What does a monthly mortgage payment include? PITI explained

Your monthly mortgage payment is made up of four components known as PITI: principal, interest, taxes and insurance. Depending on your loan and property type, it may also include private mortgage insurance (PMI) and homeowners association (HOA) fees. Together, these numbers determine what you actually owe every month.

Your loan estimate spells out your mortgage payment, and your closing disclosure confirms it. By closing day, you know exactly what you owe your lender each month. The real surprise comes later, when you receive your first annual escrow analysis. That's when many homeowners discover their monthly payment has changed, even though their interest rate has stayed exactly the same.

Understanding PITI and that two of the four components aren't fixed will help you prepare for those sticker shocks as a new homeowner. Here's how PITI works and why your escrow analysis matters more than many first-time homebuyers realize.

Why understanding PITI matters

Your mortgage payment includes four key elements known as PITI: principal, interest, taxes and insurance. You make a single home loan payment each month, but lenders earmark different amounts for different payments. This number matters before you even make an offer. Lenders use PITI to calculate your DTI ratio, or the percentage of your monthly gross income that goes toward your monthly debts, including your new mortgage. While the principal and interest portion of your mortgage payment goes to your lender, the taxes and insurance payments are typically put into an escrow account. Your lender pulls from this account to make annual payments for your home insurance premium and property tax bill on your behalf.

Breaking down each part of PITI

Here's what each element of PITI covers and how it factors into how much house you can afford.

Principal

Principal is the total amount borrowed. You repay it over the life of the loan through monthly payments. Each payment chips away at your total balance, slowly at first, then faster later in the loan.

Early on, most of your mortgage payment goes toward interest, not the principal. This may feel discouraging initially, but every dollar toward principal is a dollar of equity you now own.

Interest

Interest is the price you pay to borrow money, expressed as an annual percentage of your principal. Fixed-rate loans lock in that percentage for the life of the loan. Adjustable-rate mortgages (ARMs) hold steady for an initial period, then can fluctuate with market conditions for the remainder of the loan term.

A lower interest rate doesn't automatically mean a lower total payment. Two similarly priced homes can carry different tax bills or insurance costs, and the one with the “better” rate could still cost more per month once those are added in.

Taxes

Your city or county bills for property taxes annually. Your lender divides that amount by 12 and collects it as part of your monthly payment, holding it in escrow until the bill is due.

Your taxes aren't fixed for the life of your loan even if you have a fixed rate. A property reassessment or local tax increase can bump up your monthly payment.

Insurance

Homeowners insurance covers damage to the home's structure and personal property, as well as liability protection. Like taxes, most lenders collect this payment monthly through escrow and pay the annual premium for you.

Additionally, if the property is in a federally designated flood zone, you'll pay mandatory flood insurance, which is another line item to factor in.

Mortgage insurance

On a conventional loan, a down payment below 20% means you'll also pay private mortgage insurance (PMI). PMI typically costs between 0.5% and 1.5% of the loan amount per year but may be removed once certain equity requirements are met.

FHA loans have two types of mortgage insurance premiums (MIP): upfront and annual. FHA upfront MIP is 1.75% of the loan amount, while annual MIP rates vary based on the loan amount, down payment and term. The annual MIP typically lasts for the life of the loan unless you refinance into a conventional mortgage.

What else might appear in your monthly payment?

If your home is in a homeowners association (HOA), you'll also pay dues. While you typically pay HOA fees directly to the HOA, lenders consider them in their DTI calculation.

PITI doesn't include ongoing utilities, maintenance or repair costs, and lenders don't factor these costs into your DTI ratio. You'll also want to budget for landscaping, seasonal upkeep and other routine homeownership expenses separately.

How lenders use PITI to decide what you can borrow

Lenders use two DTI ratios to determine if you can repay your mortgage. The front-end ratio divides your PITI by your gross monthly income, and lenders prefer this at or below 28%. The back-end ratio adds PITI to all your other debts, such as credit cards, vehicle payments and student loans, then divides the sum by your gross monthly income. Most lenders prefer the back-end ratio to stay at or below 36%, but some loan programs allow a DTI as high as 50%. Make sure the estimated mortgage payment fits your long-term goals and budget once you add in other bills so you don't spread yourself too thin.

How to estimate your PITI before making an offer

Here's a step-by-step guide to building your own PITI estimate, using a $350,000 home with a 10% down payment as an example.

1. Start with your loan amount. This is the home price minus the down payment: $350,000 - $35,000 = $315,000 loan.
2. Calculate principal and interest. You use your estimated rate and loan term to calculate $1,900 a month.
3. Estimate property taxes. Your local tax rate divided by 12 gives you $350 per month.
4. Get homeowners insurance quotes. Dividing the annual premium by 12 yields $120 per month.
5. Add PMI. With 10% down, PMI applies here, for an estimated $175 a month.
6. Add HOA fees, if applicable. This isn't part of escrow but is part of DTI at $50 a month.
7. Add it all up. $1,900 + $350 + $120 + $175 + $50 = $2,595 per month. This is your true estimated housing cost.

Frequently asked questions

Can my monthly mortgage payment increase even if I have a fixed-rate loan?

Yes, your monthly mortgage payment can increase, even with a fixed-rate loan. The taxes and insurance portion of your payment can go up over time, pushing your overall mortgage payment higher.

What is an escrow account and why do I need one?

Many lenders require an escrow account to pay your property taxes and home and mortgage insurance premiums. Lenders collect these payments, hold them in escrow and pay these bills for you.

When can I stop paying PMI?

For many conventional loans, PMI may be removed once you meet lender requirements related to home equity. FHA mortgage insurance rules differ and depend on factors such as the loan term and down payment amount.
