What Is PITI?
PITI stands for principal, interest, taxes and insurance - the four parts of a typical monthly mortgage payment. Lenders use the full PITI amount, plus any mortgage insurance and HOA dues, to judge affordability, so property taxes and insurance can change how much home a buyer qualifies for.
PITI in plain English
PITI is shorthand for the four things most monthly mortgage payments cover: principal (paying down the loan), interest (the lender's charge), property taxes and homeowners insurance.
Taxes and insurance are often collected through an escrow account and paid by the servicer when the bills come due. Mortgage insurance and HOA dues are not in the acronym but are part of the housing cost lenders count.
Advanced explanation
PITI - principal, interest, property taxes and homeowners insurance - is the core monthly housing payment used in qualifying ratios. Lenders also add mortgage insurance and HOA dues when calculating the housing expense for debt-to-income purposes.
Formula
PITI = Principal + Interest + Property Taxes + Homeowners Insurance- Principal
- The part of the payment that reduces the loan balance.
- Interest
- The lender's charge for the month on the remaining balance.
- Property Taxes
- One-twelfth of the annual property tax bill.
- Homeowners Insurance
- One-twelfth of the annual homeowners insurance premium.
Add mortgage insurance and HOA dues to get the full monthly housing cost lenders use.
Example
A $2,000 monthly mortgage payment might break down as $1,400 principal & interest, $400 property taxes, and $200 homeowners insurance.

| Component | Type | Monthly | Yearly |
|---|---|---|---|
| Principal & interest | Financing (calculated) | $2,275 | $27,305 |
| Mortgage insurance | Financing (calculated) | $180 | $2,160 |
| Property tax (estimate) | Ownership (estimate) | $400 | $4,800 |
| Homeowners insurance (estimate) | Ownership (estimate) | $150 | $1,800 |
Formula
Principal & interest = Loan × r ÷ (1 − (1 + r)^−n), r = annual rate ÷ 12, n = years × 12Mortgage insurance = Loan × PMI rate ÷ 12 (conventional loan, under 20% down)Assumptions
- Fixed-rate loan; the rate stays the same for the whole term.
- Mortgage insurance applies to conventional loans with less than 20% down and stops once the loan reaches 78% of the original value.
- Property tax, insurance and HOA dues vary by location and change over time.
Why it matters
Lenders qualify borrowers using the full PITI payment, not just principal and interest — so taxes and insurance can meaningfully affect how much home you can afford.
Taxes and insurance can add a large share to the principal-and-interest payment, so two homes at the same price can have very different monthly costs - and qualify a buyer for different loan amounts.
What it means for you
How does it affect my budget?
Budget from PITI plus mortgage insurance, HOA dues and maintenance - not from the principal-and-interest figure in rate advertisements.
What buyers should know
Ask for the current tax bill and an insurance quote before you make an offer.
Common mistakes
- Comparing homes by price and principal-and-interest only.
- Using the seller's current tax bill when a sale may change the assessment.
- Forgetting that taxes and insurance can rise even on a fixed-rate loan.
Compare and common questions
PITI: frequently asked questions
Is PITI the same as my mortgage payment?
Usually, if your loan has an escrow account. Your statement may also include mortgage insurance; HOA dues are normally paid separately to the association.
Why do lenders use PITI instead of just principal and interest?
Because taxes and insurance are unavoidable costs of owning the home. Lenders add them to measure whether your income can carry the full housing payment.
Can PITI change after I buy?
Yes. Principal and interest are fixed on a fixed-rate loan, but property taxes and insurance premiums change, and the escrow portion of the payment changes with them.
