Short answer: Escrow is the part of your monthly mortgage payment that your lender holds in a separate account and uses to pay your property taxes and homeowners insurance when they fall due. Instead of one large tax bill once or twice a year, you pay a twelfth of the yearly total each month. On a $400,000 home with $4,800 a year in taxes, $2,400 a year in insurance and $150 a month in PMI, escrow adds exactly $750 a month — and federal law caps the extra cushion your servicer may hold at two months of escrow payments.

What Escrow Is and Why Lenders Require It
An escrow account — called an impound account in some states, especially on the West Coast — is an account your mortgage servicer sets up to pay certain property-related expenses on your behalf. The Consumer Financial Protection Bureau (CFPB) defines it plainly: the money comes from a portion of your monthly mortgage payment, and the servicer pays the bills from it when they come due. Taxes and insurance arrive as large bills once or twice a year; escrow turns them into twelve smaller monthly amounts.
Lenders require escrow because unpaid taxes and lapsed insurance threaten their collateral. Unpaid taxes can put a lien on the home that takes priority over the mortgage; lapsed insurance leaves the lender's security unprotected. Escrow makes sure both bills are paid on time, every time.
Escrow is not a fee and not a charge for a service. Every dollar collected is either paid out to your tax authority, your insurer or your mortgage insurer, or held as the small cushion the law allows. When the loan ends, whatever is left in the account comes back to you.
What Your Escrow Account Pays For
Most escrow accounts cover the same short list of bills. Anything outside it — repairs, utilities, HOA dues — is almost never escrowed.
| What escrow pays | How often it is paid | Who sets the amount |
|---|---|---|
| Property taxes | Once or twice a year, per your county | Your local tax authority |
| Homeowners insurance | Once a year, at renewal | Your insurer |
| Private mortgage insurance (PMI) | Monthly, with your payment | Your lender and PMI company |
| Flood insurance | Once a year, if required | Your insurer or the NFIP |
Property taxes are the largest item for most homeowners, and the one you control least: the county sets the assessed value and the tax rate. Homeowners insurance is the item you control most, because you choose the policy and can shop for a new one at renewal. PMI only appears while you owe it — on a conventional loan with less than 20% down — and it is collected through escrow until the PMI itself is removed. Our guide to what PMI is and how to remove it works through the 80% and 78% rules.
How Your Monthly Escrow Amount Is Calculated
The calculation is simple division. Your servicer adds up every bill it expects to pay from the account over the next twelve months, then divides by twelve. That monthly figure is the escrow portion of your payment.
| Escrow item | Yearly cost | Monthly share |
|---|---|---|
| Property taxes | $4,800 | $400.00 |
| Homeowners insurance | $2,400 | $200.00 |
| PMI | $1,800 | $150.00 |
| Total escrow | $9,000 | $750.00 |
That $750 is the escrow line on the monthly statement. It sits next to principal and interest, and together they make the full payment most borrowers call PITI — principal, interest, taxes and insurance — plus PMI while it applies. The servicer re-runs this calculation every year, so the figure moves whenever a tax bill or a premium moves.
Worked Example: A $400,000 Home
Take a $400,000 home bought with 10% down: a $360,000 loan at 7.24% fixed over 30 years. Monthly principal and interest is $2,453.39. Add the $750 of escrow from the table above and the full monthly payment is $3,203.39. Escrow is $750 of that $3,203.39 — about 23.4% of the payment — which is why a first-time buyer who planned only for principal and interest gets a shock at the first statement.
At closing you also fund the account with an initial deposit, because the first big bills arrive before twelve months of payments have built up. In this example the $2,400 insurance premium falls due in the first month, so the account would go $1,650 negative on monthly payments of $750 alone. The servicer therefore collects an initial deposit of $3,150 at closing: $1,650 to cover that early shortfall, plus the $1,500 cushion the law allows. That deposit is shown on your closing disclosure as a prepaid item.
Without PMI the same home costs less each month: taxes of $400 plus insurance of $200 is $600 of escrow, the yearly total is $7,200, and the maximum cushion falls to $1,200.
Where your $750 of monthly escrow goes — $400,000 home, $4,800 taxes, $2,400 insurance, $150 PMI.
The RESPA Cushion: Two Months, Maximum
On top of the bills themselves, your servicer may hold a cushion — a reserve against a bill arriving higher than expected or before enough payments have accumulated. The Real Estate Settlement Procedures Act (RESPA) caps that cushion at one-sixth of the estimated yearly payments from the account. One-sixth of a year is two months, so the cushion can never exceed two months of escrow payments: on the $9,000 yearly total in our example, $1,500 at most.
