AZEO (All Zero Except One)
Also known as: All zero except one
A pre-application FICO tactic: pay every credit card to a $0 reported balance by its statement closing date except one, which reports a small balance. FICO publishes no point value for the effect.

AZEO leans on what FICO says about the "amounts owed" category: the model looks at how many accounts carry balances and at how much of the available credit is in use. The models look both at aggregate utilization (total balances divided by total limits) and per-card utilization (each card's balance divided by its own limit). A consumer who carries balances on multiple cards is generating signal on every account; AZEO concentrates that signal onto a single account, with all other accounts reporting at zero. FICO appears to score this configuration slightly better than the same aggregate utilization spread across multiple cards.
The mechanics are timing-sensitive. Credit card issuers typically report your account balance to the bureaus once per month, on or shortly after the statement closing date. The figure they report is the statement balance — what your balance was on that closing date — not your balance at any other point in the cycle. To execute AZEO, you pay each card's balance down to zero before its statement closes, except one card on which you let a small balance (forum convention is a balance in the low single digits as a percentage of that card's limit) report. Within a billing cycle or two, the bureaus reflect the new utilization configuration, and your FICO updates accordingly.
Any score gain from AZEO is temporary. Once the reporting cycle changes and balances return to their normal pattern, the score reverts. The tactic is most useful before a major credit application — applying for a mortgage, an auto loan, or a high-end credit card — where the marginal FICO points can move you across a tier boundary (Fannie Mae's mortgage pricing grid moves in 20-point bands such as 740-759 and 760-779) that affects the rate offered or the approval decision. It is less useful as a standing strategy, because the manual coordination required to maintain AZEO month after month is high and the long-term score effect of slightly higher utilization is small at the levels most readers run.
The evidence for AZEO is self-reported: forum users comparing their own scores before and after, with results that vary widely by profile, and FICO has never published a point value for it. It does not eliminate the need for the underlying credit fundamentals — payment history, length of credit history, available credit, account mix — and it cannot rescue a score damaged by recent missed payments or high overall debt. But for a reader 30–60 days from a consequential application, AZEO is a low-cost lever worth trying. Whether to use it depends on whether you have a specific application in mind and how close you are to a scoring threshold.

- How your FICO score is calculated: the five weighted factors The five factors behind your FICO score — payment history, amounts owed, length, mix, new credit — with the official weights and a worked example.
- CFPB's 30% credit utilization rule: real, but the cliff is a myth Verified against the official sources: the CFPB does tell consumers to stay below 30% — and myFICO says lower is better, no penalty at 31%. Best band: 1–9%.
- Credit utilization The ratio of revolving credit balances to revolving credit limits, expressed as a percentage. Both aggregate utilization (across all cards) and per-card utilization matter. The second-largest FICO factor (30%) and the lever most readily adjustable in 30–60 days.
- FICO Score The 300–850 credit score produced by the Fair Isaac Corporation's scoring models. The score model used by the majority of US lenders for consumer credit underwriting. Calculated from bureau data on payment history, amounts owed, length of credit history, credit mix, and new credit.
