Escrow, Explained: Taxes and Insurance Inside Your Monthly Payment
Published 2026-11-08 · eLoanTree Blog
When most people imagine a mortgage payment, they picture principal and interest: the money that pays down the loan and the cost of borrowing it. For many homeowners, the actual monthly payment is larger than that, because it also includes escrow.
Escrow is a separate account your loan servicer holds to pay your property taxes and homeowners insurance on your behalf. You do not see those bills directly. You pay a twelfth of the estimated annual cost each month, the servicer holds the money, and the servicer pays the bills when they come due.
Understanding escrow matters because it explains why your monthly payment can rise even when your interest rate never changes, and why a letter about an "escrow shortage" is not a bill for something you did wrong.
Key Takeaways
- Escrow is a separate account your loan servicer holds to pay your property taxes and homeowners insurance: you pay a twelfth of the estimated annual cost each month, and the servicer pays the bills when they come due.
- In the article’s illustration, $3,600 a year in property taxes plus $1,800 a year in homeowners insurance is $5,400 a year, or about $450 a month in escrow.
- Federal law (RESPA, through Regulation X) allows the servicer to keep a cushion of up to one-sixth of total estimated annual escrow disbursements — roughly two months of escrow payments.
- At least once a year the servicer must perform an escrow analysis and send a statement within 30 calendar days of the end of the escrow computation year, identifying a surplus, a shortage, or a deficiency.
- A surplus of $50 or more must be refunded within 30 days if you are current on the loan; a shortage of one month’s escrow payment or more cannot be demanded as a lump sum and must be repayable over at least 12 months.
- When your monthly payment rises but your interest rate has not changed, escrow is the first place to look — and the annual statement is where the explanation lives.
1. What escrow is
An escrow account — sometimes called an impound account — is a holding account managed by your loan servicer, the company you send your mortgage payment to. Each month, part of your payment goes into escrow. When your property tax bill or your homeowners insurance premium comes due, the servicer pays it out of that account.
A simple illustration: suppose your property taxes are $3,600 a year and your homeowners insurance is $1,800 a year. That is $5,400 a year, or $450 a month. Your monthly escrow deposit would be about $450, on top of your principal-and-interest payment.
The servicer collects $450 every month, and when the tax bill arrives, it pays the county from the money it has collected. When the insurance premium is due, it pays the insurer the same way.

2. Who has escrow, and can you skip it?
Whether escrow is required depends on your loan. Many FHA loans require escrow. Conventional loans often require it when the down payment is small — generally when the loan is more than 80% of the home's value — and may allow you to waive it once you have more equity, usually for a fee or a slightly higher rate, depending on the lender and the loan program.
Some borrowers with large down payments and strong credit can choose to pay taxes and insurance themselves, but then they must be disciplined enough to save for two large annual bills on their own. Missing a tax payment can lead to a tax lien; missing an insurance payment can leave the home uninsured. Escrow exists to prevent exactly those failures.
3. The cushion: why the account holds a little extra
Your servicer does not collect exactly one-twelfth of the annual bills and stop there. Federal law allows the servicer to keep a cushion — a reserve — of up to one-sixth of the total estimated annual escrow disbursements, which works out to roughly two months of escrow payments.
That cushion covers small increases in taxes or insurance that happen between annual reviews, so the account does not go negative the moment a bill comes in slightly higher than expected.
The cushion is a maximum, not a target the servicer must always hold, and it is set by the Real Estate Settlement Procedures Act (RESPA), implemented through Regulation X. Your state may set a lower limit. The cushion is also why your escrow balance at any given moment is higher than the amount needed for the next bill alone: part of it is the reserve.
4. The annual escrow analysis
At least once a year, your servicer must perform an escrow analysis and send you a statement within 30 calendar days of the end of the escrow computation year. That statement compares what was collected and paid over the past year with what is projected for the coming year, and it identifies whether the account has a surplus, a shortage, or a deficiency.
Those three words have specific meanings. A surplus means the account holds more than the target balance — more than the coming year's projected payments plus the allowable cushion. A shortage means the account balance is positive but below the target needed for next year's payments plus the cushion. A deficiency means the account has gone negative — the servicer already paid out more than the account held.
5. What happens with a surplus
If the analysis shows a surplus of $50 or more, the servicer must refund it to you within 30 days of the analysis, as long as you are current on your loan. If the surplus is under $50, the servicer may either refund it or credit it toward next year's escrow payments. The servicer cannot keep a surplus above the allowed cushion, and it cannot apply it to your principal balance or to other fees without your agreement.
6. What happens with a shortage
A shortage is the letter that worries people, but the rules around it are protective. If the shortage is less than one month's escrow payment, the servicer can leave it alone, ask you to repay it within 30 days, or spread the repayment over at least 12 months.
If the shortage is one month's escrow payment or more, the servicer cannot demand a lump-sum payment. It must allow you to repay it over at least 12 months — or it can leave the shortage alone.
What a shortage usually means in practice is a higher monthly payment next year. Your new monthly escrow deposit will be recalculated to cover the coming year's higher taxes or insurance, plus a twelfth of the shortage spread over the year.
So if your property taxes rose by $600 and your insurance by $300, your escrow portion rises by about $75 a month, plus any shortage repayment. That is why a payment can jump by $100 or more with no change to your interest rate: the loan did not get more expensive, the taxes and insurance did.
7. How to read your escrow statement
8. The bottom line
Escrow is your taxes and insurance, paid a month at a time, held by your servicer, and paid out when the bills come due. Federal rules cap the cushion at about two months of payments, require an annual analysis, require refunds of surpluses of $50 or more within 30 days, and prevent the servicer from demanding a lump sum for a shortage of one month's payment or more.
When your monthly payment rises and your rate has not changed, escrow is the first place to look — and the annual statement is where the explanation lives.
