You are not alone this year, and the scale of it is worth knowing before you read anything else. Cotality projected that roughly 65% of escrow accounts would face a shortage in 2026, at an average of about $2,157, according to CNBC's May 2026 reporting. Around four in five borrowers have an escrow account at all. So the letter in your hand is closer to the norm than the exception.
The second thing worth knowing is that a fixed rate was never a fixed payment. A 2026 LERETA survey found 45% of homeowners believe a fixed rate means their payment cannot change, up from 36% in 2024. It fixes the principal-and-interest half. The other half, your escrow deposit, is an estimate of your property taxes and homeowners insurance, and estimates get redone.
An escrow analysis is a once-a-year review in which your mortgage servicer reconciles what your escrow account (called an impound account in some western states) actually took in and paid out, re-estimates the next twelve months of property taxes and insurance, and computes the monthly deposit needed to cover them. The letter it sends is the annual escrow account statement, sometimes printed as the annual escrow account disclosure statement. It is not a courtesy. Under RESPA (Regulation X) the servicer must send it within 30 days of the end of the computation year (12 CFR 1024.17(i)), and the rule spells out what it has to contain: your current payment and the escrow portion of it, next year's payment and escrow portion, everything paid in and everything paid out itemized by category, the ending balance, how any surplus, shortage, or deficiency will be handled, and an explanation if the projections and the actual activity differed.
Two related documents are easy to confuse with it. The initial escrow account statement is a different thing entirely, handed to you at settlement or within 45 days after (12 CFR 1024.17(g)), and it sets the account up rather than reconciling it. If you want to see where your account started, that one is in your closing packet, and our Closing Disclosure guide covers the initial escrow payment and the aggregate adjustment that go with it. The other is the short-year statement, due within 60 days when servicing transfers or the loan pays off (12 CFR 1024.17(i)(4)). If your loan was sold mid-year, that is why you got a statement covering an odd stretch of months.
One structural rule shapes everything below. RESPA requires aggregate accounting (12 CFR 1024.17(c)(4)): the servicer treats taxes and insurance as one pooled account with one running balance, not as separate buckets. That is why the whole analysis comes down to a single line on a single chart. As of August 2026 these rules are unchanged.
The four sections of the statement
Layouts differ by servicer, but nearly every annual escrow analysis has the same four parts in the same order.
1. The summary. A short paragraph naming the finding: surplus, shortage, or deficiency, with the dollar amount and what the servicer is doing about it. This is the conclusion, printed first. Read it, then go check the work.
2. The payment comparison. A small side-by-side of your current payment and your new one, usually split into principal and interest, base escrow, and shortage or deficiency repayment. Servicers call the new escrow line the total new escrow amount, and the date it starts the new payment effective date. That date is the one to act on, because autopay set to the old amount becomes a partial payment the day it passes, and a partial payment can sit in a suspense account instead of counting as paid.
3. The account history. Twelve rows comparing projected activity against actual activity, month by month, for the year just ended. This is the section people skip and the one that actually explains the increase. Find the month where the actual disbursement exceeded the projection, and you have found the bill that caused it. If your servicer paid $2,700 in November against a $2,400 projection, the county reassessed you and the letter is downstream of that.
4. The projections. Next year's twelve rows: the deposit going in each month, the bills going out, and the running balance after each. At the bottom sit the three numbers everything turns on: the required balance (the cushion), the lowest projected balance, and the gap between them. Some servicers call the repayment period the spread.
Here is what those parts look like with numbers on them. Hover or tap any field for what it does.
- HeaderComputation year
- The twelve months this analysis projects. The statement is due within 30 days of the prior computation year ending, so the letter always lands right before the new year of payments starts.
- ProjectionBeginning escrow balance
- What is actually in the account on day one of the new year. Every number below is built on this figure, so it is the first thing to check against the last statement you got.
- ProjectionProjected property taxescheck it
- What the servicer expects your county to bill, usually the most recent actual bill carried forward. Two installments here, one in May and one in November.
- ProjectionProjected hazard insurancecheck it
- The renewal premium your carrier quoted, disbursed once in September. If this jumped, your insurance renewal is where the payment increase started.
- PaymentNew base monthly escrow
- One twelfth of the projected disbursements ($7,620 ÷ 12). This is the going-forward deposit, and it is the part that does not go away when you pay a shortage off.
- CushionRequired balance (cushion)
- The reserve the account is allowed to hold, capped at one-sixth of annual disbursements, so two months of escrow here. This is the target the projection is measured against, not zero.
- CushionLowest projected balance
- The bottom of the running balance across the twelve projected months. It lands in November here, right after the second tax installment.
