How It Works
How Escrow Accounts Work
Your lender collects a portion of property taxes and insurance each month and holds it in an escrow account, paying the bills when they come due.
Monthly Escrow Calculation
Monthly Escrow = (Annual Taxes + Annual Insurance + Annual PMI + Annual HOA) / 12
Escrow Cushion
Federal law (RESPA) allows lenders to maintain a cushion of up to 2 months of escrow payments to protect against increases.
PITI Explained
Your total monthly housing cost (PITI) is what lenders use to calculate your debt-to-income ratio.
Worked Example
Annual taxes $4,800, insurance $1,800, no PMI or HOA. P&I payment is $2,100. Lender requires 2-month cushion.
- 01Monthly tax escrow: $4,800 / 12 = $400
- 02Monthly insurance escrow: $1,800 / 12 = $150
- 03Monthly escrow collection: $400 + $150 = $550
- 04Total PITI: $2,100 + $550 = $2,650
- 05Annual escrow disbursements: $4,800 + $1,800 = $6,600
- 06Required cushion: $550 x 2 = $1,100
Frequently Asked Questions
Can I opt out of escrow?
Some lenders allow escrow waivers, usually requiring at least 20% equity and good payment history. There may be a fee (0.125-0.25% rate increase) for waiving escrow. FHA and VA loans generally require escrow.
What happens when escrow is short?
If your escrow account is short (actual costs exceeded collected amounts), the lender covers the shortage and increases your monthly escrow to repay it. By law, you can spread any shortage over 12 months.
Why does my mortgage payment change every year?
Annual escrow analysis adjusts your escrow payment based on actual tax and insurance bills. If taxes or insurance increase, your escrow (and total payment) increases. If they decrease, your payment may go down or you receive a refund.
