# 🌱 I. Abstract
## 🔹 What Is Leverage?
**Leverage** is the use of fixed costs to magnify returns. In finance, it refers to how a company uses fixed operating or financing expenses to **amplify the effect of sales or earnings changes** on profitability.
It **increases potential gain — but also risk**.
### 🧮 Total Leverage = **Operating Leverage × Financial Leverage**
---
## 🔹 Types of Leverage
### 🔧 1. Degree of Operating Leverage (DOL)
**Operating leverage** arises from fixed operating costs (e.g., rent, salaries, equipment).
The higher the fixed cost base, the more profits will fluctuate with changes in sales.
#### 📐 Formula:
```
DOL = % Change in EBIT / % Change in Sales
```
#### 🔍 Interpretation:
- High DOL = High **business risk**
- If DOL = 3, a 10% increase in sales = 30% increase in EBIT
- More leverage = more earnings sensitivity
#### 🎯 Strategic Framing:
> When the business is already operating, the **fixed costs you committed to** define your operating leverage.
It’s the **opposite of using financial leverage to buy a house** — you're already in the game and amplifying outcomes from within.

### 💰 2. Degree of Financial Leverage (DFL)
**Financial leverage** comes from using debt (or other fixed-cost financing) to fund the business.
Interest payments are **financial fixed costs**.
#### 📐 Formula:
```
DFL = % Change in Net Income / % Change in EBIT
```
#### 🔍 Interpretation:
- High DFL = High **financial risk**
- Amplifies net income fluctuations
---
### 🔗 3. Degree of Total Leverage (DTL)
**Total Leverage = DOL × DFL**
#### 📐 Formula:
```
DTL = % Change in Net Income / % Change in Sales
DTL = DOL × DFL
```
#### 🔍 Why It Matters:
- Shows how sensitive **net income** is to **sales changes**
- Helps investors assess a company's **earnings volatility** and **risk structure**

# II. CFA Insight
- Covered under **Corporate Finance & Equity** topics
- Important for:
- Forecasting earnings
- Assessing operational risk
- Calculating cost of capital (WACC)
- Understanding how **fixed cost structures** amplify risk/return
> High DOL or DFL → higher **required rate of return** → higher cost of equity or debt
---
## 🧠 Economic & Strategic Application
- **Defensive business**: Low DOL + Low DFL (e.g., utilities)
- **High-growth startup**: High DOL, but may avoid DFL early
- **Real estate investing**: High DFL, low DOL (mortgage is the leverage)
> #👾/Comment Reflect on Chinese mindset often values **low financial risk** — e.g., saving cash and buying property — a form of minimizing financial leverage and exposure to ==volatility==.