- ResultEscrow shortagecheck it
- Required balance minus lowest projected balance ($1,270 − $310). Not a negative balance, and not a bill you have to pay at once.
- ResultShortage repayment (12 months)
- The shortage spread over the minimum twelve months ($960 ÷ 12). This installment comes off after a year, which is why next year's payment often drops back partway.
- PaymentTotal new monthly escrow
- Base deposit plus shortage installment ($635 + $80). Compare it to last year's escrow line to see the real size of the change.
- PaymentNew payment effective datecheck it
- The first payment at the new amount. Update your autopay before this date, because a payment short by the escrow increase is a partial payment.
- PaymentNew total monthly payment
- Principal and interest of $1,450.00, unchanged on a fixed-rate loan, plus the new $715.00 escrow. Last year it was $2,000.00.
The shortage math, worked
This is the part no lender page shows you, and it is not hard. Here is the whole example, start to finish.
Last year the account covered property taxes of $4,800 (two $2,400 installments, May and November) and homeowners insurance of $1,800 (one September premium). That is $6,600 a year, so the base escrow deposit was $550.00 a month. With principal and interest of $1,450.00, the total payment was $2,000.00.
Then two things happened. The county reassessed the property and the tax bill rose to $5,400, split into two $2,700 installments. The insurer renewed at $2,220, up $420. Projected disbursements for the new year are now $5,400 + $2,220 = $7,620.
Step one: the new base deposit. One twelfth of the projected disbursements. $7,620 ÷ 12 = $635.00 a month. RESPA caps the monthly charge at exactly this, one twelfth of anticipated annual disbursements plus whatever is needed for the cushion (12 CFR 1024.17(c)(1)). The base deposit is already $85.00 more than last year, before any shortage enters the picture.
Step two: the required balance. The account is allowed a cushion, capped at one-sixth of annual disbursements, which is two months (12 CFR 1024.17(c)(1)). $7,620 ÷ 6 = $1,270.00. Your loan documents or your state can require less, and some require none, but nothing permits more. The target is not zero. It is $1,270.00 at the account's lowest point.
Step three: the projection. Start with the balance actually in the account, $945.00, add $635.00 a month, and subtract each bill in the month it falls due.
| Month | Deposit in | Paid out | Running balance |
|---|---|---|---|
| Opening balance | – | – | $945.00 |
| January | $635.00 | – | $1,580.00 |
| February | $635.00 | – | $2,215.00 |
| March | $635.00 | – | $2,850.00 |
| April | $635.00 | – | $3,485.00 |
| May | $635.00 | $2,700.00 taxes | $1,420.00 |
| June | $635.00 | – | $2,055.00 |
| July | $635.00 | – | $2,690.00 |
| August | $635.00 | – | $3,325.00 |
| September | $635.00 | $2,220.00 insurance | $1,740.00 |
| October | $635.00 | – | $2,375.00 |
| Novemberlowest | $635.00 | $2,700.00 taxes | $310.00 |
| December | $635.00 | – | $945.00 |
Step four: find the bottom. The lowest projected balance is $310.00, in November, right after the second tax installment. Not May, and not December. It is worth seeing as a shape, because the shape is what makes the cushion rule make sense:
Step five: the shortage. Required balance minus lowest projected balance. $1,270.00 − $310.00 = $960.00. The account never goes negative anywhere in that table, which is exactly why this is a shortage and not a deficiency.
Step six: the spread. A shortage of a month or more is repaid over at least twelve months. $960.00 ÷ 12 = $80.00 a month.
Step seven: the new payment. Base deposit plus shortage installment. $635.00 + $80.00 = $715.00 of escrow a month, against $550.00 last year. Add the unchanged $1,450.00 of principal and interest and the total payment goes from $2,000.00 to $2,165.00. The rate never moved.
Hold your own statement next to those seven steps. If your servicer's numbers do not reconcile the same way, you have a specific question to ask rather than a general complaint, and the section on disputing an error below tells you how to ask it in writing.
