🏦 Bank Performance Metrics: Your Bank’s Health Report Card
🌟 The Big Picture: Think of a Bank Like a Lemonade Stand!
Imagine you have the best lemonade stand in your neighborhood. You want to know:
- “Am I making good money?”
- “Am I spending wisely?”
- “Are people paying me back for lemonade they bought on credit?”
Banks ask the same questions, just with bigger numbers! Let’s learn how banks check their health using special report card metrics.
📊 Meet the 8 Magical Metrics

1️⃣ Return on Assets (ROA) 💎
What Is It?
ROA tells us: “For every dollar the bank owns, how many cents of profit did it make?”
🍋 Lemonade Stand Example
You have a stand worth $100 (table, pitcher, sign). You made $5 profit this month.
Your ROA = $5 ÷ $100 = 5% ✨
🏦 Real Bank Example
- Bank has $1 billion in assets (buildings, loans, cash)
- Bank earned $10 million profit
- ROA = $10M ÷ $1B = 1%
⭐ What’s Good?
| ROA | Rating |
|---|---|
| < 0.5% | 😟 Struggling |
| 0.5% - 1% | 😊 Okay |
| 1% - 2% | 🌟 Good |
| > 2% | 🚀 Excellent |
📝 The Formula
ROA = Net Income ÷ Total Assets × 100
Remember: Higher ROA = Bank is using its stuff smartly to make money!
2️⃣ Return on Equity (ROE) 👑
What Is It?
ROE tells us: “For every dollar the owners put in, how many cents came back as profit?”
🍋 Lemonade Stand Example
Your parents gave you $50 to start your stand. You made $10 profit.
Your ROE = $10 ÷ $50 = 20% 🎉
🏦 Real Bank Example
- Shareholders invested $100 million
- Bank earned $15 million profit
- ROE = $15M ÷ $100M = 15%
⭐ What’s Good?
| ROE | Rating |
|---|---|
| < 8% | 😟 Below average |
| 8% - 12% | 😊 Acceptable |
| 12% - 15% | 🌟 Good |
| > 15% | 🚀 Excellent |
📝 The Formula
ROE = Net Income ÷ Shareholders' Equity × 100
Key Insight: ROE shows how well the bank rewards its owners!
3️⃣ Net Interest Margin (NIM) 💵
What Is It?
NIM tells us: “How much does the bank earn from the difference between interest it charges and interest it pays?”
🍋 Lemonade Stand Example
- You borrow sugar and pay 2 cents per cup to your supplier
- You sell lemonade and charge 10 cents per cup
- Your spread = 10¢ - 2¢ = 8¢ per cup!
🏦 Real Bank Example
- Bank gives loans at 8% interest (earns money)
- Bank pays depositors only 2% interest (costs money)
- Spread = 8% - 2% = 6%
But NIM is calculated on earning assets:
- Interest earned: $80 million
- Interest paid: $30 million
- Earning assets: $1 billion
- NIM = ($80M - $30M) ÷ $1B = 5%
⭐ What’s Good?
| NIM | Rating |
|---|---|
| < 2% | 😟 Thin margin |
| 2% - 3% | 😊 Typical |
| 3% - 4% | 🌟 Strong |
| > 4% | 🚀 Very strong |
📝 The Formula
NIM = (Interest Income - Interest Expense)
÷ Average Earning Assets × 100
4️⃣ Efficiency Ratio ⚡
What Is It?
Efficiency Ratio tells us: “How many cents does the bank spend to make one dollar?”
🍋 Lemonade Stand Example
You earned $100 from selling lemonade. You spent $40 on cups, ice, and your helper.
Efficiency Ratio = $40 ÷ $100 = 40%
That means you spent 40 cents to make every dollar!
🏦 Real Bank Example
- Bank’s revenue: $500 million
- Operating expenses: $250 million
- Efficiency Ratio = $250M ÷ $500M = 50%
⭐ What’s Good?
| Efficiency Ratio | Rating |
|---|---|
| > 70% | 😟 Inefficient |
| 60% - 70% | 😊 Average |
| 50% - 60% | 🌟 Good |
| < 50% | 🚀 Excellent |
📝 The Formula
Efficiency Ratio = Operating Expenses
÷ Revenue × 100
Remember: LOWER is BETTER here! Less spending = more profit!
5️⃣ Cost-to-Income Ratio 💼
What Is It?
Very similar to Efficiency Ratio! It shows “What percentage of income goes to running the bank?”
