Escrow Account Calculator

What Is an Escrow Account?

An escrow account is a separate account managed by your mortgage servicer to collect and hold funds for recurring property-related expenses — most commonly property taxes and homeowners insurance. Each month, your servicer collects a portion of these annual costs alongside your principal and interest payment, then disburses them directly to your local tax authority and insurance provider when bills come due.

According to the Consumer Financial Protection Bureau (cfpb.gov), most conventional loans and all FHA, VA, and USDA loans require an escrow account. Even if escrow is not required, many borrowers opt in because it simplifies budgeting: instead of setting aside a large lump sum twice a year for property taxes, your servicer spreads the cost evenly across 12 monthly payments. The CFPB regulates escrow accounts under the Real Estate Settlement Procedures Act (RESPA), which sets clear limits on how much servicers can collect and hold.

How Escrow Payments Are Calculated

Your monthly escrow payment is simply the sum of your annual escrow obligations divided by 12, plus any cushion your lender is permitted to hold. Here is the formula used by this calculator, consistent with RESPA guidelines from cfpb.gov:

• Monthly property tax escrow = (Home value × annual tax rate) ÷ 12
• Monthly homeowners insurance escrow = Annual premium ÷ 12
• Monthly flood insurance escrow = Annual flood premium ÷ 12 (if applicable)
• Monthly HOA escrow = Annual HOA dues ÷ 12 (if collected through escrow)
• Total monthly escrow = Sum of all monthly components

Beyond the monthly payment, your lender typically requires an initial escrow deposit at closing to pre-fund the account. RESPA allows lenders to collect up to 2 months of escrow as a cushion (also called a "reserve") to protect against tax or insurance rate increases. On a $2,400/year tax bill and a $1,800/year insurance premium, the 2-month cushion equals $700 — a common line item on mortgage Closing Disclosure forms.

Your servicer is required by RESPA to perform an annual escrow analysis each year. If your account has a surplus of more than $50, the excess must be refunded to you or credited to your next payment. If there is a shortage, your servicer can require you to pay it back over 12 months or as a lump sum.

Escrow Shortages and Surpluses

Escrow shortages and surpluses are extremely common because property tax assessments and insurance premiums change year to year. If your city raises the property tax rate mid-year, your escrow account may not have collected enough to cover the increased bill. Your servicer will detect this during the annual analysis and notify you of a shortage — along with a new, higher monthly payment to cover both the deficit recovery and the updated annual estimate.

Common causes of escrow shortages include:

• Rising property tax assessments: Home values have increased significantly in many markets since 2020, often triggering reassessments that push annual tax bills higher. A $50,000 increase in assessed value at 1.1% adds $550/year to your tax bill — or about $46/month to your escrow.
• Insurance premium increases: Homeowners insurance costs have risen sharply in disaster-prone states. Rate increases between 20-40% in Florida, California, and Louisiana are common, often creating multi-hundred-dollar annual shortages.
• Flood insurance reclassification: If FEMA updates flood zone maps and reclassifies your property into a Special Flood Hazard Area (SFHA), mandatory flood insurance will be added to your escrow — often with little warning.

If your escrow analysis shows a surplus of more than $50 above the required cushion, your servicer must refund the excess within 30 days.