Surplus, shortage, deficiency: what the servicer may actually do
Three findings are possible, and the size of each changes the rules. A surplus means the account holds more than it needs. A shortage means the projected balance dips below the required balance while staying positive. A deficiency means the account actually went negative, because a bill came due and the servicer paid it out of its own pocket. None of the handling is discretionary. RESPA sets a menu for each:
| What the analysis finds | What it means | What the servicer may do |
|---|---|---|
| Surplus of $50 or more | The account holds more than the required balance. | The servicer must refund it to you within 30 days of completing the analysis, as long as you are current on the loan (12 CFR 1024.17(f)(2)(i)). This is the escrow refund check. |
| Surplus under $50 | A small overage. | The servicer may refund it or credit it against the next year's escrow payments, its choice (12 CFR 1024.17(f)(2)(ii)). If you are more than 30 days past due, it may keep the surplus in the account instead (12 CFR 1024.17(f)(2)(iii)). |
| Shortage under one month's escrow payment | A small projected dip below the cushion. The account is still positive. | Three options: leave it alone, ask you to pay it within 30 days, or spread it over twelve months or longer (12 CFR 1024.17(f)(3)(i)). |
| Shortage of one month or more | The usual case, and the one behind most payment increases. | Two options only: leave it alone, or collect it in equal monthly payments over at least twelve months (12 CFR 1024.17(f)(3)(ii)). No lump-sum demand. A voluntary lump sum may be accepted. |
| Deficiency under one month's escrow payment | The account actually went negative. The servicer advanced its own money to pay a bill. | Three options: do nothing, ask for repayment within 30 days, or collect it in two or more equal monthly payments (12 CFR 1024.17(f)(4)(i)). |
| Deficiency of one month or more | A larger negative balance. | Two options: do nothing, or collect it in two or more equal monthly payments (12 CFR 1024.17(f)(4)(ii)). Both deficiency rules apply only while you are current (12 CFR 1024.17(f)(4)(iii)). |
Two lines in that table are worth memorizing. First, a surplus of $50 or more is yours, and it has to be back in your hands within 30 days if you are current. That is the escrow refund check people ask about. Second, for a shortage of one month or more, the servicer cannot require a lump sum. It can offer one. It can accept one you volunteer. It cannot demand one. If a letter reads like a demand, reread it: most of them are offering a choice in language that sounds like a bill.
Should you pay the shortage all at once?
Here is the thing almost every servicer page leaves out, and the single most common confusion homeowners post about: paying the shortage in full does not stop your payment from going up.
Look at the two numbers again. The new escrow payment is $715.00, made of a $635.00 base deposit and an $80.00 shortage installment. Writing a $960.00 check kills the installment. It does nothing to the base deposit, because the base deposit exists for a completely different reason: your taxes and insurance genuinely cost more now. So the lump-sum path lands you at $635.00 a month, not back at the old $550.00. Against the spread path's $715.00, the check buys an $80.00 monthly reduction. It does not buy last year's payment back.
Two other things follow from that. If you pay the shortage and your servicer does not re-run the analysis, your payment may not drop until the next annual cycle, so ask for a re-analysis in writing when you send the money. And if you pay it and the underlying bills rise again next year, you will have a fresh shortage anyway, because the shortage was a symptom.
As pure finance, spreading wins and it is not close. The RESPA repayment carries no interest. It is a twelve-month loan at zero percent from your servicer, and money you keep for a year is worth more than money you hand over today. Pay the lump sum anyway if you want one simpler number on the statement, or if the cash is sitting idle and you would rather not think about it again. That is a preference, and a legitimate one. Just do not pay it expecting the payment increase to go away, because it will not.
Why it went up this year
Only two bills live in a normal escrow account, so the cause is always one of them, or both.
Insurance. Insurify's March 2026 analysis put average home insurance at $2,948 in 2025, up 12% for the year, and projected $3,057 for 2026. That is a 46% rise since 2021. If your homeowners policy renewed with a higher premium, the servicer projects the new number forward and your deposit rises with it.
Property taxes. ATTOM's 2025 annual property tax report put the average single-family tax bill at $4,427, up 3% year over year, with an effective rate of 0.9%, the highest since 2020. Reassessments, expiring exemptions, and new levies all land here. Your property tax bill is the document that shows which one happened.
The new-construction trap. This one deserves its own paragraph, because it is brutal and largely undocumented. If you bought new construction, the first escrow analysis was almost certainly built on a land-only tax bill, assessed before the house existed. When the county reassesses the finished home, the tax bill can more than double, and the escrow account is instantly short by a year's worth of the difference. Worse, many counties then issue a supplemental tax bill for the gap between the old assessment and the new one, and that bill is frequently sent to you directly and is not paid out of escrow. People assume it is, ignore it, and collect penalties. If you are in your first or second year in a new-construction home, call your servicer and your county and confirm in writing who pays the supplemental bill. One first-year homeowner on Reddit described exactly this stack: an escrow account $860 short after the reassessment, and a monthly payment up $231.
