Your mortgage payment may be much more than principal and interest. If your loan includes an escrow account, the servicer also collects money each month for property taxes and homeowners insurance. To calculate mortgage escrow, estimate those annual bills, divide by 12, and add the monthly result to your principal-and-interest payment. Your first escrow payment can be higher because lenders commonly collect an initial reserve at closing.
For a quick estimate, use this formula:
Monthly escrow = (annual property taxes + annual homeowners insurance + required flood insurance, if any) ÷ 12
For example, if annual property taxes are $3,600 and homeowners insurance is $1,800, the basic monthly escrow amount is $450:
($3,600 + $1,800) ÷ 12 = $450
That $450 is added to your monthly mortgage payment. It is not interest, and it does not reduce your loan balance. It is money held for upcoming tax and insurance bills.
What Mortgage Escrow Covers
An escrow account is a separate account managed by your mortgage servicer. The servicer collects a portion of estimated property-related expenses with each payment, then pays those bills when due. Most escrow accounts cover property taxes and homeowners insurance. Depending on the property and loan requirements, they may also include flood insurance, mortgage insurance, or other recurring assessments in limited situations.
Escrow is common on FHA, VA, and low-down-payment conventional loans. Some conventional borrowers with substantial equity may be allowed to waive escrow, depending on credit, loan-to-value ratio, property type, and lender guidelines. Waiving it means you pay tax and insurance bills directly, often in one or two larger installments each year.
For many buyers, especially first-time buyers, escrow makes budgeting easier. The trade-off is that your payment can change when taxes or insurance premiums change, even if your interest rate is fixed.
How to Calculate Mortgage Escrow Before You Buy
The most useful estimate starts with the actual property, not a statewide average. A lender can provide a preliminary estimate during pre-qualification, but the final amount depends on the home’s tax history, insurance quote, closing date, and servicing requirements.
1. Estimate annual property taxes
Start with the property’s most recent annual tax bill. Be careful with a home that was recently built, extensively renovated, or purchased after a long period of ownership. The prior owner’s tax bill may not reflect the assessed value after the sale.
In Arizona, property taxes can vary significantly by county, school district, special district, and assessed value. A newer home in Gilbert, Mesa, Queen Creek, or Chandler may have community development district charges or other assessments that affect the annual total. Do not assume a low prior tax bill will remain unchanged after closing.
If you do not have the exact bill, a rough planning method is to use the current bill and ask your loan officer whether a reassessment or new-construction estimate should be considered. The county assessor and title documents can provide useful context, but the loan estimate will use the lender’s projected figures.
2. Get a homeowners insurance quote
Use an actual insurance quote whenever possible. Premiums depend on the home’s replacement cost, roof age, claims history, deductible, location, coverage selections, and insurer. The purchase price is not the same as replacement cost, so insurance cannot be accurately estimated from the sales price alone.
For homes in areas with elevated weather, wildfire, or flood exposure, coverage costs may be materially higher. If the property is in a federally designated flood zone and the loan requires flood insurance, include that annual premium in the escrow calculation.
3. Add the annual costs and divide by 12
Suppose you are purchasing a home with these estimates:
| Escrow item | Annual estimate | Monthly amount | |—|—:|—:| | Property taxes | $4,200 | $350 | | Homeowners insurance | $2,160 | $180 | | Flood insurance | $0 | $0 | | Total escrow | $6,360 | $530 |
In this example, the ongoing monthly escrow estimate is $530. If your principal-and-interest payment is $2,400, your estimated payment before mortgage insurance or HOA dues is $2,930.
HOA dues are usually paid directly by the homeowner and are generally not included in mortgage escrow. Mortgage insurance may appear as a separate part of the monthly payment, depending on the loan program.
4. Account for the initial escrow deposit
The monthly amount is only part of the picture. At closing, lenders often collect funds to establish the account before the first tax or insurance bill comes due. The amount depends heavily on the closing month and the due dates for local property taxes and insurance renewals.
For example, a buyer closing shortly before a large property tax payment may need several months of tax reserves collected at closing. A buyer whose insurance premium is due immediately may also prepay the first year of coverage at closing. This is why the escrow section of a Loan Estimate and Closing Disclosure can look larger than the simple monthly calculation.
Federal servicing rules generally allow a limited escrow cushion, often up to two months of projected escrow payments, in addition to amounts needed for upcoming bills. Program rules vary, and the final figures come from the loan servicer’s schedule.
Why Your Escrow Payment Can Change
A fixed-rate mortgage fixes the interest rate, not every part of your total payment. Each year, the servicer performs an escrow analysis. It compares the amount collected with the actual or projected tax and insurance bills.
If your property taxes or insurance premium rose, the account may have a shortage. The servicer may give you the option to pay the shortage in a lump sum or spread it across future payments. Your monthly payment can also rise to collect enough for next year’s higher bills.
If the account has more money than required, you may receive an escrow refund or see a lower future payment. A refund does not necessarily mean your payment will stay lower. It depends on the new annual expense estimates and reserve requirement.
Common reasons for an increase include a property tax reassessment, the expiration of a homeowner exemption, higher insurance premiums, a new flood insurance requirement, or a prior estimate that was too low. Review the annual escrow statement rather than assuming a payment increase is an error.
Can You Pay Taxes and Insurance Yourself?
Sometimes. Whether you can remove escrow depends on your loan type, equity position, payment history, lender or servicer requirements, and state rules. FHA and VA loans commonly require escrow. Conventional loans may offer more flexibility after you meet certain requirements, but a waiver fee or higher pricing may apply.
Paying bills yourself gives you direct control over timing and can avoid monthly escrow adjustments. It also requires disciplined saving. A $6,000 annual tax-and-insurance obligation is effectively a $500 monthly expense whether it sits in your account or the servicer’s account.
For borrowers who prefer predictable monthly budgeting, keeping escrow can be the simpler choice. For homeowners with strong cash reserves and a preference for handling bills directly, an escrow waiver may be worth discussing.
Questions to Ask Before Closing
A clear escrow estimate should answer more than, “What is my payment?” Ask whether the tax amount is based on the current bill or a projected reassessment, whether the insurance figure comes from a quote, how many months of reserves are collected at closing, and whether mortgage insurance is included separately.
Also ask when the first escrow analysis will occur. New buyers are sometimes surprised when a first-year estimate changes after actual bills arrive. Knowing that possibility upfront helps you budget for a modest payment adjustment rather than treating it as an unexpected cost.
A mortgage broker can compare loan structures from multiple wholesale lending partners, but escrow requirements still depend on the specific program and lender. Price Mortgage can help borrowers review projected taxes, insurance, cash to close, and the full monthly payment before they commit to a loan.
The practical goal is not to predict every future tax or insurance change perfectly. It is to use realistic property-specific numbers, leave room in your budget for adjustments, and talk with one of our licensed loan officers when the estimate does not match the home or loan scenario you expect.
