What is the Escrow Shortage & Mortgage Predictor?
The Escrow Shortage & Mortgage Payment Predictor helps homeowners estimate changes in their monthly mortgage payments when property taxes or homeowners insurance rates rise. When an annual escrow analysis statement reveals a shortage, your lender recalculates your monthly payment. This tool clarifies that math, showing how a tax hike affects both your base monthly escrow and your shortage repayment, helping you choose whether to pay the deficit as a lump sum or spread it over 12 months.
How Does the Escrow Shortage & Mortgage Predictor Work?
1. Enter Current Monthly P&I â The portion of your mortgage payment that goes only toward principal and interest.
2. Enter Current Monthly Escrow â The monthly portion currently allocated for property taxes and home insurance.
3. Input New Annual Tax & Insurance â Enter your newly assessed annual property tax bill and annual homeowners insurance premium.
4. Input Known Shortage (Optional) â If you already have your escrow analysis statement, enter the exact shortage amount. If left at $0, the tool will estimate it for you.
5. Analyze Repayment Scenarios â Compare your options: spreading the shortage repayment over 12 months vs. paying the lump sum upfront.
Formula & Calculation Method
New Base Monthly Escrow:
New Monthly Escrow = (New Annual Property Tax + New Annual Insurance) / 12
Estimated Escrow Shortage:
If not stated, the shortage is estimated as the monthly escrow deficit multiplied by 12:
Shortage = (New Monthly Escrow - Current Monthly Escrow) Ã 12
Option A: Spread Shortage over 12 Months:
Monthly Repayment = Shortage / 12
New Monthly Mortgage Payment = Principal & Interest + New Monthly Escrow + Monthly Repayment
*Note: After 12 months, the payment drops back down to (P&I + New Monthly Escrow).*
Option B: Pay Shortage as Lump Sum:
One-Time Payment = Shortage
New Monthly Mortgage Payment = Principal & Interest + New Monthly Escrow
Example Calculation
Example: P&I of $1,500, Current Escrow of $400 ($4,800/yr), New Annual Tax of $4,800, New Annual Insurance of $1,800 ($6,600/yr total), No Known Shortage
- New Monthly Escrow = ($4,800 + $1,800) / 12 = $550
- Monthly Escrow Deficit = $550 - $400 = $150
- Estimated Shortage = $150 Ã 12 = $1,800
- Monthly Shortage Repayment = $1,800 / 12 = $150
- Option A (Spread): $1,500 + $550 + $150 = $2,200/mo for year one (rises by $300, double the actual tax increase).
- Option B (Lump Sum): Pay $1,800 upfront. New payment = $1,500 + $550 = $2,050/mo (rises by $150).