Two smaller causes. Force-placed insurance, which a servicer can buy and charge to your escrow if it believes your own policy lapsed, costs far more than a policy you would buy yourself. And a servicing transfer mid-year can leave the new servicer projecting from incomplete history. Both show up on the account history section as an actual disbursement with no matching projection.
One thing that is not on this list: mortgage insurance. PMI is not part of the escrow analysis, and when it drops off is governed by the Homeowners Protection Act, not RESPA. Our mortgage statement guide covers the three markers for that, along with what the escrow line on the monthly bill is doing between analyses.
When the increase is actually an error
Most escrow increases are correct and unwelcome. Some are simply wrong. These are the errors worth checking for specifically:
- The wrong parcel. The servicer paid taxes on a parcel that is not yours. It happens, and the servicer is responsible for making the account whole.
- A missing exemption. A homestead, senior, veteran, or agricultural exemption that should have reduced the bill was not applied by the county. Fix it at the county, then ask for a re-analysis.
- Duplicate insurance. You switched carriers and the servicer paid both the old policy and the new one.
- Force-placed insurance you did not need. The servicer bought coverage even though your policy was active. Send the declarations page and have the charge reversed.
- A balance lost in a transfer. Your old servicer's ending escrow balance does not match the new servicer's opening balance.
- Arithmetic that does not reconcile. Run the seven steps above. If the required balance exceeds one-sixth of projected disbursements, or the shortage is not the gap between the required balance and the lowest projected balance, say so.
The way to raise any of these is a written notice of error under 12 CFR 1024.35 (the successor to what older guides call a qualified written request, or QWR). Put it in writing, name the account, state the specific error, and send it to the address the servicer designates for notices of error (not the payment address). The clocks are real: the servicer must acknowledge within 5 business days and either correct the error or explain why it is not an error within 30 business days, with one 15-day extension available. Keep a copy of what you sent and the date. When a correction lands, ask explicitly for a re-analysis, because fixing the underlying bill does not automatically recompute your monthly payment.
Getting out of escrow, honestly
The obvious reaction to a $165 increase is to ask whether you can just pay the taxes and insurance yourself. Sometimes you can. Here is the honest version.
An escrow waiver is generally available on conventional loans at 80% loan-to-value or lower, meaning you have at least 20% equity. It usually costs a fee at origination, typically 0.25% to 0.50% of the loan amount, charged either as points or as a slightly higher rate. On an existing loan some servicers will remove escrow on request and some will not, and the ones that do often charge for it. FHA loans can never waive escrow.
The part people underweight: a waiver is revocable. Miss a payment, or let a tax bill or insurance policy go unpaid, and your lender can reinstate escrow, and now you are funding an account from zero on top of the payment you already had. You are also taking on the job of setting aside roughly $635 a month yourself, on time, for bills that arrive in unhelpful lumps. If the reason escrow annoys you is that the money is not yours to hold, a waiver fixes that. If the reason is that the bills went up, a waiver fixes nothing. You still owe $7,620.
Does escrow earn interest?
Federal law does not require servicers to pay interest on escrow balances. Roughly 14 states do, including California, Connecticut, Iowa, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New York, Oregon, Rhode Island, Utah, Vermont, and Wisconsin. Rates and rules vary by state, and where interest is owed it should appear on your annual statement. One caveat as of August 2026: a January 2026 OCC proposal to preempt state escrow-interest requirements for national banks is being contested in court, so if you are in one of those states and the interest line vanished from your statement, that is the reason to ask about it rather than assume.
What to keep, and why next year's letter is easier
You do not need to keep every monthly mortgage statement. The two documents a year genuinely worth filing are the annual escrow account statement and your Form 1098. The escrow statement is worth keeping for one specific reason: it is the only thing that makes next year's letter readable. Put this year's projections next to next year's account history and the actual-versus-projected columns tell you in ten seconds whether the county, the insurer, or the servicer's estimate caused the change.
It works best filed with its two sources. The escrow analysis, the property tax bill, and the homeowners insurance policy are one story told in three documents, and they arrive months apart from three different senders, which is exactly how they end up in three different places. Our home filing system guide covers where they go, and the retention guide has how long to hold each one.
That is the dull job Granite exists for. Drop in the escrow analysis, the tax bill, and the insurance renewal, and Granite reads and files each one alongside your mortgage statements, without you tagging anything. Next August, when the letter arrives, you can ask what your premium renewed at last year, or what the county billed in November, and get the answer with a citation to the page it came from. To be clear about what Granite is not: we are not your lender or servicer. We cannot change your escrow, run a re-analysis, or file a notice of error for you, and none of this is legal or tax advice. We keep the paperwork in one place so that when you make that call, you have the documents in front of you.
