What is an escrow account?
By David Chen · Published October 9, 2026
Ask most borrowers what their mortgage payment is and they will quote the loan payment. The amount actually leaving their account every month is usually larger, and a substantial part of it never touches the loan at all. That gap is the escrow account, and understanding it explains two things that otherwise look like errors: why a fixed-rate payment can rise, and why it can rise by more than the tax bill did.
The numbers below are one house: $400,000 with 20% down, so a $320,000 loan at 6.50% over 30 years, with property tax at 1.20% of the price a year and insurance at $1,800 a year.
The payment is two different things stapled together
| Component | Monthly | Share of the payment |
|---|---|---|
| Principal & interest | $2,022.62 | 78.62% |
| Property tax | $400.00 | 15.55% |
| Homeowners insurance | $150.00 | 5.83% |
| Escrow — tax plus insurance | $550.00 | 21.38% |
| Total monthly payment | $2,572.62 | 100% |
$320,000 at 6.50% over 30 years. Property tax at 1.20% of a $400,000 price and insurance at $1,800 a year, collected monthly. Produced by our calculator and independently recomputed.
The escrow line is 21.38% of the payment. It is worth sitting with that for a moment, because it changes the arithmetic of a mortgage in a way people rarely account for. Roughly a fifth of what you pay every month is not paying down the loan and is not interest — it is a tax bill and an insurance premium, arriving in instalments.
Nothing about that is harmful. It is arguably helpful: the alternative is finding $4,800 and $1,800 in single payments at unpredictable moments. What it does mean is that the escrow figure is not a fixed quantity, and it is not part of your rate. It is a forecast that gets corrected every year.
The annual cycle
In a normal year, the account does one full loop. Twelve monthly collections go in; the tax authority and the insurer take their payments out:
| Over twelve months | Amount |
|---|---|
| Collected across 12 monthly payments | $6,600 |
| Property tax paid out — usually in one or two instalments | $4,800 |
| Homeowners insurance paid out — usually one annual premium | $1,800 |
| Maximum cushion the servicer may hold | $1,100 |
Property tax at 1.20% of a $400,000 price and insurance at $1,800 a year. The cushion figure is the maximum the servicer may generally hold — typically one sixth of the annual disbursements, or two months — and it applies to the required balance rather than to what you are charged each month. Produced by our calculator and independently recomputed.
What you contribute across the year and what gets paid out are the same number, which is the point of the arrangement. The cushion is the part that surprises people: the servicer is generally permitted to hold a buffer above the year's bills so that a payment can be made when the bill arrives before the money to cover it has been collected. On these figures that buffer is up to $1,100.
What happens when the tax bill rises
This is where the escrow account produces the payment increase that does not match the tax increase. Suppose the assessment goes up 10%:
| Component | Before | After a 10% tax rise | Change |
|---|---|---|---|
| Property tax | $400.00 | $440.00 | +$40.00 |
| Insurance | $150.00 | $150.00 | — |
| Escrow total | $550.00 | $590.00 | +$40.00 |
| Total payment | $2,572.62 | $2,612.62 | +$40.00 |
Property tax rising 10% from $400.00 to $440.00 a month, insurance unchanged, on a $320,000 loan at 6.50% over 30 years. Produced by our calculator and independently recomputed.
That table is the settled position — the increase that applies once the account has adjusted. The first year is different, and this is the part almost nobody expects. The servicer pays the higher tax bill in full when it falls due, but your monthly collection was set from the old assessment. The result is a gap of $480 that has to be recovered, and servicing rules generally allow it to be spread across at least twelve months — which is another $40.00 a month.
So a 10% tax rise raises the payment $40.00 in the steady state, and $80.00 in the first year, taking it from $2,572.62 to $2,652.62 before falling back to $2,612.62. The same mechanism runs in reverse: if the assessment falls, the payment can drop, and the surplus is either refunded or credited rather than kept.
