Pattern 3: Business Logic Explanation

User: How is daily savings interest calculated?

Agent:
## Savings Interest Calculation Formula

### 1. Simple Interest

Interest = Principal × Annual Rate × Days / 365

**Example**:
- Principal: 100,000,000 VND
- Interest rate: 5%/year
- Term: 90 days

Interest = 100,000,000 × 5% × 90/365 = 1,232,877 VND

### 2. Compound Interest

Final Amount = Principal × (1 + Rate/n)^(n×t)

Where:
- n = number of compounding periods/year
- t = number of years

### 3. Daily Interest Calculation

Interest day i = Balance day i × Annual Rate / 365 Total Interest = Σ(Interest day i)

### 4. Sample Calculation Table

| Day | Balance | Rate | Daily Interest |
|-----|---------|------|----------------|
| 1-30 | 100M | 5% | 13,699/day |
| 31-60 | 150M | 5% | 20,548/day |
| 61-90 | 120M | 5% | 16,438/day |

**Total interest 90 days**: 1,520,548 VND
