Mortgage Payment Breakdown: What’s Included in Your Monthly Payment

Your mortgage payment typically includes principal and interest and may also include property taxes and homeowner’s insurance. In the mortgage industry, this is often referred to as PITI — Principal, Interest, Taxes, and Insurance. If you have less than 20% down payment or home equity, you’ll likely have some form of mortgage insurance as well — unless you qualify for a VA mortgage, which has no monthly mortgage insurance. Some portions of your mortgage payment may change over time.

Principal and Interest

If you have a fixed-rate mortgage — one that amortizes over 30, 20, 15, or 10 years — your principal and interest payment stays the same for the life of the loan. Over time, more of each payment goes toward principal and less toward interest, but the total payment doesn’t change.

If you have an adjustable rate mortgage (ARM) — where the rate is fixed for an initial period such as 5, 7, or 10 years — the principal and interest payment will adjust once the fixed period ends and will continue adjusting according to the loan terms. If you’re considering an ARM, it’s important to fully understand how adjustments work, what your caps are, and what the best and worst-case scenarios look like when the rate changes.

Home equity lines of credit (HELOCs) typically begin as interest-only with a variable rate tied to the prime rate. After the draw period ends, they may convert to a fixed amortized payment or have a balloon payment depending on the terms.

Property Taxes

Property taxes are based on your home’s assessed value. It’s common for assessed values to increase after you purchase — particularly if your sales price was significantly higher than the previous assessment. When levies pass that are tied to property taxes, your taxes increase as well. In Washington State’s higher-growth markets — King, Snohomish, and Pierce Counties in particular — property tax increases have been a regular occurrence.

Plan on your mortgage payment increasing over time due to property tax adjustments. This is one of the most common reasons homeowners are surprised by a payment increase after closing.

Homeowner’s Insurance

Your homeowner’s insurance premium is generally more stable than property taxes but will likely adjust upward over time for inflation and market conditions. If you make changes to your coverage — such as adding earthquake insurance — your premium will change as well. If you add coverage with a high deductible, make sure you have those funds available before you need them.

Mortgage Insurance

There are two main types of mortgage insurance depending on your loan program:

Private Mortgage Insurance (PMI) applies to conventional loans with less than 20% down payment or equity. PMI is included in your monthly payment and will eventually drop off once you reach the required equity threshold. You can request early removal once you have sufficient equity — either through loan paydown or home appreciation — though lenders typically want to see at least two years of payment history before approving an early removal request. A new appraisal confirming current value is usually required.

Government Mortgage Insurance applies to FHA and USDA loans and works differently than PMI:

• FHA loans have both an upfront mortgage insurance premium (UFMIP), which is typically financed into the loan balance, and an annual mortgage insurance premium (MIP) paid monthly. If you put 10% or more down, MIP remains for 11 years. If you put less than 10% down, MIP remains for the life of the loan — the only way to remove it is to refinance into a conventional loan once you have sufficient equity.
• USDA loans have a similar structure — an upfront guarantee fee and an annual fee paid monthly — and the annual fee also remains for the life of the loan.
• VA loans do not have monthly mortgage insurance — one of their most significant financial advantages.

In practice, many borrowers refinance or sell their home before mortgage insurance naturally drops off. If removing mortgage insurance is a goal, it’s worth running the numbers with your loan officer to determine when a refinance would make financial sense.

What Happens When Property Taxes or Insurance Change?

Unless your escrow account has been waived, the portion of your monthly payment for property taxes and homeowner’s insurance goes into a lender-managed escrow reserve account. The lender holds these funds and pays your insurance premium annually and your property taxes twice a year — first half and second half.

If your taxes or insurance increase and there aren’t enough funds in the reserve account, your servicer will notify you of the shortage and your options — typically a lump sum payment to cover the shortage, an increase to your monthly payment, or both. See my post on why mortgage payments go up for a full explanation of how escrow shortages work.

The reverse can also happen — if your reserve account has too large a surplus, federal law limits how much cushion a servicer can hold. In that case, they’ll send you a refund check or reduce your monthly payment temporarily.

The Bottom Line

Understanding what makes up your mortgage payment — and what can change over time — puts you in a much stronger position as a homeowner. If you have questions about your current mortgage payment or want to understand what your payment would look like on a new purchase or refinance, I’m happy to walk through the numbers with you.