Two months is a ceiling, not a floor. Federal law does not require your servicer to hold any cushion at all, and your loan documents or your state may set a lower limit instead. Around a dozen states go further and require servicers to pay interest on the money held in escrow. If your statement shows a cushion above two months of escrow, that is worth a written question to the servicer: the cap is set by statute at 12 U.S.C. § 2609 and spelled out in Regulation X at 12 CFR 1024.17.
The Annual Escrow Analysis
Once every twelve-month computation year, your servicer must re-run the numbers in an escrow analysis and send you an annual escrow statement within 30 days of completing it. The analysis uses the aggregate method: a month-by-month trial balance that projects every payment in and every bill out, to find the lowest point the balance will reach.
Here is that trial balance for our example, with the $3,150 initial deposit, $750 a month in, a $2,400 insurance premium in month 1, and $2,400 of property tax in months 6 and 12:
| Month | Paid in | Paid out | Balance after |
|---|---|---|---|
| Start (closing deposit) | — | — | $3,150 |
| Month 1 — insurance due | $750 | $2,400 | $1,500 |
| Months 2–5 | $750 × 4 | $0 | $4,500 |
| Month 6 — first tax instalment | $750 | $2,400 | $2,850 |
| Months 7–11 | $750 × 5 | $0 | $6,600 |
| Month 12 — second tax instalment | $750 | $2,400 | $4,950 |
The lowest balance is $1,500 in month 1 — exactly the two-month cushion, because the $3,150 deposit was sized to make it so. The statement must itemise the expected bills, show the projected monthly balance, and explain any surplus or shortage. You also get an initial escrow statement within 45 days of settlement, showing the same breakdown for the first year.
Shortage, Surplus and Deficiency: What Happens Next
The annual analysis sorts every account into one of three outcomes. A surplus means the account holds more than the target balance plus the allowed cushion. If it is $50 or more and your loan is current, the servicer must refund it within 30 days of completing the analysis. A surplus under $50 may be refunded or credited toward next year's escrow payments.
A shortage means the projected balance will fall short of what is needed, though the account stays positive. The repayment rule turns on size. If the shortage is less than one month's escrow payment, the servicer may leave it, collect it within 30 days, or spread it over at least 12 months. If it equals or exceeds one month's escrow payment, the servicer may not demand it as a lump sum: it must let you repay it in equal monthly amounts over at least 12 months. In our example, a $600 shortage is under one month's $750, so the servicer could ask for $50 a month over 12 months; a $900 shortage must be spread as $75 a month over 12 months.
A deficiency is the serious case: the account has actually gone negative, usually because the servicer paid a bill before enough money had accumulated. The servicer must perform an escrow analysis before seeking repayment of the amount it advanced.
What Happens When Your Taxes or Insurance Rise
A fixed mortgage rate fixes only principal and interest. Taxes and insurance can rise every year, and when they do, your total monthly payment rises with them — even on a fixed-rate mortgage. This is the most common reason a payment that felt settled suddenly jumps.
Run the numbers on our example. Suppose the county reassesses the home and taxes rise from $4,800 to $5,400 a year, while the insurance renewal rises from $2,400 to $2,700. The new yearly escrow total is $5,400 plus $2,700 plus $1,800 of PMI — $9,900, or $825 a month. Principal and interest stay at $2,453.39, so the full payment moves from $3,203.39 to $3,278.39, an increase of $75 a month. On top of that, the year the bills rise, the account may also show a shortage from the months already paid at the old rate.
You have two levers when this happens. On taxes, check the assessed value on your county notice: if it is higher than comparable homes nearby, most counties let you appeal the assessment. On insurance, shop the renewal every year — the same cover from another carrier is often hundreds of dollars cheaper, and your servicer must accept any policy that meets the loan's requirements.
Can You Waive Escrow and Pay Taxes Yourself?
On a conventional loan you can ask, but the answer is the lender's to give. Fannie Mae's servicing guide sets the conditions, and your servicer must deny the request if any of them fails: your loan balance must be below 80% of the home's original appraised value — 20% equity measured against the original value, not a new appraisal — with no late payment in the past 12 months and no payment 60 or more days late in the past 24 months. The lender must also consider whether you can handle lump-sum tax and insurance bills; equity alone is not enough.
