Degree of Combined Leverage Explained for Australian Businesses (2025)

In the fast-evolving landscape of Australian business finance, understanding the degree of combined leverage (DCL) has never been more crucial. As 2025 brings new tax policies and market volatility, leveraging DCL can give your company a strategic edge—if you know how to use it.

What is the Degree of Combined Leverage?

The degree of combined leverage (DCL) is a powerful metric that quantifies how a company’s earnings per share (EPS) will respond to changes in sales. It captures the impact of both operating leverage (fixed operating costs) and financial leverage (use of debt), offering a holistic view of risk and potential return. In simple terms, DCL tells you how sensitive your bottom line is to fluctuations in revenue.

For example, if a company’s DCL is 3, a 10% rise in sales could translate to a 30% jump in EPS—amplifying both profits and potential losses.

Why DCL Matters in 2025: Policy Changes and Market Trends

Australian businesses in 2025 face a unique mix of opportunities and challenges. The Albanese government’s ongoing review of corporate tax concessions and updated thin capitalisation rules have made debt-funded expansion more complex. At the same time, post-pandemic supply chain stabilisation and robust consumer demand have injected fresh momentum into many sectors.

• Tax Reform: The 2024-25 federal budget introduced stricter deductibility caps for interest expenses, particularly affecting companies with high financial leverage.

• Interest Rate Trends: With the RBA maintaining rates at 3.6% through early 2025, the cost of debt remains stable but is closely watched.

• Sector Variability: Tech and manufacturing firms—often with high fixed costs—are experiencing greater DCL, while service-based industries generally maintain lower leverage ratios.

These shifts mean that the DCL is more than just a theoretical tool—it’s a practical way to anticipate how policy and market changes will ripple through your financials.

How to Calculate and Interpret DCL

To get your DCL, you’ll need two components:

• Degree of Operating Leverage (DOL): % Change in EBIT / % Change in Sales

• Degree of Financial Leverage (DFL): % Change in EPS / % Change in EBIT

DCL = DOL × DFL

Example: Suppose an Australian manufacturer expects a 5% increase in sales. With a DOL of 2 and a DFL of 1.5, the DCL is 3. This means EPS should rise by 15% if sales projections hold.

However, the DCL cuts both ways. In a downturn, high leverage can magnify losses. Businesses in 2025 are advised to stress-test their DCL under different revenue scenarios, factoring in rising wage costs and potential supply chain disruptions.

Real-World Applications: Using DCL in Financial Strategy

Forward-thinking CFOs are harnessing DCL to:

• Evaluate Expansion Plans: Before committing to new factories or tech investments, companies model the DCL to understand risk exposure.

• Optimise Capital Structure: With tighter tax rules on debt, many firms are recalibrating the debt-to-equity mix to achieve a balanced DCL.

• Communicate with Investors: In the ASX reporting season, clear explanations of DCL help justify earnings guidance and capital allocation decisions.

Case in Point: In early 2025, a Queensland-based agri-tech firm used DCL analysis to justify a modest increase in leverage, projecting that robust export demand would offset higher interest costs. The result: increased EPS and shareholder confidence, even as sector peers struggled with policy headwinds.

Risks and Limitations

While DCL is a valuable diagnostic tool, it’s not foolproof. Over-reliance on leverage can expose companies to severe earnings swings in volatile markets. The key is to use DCL as part of a broader risk management toolkit—alongside scenario analysis and regular financial health checks.
