Use the numbers from your servicer's annual escrow account statement when you have them. If you do not know the official shortage yet, this calculator estimates one from projected escrow needs, current balance, and the required minimum cushion.

Methodology
Required annual escrow equals projected annual property tax plus homeowners insurance plus other escrowed items. The base monthly escrow amount is that annual total divided by 12.
If you enter an official shortage or surplus, the calculator uses it. Otherwise it estimates shortage as required annual escrow plus the required minimum cushion minus the current escrow balance and the next 12 months of current escrow collections. Positive values are shortages; negative values are surplus estimates.
Monthly repayment equals the shortage remaining after any lump-sum payment divided by the repayment period. The new total monthly escrow payment equals base monthly escrow plus monthly repayment. If you enter principal and interest, the all-in payment adds that amount.
Important caveats
- Your servicer's escrow analysis, annual escrow account statement, shortage notice, and payment change notice control the actual amount due.
- RESPA generally limits cushion amounts for many mortgage escrow accounts, commonly to two months of escrow payments, but state law, loan type, investor rules, and account history can affect the analysis.
- Tax bills, insurance renewals, flood insurance, mortgage insurance, special assessments, and supplemental tax bills can change after the statement date.
- Timing matters. A current balance snapshot may not match the servicer's projected low balance after scheduled disbursements and payments.
- A lump-sum payment usually reduces only the shortage repayment portion. It does not prevent the base escrow collection from rising when projected bills rise.
- Surplus refunds, shortage repayment options, escrow waivers, and optional lump-sum handling depend on the official servicer notice and applicable rules.

Frequently asked questions
Is an escrow shortage the same as a missed payment?
No. A shortage usually means the projected escrow balance is too low to cover upcoming escrowed bills and the required cushion. It can happen even when every mortgage payment was made on time.
Why can my payment rise if I pay the shortage?
Paying the shortage can remove the temporary repayment amount, but the base escrow portion can still rise because projected taxes, insurance, or other escrowed items increased.
What does a negative shortage mean?
A negative shortage is a simplified surplus estimate. Servicers have specific rules for surplus handling and may refund, credit, or retain small amounts depending on the analysis and applicable law.
Can I remove escrow instead?
Some loans allow escrow waivers after certain conditions are met, but many loans require escrow because of loan type, LTV, investor rules, flood insurance, prior delinquency, or state requirements.
