What Is PITI?

PITI stands for Principal, Interest, Taxes, and Insurance — the four components that make up your total monthly mortgage payment. Lenders use your total PITI to determine whether you can afford a home, and it’s one of the most important numbers in the mortgage qualification process.

What Each Component Means

Principal is the portion of your payment that reduces your loan balance. Early in the loan, only a small fraction goes toward principal. Over time, that share grows as the balance decreases.

Interest is the cost of borrowing money, calculated based on your interest rate and remaining balance. Interest charges are highest in the early years of a mortgage because the balance is at its largest.

Taxes refers to property taxes collected monthly through your escrow account. Your lender divides your annual tax bill by 12 and adds that amount to each payment.

Insurance covers homeowners insurance, which protects the property against damage and loss. If your down payment is less than 20%, your PITI also includes mortgage insurance — either PMI on conventional loans or MIP on FHA loans.

A Realistic PITI Breakdown

Here’s what PITI looks like on a $350,000 home purchase with 5% down on a 30-year conventional loan at 6.0%:

Component	Monthly Amount
Principal & Interest	$1,994
Property Tax (~1.1%)	$321
Homeowners Insurance	$150
PMI (~0.55%)	$153
Total PITI	$2,618

The principal and interest portion ($1,994) stays fixed on a fixed-rate mortgage, but the taxes, insurance, and PMI portions can all change over time.

Why PITI Matters for Qualification

Lenders use your total PITI to calculate your debt-to-income ratio (DTI), which is one of the biggest factors in determining how much home you can afford. Your front-end DTI — just PITI divided by your gross monthly income — should generally stay below 28% to 31% depending on the loan program.

For example, if you earn $8,000 per month gross and your total PITI is $2,618, your front-end DTI is about 33%. Some loan programs will allow this, but it leaves less room in your budget. Reducing any component of PITI — through a larger down payment, a lower rate, or a home in a lower-tax area — improves your qualification profile.

PITI Can Change Over Time

Even with a fixed-rate mortgage, your total PITI can change. Here’s why:

• Property taxes get reassessed, and rates can increase through local government decisions
• Homeowners insurance premiums can rise, especially in areas prone to hurricanes, wildfires, or flooding
• PMI can be removed once you reach 20% equity on a conventional loan, reducing your monthly payment
• Adjustable-rate mortgages can change the interest portion of your payment after the fixed period ends

Your lender reviews your escrow account annually and adjusts the taxes and insurance portion of your payment to reflect any changes. This is the most common reason a mortgage payment increases even when the rate is fixed.

Key Facts

• What it stands for: Principal, Interest, Taxes, and Insurance
• Front-end DTI target: PITI should generally be under 28%–31% of gross income
• Escrow: The T and I portions are typically collected monthly and held in an escrow account
• PMI inclusion: If your down payment is under 20%, mortgage insurance is included in the total PITI figure
• Annual adjustment: Your lender reviews escrow yearly and may adjust your payment for tax or insurance changes

Frequently Asked Questions

What is a good PITI-to-income ratio?

Most lenders look for a front-end DTI (PITI divided by gross income) of 28% or less for conventional loans, though many programs allow up to 31% or higher with strong compensating factors like excellent credit or large reserves. FHA guidelines are more flexible, sometimes allowing front-end ratios up to 46.9% with automated approval.

Can my PITI payment change after closing?

Yes. While the principal and interest portion stays fixed on a fixed-rate loan, the taxes and insurance portions are reviewed annually through your escrow account. If your property taxes increase or your insurance premium goes up, your lender will adjust your monthly payment accordingly. This is the most common reason homeowners see their mortgage payment change.

Does PITI include HOA dues?

Not technically. PITI only covers Principal, Interest, Taxes, and Insurance. However, if you’re buying in a community with HOA dues, lenders do include those in their overall affordability assessment. Your total housing cost — PITI plus HOA — is what gets measured against your income for qualification purposes.
