What is the Efficiency Ratio?

The Efficiency Ratio measures non-interest operating expense against net revenue (net interest income + non-interest income). It answers: how many cents of operating cost does the bank spend to generate each dollar of revenue?

Most US community banks report efficiency ratios between 55% and 70%. Below 55% is excellent. Above 75% suggests structural expense issues: possibly over-branched, over-staffed, or sub-scale relative to revenue.
