the cost of borrowing, charged on the remaining balance.
• T — Taxes: property taxes, paid to your local government.
• I — Insurance: homeowners insurance (and mortgage insurance, if required).

The "P" and "I" are calculated by the amortization formula. The "T" and "I" are estimates collected into an escrow account and paid by your servicer when due.

Why PITI Matters More Than P&I

A lender qualifies you on the full PITI payment, not just principal and interest. Two homes with the same price can have very different PITI because of property tax rates and insurance costs — a fact many first-time buyers discover only at closing.

Example

| Component | Monthly | |-----------|---------| | Principal & interest ($300k, 6.5%, 30-yr) | ~$1,896 | | Property taxes (est. 1.1%/yr on value) | ~$275 | | Homeowners insurance (est.) | ~$100 | | Mortgage insurance (if <20% down) | ~$130 | | Total PITI | ~$2,400 |

Here the escrow items add roughly $500 a month — more than a quarter-point rate change on the loan itself.

How Escrow Works

Each month you pay the same total. The servicer deposits the tax and insurance portions into an escrow account, then disburses them when bills come due (usually once or twice a year). Lenders require a cushion — typically up to two months of payments — so the account never runs short.

Once a year the servicer performs an escrow analysis: if taxes or insurance rose, your monthly payment is adjusted upward; if they fell, it may drop. This is why a "fixed" mortgage payment can still change year to year — the P&I is fixed, but the T&I are not.

Mortgage Insurance Inside PITI

• Conventional: required below 20% down, cancellable at 78–80% loan-to-value.
• FHA: mortgage insurance premium (MIP) is usually required for the life of the loan at low down payments.
• VA/USDA: no private mortgage insurance, though VA has a funding fee and USDA has a guarantee fee.

When mortgage insurance drops off (on a conventional loan), your PITI payment falls — a real, recurring saving.

The Practical Check

When comparing homes, estimate taxes and insurance for each, not just the price and rate. A cheaper house in a high-tax area can cost more per month than a pricier house in a low-tax area.