What the escrow figure is not
- It is not a fee. The servicer is collecting your own bills. Fees, if any, are separate line items and are disclosed separately.
- It is not part of the rate. Your 6.50% applies to the loan balance. It has nothing to do with the tax and insurance portion, which is why a fixed-rate loan can still have a rising payment.
- It is not affected by extra payments. Paying the loan down faster reduces the interest and can end mortgage insurance, but it does not change the tax or the insurance. The escrow half of the payment sits outside that entirely.
- It is not the same as the escrow used in a purchase. A purchase escrow holds the deposit and the paperwork until closing. An impound account holds tax and insurance money after closing. Two different arrangements, one word.
Where the figures come from, and how to check yours
- Property tax: your county assessor's record, not the estimate in an online listing. The rate varies enormously between jurisdictions and the assessed value may differ from the price you paid.
- Insurance: your own policy quote. This is the line most likely to move sharply, and unlike tax it is not capped by anything.
- The cushion: in your escrow account statement. The rules come from the CFPB's servicing regulations rather than from a general rule of thumb, so the statement is the place to read them.
- The loan payment itself: the mortgage calculator prices principal, interest, tax, insurance and mortgage insurance on your own numbers, and the amortization schedule shows how the principal and interest half of the payment changes over time — which, unlike the escrow half, is entirely predictable.
One related figure worth pinning down while you are here: whether mortgage insurance is part of the payment at all depends on your loan-to-value ratio, and it stops on a date you can calculate. How to remove PMI works through the timing, and how much down payment you need covers what each down payment level does to that line.
The short version
On a $320,000 loan at 6.50% the loan payment is $2,022.62 and the amount you actually pay is $2,572.62. The difference is $550.00 a month of tax and insurance, sitting in a pass-through account that pays your own bills once or twice a year. It is 21.38% of the payment and it is not fixed. When the tax bill rises 10%, the payment rises $40.00 in the steady state and $80.00 in the first year, because the shortfall the servicer covered has to be recovered on top of the new assessment. A fixed rate fixes the loan, not the payment.
Frequently asked questions
What exactly is an escrow account?
It is a holding account your mortgage servicer uses to collect and pay the property costs that sit outside principal and interest — most often property tax and homeowners insurance. On a $320,000 loan at 6.50% the principal and interest is $2,022.62 a month, and the escrow part is $550.00 of it. That $550 does not reduce the loan balance by a cent, and it is not a fee: it is your own tax and insurance bill, collected in monthly instalments instead of arriving as one large payment.
Is escrow the same thing as earnest money?
No, and the word is used for both. During a purchase, escrow describes a neutral third party holding the deposit and the documents until the sale completes. After completion, the same word usually describes the impound account that collects your tax and insurance. They are different arrangements that happen to share a name, and a question about one of them does not tell you anything about the other.
Why does my payment change if my loan is fixed?
Because part of your payment is not the loan. On this example $550.00 of the $2,572.62 goes to escrow, and both halves of that figure move when the tax assessment or the insurance premium changes. A fixed rate fixes the $2,022.62. It fixes nothing about the other $550, which is why a payment can rise on a loan whose rate cannot.
Why did my payment jump more than the tax increase?
Because the shortfall arrives as well as the increase. If the tax bill rises 10% mid-year, the servicer has already paid the higher bill out of an account funded at the old rate, leaving a $480 gap. Servicing rules generally allow that gap to be spread across at least twelve months, which adds $40.00 a month on top of the $40.00 increase — $80.00 in total for that year. The following year the payment falls back to the $40.00 increase.
Can I pay tax and insurance myself instead?
Sometimes, and the terms depend on the loan and the lender rather than on a general rule. Waiving escrow means you keep the $550 a month yourself and are responsible for a $4,800 tax bill and an $1,800 premium when they fall due, plus any penalties if they are late. Whether that is available, whether it costs anything, and whether it is wise all depend on your circumstances; your servicer is the right place to ask, and the CFPB material on escrow accounts is the right place to read about the rules.
