Efficiency Ratio
Also known as Efficiency
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?
Formula
Non-Interest Expense is the bank's operating cost: salaries, premises, technology, professional services, FDIC assessments. Net Interest Income + Non-Interest Income is total operating revenue. The lower the ratio, the more efficient the bank.
Why it matters
Efficiency Ratio is the operating-leverage metric. A bank with 55% efficiency converts 45 cents of every revenue dollar into pre-tax operating income. Banks with strong technology investments, scale advantages, or focused product sets typically run lower ratios.
How to interpret
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.
Thresholds
| Range | Label | Interpretation |
|---|---|---|
| < 55% | Strong | Top-quartile efficiency. |
| 55–65% | Normal | Typical for healthy community banks. |
| 65–75% | Watch | Above-peer expense burden. |
| > 75% | Concern | Structural efficiency problems. |
Worked example
Frequently asked
Is a lower efficiency ratio always better?
Mostly yes — but a very low ratio (below 45%) can sometimes reflect under-investment in growth (sales staff, technology, branches) that will hurt longer-term competitive position. The trend matters more than the absolute number in isolation.
How does technology investment show up in efficiency?
Short term, it raises expense (more tech costs). Long term, if the technology delivers automation or productivity gains, revenue grows faster than expense and the ratio improves. The trend over 2-3 years tells the story.
