Mortgage Escrow Accounts Explained: Why Your Monthly Mortgage Payment Can Change
What is a mortgage escrow account?
A mortgage escrow account — sometimes called an impound account — is an account a mortgage lender or servicer uses to collect and pay certain property expenses on the borrower's behalf.
Instead of paying a large tax or insurance bill once or twice a year, the borrower contributes an estimated portion with each regular mortgage payment. The servicer holds those funds and pays the included bills when they become due.
What escrow is
A payment-management account that collects estimated property-expense portions monthly and pays included bills when due.
What escrow is not
Not a loan, a credit line, or a home-equity account. Escrow deposits do not reduce principal or build equity.
Not the closing escrow
The word "escrow" is also used for the real estate closing (earnest money, documents). That closing function is separate from the ongoing mortgage escrow account.
Mortgage escrow helps manage recurring property expenses. It is not another loan or a home-equity account.
How mortgage escrow works
Every month, part of the payment goes to principal and interest on the loan and part goes into the escrow account. When included bills are due, the servicer pays them. Once a year, the servicer reviews the account and adjusts the contribution if the projected bills changed.

What may be included in escrow
The specific loan documents and account statement identify included items. Use those — not a general list — to confirm what your account actually covers.
Property taxes
County, city, school district, or other real property taxes paid to the taxing authority when due. The tax bill is set by the authority — the servicer funds it.
Homeowners insurance
The required property insurance premium. The insurer determines the premium; the servicer generally collects and disburses the amount.
Flood or other required property insurance
If flood insurance or another coverage is required and designated for escrow, its premium may be included in the contribution.
Mortgage insurance
Some mortgage-insurance premiums may be collected within the total payment or escrow structure. The exact administration depends on the loan and insurance type.
Other permitted property charges
The mortgage documents may identify additional charges. Always verify with the actual account statement.
What is usually outside escrow
An escrow account is not a complete homeownership budget. Expenses commonly paid outside the mortgage escrow account include:
Why a fixed-rate mortgage payment can change
With a standard fixed-rate mortgage, the interest rate generally remains unchanged for the loan term. The total payment can still change because it contains other components.
Select each reason below to understand what drives each type of change.
A fixed-rate mortgage generally fixes the interest rate — not property taxes, insurance premiums, or the total amount sent to the servicer.
How annual escrow analysis works
An escrow analysis is the servicer's review of expected deposits, expected disbursements, and the account's projected running balance. For covered accounts, this generally happens at the end of each computation year, with a statement explaining past activity and the upcoming projection.
The look-back
- Monthly deposits credited
- Tax and insurance disbursements made
- Ending account balance
- Difference between expected and actual bills
- How prior shortage or surplus was handled
The look-forward
- Which bills will be paid
- When they are expected to be due
- How much they are expected to cost
- Permitted target balance and cushion
- Monthly amount needed for the coming period

