When lenders estimate your monthly mortgage payment, they usually break it into four core costs: principal, interest, property taxes, and homeowners insurance. Together, these costs are known as PITI.
Understanding PITI helps you estimate your true monthly housing payment, compare mortgage offers, and see how lenders determine what you may be able to afford.
In this guide, you'll learn what each part of PITI means, see a worked example for a $350,000 home, and understand which homeownership expenses are included—and which are not.
You can also use the Mortgage Calculator to estimate PITI and other monthly housing costs with your own inputs.

What Does PITI Stand For?
PITI stands for the four primary components that often make up a monthly mortgage payment.
| Letter | Component | What It Covers |
|---|---|---|
| P | Principal | Repayment of the amount borrowed |
| I | Interest | The cost of borrowing the money |
| T | Property Taxes | Taxes assessed by your local government |
| I | Homeowners Insurance | Insurance protecting the home against covered risks |
Many lenders collect these costs together as one monthly payment through an escrow account. A total monthly mortgage payment may also include mortgage insurance when it applies.
For underwriting, PITIA refers to the housing expense used in the lender's analysis. Depending on the property and loan, it may include association dues, special assessments, mortgage insurance, and other applicable housing obligations in addition to principal, interest, property taxes, and homeowners insurance. It is not simply another name for PITI whenever HOA dues apply.
Why PITI Matters
Understanding PITI helps you:
- Estimate your total monthly housing payment
- Compare different mortgage offers fairly
- Understand how lenders evaluate affordability
- Budget beyond just the loan payment
- Avoid underestimating the true cost of owning a home
Principal: The Loan Amount You're Repaying
Principal is the amount you borrow from the lender to purchase the home.
Each monthly payment reduces the remaining loan balance. On a fixed-rate mortgage, the scheduled principal-and-interest payment generally stays the same, but the portion applied to principal gradually increases over time. Property taxes, homeowners insurance, and therefore the total monthly payment can still change.
Example
- Home price: $350,000
- Down payment (20%): $70,000
- Loan amount: $280,000
As the loan balance decreases, less interest accrues and more of each payment goes toward principal.
Interest: The Cost of Borrowing
Interest is what the lender charges for providing the loan.
It is calculated on the remaining loan balance.
During the early years of a 30-year mortgage, most of the principal-and-interest payment goes toward interest. Over time, the balance declines, interest charges decrease, and a larger share of each payment goes toward principal.
This is also why making extra payments earlier in the loan generally saves more interest than making the same extra payments later.
Property Taxes
Property taxes help fund local services such as schools, roads, emergency services, and public infrastructure.
Many lenders collect one-twelfth of the annual property tax bill each month through escrow and pay the taxes when they become due.
Property taxes vary based on:
- State
- County or municipality
- Assessed property value
- Local tax rates
Homeowners Insurance
Mortgage lenders generally require homeowners insurance before closing.
Insurance protects the home against covered losses, such as fire, wind, theft, or certain types of weather damage.
Like property taxes, insurance premiums are often collected monthly through escrow.
Premiums depend on factors including:
- Property location
- Construction type and age
- Coverage limits
- Deductible
- Insurance provider
PITI Example: $350,000 Home
Assume the following:
| Item | Value |
|---|---|
| Home price | $350,000 |
| Down payment | $70,000 (20%) |
| Loan amount | $280,000 |
| Interest rate | 6.50% |
| Loan term | 30 years |
| Property taxes | $4,200/year |
| Homeowners insurance | $1,500/year |
Step 1: Principal & Interest
Estimated monthly principal and interest payment:
$1,769.79
Step 2: Property Taxes
Annual property taxes:
$4,200
Monthly property taxes:
$350
Step 3: Homeowners Insurance
Annual premium:
$1,500
Monthly insurance:
$125
Estimated Monthly PITI
| Component | Monthly Cost |
|---|---|
| Principal & Interest | $1,769.79 |
| Property Taxes | $350.00 |
| Homeowners Insurance | $125.00 |
| Estimated PITI Payment | $2,244.79 |
This example assumes no PMI and no HOA dues. Actual payments vary based on your loan terms, location, insurance premium, and property taxes.

What's Included in PITI?
PITI generally includes:
- ✅ Principal
- ✅ Interest
- ✅ Property taxes
- ✅ Homeowners insurance
If taxes and insurance are escrowed, the lender collects these amounts every month and pays them on your behalf when they become due.
What's NOT Included in PITI?
PITI covers the core mortgage payment, but it does not include every cost of owning a home.
| Cost | Included in PITI? |
|---|---|
| HOA dues | ❌ No |
| Utilities | ❌ No |
| Internet & cable | ❌ No |
| Maintenance & repairs | ❌ No |
| Landscaping | ❌ No |
| Appliance replacement | ❌ No |
| Closing costs | ❌ No |
| Moving expenses | ❌ No |
Maintenance is not part of PITI, and there is no universal percentage that fits every property. A practical budget depends on the home's age, condition, systems, location, warranties, and likely repair needs. See The True Cost of Homeownership for a broader planning framework.
Does PITI Include PMI?
No.
Private Mortgage Insurance (PMI) is not part of the PITI acronym.
However, borrowers making less than a 20% down payment on certain conventional loans may be required to pay PMI in addition to PITI.
When PMI applies, lenders sometimes refer to the total payment as PITI + PMI, or simply the total monthly mortgage payment.
For many covered conventional loans, a borrower may be able to request PMI cancellation when the principal balance reaches 80% of the home's original value, subject to applicable conditions. Automatic termination is generally tied to the date the balance is scheduled to reach 78% of the original value, provided payments are current. PMI rules vary by loan type and individual circumstances, so confirm the requirements with your servicer.
Why Lenders Use PITI
Lenders use PITI because it provides a more complete picture of your monthly housing costs than principal and interest alone.
Monthly housing expenses are commonly evaluated alongside your other recurring debts when calculating your debt-to-income (DTI) ratio.
The 28/36 rule is a traditional budgeting guideline that compares housing costs and total recurring debts with gross income. It is not a universal lender approval standard, and actual underwriting criteria vary by lender, loan program, and borrower profile.
Lenders may use a broader PITIA housing expense in their analysis when association dues, special assessments, mortgage insurance, or other applicable housing obligations must be counted.

Frequently Asked Questions
Is PITI the same as my total mortgage payment?
Often, but not always.
If mortgage insurance or other required housing costs apply, your total monthly mortgage payment may be higher than PITI alone. Association dues are often paid separately, but they still affect the total monthly housing expense used for budgeting or underwriting.
How can I lower my PITI payment?
You may be able to reduce your payment by:
- Making a larger down payment
- Qualifying for a lower interest rate
- Comparing homeowners insurance quotes
- Purchasing a less expensive home
- Reducing property taxes through available exemptions, where applicable
Does PITI change over time?
The scheduled principal-and-interest payment on a fixed-rate mortgage generally remains the same.
However, property taxes and homeowners insurance premiums may increase or decrease over time, changing your total monthly payment.
What is a good PITI-to-income ratio?
There is no single ratio that guarantees affordability or loan approval. The 28/36 rule is a traditional budgeting guideline, while lender requirements vary by loan program, borrower profile, and other underwriting factors.
Can I calculate PITI without escrow?
Yes.
Even if you pay property taxes and homeowners insurance directly instead of through an escrow account, PITI remains a useful way to estimate your monthly housing costs.
