A bank's efficiency ratio measures how much it spends to make each dollar of revenue
A bank efficiency ratio is the percentage of a bank's operating costs divided by its revenue. If a bank spends 60 cents to make a dollar, its efficiency ratio is 60%. The lower the number, the more efficiently the bank runs. A ratio below 50% is considered strong; above 70% means the bank is spending heavily relative to what it brings in.
This matters to you because inefficient banks often pass costs to customers through higher fees, lower interest rates on savings, or stricter lending standards. Banks with low efficiency ratios can afford to offer better rates and lower fees because they operate with less waste. You won't see this ratio on your statement, but it shapes the terms you're offered.
The ratio is calculated by dividing total operating expenses (salaries, technology, branch maintenance, regulatory compliance) by net revenue (interest income plus non-interest income like fees and trading gains). It's one of the few numbers that tells you whether a bank is run tightly or loosely.
Key Takeaways
- A bank's efficiency ratio shows what percentage of its revenue goes to operating costs; lower is better for customers because it often means lower fees and better rates.
- Ratios below 50% indicate a well-run bank; ratios above 70% suggest the bank may need to cut costs, which sometimes means raising fees or tightening lending.
- Large national banks often have lower ratios than small regional banks because they spread fixed costs across millions of customers.
- You can find a bank's efficiency ratio in its quarterly earnings report or on financial data sites, though most banks don't advertise it directly.
Why the ratio varies so much between banks
Large banks like JPMorgan Chase or Bank of America typically have efficiency ratios in the 55% to 65% range. They can afford this because they spread the cost of technology, compliance, and infrastructure across tens of millions of customers. A single investment in a mobile app or fraud detection system costs the same whether it serves 100,000 people or 10 million.
Small regional banks and community banks often run at 65% to 75% efficiency because they can't spread those fixed costs as wide. They may have the same regulatory burden and similar technology needs as a large bank, but fewer customers to absorb the expense. Credit unions sometimes run more efficiently because they're member-owned and don't need to generate profit for shareholders, though this isn't always the case.
Online-only banks typically have lower ratios (sometimes below 50%) because they have no physical branches. They skip the rent, utilities, and teller salaries that traditional banks carry. However, they still need servers, customer service staff, and security infrastructure, so the savings aren't unlimited.
How efficiency connects to the rates and fees you pay
A bank running at 55% efficiency has 45 cents of every revenue dollar left over for loan losses, interest paid to depositors, taxes, and profit. A bank at 75% efficiency has only 25 cents. That difference has to come from somewhere: higher deposit fees, lower savings rates, higher loan rates, or stricter lending standards.
This doesn't mean an inefficient bank is always a bad choice—sometimes a bank with higher costs offers services you need, like extensive branch networks or specialized lending. But if you're comparing two banks with similar products, the one with the lower efficiency ratio is more likely to offer better terms.
Banks also manage efficiency by changing what they do. During periods of high interest rates, banks earn more from lending, which can improve their ratio without cutting costs. During low-rate periods, they may push higher-fee products or cut staff to maintain the same ratio.
Where to find a bank's efficiency ratio
Public banks (those traded on stock exchanges) publish their efficiency ratio in quarterly earnings reports, usually in the investor relations section of their website. Search "[Bank Name] quarterly earnings" or "[Bank Name] 10-Q filing" to find the document. The ratio is often listed in a summary table or management discussion section.
Financial data sites like Yahoo Finance, Seeking Alpha, or your brokerage platform also display efficiency ratios for public banks, usually under a "Financials" or "Key Metrics" tab. Private banks and credit unions may not publish this number publicly, though some do in annual reports.
You don't need to track this number constantly, but it's useful when you're choosing between banks or wondering why one institution's rates seem consistently worse than another's.
What happens when a bank's efficiency ratio gets too high
Banks that run inefficiently for years eventually face pressure to improve. They may cut staff, close branches, invest in automation, or merge with a more efficient competitor. Sometimes a bank will sell off unprofitable divisions or exit certain markets entirely. These changes can affect you directly—branch closures, reduced service hours, or product discontinuation.
Regulators also watch efficiency ratios as a sign of operational health. A bank with a persistently high ratio may face closer scrutiny or be required to improve its systems and controls. This doesn't mean the bank is unsafe, but it signals that management needs to tighten operations.
In rare cases, a bank with a very high ratio and other problems (like high loan losses or low capital) may be forced to merge or shut down. This is why the ratio matters to depositors: it's one early warning sign that a bank is struggling.
How efficiency ratios changed during the pandemic and after
In 2020 and 2021, many banks saw their efficiency ratios improve because interest rates were low but stable, and deposit volumes surged. Banks didn't need to spend as much on marketing or lending because customers were depositing money anyway. However, this created a false picture of efficiency—the improvement came from favorable conditions, not better management.
As interest rates rose in 2022 and 2023, banks had to spend more on technology, compliance, and risk management. Some also faced deposit outflows and had to invest in customer retention. Efficiency ratios across the industry widened (got worse) during this period, even at well-managed banks.
This shows that efficiency ratios are useful for comparing banks at the same point in time, but less useful for comparing a bank to itself across different economic cycles. A bank's ratio can shift for reasons beyond management's control.
Frequently Asked Questions
Is a lower efficiency ratio always better?
Usually, yes—a lower ratio means the bank keeps more of its revenue and can pass savings to customers. However, context matters. A bank might have a low ratio because it's cutting corners on security or customer service, not because it's well-managed. Compare ratios among banks offering similar products and service levels.
What's a good efficiency ratio for a credit union?
Credit unions often run at 60% to 70% efficiency because they're smaller and member-owned. A ratio in this range is typical and healthy for a credit union. Compare your credit union's ratio to others of similar size rather than to national banks.
Can I use efficiency ratio to predict if a bank will fail?
A high efficiency ratio is one warning sign, but it's not a predictor by itself. Banks fail when they combine high costs with large loan losses, low capital, or deposit runs. A bank can have a high efficiency ratio and still be safe if it's profitable and well-capitalized. Check the FDIC's bank ratings for a fuller picture.
Do online banks always have better efficiency ratios?
Online banks often do because they skip branch costs, but not always. Some online banks spend heavily on marketing or customer acquisition, which raises their ratio. Compare specific banks rather than assuming all online banks are more efficient than all traditional banks.
Why don't banks advertise their efficiency ratio?
Banks advertise rates and features that attract customers, not operational metrics. A high efficiency ratio is not a selling point, so banks don't highlight it. Investors and analysts track the ratio, but most customers never see it. You have to look it up yourself if you want to know.
