What Is PITI?
In plain English
PITI stands for Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment. Lenders use your total PITI payment to determine how much house you can afford by comparing it to your gross monthly income. Understanding PITI gives you the full picture of your housing cost beyond just the loan payment.
What Are the Four Components of PITI?
Principal is the portion that reduces your loan balance. Interest is the cost of borrowing, determined by your rate and remaining balance. Taxes are property taxes collected monthly by your lender and held in escrow. Insurance includes homeowners insurance and, if applicable, [private mortgage insurance (PMI)](/glossary/private-mortgage-insurance). Together, these define your true monthly housing cost.
How Do Lenders Use PITI?
Lenders calculate your front-end ratio by dividing your PITI by gross monthly income. Most conventional loans require this ratio to be 28% or less. FHA loans allow up to 31%. This ratio helps ensure you can comfortably afford your home. A $6,000 gross monthly income, for example, supports a PITI of up to $1,680 under the 28% guideline.
Why Does PITI Change Over Time?
Even with a fixed-rate mortgage, your PITI can change. Property taxes are reassessed periodically and often increase. Homeowners insurance premiums may rise. If your escrow analysis shows a shortfall, your lender will adjust the monthly escrow portion upward. Only the principal and interest portions stay constant on a fixed-rate loan.
Frequently asked questions
Is PITI the same as my mortgage payment?
PITI represents the total payment most homeowners make, but some costs like HOA fees are not included. If your lender does not escrow taxes and insurance, your mortgage payment may only cover principal and interest, and you pay taxes and insurance separately.
How can I lower my PITI payment?
You can lower PITI by making a larger down payment, buying mortgage points to reduce your rate, shopping for cheaper homeowners insurance, appealing your property tax assessment, or eliminating PMI once you reach 20% equity.

Mortgage
A mortgage is a loan used to purchase real estate, where the property itself serves as collateral. It's typically repaid over 15 or 30 years through monthly payments of principal and interest.
Escrow
Escrow is a neutral holding arrangement where funds or documents are held by a third party until transaction conditions are met. In real estate, it applies both to the closing process and to ongoing tax and insurance payments.
Private Mortgage Insurance (PMI)
Private mortgage insurance protects the lender — not you — if you default on a conventional loan with less than 20% down. It adds a monthly cost until you build enough equity to cancel it.
Down Payment
A down payment is the upfront cash you pay toward a home purchase, with the mortgage covering the rest. The larger your down payment, the less you borrow and the lower your monthly payments.
