Net Charge-Off Ratio
Also known as NCO
The Net Charge-Off ratio (annualized) measures loans actually written off as uncollectible (less subsequent recoveries) divided by average loans outstanding. It is the realized credit loss experience of the bank.
Formula
Charge-offs occur when the bank determines a loan is uncollectible. Recoveries are amounts collected on previously charged-off loans. The metric is typically reported quarterly and annualized by multiplying by 4 (or by computing the rolling-four-quarter sum).
Why it matters
NCO is the realized loss number — what actually happened, vs NPL and NPA which are leading indicators. It is the input to the loan loss reserve methodology and the trailing credit-quality benchmark. Sustained NCO above the bank's ACL/Loans ratio means the reserve is being consumed faster than rebuilt.
How to interpret
Most US community banks report annualized NCO between 0.1% and 0.5%. Consumer-heavy or credit-card-issuing banks can report 2-5% as a normal range (different risk model). Compare to historical trend — NCO spikes typically precede recessions by 1-2 quarters.
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| < 0.25% | Strong | Very low realized losses. |
| 0.25–0.75% | Normal | Typical commercial bank range. |
| 0.75–1.5% | Watch | Elevated realized losses. |
| > 1.5% | Concern | Significant credit losses. |
Worked example
Frequently asked
Why annualize?
Quarterly charge-offs are noisy and can be skewed by one large loan. Annualizing (or using rolling-four-quarter sums) smooths out the noise and produces a comparable rate.
Are charge-offs the same as losses?
Approximately. A charge-off is the accounting recognition that the loan is uncollectible. Recoveries (which net against charge-offs) are amounts the bank later collects on charged-off loans — the net of the two is the realized credit loss.
