Does Your Mortgage Go Up Every Year?

Does your mortgage payment always stay the same? Uncover the various components that can cause it to change annually.

Many homeowners wonder if their mortgage payment will increase annually. While the principal and interest portion of a fixed-rate mortgage typically remains stable, other elements contributing to the total monthly payment can change. For adjustable-rate mortgages, the interest portion itself is subject to periodic adjustments. Understanding the different components of a mortgage payment and the factors influencing them provides clarity on potential fluctuations.

Understanding Mortgage Interest Rates: Fixed vs. Adjustable

A fixed-rate mortgage offers predictability because its interest rate remains the same for the entire duration of the loan. This means the portion of your monthly payment allocated to principal and interest will not change over time, providing stability in your housing budget.

In contrast, an adjustable-rate mortgage (ARM) features an interest rate that can change periodically after an initial fixed-rate period. Common ARM structures, such as a 5/1 ARM, indicate that the interest rate is fixed for the first five years, then adjusts annually thereafter. These adjustments are based on a chosen financial index, such as the Secured Overnight Financing Rate (SOFR) or the Constant Maturity Treasury (CMT), plus a predetermined margin set by the lender.

When an ARM’s interest rate adjusts, the principal and interest portion of the monthly payment can either increase or decrease, reflecting current market conditions. ARMs include interest rate caps that limit how much the rate can change at each adjustment period and over the life of the loan. These caps prevent extreme payment fluctuations, but significant changes are still possible depending on the movement of the underlying index.

Beyond Principal and Interest: The Full Mortgage Payment

The total monthly mortgage payment often encompasses more than just the principal and interest (P&I) repayment. This broader payment structure is commonly referred to by the acronym PITI, which stands for Principal, Interest, Taxes, and Insurance. Each of these additional components can fluctuate independently of the loan’s interest rate.

Property taxes represent levies assessed by local government entities based on the value of your home. These taxes are not fixed and can be reassessed periodically, annually, leading to changes in the amount due. Homeowners insurance provides coverage for your property against damage from events like fires or natural disasters and is a requirement from lenders. Insurance premiums can vary due to factors such as inflation, increased risk in the area, or the age and characteristics of the home.

Many mortgages include mortgage insurance, such as Private Mortgage Insurance (PMI) for conventional loans or a Mortgage Insurance Premium (MIP) for FHA loans. PMI is required when a borrower makes a down payment of less than 20% of the home’s purchase price. MIP is required for most FHA loans and may last for the life of the loan.

Lenders manage the collection and payment of property taxes and homeowners insurance premiums through an escrow account. Funds for these expenses are collected as part of your monthly mortgage payment and held in this account. The lender conducts an annual escrow analysis to ensure sufficient funds are being collected, and this analysis can lead to adjustments in your monthly payment to cover any shortfalls or surpluses.

Factors That Can Change Your Monthly Mortgage Payment

For those with an adjustable-rate mortgage, the most direct cause of payment changes is the periodic reset of the interest rate. The rate adjusts based on a specified index and margin, causing the principal and interest portion of the payment to rise or fall with market interest rates. These changes directly impact the loan’s cost.

Property tax increases can also lead to higher monthly mortgage payments. Local municipalities have the authority to increase property tax rates or reassess property values, which results in a larger tax bill for homeowners. When this occurs, the amount collected for property taxes within your escrow account must increase to cover the new, higher obligation, thereby raising your total monthly payment.

Homeowners insurance premiums are subject to change by insurance providers. These increases can stem from various factors, including a rise in the cost of construction materials and labor for repairs, an increased frequency of natural disasters in your region, or general inflationary pressures. Such premium hikes are then reflected in the escrow portion of your monthly payment.

The annual escrow account adjustment is a common reason for payment fluctuations. Lenders review the actual costs of property taxes and homeowners insurance against the amounts collected in escrow. If actual expenses exceed collected funds, or a shortage needs recovery, the lender increases your monthly escrow contribution to cover the difference and maintain a buffer. Conversely, a significant surplus might result in a refund or a slight reduction in the monthly payment.

For certain loan types, the removal of mortgage insurance can decrease the monthly payment. For conventional loans with Private Mortgage Insurance (PMI), the Homeowners Protection Act of 1998 (HPA) mandates automatic termination of PMI when the loan balance reaches 78% of the original home value. Borrowers can also request cancellation once their equity reaches 20% of the original value. This removal eliminates that specific cost from your monthly obligation.

While not automatic, voluntary actions can also change your monthly payment. Refinancing your mortgage involves taking out a new loan to pay off your existing one, which can lead to a different interest rate or loan term, altering your payment. Similarly, making substantial principal prepayments can shorten the loan term and potentially reduce future interest.
