PITI Calculator

About the PITI Calculator

When people talk about their "mortgage payment," they usually mean the total PITI: Principal, Interest, Taxes, and Insurance. The principal and interest (P&I) portion pays down the loan, while property taxes and homeowner's insurance are typically collected through an escrow account and paid on your behalf by the lender. If your down payment is below 20%, lenders also require private mortgage insurance (PMI), which adds yet another component.

This PITI calculator gives you the complete monthly housing cost picture. Enter the loan amount, rate, and term for P&I; add annual property taxes and insurance premiums; and if applicable, include PMI. The tool breaks down each component so you can see exactly where your money goes each month.

Knowing your full PITI is essential for budgeting because P&I alone can understate your true housing cost by 20–40%. Lenders also use PITI (not just P&I) when calculating your debt-to-income ratios, so this is the number that determines whether you qualify for the loan.

When This Page Helps

Online mortgage calculators often show only P&I, leaving buyers shocked when their actual payment is hundreds of dollars higher. This calculator prevents that surprise by combining all four (or five) components into one accurate total. It's especially useful for comparing properties in different tax jurisdictions or with different insurance requirements, where the P&I may be identical but the PITI differs significantly.

How to Use the Inputs

1. Enter the home purchase price and your down payment percentage to compute the loan amount.
2. Set the annual interest rate and loan term for the P&I calculation.
3. Input the annual property tax amount or rate for the property.
4. Enter the annual homeowner's insurance premium.
5. If your down payment is below 20%, enter the PMI rate (typically 0.5–1.0% of loan annually).
6. Review each component and the total monthly PITI payment.

Example Calculation

Tips & Best Practices

• Escrow accounts collect tax and insurance monthly so you don't face large lump-sum bills.
• PMI can be removed once your loan-to-value reaches 80% through payments or appreciation.
• Property taxes can change annually — budget for potential increases of 2–3% per year.
• Insurance costs vary widely by location; hurricane and flood zones can double or triple premiums.
• Compare PITI, not just P&I, when evaluating homes in different cities or tax jurisdictions.

Breaking Down Each PITI Component

Principal is the portion of each payment that reduces your loan balance. Interest is the cost of borrowing, calculated on the remaining balance. In early years, most of each payment is interest; by the end, most is principal. Property taxes fund local government services and are based on assessed property value. Homeowner's insurance protects against damage and liability.

Why PITI Matters for Qualification

Lenders calculate your front-end DTI using PITI (plus PMI and HOA), not just P&I. Two borrowers with the same income and loan amount might qualify at very different price points if one lives in a high-tax state and the other in a low-tax state. Always account for local costs when budgeting.

PMI: The Temporary Fifth Component

PMI exists to protect the lender when you put less than 20% down. Once your equity reaches 20% (through payments or appreciation), you can request cancellation. At 22% equity, the lender must cancel automatically. Some buyers choose lender-paid PMI, which is rolled into a slightly higher interest rate.

Frequently Asked Questions

• What does PITI stand for?

  PITI stands for Principal, Interest, Taxes, and Insurance. It represents the four core components of a monthly mortgage payment. Lenders and financial advisors use PITI as the standard measure of housing cost when evaluating affordability and debt-to-income ratios.

• Is PMI included in PITI?

  Technically PITI refers to four components, but when lenders calculate DTI they include PMI as well, so it's effectively part of your qualifying payment. This calculator includes PMI as a fifth component when applicable, giving you the true total housing cost.

• How is the escrow portion calculated?

  Your servicer estimates the annual property tax and insurance bills, divides by 12, and adds that amount to each monthly payment. Once a year they reconcile: if taxes or insurance changed, your escrow amount adjusts accordingly, potentially raising or lowering your total payment.

• Can I waive escrow and pay taxes/insurance myself?

  Some lenders allow escrow waivers, usually requiring 20%+ equity and a small rate bump (0.125–0.25%). While this gives you control of the funds, you must discipline yourself to save for lump-sum tax and insurance payments that can be thousands of dollars.

• How much does PMI typically cost?

  PMI rates range from 0.3% to 1.5% of the loan amount annually, depending on your credit score, loan-to-value ratio, and loan type. For a $300,000 loan, that's $75–$375 per month. Higher credit scores and larger down payments earn the lowest PMI rates.

• Why is my actual payment different from the P&I amount I calculated?

  The difference is almost always the escrow components: property tax, homeowner's insurance, and possibly PMI. On a $320,000 loan, these can add $500–$800/month beyond the P&I portion, which is why PITI is the only meaningful number for budgeting.
