Escrow Payment Calculator

An escrow or impound account is the servicer collecting your property tax and insurance in twelve pieces and paying the bills when they fall due. It is not an extra cost. It is the same money, collected earlier, held by someone else.

What confuses borrowers is the annual analysis. Tax assessments and insurance premiums change, the servicer recalculates, and the payment moves - sometimes sharply, because a shortage from the past year is collected on top of the new higher monthly amount. This calculator separates those two effects so an increase can be read rather than guessed at.

Monthly escrow payment

$600

Monthly escrow while a shortage is repaid: $600
Tax portion: $450
Insurance portion: $150
Required cushion: $1,200
Shortage: $0
Surplus: $800
Shortage repayment per month: $0
Total escrowed per year: $7,200

Escrow is not a cost in itself. It is the same tax and insurance bills collected monthly instead of annually, held by the servicer and paid on your behalf.

The account is above the required cushion. Federal rules require surpluses over a threshold to be refunded rather than held.

Escrow amounts change every year because tax assessments and insurance premiums change. An increase in the escrow portion is not an increase in your interest rate.

A routine escrow account with a two-month cushion

$5,400 tax, $1,800 insurance, $2,000 currently held.

Monthly escrow payment: $600
Required cushion: $1,200
Surplus: $800

An account short after a tax increase

$7,200 tax, $2,400 insurance, only $600 held.

Monthly escrow payment: $800
Monthly escrow while a shortage is repaid: $883
Shortage: $1,000

Why the payment jumped more than the tax did

When an assessment rises, two things happen at once. The monthly escrow rises to cover the new annual bill, and the account is short for the year that has already passed, because it collected at the old rate while paying at the new one.

The shortage is normally spread across twelve months on top of the new amount. That is why a modest tax increase can produce a payment increase that looks disproportionate - and why the payment usually falls again a year later once the shortage has cleared.

The cushion is capped

Servicers are permitted to hold a reserve, commonly around two months of escrow payments, so that a bill arriving early does not overdraw the account. They are not permitted to hold unlimited amounts, and a surplus above the allowed threshold must be refunded rather than retained.

If a statement shows a large surplus being held rather than returned, that is worth questioning.

Paying a shortage as a lump sum

Most servicers offer both options. Paying the shortage in one payment avoids the twelve-month increase but requires the cash immediately. Spreading it costs nothing extra in interest, since a shortage is not a loan - it is simply money owed to your own account.

The choice is therefore about cash flow rather than cost, which is a rarer situation in lending than it sounds.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

The base monthly escrow is the annual escrowed items divided by twelve.
The required cushion is the monthly escrow multiplied by the cushion months you enter.
A shortage is the difference between the required cushion and the current balance, spread across the number of months you specify.
Servicer practice and the permitted cushion are governed by federal rules and by the loan documents; this is arithmetic on your figures, not a statement of what a particular servicer will do.

Frequently asked questions

Can I cancel escrow?

Sometimes, usually once the loan is below a certain loan-to-value and the payment history is clean. Some loan programmes require escrow permanently. Ask the servicer for the conditions in writing.

Does escrow money earn interest?

In most states, no. A few require servicers to pay interest on escrow balances. It is set by state law rather than negotiable.

Why did my escrow rise when my rate is fixed?

Because the fixed part of the payment is principal and interest only. Tax and insurance are re-estimated every year and are not fixed by the note.

What is an escrow surplus refund?

Money collected beyond the allowed cushion. Above a threshold set by federal rules it must be refunded to you rather than credited or held.
