What is PITI? It stands for principal, interest, taxes and insurance. Those four costs make up the basic monthly payment on a PITI mortgage. Principal and interest repay the loan, while property taxes and homeowners insurance cover costs tied to the home.
For example, a $350,000, 30-year mortgage at a hypothetical 6.5% fixed rate has a monthly principal and interest payment of about $2,212. Add $400 for property taxes and $150 for homeowners insurance, and the estimated PITI is about $2,762 per month.
Lenders use PITI to judge affordability.

What Does PITI Mean on a Mortgage?
PITI describes the main recurring costs of owning a financed home, and lenders qualify you on that full payment.
With an escrow account for taxes and insurance, your servicer collects a share of those bills with each payment and pays them when due.
Without escrow, you still owe both bills. You just pay them yourself.
What Does Each Part of PITI Cover?
Principal
Principal is the money you borrowed and haven't repaid. On a $350,000 mortgage, your original principal is $350,000.
Each amortizing payment sends a growing share to principal over time. Our guide to loan principal vs. interest shows how that split shifts.
Interest
Interest is what the lender charges you to borrow. Your rate and unpaid balance set the interest portion of each payment.
On a fixed-rate, fully amortizing loan, the principal-and-interest payment never changes. With an adjustable-rate mortgage (ARM), it can change after the introductory period, within the loan's rate caps.
Property Taxes
State and local governments assess property taxes based on their own rules for value, rates and exemptions. To estimate PITI, divide the annual bill by 12. For example, $4,800 in annual property taxes adds $400 per month.
The seller's tax bill may not match yours. Some jurisdictions reassess property or change exemptions when ownership changes.
Homeowners Insurance
Homeowners insurance covers specified losses to the home, subject to the policy's deductibles and exclusions. Lenders require it for as long as the home secures the loan, and you'll show proof at closing with an insurance binder from your insurer.
Divide the annual premium by 12. An $1,800 annual premium adds $150 per month.
Premiums can change at renewal, and your lender can also require flood insurance if the home sits in a designated flood zone.
How to Calculate PITI
Use this basic formula to estimate the monthly housing payment:
PITI = Monthly Principal and Interest + (Annual Property Taxes / 12) + (Annual Homeowners Insurance / 12)
First, find the monthly principal-and-interest payment from the loan amount, rate and term. Then add one-twelfth of your annual tax and insurance bills.
PITI Calculation Example on a $350,000 Mortgage
Suppose you borrow $350,000 at a hypothetical fixed rate of 6.5% for 30 years. Annual property taxes are $4,800, and the annual homeowners insurance premium is $1,800.
| Payment Component |
Monthly Amount |
| Principal and Interest |
$2,212 |
| Property Taxes ($4,800 / 12) |
$400 |
| Homeowners Insurance ($1,800 / 12) |
$150 |
| Total Estimated PITI |

How Do You Calculate Principal and Interest?
On a fixed-rate mortgage, three inputs set principal and interest: the balance, the monthly rate and the number of payments. A longer term lowers the monthly payment but raises total interest if you keep the loan to term.
Repaying $350,000 over 15 years instead of 30, for example, raises the monthly payment. Our amortization calculator shows how each payment splits.
Does PITI Include Mortgage Insurance or HOA Fees?
Strictly, PITI covers only principal, interest, property taxes and homeowners insurance. Lenders add private mortgage insurance (PMI), FHA mortgage insurance, flood insurance and HOA or condo dues to the payment you must qualify for. With association dues included, the total is often called PITIA.
Does PITI Include PMI?
PMI has no letter in the acronym, but lenders count it. If your basic PITI is $2,762 and PMI costs $120 per month, the qualifying payment is $2,882 before any association fees.
On most conventional loans, you can cancel PMI once you meet the loan-to-value and payment-history requirements. FHA mortgage insurance follows different rules.
Does PITI Include HOA or Condominium Dues?
HOA and condo dues aren't part of PITI, but they count toward the qualifying housing expense. Adding $200 in monthly HOA dues to the $2,762 PITI above gives a monthly housing cost of $2,962 before mortgage insurance.
Dues can also rise, and associations can levy special assessments.
Does PITI Include Utilities and Repairs?
No. Electricity, gas, water, internet, maintenance and most repairs fall outside PITI.
Budget for them anyway. A payment that fits the lender's limits can still leave little room for a new roof or a cold winter.
How Do Mortgage Lenders Use PITI?
Lenders plug the housing payment into your debt-to-income ratio (DTI). DTI compares your required monthly debt payments with your gross monthly income, as the CFPB explains.
Suppose your gross income is $7,000 per month, your housing payment is $2,800 and your other debts total $500. Your total DTI is $3,300 divided by $7,000, or about 47.1%.
