PITI stands for Principal, Interest, Taxes, and Insurance — it’s your total monthly housing payment, and it’s the number lenders actually care about when deciding how much house you can afford. Most first-time buyers only think about principal and interest, then get blindsided by the tax and insurance portion.

Breaking Down PITI

Principal: The portion that reduces your loan balance. Interest: The lender’s fee for the borrowed money. Taxes: Your annual property tax divided by 12. Insurance: Homeowners insurance premium divided by 12. If you put less than 20% down, add PMI (private mortgage insurance) as a fifth component — sometimes called PITIM.

Lenders use your PITI to calculate your front-end DTI ratio. Most want it below 28-31% of gross income.

Dollar Example

$350,000 loan at 7.00% for 30 years: principal and interest = $2,329/month. Add $375/month in property taxes and $150/month for homeowners insurance. Your PITI is $2,854. With PMI at $140/month (if you put 10% down), you’re at $2,994. That’s $665/month more than the P&I number alone. Use our mortgage calculator to see your full PITI.

Watch Out

Property taxes and insurance aren’t fixed. Taxes can spike after a reassessment, and insurance premiums have climbed 20-30% in many states since 2022. Your PITI in year one might be $200-$400 less than your PITI in year three. Budget for increases.

Also, if your lender collects taxes and insurance through an escrow account, your monthly payment adjusts annually based on an escrow analysis. You might get a pleasant surprise (refund) or an unpleasant one (shortage requiring higher payments). Plan for a 3-5% annual increase in your PITI as a cushion.

Real-World Example

Your lender quotes a monthly payment of $2,450, but your total PITI is actually $3,125. The breakdown: $1,650 principal and interest, $375 property taxes (escrowed monthly), $150 homeowners insurance (escrowed monthly), and $175 PMI. If you are in a flood zone, add another $200/month for flood insurance. Lenders use your total PITI (including PMI and flood insurance) when calculating your DTI ratio. Many first-time buyers focus only on the principal and interest number and are surprised when escrow analysis adds $500-$1,000/month to their actual payment.

Frequently Asked Questions

What percentage of my income should PITI be?

The traditional guideline is no more than 28% of gross monthly income for PITI. Lenders will approve up to 43-50% total DTI, but that doesn’t mean you should max out. A comfortable PITI is one that still leaves room for savings, retirement contributions, and life’s surprises. Check your numbers with our DTI calculator.

Why did my PITI payment increase?

The P and I portions are fixed on a fixed-rate mortgage, but T and I (taxes and insurance) change. Property taxes can increase when your county reassesses values. Insurance premiums rise with rebuilding costs and claims history. Your lender adjusts your escrow payment annually, which changes your total PITI.

How do lenders use PITI to qualify me?

Lenders divide your total PITI by your gross monthly income to calculate your front-end DTI ratio, which most programs cap at 28-31%. They also add your other debts to calculate back-end DTI. If your PITI alone exceeds 28% of gross income, some loan programs may not be available to you.
