Section 01
The mortgage payment you see in a lender quote may not be the full amount you pay each month.
Many buyers focus only on principal and interest and underestimate their true monthly housing cost. PITI helps you see the bigger picture by including taxes, insurance, and PMI when applicable.
In this guide, you’ll learn how to calculate PITI in five simple steps using a $300,000 home example.
Important: The examples below are for educational and illustrative purposes only. Actual payments depend on many things. They include your loan amount and interest rate. Your credit profile is important too. Property location, insurance costs, taxes, and lender rules matter as well.
Section 02
What Does PITI Mean in a Mortgage?
PITI stands for:
- Principal: The amount that goes toward reducing your loan balance.
- Interest: The cost you pay to borrow money from your lender.
- Taxes: Your property taxes, usually collected monthly through an escrow account.
- Insurance: Your homeowners insurance premium.
Together, these four costs make up your estimated monthly housing payment.
Lenders check PITI to see if you can afford a mortgage. Your monthly housing payment is part of your debt-to-income ratio (DTI). A higher PITI payment can affect how much home you may qualify for.
While PITI traditionally includes principal, interest, taxes, and insurance, your total monthly housing payment may also include PMI, HOA dues, or other required costs if their down payment is below 20% on a conventional loan.
Section 03
Step 1: Calculate Your Principal and Interest Payment
When a lender gives you a mortgage estimate, principal and interest are often the first numbers you see. Your monthly payment depends on how much you borrow, the interest rate on your loan, and how long you take to repay it.
Example: You purchase a $300,000 home with 5% down.
- Home price: $300,000
- Down payment: $15,000
- Loan amount: $285,000
- Loan term: 30 years
- Interest rate: 6.0%
Your estimated principal and interest payment would be about: $1,709 per month
This is only an illustration. Actual rates and payments vary by lender, borrower qualifications, and market conditions.
Section 04
Step 2: Estimate Your Property Taxes
Property taxes affect how much you pay each month and can make your total housing cost higher than you expect. The amount varies depending on where the home is located, your county’s tax rate, and the property’s assessed value.
A rough estimate can help you understand what to budget for before you buy.
For illustration, let’s assume a 1.1% annual property tax rate:
| Home Value | Annual Property Tax (1.1%) | Monthly Property Tax |
|---|---|---|
| $300,000 | $3,300 | $275 |
This is only an example for calculation purposes. Your actual property tax rate depends on your location, county assessment, and local tax rules.
Section 05
Step 3: Estimate Your Homeowner's Insurance
Homeowners insurance is usually included in your monthly mortgage payment through escrow. Your premium depends on your location, coverage level, deductible, and insurer.
Using an estimated annual premium of $1,600:
$1,600 ÷ 12 = $133 a month.
This is an illustrative national estimate. Actual homeowner’s insurance premiums vary by location, coverage level, and insurer, and do not constitute an offer of credit.
Section 06
Step 4: Add PMI If Your Down Payment Is Below 20%
If you put less than 20% down on a conventional loan, you may need to pay private mortgage insurance (PMI). PMI protects the lender if you stop making payments on a loan with less equity, but it does not protect your home or reduce your loan balance. Your PMI cost can vary based on your credit profile, down payment, loan type, and the amount you borrow.
Example:
| Down Payment | Loan Amount | Estimated PMI | Monthly PMI |
|---|---|---|---|
| 5% | $285,000 | 0.8% annually | About $190 |
| 10% | $270,000 | 0.5% annually | About $113 |
| 20%+ | Varies | No PMI | $0 |
These figures are examples only. Actual PMI rates vary based on borrower and loan factors.
Section 07
Step 5: Add It All Together for Your Total PITI
Now stack all four pieces on top of each other:
| Cost | Monthly |
|---|---|
| Mortgage payment | $1,709 |
| Property taxes | +$275 |
| Insurance | +$133 |
| PMI | +$190 |
| Estimated PITI | $2,307 |
In this example:
- Principal and interest: $1,709
- Total housing payment: $2,307
The difference is $598 per month because taxes, insurance, and PMI are added on top of the loan payment.
This is why looking only at principal and interest can give an incomplete picture of your monthly housing cost.
Section 08
Frequently Asked Questions
Does PITI include HOA dues?
No. PITI covers principal, interest, taxes, and insurance only. If your home has a homeowners association, you pay extra monthly dues. These dues are on top of PITI. Most lenders include them in your debt-to-income ratio. This helps decide how much you can qualify for.
How do I estimate property taxes if I don’t know my local rate?
The most reliable source is the seller’s most recent tax bill, which your agent or listing can usually provide. Your county assessor’s website is a good backup. The 1.1% national average mentioned here is just a rough guide. Your local rate might be much higher or lower than this figure.
How much lower is PITI with 10% down instead of 5%, on the same $300,000 home?
Putting 10% down instead of 5% lowers your loan amount, your principal and interest payment, and your PMI rate all at once. On this example, that combination brings total PITI down from $2,307 to about $2,140, a difference of roughly $167 a month.
These figures are illustrative estimates only and do not constitute an offer of credit. Actual payments depend on your rate, credit profile, and lender.

Once you know your real PITI, you know your real budget, not just the number that made a home listing look affordable.
