If you’ve noticed an increase in your mortgage payment, you may be wondering why this has happened. Several factors can contribute to an increase in your mortgage payment, and understanding these reasons is essential for homeowners. In this article, we will explore the various factors that can cause your mortgage payment to go up.

Adjustable Interest Rates

Adjustable interest rates are one of the primary reasons why your mortgage payment may increase. If you have an adjustable-rate mortgage (ARM), your interest rate is subject to change over time. These changes are typically tied to an index, such as the U.S. Prime Rate or the London Interbank Offered Rate (LIBOR). When the index rate increases, your mortgage interest rate will also increase, resulting in a higher monthly payment.

Escrow Account Adjustments

Another factor that can cause your mortgage payment to go up is adjustments to your escrow account. An escrow account is used to collect funds for property taxes, homeowners insurance, and sometimes mortgage insurance. If any of these expenses increase, your lender may adjust your escrow payment to ensure there are sufficient funds to cover these costs. Consequently, this adjustment will lead to an increase in your overall mortgage payment.

Changes in Property Taxes

Changes in property taxes can also impact your mortgage payment. Property taxes are determined by local governments and can increase or decrease over time. If your property tax assessment increases, your lender will need to collect more funds through your monthly mortgage payment to cover the higher tax amount. This increase in property taxes will directly contribute to a higher mortgage payment.

Insurance Premium Changes

Similarly, changes in your homeowners insurance premium can affect your mortgage payment. Insurance companies periodically review their rates, and if your premium increases, your lender will adjust your monthly payment accordingly. This adjustment ensures that there are enough funds in your escrow account to cover the higher insurance costs.

Private Mortgage Insurance (PMI)

If you have a conventional loan with a down payment of less than 20%, you are likely required to pay private mortgage insurance (PMI). PMI protects the lender in case of default. As you make mortgage payments and build equity in your home, the loan-to-value ratio decreases. Once your loan-to-value ratio reaches 80%, you can request to cancel PMI. However, until that point, the PMI premium will contribute to your monthly mortgage payment.


In summary, there are several reasons why your mortgage payment may go up. These include adjustable interest rates, adjustments to your escrow account, changes in property taxes, insurance premium changes, and private mortgage insurance. It’s crucial to stay informed about these factors and understand how they can impact your monthly mortgage payment. By being aware of these potential increases, you can better plan and manage your finances as a homeowner.