🍋 Lemonade Stand Example
Your income from lemonade: $80 Your costs (lemons, sugar, cups): $32
Cost-to-Income = $32 ÷ $80 = 40%
🏦 Real Bank Example
- Operating income: $400 million
- Operating costs: $200 million
- Cost-to-Income = $200M ÷ $400M = 50%
💡 Quick Comparison
| Metric | What It Uses |
|---|---|
| Efficiency Ratio | Total Revenue |
| Cost-to-Income | Operating Income |
⭐ What’s Good?
| Cost-to-Income | Rating |
|---|---|
| > 65% | 😟 High costs |
| 55% - 65% | 😊 Typical |
| 45% - 55% | 🌟 Efficient |
| < 45% | 🚀 Super efficient |
Pro Tip: Banks try to keep this under 60% to stay competitive!
6️⃣ Non-Performing Loan Ratio (NPL) ⚠️
What Is It?
NPL Ratio tells us: “How many loans went bad? How many people aren’t paying back?”
🍋 Lemonade Stand Example
You let 10 friends buy lemonade “on credit” (pay later). 2 friends never paid you back! 😢
NPL Ratio = 2 ÷ 10 = 20% (Yikes!)
🏦 Real Bank Example
- Total loans given: $10 billion
- Loans not being paid back: $200 million
- NPL Ratio = $200M ÷ $10B = 2%
⭐ What’s Good?
| NPL Ratio | Rating |
|---|---|
| > 5% | 😟 Risky! |
| 3% - 5% | 😊 Watch carefully |
| 1% - 3% | 🌟 Healthy |
| < 1% | 🚀 Excellent |
📝 The Formula
NPL Ratio = Non-Performing Loans
÷ Total Loans × 100
Warning Sign: Rising NPL = More people struggling to pay back!
7️⃣ Loan-to-Deposit Ratio (LDR) 🏧
What Is It?
LDR tells us: “For every dollar people deposited, how many dollars did the bank lend out?”
🍋 Lemonade Stand Example
Friends gave you $100 to keep safe in your piggy bank. You used $80 to buy supplies for a bigger lemonade business.
LDR = $80 ÷ $100 = 80%
🏦 Real Bank Example
- Customer deposits: $5 billion
- Loans given out: $4 billion
- LDR = $4B ÷ $5B = 80%
⭐ What’s Good?
| LDR | What It Means |
|---|---|
| < 70% | 😐 Too cautious (missing opportunities) |
| 70% - 80% | 🌟 Sweet spot! |
| 80% - 90% | 😊 Aggressive but okay |
| > 90% | ⚠️ Risky (might run out of cash!) |
📝 The Formula
LDR = Total Loans ÷ Total Deposits × 100
Balance is Key: Too low = lazy money. Too high = risky!
8️⃣ Bank Profitability Analysis 📈
What Is It?
Putting it ALL together! Profitability analysis looks at ROA, ROE, NIM and more to see the complete picture of how well a bank makes money.
🎯 The Three Questions
graph TD A[Is the Bank Profitable?] --> B[ROA: Using assets well?] A --> C[ROE: Rewarding owners?] A --> D[NIM: Good interest spread?] B --> E[📊 Overall Verdict] C --> E D --> E
🏦 Real Example: Comparing Two Banks
| Metric | Bank A | Bank B | Winner |
|---|---|---|---|
| ROA | 1.5% | 0.8% | Bank A ✅ |
| ROE | 14% | 9% | Bank A ✅ |
| NIM | 3.5% | 2.8% | Bank A ✅ |
| Efficiency | 52% | 68% | Bank A ✅ |
| NPL | 1.2% | 3.5% | Bank A ✅ |
Verdict: Bank A is the clear winner! 🏆
💡 Key Insights for Analysis
- Strong profitability = High ROA + High ROE
- Sustainable profits = Healthy NIM + Low NPL
- Well-managed = Low Efficiency Ratio
- Balanced risk = Sensible LDR (70-85%)
🎯 Quick Summary: The Report Card
| Metric | What It Measures | Good Target |
|---|---|---|
| ROA | Profit from assets | > 1% |
| ROE | Profit for owners | > 12% |
| NIM | Interest spread | 3-4% |
| Efficiency | Cost control | < 60% |
| Cost-to-Income | Operating costs | < 55% |
| NPL | Bad loans | < 2% |
| LDR | Lending balance | 70-85% |
