Bank Behavior Benchmarks:

6 Months Inactive: Card marked dormant; risk models flag for potential credit line decrease (CLD).
12–18 Months Inactive: High risk of silent issuer cancellation (especially store cards and tier-2 banks).
24+ Months Inactive: Almost universal automatic closure across major US issuers (Chase, Amex, Citi, Capital One).

Credit Bureau Mechanics: Inactivity Myths vs Reality

The All-Zero (AZ) Penalty

Reporting $0 balances across 100% of revolving accounts triggers a known 12–20 point FICO scoring suppression because the algorithm treats total non-use as lack of recent credit management data. The optimal strategy is AZEO (All Zero Except One), keeping 1 card reporting 1–5% utilization.

The AAoA Time Bomb

When an issuer closes an idle account in good standing, it continues to age on your FICO report for up to 10 years. However, VantageScore drops closed accounts much sooner, and once that 10-year window expires, your Average Age of Accounts contracts drastically.

The Automated Keep-Alive Fix

You never need to carry a balance or pay a penny in interest. Setting up an automated $1.99 micro-charge (e.g. Amazon balance reload, iCloud, or Spotify) with Auto-Pay in full keeps credit limits intact indefinitely and reports continuous on-time payments.
