What Is Principal, Interest, Taxes, Insurance (PITI)? A Comprehensive Guide

When your mortgage payment comes due every month, it may look like a single bill. But in reality, you’re likely paying four separate things: principal, interest, taxes, and insurance. PITI is an acronym that bundles these four elements together. But in order to better understand where, exactly, your monthly mortgage money is going, we’re going to take PITI apart and explain each element for you.

Understanding PITI

As discussed above, PITI is the acronym for the four basic components of a monthly mortgage payment. PITI includes:

•  Mortgage principal (the amount you borrowed from the bank)

•  Mortgage interest (the amount the bank charges you for the loan)

•Property taxes (levied by the local government)

•  Homeowners insurance (which covers the cost of repairing or replacing your home under certain covered circumstances)

Importance in Mortgage Payments

Together, these amounts add up to your total monthly mortgage payment — though that amount is not the same as your total monthly home expenses, which also include things like utilities and maintenance. (More on that below.)

Breaking down your PITI and calculating each separate component helps you better understand where your money is going each month. During the home-buying process, it helps you narrow your home search to those that are actually affordable on your budget. And later, knowing what does PITI stand for and what numbers comprise the components of your PITI will help you if you need to request a mortgage interest deduction on your taxes.

Breaking Down PITI Components

Principal and interest are paid to your mortgage lender, and include both the money you borrowed and the money the bank is charging you for the service of offering the loan. Keep in mind that the amount of principal versus interest will change over the lifetime of the loan in a process known as amortization. To get a full picture of how that works, try out a mortgage calculator that includes an amortization chart.

Meanwhile, your property taxes and homeowners insurance will likely flow into an escrow account, where funds will be used to pay those bills as they come due. Property taxes are almost always included in your mortgage payment, and if you owe money on your home, you will be required to carry homeowners insurance. (Even if you don’t, buying a policy is a good idea. After all, if you’re like many Americans, your home is likely the single most valuable asset in your portfolio.)

Finally, there are also other components that may be part of your monthly mortgage payment — though not part of your PITI. These include extras like PMI (private mortgage insurance) or HOA fees. Not every home purchase will come with these payments, but if you make a down payment of less than 20%, some sort of mortgage insurance is usually inevitable.

How PITI Affects Home Affordability

PITI in real estate affects home affordability in a pretty straightforward way: Knowing your PITI ahead of time helps you ensure you’re making an offer on a house that’s truly within your budget. Knowing the cost of a home is one thing, but knowing how much the mortgage will actually take out of your account each month is another. One important rule of thumb: Most lenders prefer that your PITI is less than or equal to 28% of your gross (pre-tax) monthly income.

Fortunately, there are some things you can do to lower your interest rate — which lowers your overall PITI. By keeping your debt-to-income ratio (DTI) low and maintaining a good credit score, you can help ensure you get the lowest interest rates possible, which may expand your home-buying power by qualifying you for a lower rate, no matter the purchase price.

Calculating Your PITI

These days, the easiest way to calculate your PITI is by using an online mortgage calculator with taxes. You’ll need to estimate the home’s annual property taxes based on records kept by your county, and add the insurance premium quoted to you into the mix.

Keep in mind, however, that PITI can (and likely will) change over time as both tax rates and your insurance premiums change each year. Although a fixed-rate mortgage keeps your “PI” static, the “T” and “I” may change your overall monthly mortgage payment over the course of its term. To ensure long-term affordability, consider how increases in each of these categories might work with your budget.

PITI vs. Non-PITI Expenses

As discussed above, PITI doesn’t cover the whole range of homeownership expenses. Along with additional extras like homeowners association (HOA) fees and mortgage insurance, owning a home also means paying monthly utilities as well as any regular repair and maintenance costs.

Those costs can add up, especially if you’re not expecting them. One common rule of thumb is to set aside 1% of your home’s value for repairs each year, with exact figures depending on where you live. (In other words, in some expensive states, like Hawaii, California, and New York, repair costs may be even higher.)

Strategies to Manage and Reduce PITI

Keeping your PITI low keeps your housing expenses low, and while some parts of your mortgage may seem set in stone, others are more negotiable.

For example, did you know that you can challenge property tax assessments (that determine the amount of “T” in your PITI)? Once your home is valuated, if you disagree with the findings, you may reach out to your county or local governance to challenge them. Doing so may lower your taxable property value. (Be warned, however, that if the current valuation does not include recent renovations or, say, a new outbuilding, the taxable value could actually rise.)

Additionally, shopping around for insurance can go a long way toward lowering the second “I” in your PITI. Different insurance companies have different proprietary algorithms and therefore different rates for similar coverage. Additionally, you can play with how much coverage you buy — but use caution before skimping on protecting your home.

Finally, if you already have a home mortgage loan but your creditworthiness profile has substantially improved (and market interest rates are lower than they were when you took out the loan in the first place), refinancing may serve to substantially lower the “P” and initial “I” in your PITI. Remember, though, that you’ll pay closing costs again, so factor in that expense before deciding this is the right financial move for your situation.

The Takeaway

The acronym PITI describes the four most basic elements of a monthly mortgage payment — but they’re far from the only costs associated with homeownership. Still, understanding PITI can help you find a home that’s within a reasonable purchase price range in the short term — and taking strategic steps to reduce your PITI can help you keep your costs low for years to come.

FAQ

How does PITI change over the life of the loan?

If you have a fixed-rate mortgage, your principal and interest payments will always amount to the same total — though the ratio of how much of those funds go toward interest versus principal will shift over the lifetime of the loan in a process known as amortization. Your property tax rate and insurance rate may change over time based on the valuation of your home, changes in the local tax code, and insurance premium changes (or a change in insurers). Thus, your monthly housing cost could shift, and even increase, over time, even if the loan is fixed-rate.

Can I pay property taxes and insurance separately from my mortgage?

In most cases, property taxes and homeowners insurance are paid together with the mortgage, and the funds go into an escrow account where they pay their respective bills as they come due. However, it is possible to secure an escrow waiver from your home lender, which would allow you to pay these expenses separately.

How does PITI affect my ability to qualify for a mortgage?

Lenders calculate your PITI before approving your mortgage application — and if your PITI is too high, you might not get approved. Generally speaking, lenders like to see your PITI equal to or less than 28% of your gross monthly income, though some lenders may approve you if your PITI is slightly higher.

What happens if I can’t afford the full PITI payment?

If your financial circumstances change and you can no longer afford to pay your mortgage, your first move should be to contact your lender. They may be able to negotiate or offer a mortgage assistance service. Talking to a U.S. Department of Housing and Urban Development foreclosure avoidance counselor could also help — but simply allowing your loan to fall into default could lead to home foreclosure.
