An escrow analysis is the yearly review your mortgage servicer runs on your escrow account to confirm it’s collecting enough each month to cover your property taxes, homeowner’s insurance, and a small reserve. The servicer adds up what it expects to pay on your behalf over the next 12 months, compares that figure to what’s actually in the account, and resets your monthly payment up or down to match. You’ll get a statement showing the new amount, and it usually takes effect the following month.
What Your Escrow Account Is Paying For
Escrow is a holding account your servicer controls to pay recurring property charges tied to your mortgage. Property taxes and homeowner’s insurance premiums are in nearly every account. Depending on the loan, flood insurance or private mortgage insurance may also run through it.1Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
Billing frequency doesn’t change the math. If your county bills taxes twice a year, the servicer still collects one-twelfth of the annual total every month so the full amount is sitting there when the bill arrives. The same goes for an insurance premium that renews once a year. Municipal special assessments, like a street-paving levy or sewer improvement charge, can also flow through escrow when you and the servicer agree to include them, and they’ll push your payment up for as long as they’re active.
How Often the Analysis Happens
Federal rules require your servicer to run an escrow analysis at least once during each 12-month escrow computation year, and to send you the annual escrow account statement within 30 calendar days of the end of that year.2eCFR. 12 CFR 1024.17 – Escrow Accounts That statement lists every deposit and payment from the prior year, projects what’s needed for the next one, and tells you whether your monthly payment is changing.
The reason for the recalculation is simple. Taxes and premiums move. A reassessment, a renewal quote, or an added flood policy can throw off an account that was perfectly adequate the year before. The annual review catches the gap before a bill goes unpaid.
How the Number Is Calculated
The servicer works in a set order: project the disbursements, add the cushion, map the balance month by month, and compare the result to what’s actually in the account.
Projecting Next Year’s Disbursements
The starting point is your most recent tax and insurance bills. If your annual property tax was $6,000 and homeowner’s insurance ran $1,200, the projected annual disbursement is $7,200. When a taxing authority has already announced a rate change, the servicer uses the new figure rather than last year’s.
Adding the Cushion
On top of projected disbursements, the servicer may keep a cushion, sometimes called a reserve, to absorb unexpected increases that hit before the next analysis. Federal regulation caps this cushion at one-sixth of the estimated total annual escrow payments.2eCFR. 12 CFR 1024.17 – Escrow Accounts On $7,200 in projected disbursements, that works out to a maximum of $1,200, or about two months of escrow contributions. Some servicers collect less; none can legally collect more.
Comparing the Projection to Your Actual Balance
The servicer then maps out when payments come in and when bills go out, month by month, aiming to keep the balance from dipping below the cushion amount (or zero, if no cushion is collected) at any point in the year. The lowest projected balance usually falls right after the biggest disbursement, like a semiannual tax payment. Finally, the servicer compares the actual balance to what the projection says should be there. That comparison produces one of three results, and your new monthly escrow amount is one-twelfth of the projected annual disbursements plus any adjustment the result requires.2eCFR. 12 CFR 1024.17 – Escrow Accounts
What the Result Means for Your Payment
The outcome decides whether your monthly payment stays flat, climbs, or drops.
Surplus
A surplus means the account collected more than it needed, often because a tax bill came in lower than projected or an insurance premium dropped at renewal. If the surplus is $50 or more, the servicer must refund it within 30 days of completing the analysis. Smaller surpluses are typically credited toward next year’s payments instead of refunded.1Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
Shortage
A shortage means the balance is positive but below the projected target including the cushion. Taxes went up, the premium increased, or both, and the monthly contributions didn’t keep pace. You generally have two ways to clear it:
- Pay the shortage amount in a lump sum, so the new monthly escrow reflects only the updated base figure going forward.
- Let the servicer spread the shortage over your next 12 payments. A $600 shortage adds $50 per month on top of the new base escrow amount.
The 12-month spread is the default if you don’t respond to the statement. Either way, the base monthly escrow also adjusts to the new disbursement projection, so the shortage repayment is only part of the total change you’ll see.
Deficiency
A deficiency is the worst outcome. The balance actually went negative at some point, which forced the servicer to advance its own money to cover a tax or insurance bill. The servicer has to recover the full amount and reset the account to its proper target. Repayment is typically spread over 12 months, but combined with the recalculated base payment, the monthly increase can be steep. If the servicer advanced $1,200 to cover a tax payment the account couldn’t handle, you’d see roughly $100 per month added just to repay the advance, before any base adjustment.
Force-Placed Insurance Can Trigger a Deficiency
One common cause of a deficiency has nothing to do with tax reassessments. If your homeowner’s policy lapses or your servicer doesn’t receive proof of active coverage, the servicer can buy a replacement policy on your behalf. This is called force-placed insurance, and it’s almost always far more expensive than a standard policy because it protects the lender, not you.
Before charging you for force-placed coverage, the servicer must send a written notice at least 45 days in advance, followed by a second notice; you get an additional 15 days from the second notice to prove you have continuous coverage.3Consumer Financial Protection Bureau. 12 CFR 1024.37 – Force-Placed Insurance If you’ve had coverage the whole time and the servicer simply didn’t receive your insurer’s notice, proof cancels the policy and the charges. The premium runs through escrow, which is why force-placed coverage so often shows up as a deficiency at the next analysis.
Disputing an Escrow Analysis
Servicers make mistakes. An outdated tax bill, a double-counted disbursement, or someone else’s insurance premium can all land in your account. If you think your analysis is wrong, you can challenge it in writing.
Before you file, pull your most recent tax bill and insurance declaration page and compare the figures line by line with the escrow statement. Most errors are visible there. If the servicer projected a $7,000 tax bill and your assessment notice says $6,200, you have a documented basis for the dispute.
You can send a Notice of Error or a Request for Information. A Qualified Written Request under RESPA does the same thing, but it isn’t the only valid format. Any written communication that identifies the error and explains why you believe the analysis is wrong triggers the servicer’s obligations under federal law. After receiving your dispute, the servicer must acknowledge it within five business days and respond within 30 business days, either correcting the error or explaining with documentation why the original figure stands.4Consumer Financial Protection Bureau. What Is a Qualified Written Request (QWR)?
Keeping Your Escrow Payment Predictable
Big escrow increases catch people off guard, but the causes are usually visible months ahead. Your county publishes assessment notices before they take effect, and your insurer sends renewal quotes weeks before the premium changes. Watching those two numbers gives you a reliable preview of what the next analysis will show.
Shopping your homeowner’s insurance annually is the easiest lever you have. Property taxes are largely outside your control, though you can appeal an assessment that looks inflated. A lower premium directly reduces the disbursement projection, which lowers your monthly payment. Some states also require servicers to pay interest on escrow balances, so it’s worth checking whether yours does.
When a large increase does land, choosing the lump sum over the 12-month spread keeps a surcharge off every payment for a year. The spread exists for borrowers who can’t absorb a sudden outlay, and there’s no penalty or interest on it. Pick whichever matches your cash flow.
