How Bank Health Grades Work
PlainBankData assigns A-F letter grades to every FDIC-insured bank using four key financial metrics from official FDIC quarterly Call Report data.
The short answer
Each bank's grade is a 0–100 score from four FDIC metrics, capital, profitability, loan quality, and efficiency, converted to an A–F letter.
- 40%
- Tier 1 capital ratio weight
- 25%
- Return on assets weight
- 20%
- Texas Ratio weight
- 15%
- Efficiency ratio weight
A low grade does not mean your money is at risk, FDIC-insured deposits are protected to $250,000 per depositor, per ownership category, at every bank.
The Four Pillars
Our health grade combines four metrics into a 100-point score, then converts to a letter grade:
Core capital divided by risk-weighted assets. This is the most important safety metric. Regulatory minimums: 6% (adequate), 8% (well-capitalized). Exceptional banks maintain 12-20%.
Net income divided by total assets (annualized). Measures how efficiently a bank uses its assets to generate profit. Industry average: ~1%. Above 1.5% is exceptional.
Non-performing loans (NPLTOTAL) divided by tangible equity plus loan loss reserves (LNLSRES). A ratio above 100% is a serious warning sign. Below 15% is healthy.
Operating expenses divided by net revenue. Lower is better, it means the bank spends less to generate each dollar of income. Under 60% is efficient; over 80% is costly.

Data Source & Limitations
All data comes from the FDIC BankFind Suite API, which aggregates quarterly Call Report submissions from all FDIC-insured institutions. Data is for Q4 2025 (REPDTE: 20251231).
Limitations: Not all banks report all fields. Banks without Tier 1 capital data (often very large institutions with consolidated reporting) receive scores based on available metrics only. Grades are informational, not investment advice.
Frequently Asked Questions
What does a Grade A bank mean?
A Grade A bank has an excellent health score (80-100/100). It has strong capital ratios, consistent profitability, minimal problem loans, and efficient operations. These are the financial strongest banks in the country.
Is a Grade F bank dangerous?
Grade F banks have financial weaknesses, but your FDIC-insured deposits (up to $250,000) are still fully protected. A low grade means the bank may be struggling with capital, profitability, or loan quality, not that failure is imminent or certain.
What is the Texas Ratio?
The Texas Ratio was developed by Gerard Cassidy at RBC Capital Markets in the 1980s to predict bank failures. It measures non-performing assets divided by tangible equity capital plus loan loss reserves. A ratio above 100% indicates the bank has more problem loans than capital to absorb losses.