Escrow vs. principal and interest
The components of a mortgage payment serve different purposes and follow different drivers.
| Principal & interest | Escrow |
|---|---|
| Repays the mortgage and compensates the lender for lending | Funds included property expenses |
| Determined by loan balance, rate, term, and structure | Determined by projected taxes, insurance, timing, and account balance |
| Generally stable on a standard fixed-rate loan | Can increase or decrease after each analysis |
| Principal reduces the loan balance | Escrow deposits do not reduce principal |
| Interest rate is established by the note | Tax authorities and insurers determine the underlying bills |
How to review an escrow statement
Treat the annual escrow statement as a reconciliation of the past year and a forecast for the next. Work through each step in order.
Compare the old and new total payment
Identify the change in principal and interest, escrow contribution, mortgage insurance, shortage or deficiency repayment, and other listed amounts. This shows whether escrow is actually responsible for the payment change.
Review the prior year's activity
Confirm each monthly escrow deposit was credited, tax payments match the taxing authority's records, insurance payments match insurer invoices, and disbursements went to the correct property and policy.
Review the new projections
Compare projected tax and insurance amounts with current bills or renewal notices. Ask what source the servicer used if they differ.
Separate future cost from past shortage
The statement may show one amount needed for upcoming bills and another to repay a shortage. Ask what the payment would be after any shortage-repayment period ends, assuming the underlying bills do not change again.
Check the effective date
Confirm when the new payment begins. Update automatic payments or bill-pay instructions if they do not adjust automatically.
Keep supporting documents
Retain the annual analysis, mortgage statements, tax bills, insurance declarations, and proof of any direct payments. These records help identify the source of a discrepancy.
What to do when the payment changes
Confirm the rate and loan terms
Check whether the mortgage is fixed-rate, adjustable-rate, temporarily bought down, modified, or subject to another changing feature. Do not assume every increase is escrow-related.
Contact the servicer
Ask for a plain-language explanation of the old and new escrow contribution, each projected bill, the shortage or surplus, the permitted cushion, repayment options, and the effective date of the new payment.
Contact the tax authority or insurer when appropriate
The servicer generally does not set the property-tax assessment or insurance premium. If the underlying bill appears wrong, contact the entity that issued it — the taxing authority or insurer — while keeping the servicer informed.
Correct insurance information promptly
If a policy changed, was replaced, or was canceled, provide current coverage and billing information to the servicer. Duplicate policies, missing renewals, or force-placed insurance can create serious cost and coverage problems.
Use the formal error process when needed
If an included bill was not paid, a deposit was misapplied, or the analysis appears incorrect, contact the servicer promptly. Federal mortgage-servicing rules may provide a written notice-of-error or information-request procedure. Follow the designated address — a phone call alone may not create a formal record.
Escrow at purchase, refinance, and servicing transfer
At purchase
The buyer may deposit initial escrow funds at closing so the account has enough money when the first included bills become due. This amount appears in the closing disclosures and is separate from the recurring monthly contribution.
At refinance
The old escrow account and the new loan's escrow funding are separate transactions. A borrower may need to fund the new account at closing before receiving a refund from the former servicer, temporarily increasing the cash required.
After a servicing transfer
When servicing moves to a new company, escrow funds and records should transfer. Review the final statement from the old servicer and the opening statement from the new one.
When escrow ends
Not every mortgage requires escrow for its entire term, but cancellation or waiver is not always available. Loan type, legal requirements, lender or investor rules, LTV, payment history, fees, and written terms may apply.
Escrow decision framework
Four questions to understand a mortgage escrow account.
What is included?
List every tax, insurance premium, and other charge the servicer is expected to pay. List major ownership costs outside escrow separately so the household budget accounts for them.
What changed?
Compare actual prior bills, new projections, the account balance, and the old and new contribution. Identify whether the increase comes from future costs, a prior shortage, or both.
Who controls the amount?
The tax authority sets tax bills. The insurer sets premiums. The servicer administers the escrow calculation and payment. Send a dispute or question to the party responsible for the relevant input.
What should the household budget?
Use the new required payment — not last year's amount. Maintain a buffer for future tax and insurance changes, plus separate reserves for maintenance, deductibles, and association assessments.

Frequently asked questions
What is a mortgage escrow account?
It is an account a mortgage lender or servicer uses to collect money through regular payments and pay certain property-related expenses — commonly property taxes and homeowners insurance — on the borrower's behalf.
What expenses are paid through escrow?
Common items include property taxes and required property-insurance premiums. The actual account may also include flood insurance, mortgage insurance, or other permitted charges. Review the mortgage documents and annual statement.
Why did my fixed-rate mortgage payment increase?
The principal-and-interest amount may be stable while the escrow contribution rises because taxes, insurance premiums, or a prior shortage changed. A fixed-rate mortgage fixes the interest rate — not taxes, insurance, or the total payment.
What is an escrow shortage?
A shortage means the account balance is below its calculated target. Higher or underestimated bills and timing differences are common causes. A shortage can occur even when every required payment was made on time.
What is an escrow deficiency?
A deficiency generally means the escrow account has a negative balance, often because the servicer advanced funds to pay an included bill when the account lacked enough money.
What is an escrow surplus?
A surplus means the account balance exceeds its calculated target. Lower bills, overestimates, or timing differences can cause a surplus. Rules and account status determine whether it is refunded or otherwise handled.
Can my escrow payment decrease?
Yes. Lower projected taxes or insurance premiums, or a shortage repayment period ending, can reduce the required escrow contribution — if the underlying bills stay the same.
Does escrow affect my mortgage interest rate?
No. The escrow contribution does not change a fixed interest rate. Escrow changes the total amount sent to the servicer each month because it funds separate property expenses.
Are HOA dues included in mortgage escrow?
HOA and condominium dues are often paid directly to the association rather than through escrow. Confirm the specific loan and association arrangements and budget for them separately.
Can I remove my escrow account?
Possibly, but not for every mortgage. Loan terms, applicable law, investor rules, equity, payment history, and fees may affect eligibility. Ask the servicer for written requirements.
