Do Banks Make Money Off Your Escrow Account?
Not directly. Banks don't earn interest from your escrow balance, they just use it to pay your taxes and insurance.

What matters for closing is that escrow doesn't change what you owe for homeowners insurance, only how it gets paid. Your lender will ask for proof of coverage and a binder before the loan funds, then build your annual premium into the monthly mortgage payment along with property taxes. The lender holds that money and pays the insurer directly when the bill comes due. So the policy you pick, the dwelling coverage amount and the deductible, is still yours to choose. Escrow just automates the payment, it doesn't change the price.
Since escrow just pays whatever premium your policy carries, the amount itself is still worth getting right before closing. A lower premium means a smaller monthly escrow payment for as long as you own the house. Comparing policies now, while you're choosing dwelling coverage and a deductible anyway, is the only point where the price is actually in your hands.
How does the lender decide how much to collect for escrow?
At closing, the lender estimates a year of property taxes and a year of homeowners insurance, then divides that total by twelve to set the monthly escrow payment. Lenders also usually collect a cushion upfront, often two to three months' worth, so there is a buffer in the account before the first bills come due. That cushion is not a fee the lender keeps. It sits in the escrow account and counts toward future payments.
Once a year, the lender runs an escrow analysis. They compare what actually went out for taxes and insurance over the past twelve months to what they collected. If the homeowners premium went up at renewal, or the property got reassessed for taxes, the account can come up short. The lender usually offers two ways to handle a shortage. Pay it in one lump sum, or spread it across the next year's payments, which raises the monthly mortgage payment. The reverse happens too. A lower premium or a lower tax bill than estimated can mean a refund or a smaller payment going forward.
The policy chosen before closing matters beyond that first binder because of this yearly reset. The premium locked in becomes the baseline the lender uses to calculate escrow, and it stays the basis until the next renewal changes the number. A policy that looks fine at closing but renews at a much higher rate shows up a year later as a shortage notice and a higher mortgage payment, not just a surprise bill from the insurer.
None of this changes who sets the premium or who to talk to about raising or lowering coverage. The lender administers the account and pays the bills on schedule. The insurance company sets the price based on the dwelling coverage, deductible and other terms on the policy itself. When a mortgage payment changes, the escrow analysis will say whether taxes or insurance drove it, so it is worth reading rather than assuming.
What happens if there isn't enough in escrow when a bill comes due?
If a tax or insurance bill arrives and the escrow account doesn't have enough to cover it, the lender typically pays it anyway and lets the account go negative, rather than letting the policy lapse or the taxes go delinquent. That's the main point of escrow from the lender's side. A missed homeowners payment could mean a lapse in coverage on their collateral, and a missed tax payment can lead to a lien, so lenders front the shortfall and recover it later through the next escrow analysis.
Paying a bill out of a negative balance is different from a shortage found during the annual review, which spreads the catch-up across future payments or asks for a lump sum. Covering a bill in real time usually happens because a premium or tax bill came in higher than what the last analysis assumed. It's one more reason the premium picked before closing matters past the first year. A policy that renews higher than expected can create this kind of gap before the next scheduled review catches up to it.
New homeowners sometimes assume the lender checks in before every payment to make sure the math still works, but the account mostly runs on the yearly schedule. Between analyses, the lender pays what's billed and adjusts afterward. Reading the annual escrow statement is the only real way to see whether the account is tracking the way it should, since it shows what was collected, what went out, and whether the running balance matches the lender's projections.
None of this is a reason to accept a higher premium at renewal without checking. The insurance side of escrow is just whatever the policy costs, so shopping for a lower premium at renewal has the same effect it did at closing. It lowers what the lender needs to collect, which shows up as a smaller monthly payment the next time the account resets, instead of a shortfall to make up later.
Before closing, check the premium going into escrow
Your declarations page shows the dwelling coverage and deductible the lender will base escrow on. Comparing that premium now, before it sets a year of monthly payments, is worth more than comparing after renewal.
