What Is an Escrow Account and How Does It Work?
Last updated September 2026
Quick answer
Your mortgage escrow account collects a slice of your property tax and homeowners insurance every month, then pays those bills for you when they're due — so you never face one giant annual tax bill. On a $400,000 home with $4,400/year in property tax and $1,500/year in insurance, that's about $492/month added to your principal and interest. It's also the reason a "fixed-rate" payment can still go up: your rate is fixed, but your tax and insurance costs aren't.
The example we'll use throughout
| Annual property tax | $4,400 |
|---|---|
| Annual homeowners insurance | $1,500 |
| Total annual escrow items | $5,900 |
| Monthly escrow payment | $491.67 |
| Cushion collected at closing (2-month max, by law) | $983.33 |
This $491.67 gets added on top of your principal and interest every month — it's not extra profit for the lender, it's simply your own tax and insurance bills, divided into monthly installments and held until due.
Why a "fixed" payment can still rise
Say next year your property tax rises to $4,800 and your insurance renews at $1,650:
New annual total: $4,800 + $1,650 = $6,450
New monthly escrow: $6,450 ÷ 12 = $537.50
Increase: $537.50 − $491.67 = $45.83/monthIf the account also ran short during the year — because the previous estimate was too low — your servicer typically spreads that shortage across the next 12 months too, adding to the increase (or lets you pay the shortage as a lump sum instead). Your principal and interest never moved. Your total monthly payment still went up. This is the single most common reason people are surprised by a payment change on a fixed-rate loan.
Escrow shortages and surpluses
- Shortage — taxes or insurance came in higher than estimated. Your servicer covers the gap, then recovers it from you, usually spread over the following year.
- Surplus — the account collected more than it needed. If the extra is more than $50, federal rules require your servicer to refund it to you, typically as a check after the annual escrow analysis.
Can you skip escrow?
Sometimes. FHA, VA, and USDA loans require escrow essentially without exception. Conventional loans sometimes allow you to waive it — usually only with 20%+ equity and strong credit, and sometimes for a small fee or a slightly higher rate. Waiving escrow means you become responsible for paying property tax and insurance directly, in full, when due — a real budgeting risk if you're not disciplined about setting the money aside yourself.
A different kind of "escrow"
Before you own the home, "escrow" usually means something else entirely: a neutral third party holding your earnest money deposit during the purchase process until closing, when it's applied toward your down payment or closing costs. Once you close and start making mortgage payments, "escrow account" refers to the ongoing tax-and-insurance account described above — a completely separate thing with the same name.

MortMetrix separates your principal-and-interest trajectory from your escrow estimate, so you can see clearly which part of a payment change came from your loan and which came from taxes or insurance.

Frequently asked questions
Why did my mortgage payment go up if I have a fixed rate?
Your principal-and-interest amount stays fixed, but the escrow portion covering property tax and insurance can change every year based on actual costs. This is the most common reason a "fixed" payment isn't perfectly flat year to year.
Can I opt out of an escrow account?
Sometimes, usually only on conventional loans with 20%+ equity and good credit, and sometimes for a fee or slightly higher rate. FHA, VA, and USDA loans almost always require it.
What happens if there's extra money in my escrow account?
If the surplus is more than $50, federal rules require your servicer to refund it to you, typically as a check after your annual escrow analysis.
Is escrow during the home-buying process the same as a mortgage escrow account?
No. Earnest money escrow is a temporary, neutral-party holding arrangement used only during the purchase, before closing. A mortgage escrow account is the ongoing tax-and-insurance account that exists for as long as you have the loan and escrow requirement.
How large can the escrow cushion be?
Federal rules (RESPA) cap the cushion collected as a buffer at two months' worth of escrow payments.
