What Is an Escrow Account and How Does It Work?
An escrow account, sometimes called an impound account, is set up by your mortgage lender or servicer to collect money through your monthly mortgage payment and use it to pay property-related expenses on your behalf, such as property taxes and homeowners insurance.

Rather than paying a large property tax or insurance bill once or twice a year in one lump sum, an escrow account spreads that cost out into smaller monthly amounts collected alongside your principal and interest payment. Many lenders require this arrangement, and even when it isn't required, some borrowers choose it voluntarily for easier budgeting. This guide explains exactly how escrow accounts work, what protections apply under federal law, and why your monthly payment can change even with a fixed-rate mortgage.

Definition
An escrow account is an account established or controlled by your mortgage servicer to collect and pay property-related expenses, such as taxes and insurance premiums, on the borrower's behalf, funded through a portion of the borrower's monthly mortgage payment.
What an Escrow Account Covers
Escrow accounts most commonly cover:
- Property taxes billed by your city, county, or school district.
- Homeowners insurance premiums.
- Flood insurance premiums, if your property is in a designated flood zone.
- Private mortgage insurance (PMI) or FHA mortgage insurance premiums, in many cases.
- Other required charges, such as certain HOA-related fees in specific arrangements, though this varies by lender and loan type.
Escrow accounts generally do not cover discretionary homeowner expenses like maintenance, repairs, or utility bills — only the recurring, mandatory property-related costs tied to keeping the loan and property in good standing.
How Your Monthly Escrow Payment Is Calculated
Each year, your servicer performs an escrow account analysis to estimate the total amount that will need to be paid out of the account over the next 12 months for taxes, insurance, and any other covered items. That estimated annual total is divided by 12 to determine your monthly escrow payment, which is added on top of your principal and interest payment.
| Component | How It's Determined |
|---|---|
| Property Taxes | Estimated based on your local tax authority's most recent assessment |
| Homeowners Insurance | Based on your current policy premium |
| PMI or MIP | Based on your loan's mortgage insurance requirement, if applicable |
| Cushion | An additional buffer amount, limited by federal regulation |
If your servicer estimates too low one year, you may end up with a shortage; if it estimates too high, you may end up with a surplus, both of which are addressed during the next annual analysis.
The Escrow Cushion Limit
Federal regulation allows servicers to collect a cushion, an extra buffer amount, in addition to the actual estimated disbursements, to help ensure the account doesn't run into a negative balance if a bill comes in higher than expected. Under Regulation X, this cushion is generally limited to no more than one-sixth of the total estimated annual disbursements from the account, which works out to roughly two months' worth of escrow payments. This limit applies both when the account is first established and during subsequent annual analyses, so a servicer cannot build an unlimited buffer into your monthly payment.
Why Your Mortgage Payment Can Change
Even with a fixed-rate mortgage, your total monthly payment can still increase or decrease over time because property taxes and insurance premiums are not fixed. If your local tax assessment rises or your insurance premium increases at renewal, your servicer will adjust your monthly escrow contribution accordingly at the next annual analysis, even though your principal-and-interest amount stays exactly the same. This is one of the most common sources of confusion for homeowners who assume a "fixed-rate mortgage" means a permanently fixed total payment.
Escrow Shortages vs. Escrow Surpluses
- Escrow shortage — occurs when the account has collected less than what was actually needed to cover disbursements. Depending on the size of the shortage, your servicer may spread the make-up amount over the next 12 months, or in some cases accept a voluntary lump-sum payment from the borrower to resolve it faster, though servicers generally cannot require a lump sum for smaller shortages.
- Escrow surplus — occurs when the account has more than it needs. Depending on the surplus amount, some or all of it may be refunded to the borrower or applied toward the next year's payments, subject to specific regulatory thresholds.
Your servicer is required to send you an annual escrow account statement showing the account's activity over the past year and a projection for the year ahead, which is the best resource for understanding exactly why your payment changed.
Is Escrow Required
Escrow is not universally required on every mortgage, but many lenders require it, particularly for loans with smaller down payments or loans considered "higher-priced" under the Truth in Lending Act, which may require escrow for a minimum period after origination. FHA loans generally require escrow for the life of the loan. Even when escrow isn't required, some borrowers choose to set one up voluntarily, since it removes the need to budget separately for large annual or semiannual tax and insurance bills.
Step-by-Step: Reviewing Your Escrow Statement
- Locate your most recent annual escrow account statement from your servicer.
- Compare the estimated disbursements from last year to what was actually paid out.
- Check whether your account shows a shortage, surplus, or is roughly on target.
- Review your new monthly escrow payment for the coming year and confirm it reflects your current tax and insurance costs.
- Contact your servicer directly if a change seems unusually large or doesn't match a known increase in your tax bill or insurance premium.
- Keep a copy of your escrow statements for your records, especially around refinancing or paying off your loan.
A Real-World Example
A homeowner with a fixed-rate mortgage sees their total monthly payment increase by $85, even though their interest rate and loan term haven't changed. After reviewing their annual escrow statement, they discover their county reassessed their property, raising their annual tax bill by roughly $900. Spread across 12 months, that increase alone accounts for the $75 portion of the payment change, with the remainder tied to a smaller increase in their homeowners insurance premium at renewal. Understanding this breakdown helps the homeowner see that their loan terms didn't change — only the underlying costs the escrow account is funding.
Common Mistakes
- Assuming a fixed-rate mortgage means a permanently fixed total monthly payment.
- Not reviewing the annual escrow statement when a payment change notice arrives.
- Paying property tax or insurance bills directly in addition to escrow contributions, resulting in duplicate payments.
- Assuming an escrow surplus refund means something is wrong with the loan.
- Not contacting the servicer promptly when a shortage or surplus doesn't seem to make sense.
Expert Tips
- Read your annual escrow statement carefully each year rather than assuming the payment change is an error.
- Keep records of your property tax bills and insurance premiums to compare against your escrow statement.
- If you believe your servicer's estimate is inaccurate, contact them directly and request a review before assuming the number is final.
- If your loan doesn't include escrow, set aside your own monthly savings for taxes and insurance to avoid a large lump-sum surprise.

Frequently Asked Questions
Can I opt out of an escrow account?
It depends on your lender and loan type. Some borrowers can request to waive escrow, particularly with a larger down payment on a conventional loan, while others — such as many FHA borrowers — are required to maintain escrow for the life of the loan.
Why did my mortgage payment increase if my interest rate is fixed?
Your principal-and-interest amount stays the same with a fixed-rate mortgage, but your total payment can still change if the escrow portion increases due to higher property taxes or insurance premiums.
What happens to my escrow balance if I pay off my mortgage?
Your servicer is generally required to return any remaining escrow balance to you within a set number of days after your loan is paid in full, subject to applicable regulations.
How much extra can my servicer collect as an escrow cushion?
Federal regulation generally limits the cushion to no more than one-sixth of the estimated total annual disbursements, roughly equivalent to two months' worth of escrow payments.

Conclusion
An escrow account is designed to make property tax and insurance payments more predictable by spreading them across your monthly mortgage payment, but it's also the most common reason a "fixed" mortgage payment changes over time. Reviewing your annual escrow statement each year is the best way to understand exactly why your payment moved, and to catch potential errors early. This article is educational only and not financial or legal advice; escrow requirements and limits can vary by lender, loan type, and state, so confirm your specific account details with your mortgage servicer.
