## Range and Interpretation of DOL, DFL, and DCL
### Degree of Operating Leverage (DOL)
DOL measures the sensitivity of EBIT to changes in Sales.
Formula:
```
DOL = % Change in EBIT / % Change in Sales
= Contribution / EBIT
```
| Situation | DOL Value |
|---|---|
| Zero Sales | DOL = 0 |
| At BEP (EBIT = 0) | DOL → ∞ |
| Sales > BEP | DOL > 1 (Positive) |
| Sales < BEP (loss zone) | DOL is Negative |
> Interpretation: Higher DOL = Greater sensitivity of EBIT to sales changes = Higher Business Risk.
### Degree of Financial Leverage (DFL)
DFL measures the sensitivity of EPS to changes in EBIT.
Formula:
```
DFL = % Change in EPS / % Change in EBIT
= EBIT / (EBIT - Interest - Pref Dividend/(1-t))
```
| Situation | DFL Value |
|---|---|
| No fixed financial charges | DFL = 1 |
| EBIT = Interest (Financial BEP) | DFL → ∞ |
| EBIT > Interest | DFL > 1 (Positive) |
| EBIT < Interest | DFL < 0 (Negative) |
| Between 0 and 1 | Never possible |
> Critical Rule: DFL can never be between 0 and 1. It is either ≥ 1 or ≤ 0.
### Degree of Combined Leverage (DCL)
DCL captures the total risk — sensitivity of EPS to Sales.
Formula:
```
DCL = DOL × DFL
= % Change in EPS / % Change in Sales
= Contribution / (EBIT - Interest - Pref Dividend/(1-t))
```
| Situation | DCL Value |
|---|---|
| No fixed operating or financial costs | DCL = 1 |
| Sales = BEP or EBIT = Interest | DCL → ∞ |
| Sales > BEP and EBIT > Interest | DCL > 1 (Positive) |
| Sales < BEP or EBIT < Interest | DCL is Negative |
### Financial Leverage Analysis — Four Key Situations
| Situation | Result |
|---|---|
| No Fixed Financial Cost | No Financial Leverage (DFL = 1) |
| Higher Fixed Financial Cost | Higher Financial Leverage |
| EBIT > Financial Break-even | Positive Financial Leverage |
| EBIT < Financial Break-even | Negative Financial Leverage |
### Financial Break-Even Point
The EBIT level at which EPS = 0.
```
Financial BEP = Interest + [Preference Dividend / (1 − Tax Rate)]
```
