Escrow Shortage: Why Your Mortgage Payment Went Up

The short version

If your mortgage payment went up even though your rate is fixed, the cause is almost always your escrow account: the part of your payment that covers property taxes and homeowners insurance. When those bills rise faster than your lender expected, your account comes up short, and your payment goes up to catch up.

Three things to know:

1. Your payment usually rises for two reasons at once: a catch-up for last year’s shortage, and a higher amount for next year’s bills.
2. Paying the shortage in one lump sum usually isn’t worth it. Servicers don’t typically charge interest on a shortage spread over 12 months; your escrow statement shows the exact amount.
3. The only way to truly lower the payment is to lower the bills themselves: your insurance premium or your property taxes.

How escrow works

If you have an escrow account, your lender (more precisely, your loan servicer, the company you send payments to) collects a little extra each month on top of your principal and interest. It holds that money and pays your property tax and insurance bills when they’re due.

The servicer has to estimate those bills a year in advance. Once a year, it runs an escrow analysis: it compares what it collected with what it actually paid, and estimates the coming year’s bills. Federal rules (known as Regulation X) also let the servicer keep a cushion of up to one-sixth of a year’s escrow payments, about two months’ worth, in case bills come in higher than expected.

Why so many payments are going up

Property taxes and homeowners insurance premiums have both risen quickly in recent years, faster than many servicers’ estimates. Cotality, a property data firm, estimated that the average homeowner’s mortgage payment would rise about $175 a month in 2026 because of these costs. According to a Neighbors Bank study reported in July 2026, taxes and insurance made up 21% of the average monthly mortgage payment.

When last year’s estimate was too low, two things happen at your annual analysis:

• A shortage: the account doesn’t have enough to cover the coming year’s bills plus the cushion.
• A higher monthly escrow amount: the servicer raises its estimate for next year so the shortage doesn’t happen again.

That’s why the jump often feels bigger than the actual increase in your bills. You’re paying for next year’s higher bills and catching up on last year’s at the same time.

A worked example

Say your taxes and insurance used to total $6,000 a year, so you paid $500 a month into escrow. This year, the bills came in higher, and your servicer now projects $7,200 for the coming year, or $600 a month. Your analysis also shows a shortage of $1,400.

Option 1: spread the shortage over 12 months. $1,400 ÷ 12 = about $117 a month. Your escrow payment becomes $600 + $117 = $717 a month for the next year, then drops to $600 once the shortage is paid off.

Option 2: pay the shortage in one lump sum. You pay $1,400 now, and your escrow payment becomes $600 a month.

Either way, your monthly escrow goes from $500 to at least $600, because the bills themselves went up. The lump sum only changes how you pay the $1,400 catch-up, not the total.

Should you pay the shortage in a lump sum?

Usually, no. Here’s the honest math: escrow accounts generally pay you no interest. Servicers don’t typically charge interest on a shortage spread over 12 months; your escrow statement shows the exact amount. So paying $1,400 today instead of $117 a month means giving up money you could keep in a savings account earning interest in the meantime.

A lump sum makes sense in two situations:

• You’d rather have the lower monthly payment and you have the cash sitting idle anyway.
• Your budget is tight month to month, and a smaller fixed payment is easier to plan around than a temporary bump.

What the rules say: if the shortage is less than one month’s escrow payment, your servicer can ask you to pay it within 30 days. If it’s larger, federal rules don’t let the servicer demand it all at once; it can spread the shortage over at least 12 months. Most servicers also let you pay the shortage in one payment if you prefer; ask yours.

How to actually lower your escrow payment

Since the payment follows your bills, lowering the bills is the only lasting fix.

1. Shop your homeowners insurance. Get quotes from at least three insurers. Ask about raising your deductible and about discounts for bundling, a new roof, or a security system. If you switch, make sure your old insurer refunds any unused premium to you.
2. Appeal your property tax assessment. Check your assessment notice for errors, like the wrong square footage. Compare your assessed value with recent sales of similar homes. Counties set yearly deadlines for appeals, so check your county assessor’s website.
3. Claim every exemption you qualify for. Many states offer a homestead exemption for your primary home, plus exemptions for seniors, veterans, and people with disabilities. These aren’t always applied automatically.
4. Remove private mortgage insurance if you can. If your escrow includes private mortgage insurance (PMI), and your balance has dropped to 80% of your home’s original value, you can ask to cancel it. See the PMI removal calculator.
5. Ask for a new escrow analysis after any change. If your insurance or tax bill drops, send the new bill or policy to your servicer and ask them to rerun the analysis. Otherwise, the lower payment may not show up until next year’s review.

Check your escrow statement for errors

Servicers make mistakes. When you get your annual escrow statement, compare the “expected” and “actual” columns, and check that:

• the tax amount matches your county’s bill
• the insurance premium matches your current policy, and your servicer isn’t still paying an old policy you canceled
• no bill was paid twice

If you find an error, send your servicer a written notice of error. Under federal rules, servicers must acknowledge it and investigate.

What about getting rid of escrow?

Some homeowners respond to a shortage by asking to drop escrow and pay taxes and insurance themselves. That’s possible on many conventional loans once you have at least 20% equity, but it doesn’t make the bills any smaller. It only changes who holds the money until the bills are due. If you’re comfortable saving for those bills on your own, it can earn you a little interest; see how escrow works and when you can choose it.

Frequently asked questions

Why did my mortgage payment go up if I have a fixed rate? A fixed rate locks in your principal and interest. The taxes and insurance collected through escrow can still change every year. When they rise, your total payment rises, even though your interest rate hasn’t changed.

Is it better to pay an escrow shortage all at once? Usually not. Servicers don’t typically charge interest on a shortage spread over 12 months; your escrow statement shows the exact amount. Paying it all at once mainly gives up cash you could keep in savings. Pay it at once only if you prefer the lower monthly payment and the cash isn’t needed elsewhere.

What if my escrow account has a surplus? If the analysis finds a surplus of $50 or more and your payments are current, your servicer must refund it to you within 30 days of the analysis. Smaller surpluses can be credited toward next year’s payments.

Can my servicer make me pay a shortage in a lump sum? Only if the shortage is less than one month’s escrow payment. For larger shortages, the servicer can’t require a lump sum; it can spread the shortage over at least 12 months. Most servicers also let you pay the shortage in one payment if you prefer; ask yours.