Each loan program sets its own DTI limits.
What Is the Front-End Housing Ratio?
The front-end ratio compares your housing payment with gross monthly income. In the example above, $2,800 divided by $7,000 equals 40%.
Not every program limits it.
Fannie Mae's Selling Guide DTI rules cap only the total ratio. FHA's manual underwriting rules in HUD Handbook 4000.1 set a 31% housing ratio and 43% total ratio without compensating factors, with higher ratios allowed when they're present.
What Is the Back-End DTI Ratio?
The back-end ratio adds recurring debts, such as auto loans, student loans and credit card minimums, to the housing payment. For the same borrower, $2,800 in housing costs plus $500 in other debts produces a 47.1% back-end DTI.
Fannie Mae caps total DTI at 36% on manually underwritten loans, or 45% with qualifying credit scores and reserves. Loans run through its Desktop Underwriter system can reach 50%. See DTI limits by loan type for other programs.
Can Your PITI Payment Change?
Yes. Even on a fixed-rate mortgage, PITI moves when property taxes or insurance premiums change.
Say principal and interest stay at $2,212. The monthly tax estimate rises from $400 to $475, and insurance rises from $150 to $175. Your total PITI climbs from about $2,762 to $2,862.
With an ARM, principal and interest also change when the rate adjusts.
What Is an Escrow Shortage?
An escrow shortage happens when the account balance falls below what the servicer's analysis requires. Higher taxes, higher premiums or low earlier estimates cause most shortages.
After the annual analysis, the servicer raises your monthly escrow deposit to cover the gap, so your payment rises even at a fixed rate.
Read more on escrow shortages and escrow analysis.
Is an Escrow Account Required?
It depends on the loan and lender. Many government-backed mortgages require escrow, while some conventional borrowers can waive it. See escrow requirements by mortgage type.
Waiving escrow doesn't remove the bills. You pay them directly instead.
How Can You Lower Your Monthly PITI Payment?
A smaller loan lowers principal and interest. Lower taxes or premiums shrink the escrow portion.
Borrow Less or Make a Larger Down Payment
A larger down payment means a smaller loan and a lower payment at the same terms. It can also reduce or eliminate mortgage insurance.
Compare Mortgage Rates and Loan Terms
A lower rate reduces principal and interest, but weigh discount points and closing costs. A longer term lowers the monthly payment and raises total interest.
Review Property Taxes and Insurance
Check for property tax exemptions and confirm your assessment is accurate.
Shop insurance on coverage, deductibles and price, but remember a cheaper policy shifts more risk to you and your lender sets minimum coverage.
Review Mortgage Insurance Requirements
On conventional loans, you can cancel PMI once you meet the requirements, while FHA follows its own rules. Dropping mortgage insurance lowers your payment without changing principal and interest.
The Bottom Line
PITI stands for principal, interest, taxes and insurance, and it shows your real monthly cost better than principal and interest alone. Lenders add mortgage insurance and association dues when they qualify you. Budget for the full payment plus utilities and upkeep.
Frequently Asked Questions
What Does PITI Stand For?
PITI stands for principal, interest, taxes and insurance, the four parts of a basic monthly mortgage payment.
How Do You Calculate PITI?
Add your monthly principal and interest to one-twelfth of your annual property taxes and one-twelfth of your annual homeowners insurance premium.
What Is a PITI Payment?
It's the combined monthly amount for principal, interest, property taxes and homeowners insurance.
Does PITI Include PMI?
PMI isn't in the acronym, but lenders count it in the qualifying housing payment when your loan requires it.
Does PITI Include HOA Fees?
No, but lenders count HOA or condo dues in the qualifying housing payment.
Is PITI the Same as a Mortgage Payment?
It is when taxes and insurance are escrowed. Without escrow, your servicer collects only principal and interest.
Can PITI Go Up on a Fixed-Rate Mortgage?
Yes. Principal and interest stay fixed, but taxes and insurance can rise.
Does PITI Include Utilities?
No. Water, electricity, gas and internet sit outside PITI.
Does PITI Include Flood Insurance?
Basic PITI refers to homeowners insurance, but lenders include required flood insurance in the qualifying payment.
What Does PITIA Mean?
PITIA means principal, interest, taxes, insurance and association dues.
What Is the Difference Between Principal and Interest?
Principal is the amount you owe. Interest is the cost of borrowing it.
How Does PITI Affect DTI?
Lenders put the full qualifying housing payment, which can exceed basic PITI, into your DTI.
Does Paying Extra Principal Lower PITI?
No. Extra payments cut your balance and total interest, but the required payment stays the same unless you recast, refinance or modify the loan.
Are Property Taxes Always Paid Through Escrow?
No. Some borrowers pay taxes and insurance directly instead of through their servicer.
