What it is
An escrow account — also called an impound account — is a fund your mortgage servicer holds to pay your property taxes and homeowners insurance on your behalf. Instead of you saving up for a big tax or insurance bill, a slice of each monthly mortgage payment goes into escrow, and the servicer pays those bills directly when they come due.
That’s why a monthly mortgage payment is often described as PITI: Principal, Interest, Taxes, and Insurance. The principal and interest repay the loan; the taxes and insurance flow through escrow.
How it works
- At closing, you typically prepay a few months of taxes and insurance to seed the account (part of the prepaid items you pay at closing).
- Each month, the servicer collects roughly 1/12 of your estimated annual taxes and insurance along with your principal and interest.
- When bills come due, the servicer pays the taxing authority and insurer from the account.
- Once a year, the servicer runs an escrow analysis: it reviews what it collected, what the bills actually were, and what they’re projected to be next year, then adjusts your monthly escrow portion.
Federal rules (administered by the CFPB) let servicers keep a modest cushion in the account but cap how large it can be, and require that annual analysis with a statement to you.
Why your payment changes
Your principal and interest usually stay fixed on a fixed-rate loan — but your total monthly payment can still change because taxes and insurance change:
- Property taxes rise (or occasionally fall) when your assessment or local tax rate changes.
- Homeowners insurance premiums change at renewal.
When those go up, the escrow portion of your payment goes up too, even though your loan didn’t change.
Shortages and surpluses
The annual escrow analysis can reveal:
- A shortage — the account collected less than the bills required (often because taxes or insurance rose). The servicer will typically raise your monthly escrow and may offer to spread the shortfall over 12 months or let you pay it as a lump sum.
- A surplus — the account collected more than needed. If the surplus is above a set threshold, the servicer generally refunds it to you; smaller surpluses may be credited toward next year.
Neither means an error occurred; they’re the normal result of estimating future bills.
A few practical notes
- Escrow is commonly required when your down payment is small, and may be optional (sometimes for a small fee) with more equity. Rules vary by loan type and lender.
- Escrow is separate from PMI, though both may appear in your monthly payment.
- If a payment jumps unexpectedly, the escrow analysis statement explains why — read it before assuming a mistake.
Bottom line
An escrow (impound) account bundles property taxes and homeowners insurance into your monthly payment, and the servicer pays those bills for you. Because taxes and insurance change over time, your total payment can move even on a fixed-rate loan, and the yearly escrow analysis reconciles any shortage or surplus. This is general education about how escrow works, not advice about your specific account.
