Why Did My Payment Change?

It depends on your jurisdiction. Many areas apply a millage/tax rate to an assessed or taxable value that may differ from market value or purchase price, and can include separate county, municipal, school and special-district levies plus exemptions or credits. This calculator lets you enter a known effective rate or assessed value rather than assuming home value × a single rate is always correct — verify jurisdiction-specific rules with your local assessor.

Your base monthly escrow is your annual property tax plus annual homeowners insurance (plus any other escrowed items like flood insurance), divided by 12. Your servicer may also require a cushion/reserve on top of that — see the Escrow Requirement section below.

Principal and interest stay fixed on a fixed-rate loan, but the escrow portion of your payment can change independently — usually because property taxes or insurance premiums went up, or because your servicer found an escrow shortage during its annual analysis and is spreading the shortfall across your next 12 payments.

A shortage happens when your escrow account's actual or projected balance is less than what's required to cover upcoming tax and insurance bills — often because taxes or insurance rose during the year. Your servicer generally lets you pay it in a lump sum or spread it over the next escrow year (commonly 12 months, but confirm your servicer's specific terms).

It depends on your cash position and priorities. Paying upfront avoids the temporary monthly increase but requires cash now; spreading it keeps more cash on hand but raises your monthly payment for the repayment period. Neither is universally better — compare both in the Escrow Shortage section below.

Only partly, if taxes or insurance permanently increased. Your payment drops by the shortage-repayment amount once that's paid off, but it settles at the new, higher base escrow — not your old payment. See the Current / Temporary / Stabilized Payment section for your specific numbers.

Many jurisdictions initially record taxes based on land value or a partially completed home, not the finished property. Once the county reassesses the completed home — sometimes months after closing — taxes commonly increase substantially. Use the New Construction Tax Shock section below to model this.

Timing varies by jurisdiction and can take anywhere from several months to over a year after closing, depending on local reassessment cycles. Ask the builder or local assessor for the specific timeline in your area — this calculator models the dollar impact, not the exact date.

Use the tax scenario percentages (or your own custom figure) above to see the exact monthly and annual impact on your escrow and total payment, based on the numbers you enter.

These are educational estimates based on the numbers you enter. Actual assessed values, tax rates, exemptions, insurance premiums, escrow cushion requirements and shortage repayment terms vary by jurisdiction, insurer, loan type and servicer. Always verify with your local assessor, insurer, and your servicer's official escrow analysis.
