Why did my mortgage payment change?

Start with your old and new payment. We’ll help you work through what changed.

Your monthly payment
Just two numbers to start. Nothing else is required yet.
No email needed to use the tool. Your calculation stays in this browser unless you choose to email the breakdown.

Next, let’s work out where that change came from.

Open only the groups you know. Blank stays unknown. If a known amount was actually zero, enter 0.

Principal + interest Not added

This is the base loan-payment component before escrow, mortgage insurance and other additions.

Where do I find this?

Look at the payment breakdown on your monthly mortgage statement. If your principal and interest amount changed on a fixed-rate loan, check for a temporary buydown ending, a loan modification, or another loan-specific change.

Property taxes Not added

Use the annual tax bill, not appraised value.

If you know the tax amount was $0, enter 0. Otherwise leave it blank.
Where do I find this?

Use the annual amount on your county tax bill or your servicer’s escrow analysis. If you pay property taxes directly, a tax change affects your household cost but is not attributed to the mortgage payment here.

Homeowners insurance Not added

Use the annual premium from the policy renewal or declarations page.

If you know the premium was $0, enter 0. Otherwise leave it blank.
Where do I find this?

Use the annual premium on the policy renewal or declarations page. If you pay insurance directly, the premium can change your household cost without changing the payment sent to your mortgage servicer.

Escrow shortage repayment Not added

This is the monthly amount specifically being collected to repay a prior escrow shortage. Compare the old repayment with the new repayment.

Where do I find this?

Look at the annual escrow analysis for language such as shortage, deficiency, repayment, or spread over 12 months. Do not enter the total shortage balance if the tool is asking for the monthly repayment amount.

Other payment changes Not added

Use this for monthly mortgage insurance or another recurring item collected with the mortgage.

What this tool is doing

One payment can move for several different reasons.

Recurring costs

If taxes or insurance are escrowed, annual bill changes can change the monthly amount your servicer collects.

Temporary shortage repayment

A prior escrow shortfall can add a separate repayment amount. That is different from the new ongoing monthly need.

Loan or other changes

Principal and interest, mortgage insurance, fees, or other loan-specific items can also move the payment.

Worked example

A $160 increase can contain two very different kinds of change.

This example is intentionally simple. It shows why recurring cost and temporary shortage repayment should not be lumped together.

Before vs. now
Total payment$2,340 → $2,500
Escrowed taxes+$60/mo
Escrowed insurance+$50/mo
Shortage repayment$20 → $70
How to read it
Ongoing tax + insurance change+$110/mo
Change in shortage repayment+$50/mo
Difference still to reconcile$0/mo

The full $160 increase is real, but only $110 of it is the recurring tax-and-insurance change in this simplified example. The extra $50 is shortage repayment.

Austin-area tax bills

Check the bill your escrow analysis is trying to pay.

Use the official county source for the actual tax bill or payment history. Appraised value is not the same thing as the tax amount due.

FAQ

Questions homeowners usually ask next.

Why did my mortgage payment go up if I have a fixed interest rate? +
A fixed interest rate usually keeps principal and interest stable, but the total payment can still change if escrowed property taxes, escrowed homeowners insurance, mortgage insurance, a shortage repayment, fees, or another loan-specific component changes.
Can my mortgage payment go down when taxes or insurance go down? +
Yes, if those expenses are paid through escrow and the servicer recalculates a lower required escrow amount. The exact payment still depends on the servicer’s escrow analysis and any shortage, surplus, cushion, or other payment component.
What is an escrow shortage? +
An escrow shortage means the escrow account has less money than the servicer determines it needs under the annual analysis. A servicer may collect additional money to repay that shortage. The monthly shortage-repayment amount is separate from the new ongoing escrow amount.
Why does this tool ask whether my mortgage company pays taxes and insurance? +
Because a tax or insurance bill can affect your household budget without affecting the mortgage payment. This tool attributes those bills to the mortgage payment only for periods when they are paid through escrow.
Why can’t the tool explain every dollar of my payment change? +
Your servicer’s payment can include items this tool cannot infer, including changes in principal and interest, mortgage insurance, fees, force-placed insurance, escrow-cushion calculations, or servicing errors. The remaining difference is meant to show you what still needs to be reconciled.
What should I do if the payment still does not make sense? +
Compare the payment breakdown on the monthly statement with the annual escrow analysis. If the numbers still do not reconcile, contact the mortgage servicer and ask for an explanation of the specific components that changed.
