Mortgage servicing, clearly explained
Your rate can stay fixed. Your payment can still change.
We turn escrow statements, servicing rules, tax changes and insurance jumps into plain-English guides, decision tables and calculators for U.S. homeowners.
Escrow shortage calculator
Trace the increase before you choose how to pay it.
Planning estimate from the increase in annual property-tax and homeowners-insurance bills: $1,440. Your servicer's actual shortage can differ because Regulation X analysis uses account balance, disbursement timing and any permitted cushion.
Spread shortage over 12 months
$2,640/mo+$170 vs. currentPay shortage in full now (if your servicer accepts it)
$2,520/mo+$50 vs. currentIllustrative planning tool, not a reproduction of your servicer's aggregate escrow analysis. The auto-estimate uses the annual bill increase as a rough shortage proxy. Use the shortage on the official analysis when available. A lump-sum shortage payment is shown only as a comparison; confirm that your servicer accepts that option. Loan terms, account balance, disbursement timing and a permitted cushion can change the actual result.
Start with the problem you see
Mortgage questions are easier when you begin with the symptom.
You do not need to know mortgage-servicing terminology first. Pick the change on your statement and we will walk backward to the likely cause.

Checklist plannedThe anatomy of a payment change
A fixed-rate mortgage does not mean a fixed total payment.
Principal and interest may stay stable while escrow changes around them. That distinction is the first thing we show in every payment-change guide.
See a worked example →Principal & interest
Usually unchanged on a fixed-rate mortgage unless loan terms themselves change.
Property taxes
Assessment changes, tax-rate changes, exemptions or new-construction reassessment can move escrow.
Homeowners insurance
Premium increases can raise the amount your servicer needs to collect each month.
Escrow shortage repayment
A prior shortfall can temporarily sit on top of the new ongoing escrow amount.
Why we anchor this to Regulation XThe CFPB's current rule defines shortages and limits how servicers may collect them. We use that primary source as the baseline, then explain the math in homeowner language.

What an escrow shortage actually means — and what happens next
Understand the shortage, the ongoing escrow reset and why paying the shortage in full does not always return your payment to its old amount.
