What Is PITI? The 4 Parts of Your Payment

What do the four letters stand for?

The CFPB’s PITI page, last reviewed September 11, 2024, spells the letters out as principal, interest, taxes, and insurance. Principal is the amount you borrowed and still have to pay back. Interest is what the lender charges for lending the money. The insurance in that name is homeowners insurance, not private mortgage insurance. Taxes are the property taxes on the home. The CFPB does not publish a sample dollar amount for any of the four parts. The example further down is a hypothetical illustration that uses round inputs, not a bill from a lender or a county.

Those four parts are not always sent as one check to one place. The CFPB says amounts for property taxes and homeowners insurance may go into an escrow account, if you are required to have one or you choose to have one. The servicer then pays the tax and insurance bills as they come due. What that account is, and what it is not, is on what is escrow. An escrow deposit does not pay the loan down. Principal does.

Principal and interest are the loan. On a fixed-rate loan that fully amortizes, the CFPB says that part of the payment generally stays the same if you pay on time. A balloon loan is the CFPB’s example of a loan that does not work that way. The split inside the payment still changes every month: early payments are mostly interest, and later payments are mostly principal. The total of the two can stay flat while the mix moves. Taxes and insurance are not part of that mix. They are collected alongside it.

What else can be in the monthly payment?

The CFPB’s page on principal and interest versus the total payment, last reviewed August 28, 2023, writes the full monthly payment as principal plus interest plus mortgage insurance, if it applies, plus escrow for homeowners insurance and tax. Mortgage insurance is an extra term in that equation. It is not a fifth letter inside PITI. If the loan has no mortgage insurance, that term is simply absent. A condo, co-op, or homeowners-association fee is usually paid separately, on top of the mortgage payment.

The estimated total is on page 1 of the Loan Estimate, in Projected Payments. The CFPB says many buyers look only at principal and interest and are surprised by the larger total. If one lender collects taxes and insurance in escrow and another does not, the CFPB says to compare the principal-and-interest lines, and still add up the total you would have to pay. The full-payment calculator is built for that addition, using yearly tax and insurance figures you type. It does not look up your tax bill. Mortgage discount points can change the rate, and therefore the principal-and-interest piece. They do not change the tax bill or the homeowners premium.

When mortgage insurance is borrower-paid PMI on a conventional loan, it can end. The dates are on how to remove PMI: a written request when the balance reaches 80 percent of original value, and an automatic stop at 78 percent on the original schedule, if you are current. FHA, VA, and USDA insurance are different. Removing PMI, when the servicer does it, takes that premium off the monthly payment. It does not change principal, interest, taxes, or homeowners insurance.

How do you calculate PITI?

Hypothetical illustration, not a quote and not a market rate. Suppose principal and interest are $1,500 a month, the figure on a Loan Estimate you already have. Suppose property tax is $3,600 a year and homeowners insurance is $1,800 a year. Taxes per month are $3,600 divided by 12, which is $300. Insurance per month is $1,800 divided by 12, which is $150. PITI is $1,500 plus $300 plus $150, which is $1,950 a month. None of those inputs is a national average. Replace each one with the figure on your own disclosure or bill.

If the loan also has mortgage insurance, the CFPB’s total-payment formula adds it on top of that $1,950. This illustration does not include a mortgage-insurance dollar, because the CFPB does not publish one national PMI premium. HOA dues are usually paid separately, so they are not inside the $1,950 either. If you pay them, add them yourself when you decide what the house costs each month. The four PITI letters stay four letters.

You can run the same arithmetic with your own yearly bills. Divide the annual tax by 12. Divide the annual homeowners premium by 12. Add those two monthly pieces to the principal-and-interest payment. That sum is PITI for those inputs. It will not match the servicer’s escrow deposit if the servicer is also collecting a shortage, a cushion, or mortgage insurance. The escrow analysis page is where a shortage is separated from the bills themselves.

Why can the payment change when the rate does not?

