Net Debt-to-EBITDA Ratio: What It Means for Australian Businesses in 2025

For Australian business owners, investors, and finance professionals, the Net Debt-to-EBITDA ratio has never been more crucial. In 2025, with shifting interest rates and evolving regulatory frameworks, understanding this metric could be the difference between strategic growth and financial missteps.

Why the Net Debt-to-EBITDA Ratio Matters in 2025

The Net Debt-to-EBITDA ratio measures a company’s ability to pay off its debts using earnings before interest, tax, depreciation, and amortisation (EBITDA). Put simply, it reveals how many years it would take to clear all net debt if EBITDA remained consistent. In Australia’s current economic landscape—marked by a cautious RBA and an uptick in corporate refinancing—this ratio is under the microscope for lenders, investors, and CFOs alike.

• Investor confidence: A lower ratio generally signals lower financial risk, attracting investors looking for stable returns.

• Lender scrutiny: Banks and alternative lenders are using stricter Net Debt-to-EBITDA thresholds in 2025, partly due to global economic headwinds.

• Boardroom strategy: Boards are leveraging this ratio to set borrowing limits and guide merger or acquisition discussions.

How the Ratio Is Calculated—and What’s Changed Recently

The formula is simple: Net Debt-to-EBITDA = (Total Debt – Cash & Equivalents) / EBITDA. But the implications are anything but basic. For example, in 2025, many ASX-listed companies are adjusting their EBITDA calculations to account for new leasing standards (AASB 16), which have shifted some off-balance-sheet liabilities into the debt figure.

Example: If an Australian logistics company has $400 million in total debt, $50 million in cash, and an EBITDA of $100 million, its Net Debt-to-EBITDA ratio is (400-50)/100 = 3.5. This would be considered moderate risk by most lenders, but in sectors like infrastructure, lenders might accept ratios as high as 6 or 7.

2025 policy update: The Australian Prudential Regulation Authority (APRA) has introduced updated guidelines that encourage banks to incorporate forward-looking stress tests on EBITDA, accounting for potential market shocks. This is nudging companies to manage their debt levels more conservatively than in previous years.

Real-World Impacts: Who’s Watching the Ratio—and Why?

Australian businesses are facing a new reality in 2025: higher refinancing costs, tighter lending standards, and increased investor activism. Here’s how the Net Debt-to-EBITDA ratio is shaping decisions:

• SMEs and private companies are finding that lenders often set hard caps on this ratio—sometimes as low as 2.5 for unsecured finance.

• Large corporates are being pushed to disclose Net Debt-to-EBITDA in annual reports and analyst briefings, especially if gearing is high or debt-funded expansion is on the horizon.

• Investors are using the ratio to screen for companies that are vulnerable to rising interest rates or revenue shocks.

Case in point: In early 2025, a major Australian retailer’s attempt to raise $300 million in new debt was delayed when its Net Debt-to-EBITDA ratio breached the 4.0 threshold set by its banking syndicate. The company was forced to divest non-core assets to bring the ratio back in line and regain lender confidence.

Best Practices for Managing Your Net Debt-to-EBITDA Ratio

With economic uncertainty and regulatory shifts in play, here are some tips for keeping this metric in check:

• Regular monitoring: Integrate ratio tracking into your monthly financial reporting, not just annual reviews.

• Scenario planning: Run EBITDA sensitivity analyses to see how downturns or margin squeezes could affect your ratio.

• Proactive communication: If you anticipate a spike in the ratio (e.g., from a major acquisition), engage with lenders and investors early to explain your strategy.

• Debt structure optimisation: Consider refinancing or restructuring debt to smooth out maturities and reduce short-term pressure on the ratio.
