Common reasons for mortgage payment increases
Most of the time, the reason for your mortgage payment increase isn’t your loan itself; it’s usually all the other stuff that gets bundled in, Julian Merrick, the CEO of SuperTrader, told us. “Property taxes go up. Home insurance costs more. Your lender is the one paying those bills through something called an escrow account. The amount you pay increases as escrow runs low. Because the lender's previous collection was insufficient. And they are now attempting to make up the deficit.”
Your escrow account was set up when you closed on your mortgage. Your mortgage servicer uses the funds you add to your escrow account each month to pay property taxes and homeowners insurance on your behalf. But if those costs go up, the account can fall short unless an adjustment is made to your payments. In that case, you’ll be expected to cover the difference, either through a higher monthly payment or a one-time payment.
Property taxes
When you own a home, you pay a yearly property tax amount to the county you live in. This amount is based on the value of your home and surrounding property, said Leslie Tayne, the founder of Tayne Law Group in Melville, New York. This tax amount can fluctuate based on the changing value of your home and local tax rates.
To find out if your property taxes went up, and how much, you can compare the breakdown of your taxes in prior month's mortgage statements to the breakdown of your new mortgage statement.
Home insurance
Most mortgage servicers require you to take out a homeowners insurance policy until the loan is paid off. This helps secure the bank’s asset (your home) in the event of a disaster. The monthly payment is included in your escrow account, and that amount can fluctuate, making your mortgage payment go up.
Insurance providers often review and adjust rates based on factors like inflation, claim history, home value and other economic data.
If your monthly mortgage went up to cover higher home insurance costs, there are a few things you can do to try to get a lower price. Review your current coverage to see if it's too high and could be reduced, consider raising your deductible if you can pay a higher amount out-of-pocket for repairs, or shop around for a new quote. You may be able to save even more on your home insurance by bundling it with auto insurance under one policy from one carrier.
Adjustable-rate mortgages (ARMs)
An adjustable-rate mortgage is a type of loan that typically starts with a lower interest rate than a fixed-rate mortgage. But after an initial fixed period, the rate adjusts periodically based on market conditions, which are often influenced by inflation and interest rate benchmarks.
This particular type of loan often attracts people looking for lower mortgage payments, but it can be responsible for large fluctuations in your monthly amount once that initial period ends.
If you have an ARM, do a quick check using a mortgage calculator to confirm your new payment amount matches. Use your new rate and the remaining term to calculate the expected monthly payment. If this is off from your new bill, you may also have an escrow shortage, so it's important to check your tax rate and homeowners insurance, too. And in case the numbers still don't match, ask your mortgage servicer for a line-item breakdown.
The interest rate changes for an ARM depend on the terms of the loan and the rate, said Tayne. “Initially, interest rate fluctuations won’t impact the ARM rate during the fixed period, but thereafter, it will. For example, your adjustable-rate loan might be called a ‘5 and 1.’ That means the rate is fixed for five years and then will fluctuate thereafter,” Tayne said.

The impact of escrow accounts on mortgage payments
Your mortgage servicer will do an analysis of your escrow account each year to make sure you have enough funds to cover your insurance and taxes. If those two items cost more than what's in your escrow account, you'll have what is called an escrow shortage or deficit. This means your mortgage will increase to cover last year's shortage, and likely next year's higher costs as well. This also means your mortgage could come back down some after next year, since you'll no longer be paying a previous year's shortage, too, just the new rates for your insurance and taxes.
If shifts in home insurance costs or property taxes occur, you’ll see that reflected in the amount of your mortgage payment. For example, Tayne said, “If there’s a reduction in home insurance and property taxes costs, you’ll see your payments decrease or receive a refund. But if costs increase, your monthly payment can also increase. Shortages will be your responsibility to pay.”
Tayne advised homeowners to keep a little wiggle room in their budget for these common monthly payment fluctuations. “It’s a good idea to contribute to a personal savings account every month in preparation for escrow costs shifts; you will thank yourself later,” she said.

Tayne also said, “Another good tip here is to keep a keen eye on your monthly mortgage statement, tax bills and insurance notices to look for shifts and monitor property tax and insurance shifts in the market.”
Addressing errors and new fees in mortgage payments
While your monthly mortgage payment could fluctuate a bit from month to month, there shouldn’t be dramatic swings or unexplained fees. In addition to the fees we’ve described in this article, you could see fees added for late or missed payments if you fall behind, Tayne said.
If your interest rate, taxes or insurance did not go up, and there are no added fees, it's important to reach out to your mortgage servicer to understand where the change came from and to confirm it is not in error.
Ask your lender about recasting
If you have the financial flexibility, making a one-time lump sum toward the mortgage principal could reduce your monthly payment without a refinance. This process is known as mortgage recasting.
In the case that your escrow is in deficit, you may be able to offset your increased monthly mortgage payments by paying off the full shortage as a one-time payment.

FAQ
Why did my mortgage payment just increase?
Your mortgage payment likely increased because either your property taxes or your homeowners insurance increased. These are the two most impactful (and most common) elements of your escrow account that can cause fluctuations in your monthly payment.
Can my mortgage go up without notice?
Changes like property tax increases and homeowners insurance rate increases might affect your mortgage payment without much notice. But if your monthly mortgage payment fluctuates as a result of an ARM, your mortgage servicer is required to provide you with notice before the rate changes.
Why did my mortgage payment go up because of escrow?
If your escrow account doesn’t have enough money to cover expenses like property taxes or insurance premiums, your mortgage servicer may raise your monthly payment to make up the difference. This often happens when those costs go up and your escrow contributions are short of the new amounts.
