Your monthly mortgage cost can be higher than the amount shown for principal and interest alone. Depending on your loan and how you pay property expenses, the amount you budget for housing may also include property taxes, homeowners insurance, and mortgage insurance. This guide explains each part so you can compare the full cost—not just the loan payment.
What is usually included in a mortgage payment?
A common starting point is PITI: principal, interest, property taxes, and homeowners insurance. Mortgage insurance may be added when required. Taxes and insurance may be collected through an escrow account or paid directly by the homeowner, depending on the loan arrangement.
Principal and Interest
Principal is the amount you borrow and gradually repay. Each scheduled payment reduces the outstanding balance by the principal portion. Interest is the charge for borrowing the money. For a typical fully amortizing fixed-rate mortgage, the combined principal-and-interest amount is calculated from the loan balance, interest rate, and term. Early in the loan, a larger share of each payment generally goes to interest; as the balance declines, more goes to principal.
For a fixed-rate loan with regular scheduled payments, principal and interest generally stay level. The split between principal and interest changes over time. An adjustable-rate mortgage can behave differently because its rate may change according to the loan terms. See the CFPB explanation of mortgage payment calculations.
Property Taxes
Property taxes are assessed by local or other taxing authorities and are not interest charged by the lender. The amount depends on the property's taxable value, local tax rates, exemptions, and applicable assessments. A lender or mortgage servicer may collect a monthly amount into an escrow account and pay the tax bill when it comes due. If your mortgage does not use escrow, you may need to pay the tax authority directly.
For an initial monthly estimate, divide the annual tax amount you expect to pay by 12. This is a budgeting calculation—not a guarantee of your future bill. Tax amounts can change, so use a current estimate from the relevant local authority or a reliable property-specific source. The CFPB explains how escrow accounts work.
Homeowners Insurance
Homeowners insurance is a separate cost of owning a home. A policy may help cover certain losses to the home and personal property, subject to its coverage, exclusions, deductibles, and limits. Mortgage lenders commonly require borrowers to maintain property insurance as a condition of the loan. The annual premium may be divided by 12 for a monthly budget estimate and may be collected through escrow, but the homeowner should confirm the actual premium and payment arrangement with the insurer and servicer.
Insurance premiums can change at renewal. If insurance is paid through escrow, a premium change can affect the escrow amount and therefore the total payment sent to the servicer.
Private Mortgage Insurance (PMI)
Private mortgage insurance is generally associated with conventional mortgages when the down payment is below 20% of the home's purchase price, although the actual requirement depends on the loan and lender. PMI protects the lender—not the borrower—against certain losses if the borrower does not repay the loan. It adds to the borrower's cost and is different from homeowners insurance.
Do not assume every loan uses the same mortgage-insurance rules or monthly premium. Ask the lender whether mortgage insurance applies, what it costs, how it is collected, and when it may end. The CFPB's guide explains what PMI is and why it may be required.
What Does PITI Mean?
PITI stands for Principal, Interest, Taxes, and Insurance. It is a common way to describe four basic components of a mortgage-related monthly payment:
- Principal: the part that repays the amount borrowed.
- Interest: the cost charged for borrowing.
- Taxes: the monthly amount set aside for property taxes, if included in the payment.
- Insurance: usually homeowners insurance in this acronym, if included in the payment.
Mortgage insurance such as PMI may be an additional charge; it is not represented by the “I” in the basic PITI acronym. HOA or condominium fees, utilities, maintenance, and some other ownership costs may also sit outside PITI. The CFPB definition of PITI describes the four basic elements.
How to Estimate Your Monthly Mortgage Cost
- Find the amount you expect to borrow after subtracting your down payment.
- Use the interest rate and loan term offered for the specific loan to estimate principal and interest.
- Estimate annual property taxes and homeowners insurance, then divide each by 12 if you want a monthly budget amount.
- Add any monthly mortgage-insurance premium required by the loan.
- Check whether HOA dues, flood insurance, or other costs apply; add them separately to your household budget.

How Our Mortgage Payment Examples Are Calculated
When we show a principal-and-interest estimate, we use the standard fixed-rate amortization formula with the stated loan amount, annual interest rate, and number of monthly payments. The calculation assumes the rate stays constant for the stated term and rounds the displayed monthly payment to the nearest cent.
These examples are educational illustrations, not rate quotes or loan offers. Unless a page says otherwise, principal and interest do not include property taxes, homeowners insurance, PMI, HOA dues, or other homeownership costs. Those items can materially change the amount a homeowner actually pays each month.

How is a monthly mortgage payment calculated?
For a typical fixed-rate, fully amortizing loan, principal and interest are calculated from the amount borrowed, the periodic interest rate, and the number of monthly payments. Taxes, insurance, and mortgage insurance are added separately when included in the monthly amount.
Do mortgage payments include property taxes?
Sometimes. Many servicers collect property taxes through escrow, but some borrowers pay the local taxing authority directly. Check the Loan Estimate and your loan documents to see which arrangement applies.
