Principal, interest, tax, insurance: the whole payment.
Total monthly housing payment
Estimates for planning only, not financial advice.
PITI is the full monthly cost of owning a home with a mortgage: principal, interest, property tax, and homeowners insurance. A $1,500 principal-and-interest payment plus $400 of tax and $150 of insurance is $2,050 PITI. Lenders qualify you on PITI, not just the loan payment, because taxes and insurance are just as mandatory as the mortgage.
How to Use This Calculator
Enter the four components as monthly amounts. If you know the loan terms instead of the P and I payment, compute it first, then add tax and insurance. Include PMI if your down payment is under 20 percent.
Enter principal and interest from your loan quote or amortization schedule.
Add monthly property tax (annual bill divided by 12) and homeowners insurance.
Read total PITI and test it against income. Our mortgage payment calculator builds the P and I piece.
The PITI Formula
Taxes and insurance are usually escrowed: the lender collects one-twelfth each month and pays the bills when due. That smoothing is convenient until reassessment or premium hikes raise the escrow and your payment jumps. The P and I never changes on a fixed loan; the T and I change constantly.
Worked Example
Principal and interest $1,500, property tax $400, insurance $150: PITI is $2,050 a month, $24,600 a year. Tax is 19.5 percent of the payment, insurance 7.3 percent. On a $90,000 household income, PITI is 27.3 percent of gross, inside the 28 percent front-end guideline most lenders use.
Reading Your Result
The 28/36 rule is the standard yardstick: PITI under 28 percent of gross monthly income, all debts under 36 percent. But taxes vary wildly by state: the same house price in New Jersey can carry triple the tax of Texas, which is why PITI shopping matters more than price shopping across state lines.
My rule: budget on PITI plus 1 percent of the home's value per year for maintenance, because the mortgage servicer collects PITI but nobody collects the roof fund. A $400,000 home needs roughly $4,000 a year in upkeep reserves. Skip that and the first big repair goes on a credit card at 20 percent. For the tax deduction side of ownership, our income tax calculator shows what mortgage interest saves you.
First-time buyers consistently underestimate the T and I. A $1,800 principal-and-interest payment can easily become $2,500 PITI once property tax and insurance join, and lenders qualify you on the full number. When comparing listings, always ask for the tax history and get an insurance quote before falling in love with the kitchen. The PITI is the real monthly cost; everything else is marketing.
Escrow is where PITI gets lumpy. Your lender collects one-twelfth of the annual tax and insurance each month, then pays the bills when due. Once a year they reconcile: if taxes rose, you get a shortage notice and next year's payment jumps to cover both the higher bills and the shortfall. That double hit is why fixed-rate borrowers still see their "fixed" payment change.

Frequently Asked Questions
What does PITI stand for?
Principal, Interest, Taxes (property tax), and Insurance (homeowners). It is the complete monthly payment of a mortgaged home, and the number lenders use to qualify borrowers. Lenders quote it as one number because escrow merges all four into a single monthly draft.
How is PITI different from the mortgage payment?
The mortgage payment is usually quoted as principal and interest only. PITI adds property tax and homeowners insurance, which are equally mandatory. The gap between P and I and PITI surprises many first-time buyers. On a $2,000 P&I payment, taxes and insurance can easily add $600 more: always ask for PITI.
What is a good PITI to income ratio?
Lenders typically want PITI at or under 28 percent of gross monthly income (the front-end ratio) and all debts under 36 percent (back-end). Some loan programs allow higher with compensating strengths like big reserves. VA loans allow higher ratios with residual income tests: the 28 percent rule bends for veterans.
Why did my PITI go up on a fixed-rate mortgage?
Property taxes or insurance rose, increasing the escrow portion. The principal and interest cannot change on a fixed loan, but the T and I reprice yearly. Escrow shortages get spread across the next twelve payments, amplifying the jump. Escrow analyses happen yearly: a shortage gets divided by 12 and added to next year's payment.
Is PMI part of PITI?
Often quoted as PITI plus PMI, or PITIA. PMI is required below 20 percent down on conventional loans and behaves like a fifth component. Include it in affordability math until it drops off. FHA loans call it MIP instead of PMI, but it plays the same fifth-wheel role.
How do I estimate property tax for PITI?
Multiply the home's assessed value by the local tax rate, then divide by 12. New purchases often get reassessed to the sale price, so use the purchase price times the rate rather than the seller's old bill. Appeal deadlines are strict and annual: miss the window and you wait a full year.
Does PITI include HOA dues?
Not in the acronym, but lenders and budgets should include them. HOA dues are mandatory and can rival the tax portion in condos. Add them to PITI mentally for the true monthly cost. Special assessments are the HOA world's nasty surprise: budget a buffer for them.
Can I reduce my PITI?
Refinance to cut principal and interest, appeal an inflated property assessment to cut taxes, or shop insurance annually. The P and I is the biggest lever; tax appeals are the most overlooked one. Shopping insurance every two years typically saves 10 to 20 percent: loyalty rarely pays.
What is escrow and how does it relate to PITI?
Escrow is the account where your lender holds the tax and insurance portions of PITI, paying the bills when due. You fund it monthly as part of PITI plus a small cushion the law allows. The cushion is capped by RESPA at two months of escrow payments: lenders cannot pad it endlessly.
Should I budget beyond PITI?
Yes. Plan roughly 1 percent of the home's value per year for maintenance plus utilities. PITI is the lender's number; the owner's number is bigger, and the difference is what breaks unprepared budgets. Roofs, HVAC, and appliances fail on their own schedule: the 1 percent rule smooths the lumps.