The CFPB says principal and interest generally stay the same if you pay on time, unless the loan is a kind that does not work that way, and it gives a balloon loan as the example. The escrow part can change. Its example is a higher home value followed by higher property taxes. A higher homeowners premium is the other common change inside that escrow deposit. Why a premium moved is a separate question, on why homeowners insurance went up. This page does not name an insurer and does not promise a lower premium.

When the escrow math itself changes, the yearly statement is an escrow analysis. A shortage, a surplus, and a higher tax bill are different lines on that statement. The escrow analysis page is where those lines are separated, and the payment explainer is where you can type the old and new figures from a statement you already have. Neither page manufactures a tax rate. A payment that went up by the amount of a shortage is not a higher interest rate. It is the servicer collecting, over time, a bill that the prior deposit did not cover.

In the hypothetical illustration above, a tax bill that rose from $3,600 a year to $4,800 a year would change the monthly tax piece from $300 to $400, because $4,800 divided by 12 is $400. PITI would then be $1,500 plus $400 plus $150, which is $2,050, if principal, interest, and insurance stayed put. That second set of figures is the same kind of round hypothetical, not a forecast. It shows why the escrow line can move while the rate does not. Your county’s bill is the one that counts.

What if there is no escrow on the Loan Estimate?

The CFPB says that if no escrow payment is listed, taxes and insurance are not inside the payment you send the lender. You pay property taxes to the local government and homeowners insurance to the insurer. The bills are still part of the cost of keeping the house. Leaving them off the mortgage payment does not leave them off the household budget. Ask where to get the tax and insurance figures before you treat a principal-and-interest quote as the whole cost.

Many lenders require escrow, and not all do. That is the CFPB’s statement, not a preference for one lender’s setup. If one offer includes escrow and another does not, compare principal and interest so you are not comparing a partial payment with a full one, and still add the tax and insurance bills to the offer that leaves them out. An escrow account also does not pay down principal. Extra principal is a different decision, and it does not shrink the tax bill.

The four PITI pieces stay four pieces: two of them repay the loan, and two of them pay the carrying costs. Mortgage insurance, points, HOA dues, and a shortage payment can sit near those four without becoming part of the name. The sources below are the pages this desk checked for that split. The $1,500, $3,600, $1,800, and $1,950 figures exist only inside the hypothetical illustration. They are not a CFPB sample, and they are not your payment.

Read Projected Payments on page 1 before you compare two offers. The CFPB says the estimated total monthly payment is in that section, and that many buyers look only at principal and interest. If the line includes escrow, the taxes and insurance in the hypothetical illustration are already inside it, in real life, as whatever amounts that lender typed. If the line does not include escrow, add the tax and insurance yourself or you will compare a partial payment with a full one. Mortgage insurance, if the Projected Payments section shows it, is on top of PITI. Points, if you paid them, already did their work by changing the rate that produced the principal-and-interest figure. They will not appear as a fifth monthly line.

A yearly bill and a monthly escrow deposit are the same dollars only after you divide by 12 and only when the servicer is not also collecting a shortage or a cushion. In the hypothetical illustration, $3,600 of tax becomes $300 a month and $1,800 of insurance becomes $150 a month, and those two deposits plus $1,500 of principal and interest are $1,950. A servicer that also collects a shortage would ask for more than $1,950 even though PITI, strictly, is still $1,950. That is why the escrow statement and the PITI sum can disagree without either one being a new interest rate. Bring the statement to the payment explainer if you want the lines separated. Do not add the hypothetical $1,950 to a real shortage.

Homeowners insurance in PITI is the policy on the house. It is not the same charge as PMI, and it is not mortgage insurance on an FHA or USDA loan. Those premiums can be collected with the monthly payment, which is why the CFPB’s total-payment formula names mortgage insurance separately. The insurance letter in PITI is the homeowners policy the CFPB names on its PITI page. If that premium rises, the escrow deposit can rise with it. The page on why homeowners insurance went up is where the reasons for a higher premium are discussed. This page only places that premium in the monthly sum.