Expect a fee. Fannie Mae and Freddie Mac build a 0.25% loan-level price adjustment into waived loans — $900 on a $360,000 loan, typically paid at closing or rolled into the rate. Some servicers charge a smaller flat fee instead, and some charge nothing, so ask before you assume. A waiver is also blocked outright in several situations: loans that still carry borrower-paid PMI cannot have escrow waived for those premiums; FHA and USDA loans do not allow escrow waivers at all; a higher-priced mortgage loan must keep escrow for at least five years from closing under Regulation Z; and Fannie Mae bars a waiver when a property tax payment falls due within the next 45 days.
Waiving escrow trades a monthly routine for a yearly discipline. Without it, you must set aside the tax and insurance money yourself and pay bills of several thousand dollars on time. Miss a tax deadline and the county can lien the home; miss an insurance renewal and the servicer can buy force-placed insurance for you, which costs more and covers only the lender.
Escrow When You Refinance or Pay Off the Loan
Refinancing closes the old escrow account. When the new loan pays off the old one, the old servicer closes the account and refunds whatever balance is left, usually within 30 days of payoff, by check to the address on file — so make sure that address is current. The new loan usually opens a new escrow account, funded with a fresh deposit at closing. The refund and the new deposit happen separately, so plan for a short overlap.
The same logic applies at payoff. When the mortgage is paid off in full, the servicer returns the escrow balance, generally within 20 days, and if you refinance with the same servicer it may apply the balance to the new escrow account with your permission.
Escrow at Closing Is a Different Thing
One common confusion is worth clearing up. The "escrow" in a home purchase — the escrow company that holds your earnest money between offer and closing — is a different arrangement from the mortgage escrow account in this article. Purchase escrow is a neutral third party holding funds until the sale completes; mortgage escrow is your servicer holding your money after closing to pay taxes and insurance.
6 Common Escrow Mistakes
1. Budgeting for principal and interest only. Escrow is about 23% of the payment in our example. Work out the full PITI figure before you offer, using the county tax rate and a real insurance quote.
2. Ignoring the annual escrow statement. It shows whether your account is on course. A shortage ignored this year becomes a higher payment next year.
3. Assuming a fixed rate means a fixed payment. The rate fixes principal and interest. Taxes and insurance move, and the payment moves with them.
4. Letting insurance auto-renew without shopping. A fresh quote at renewal is the easiest way to hold the escrow figure down.
5. Missing the PMI connection. Escrow collects PMI while you owe it, and PMI cannot be waived out of escrow while it applies. Removing PMI cuts $150 a month in our example.
6. Refinancing without planning the overlap. The new escrow deposit is due at closing and the old refund arrives later.

Frequently Asked Questions
Is escrow required on every mortgage?
No. FHA and USDA loans require escrow for the life of the loan, and conventional loans usually require it when the down payment is under 20%. Higher-priced mortgage loans must keep escrow for at least five years. On a conventional loan with 20% equity or more, you can ask for a waiver, but the lender decides.
Does escrow increase my mortgage payment?
Escrow adds no charge of its own — it collects the bills themselves in monthly instalments. Your payment is higher than principal and interest alone because taxes and insurance are included in it. In our example the $750 of escrow is $400 of tax, $200 of insurance and $150 of PMI.
Can my servicer hold as much escrow cushion as it wants?
No. RESPA caps the cushion at one-sixth of the estimated yearly payments from the account — two months of escrow. On a $9,000 yearly total the maximum cushion is $1,500. Some states set a lower cap, and around a dozen states require servicers to pay interest on escrow balances.
What happens to my escrow money if I refinance?
The old account closes when the old loan is paid off, and the servicer refunds the remaining balance, usually within 30 days. The new loan opens a new escrow account funded with a deposit at closing. The refund and the new deposit happen separately, so expect a short overlap.
Why did my mortgage payment go up if I have a fixed rate?
The fixed rate fixes principal and interest only. If property taxes or insurance premiums rise, the escrow portion rises and the total payment rises with it. In our example a $600 tax rise and a $300 insurance rise lift the payment by $75 a month, from $3,203.39 to $3,278.39.
Can I pay my property taxes with a HELOC instead of escrow?
If your loan has no escrow account, you pay taxes yourself and could use any funds you choose, including a home equity line of credit — but borrowing to pay a tax bill means paying interest on a bill you could have covered from savings. Our guide to what a HELOC is explains how the credit line works.
