Understanding Debt Equity Ratio: Key Legal Considerations For Startup Funding Agreements

For Australian startups, funding decisions can shape everything from your runway and growth plans to who gets a say at the board table. One concept you’ll hear from lenders, investors and advisors is the debt equity ratio.

This figure does more than summarise how much you owe versus how much has been invested. It influences your control, how attractive you look to future investors, the promises you make in funding contracts, and your ongoing compliance obligations.

In this guide, we break down what the debt equity ratio means in practice, how it shows up in common Australian startup funding agreements, the legal traps to avoid, and the documents you’ll likely need. We’ll also share practical steps to find the right mix for your business goals.

Note: This guide provides general legal information for Australian startups. It isn’t financial or tax advice. It’s best to speak with your accountant or financial adviser about how a particular funding mix affects your tax position and financial reporting.

What Is The Debt Equity Ratio?

The debt equity ratio compares how much your company owes (debt) to how much shareholders have invested (equity). It’s a quick way to see how your startup is funded and how much risk is borne by creditors versus owners.

Basic formula: Debt Equity Ratio = Total Liabilities ÷ Total Equity.

For example, if you have $200,000 in loans and $400,000 in equity, your ratio is 0.5. For every $1 invested by owners, the business owes $0.50 to lenders or other creditors.

What counts as “debt” and “equity” can vary between agreements. Some contracts define debt narrowly (e.g. only interest-bearing borrowings). Others include broader liabilities (like lease liabilities or related-party loans). Equity may be defined by reference to your balance sheet (including reserves) or adjusted to exclude certain items. Always check the definitions in your contracts so you’re calculating the ratio the same way your lender or investor expects.

There’s no universal “good” ratio. A lower ratio generally signals less leverage and lower repayment pressure, which many early-stage founders prefer. Asset-heavy or later-stage startups may carry more debt comfortably. The key is matching your funding mix to your cash flow, risk appetite, growth plan and the covenants you can live with.

Why Does It Matter In Australia?

Getting your mix right is a strategic and legal decision. Here’s how the ratio can affect your startup in the Australian context:

• Investor signals: Venture and angel investors often look at leverage when assessing risk. Heavy debt can limit your ability to reinvest or weather a downturn. A sensible ratio for your industry can build confidence.
• Control vs dilution: Debt lets you avoid issuing more shares, but it usually comes with covenants and reporting obligations. Equity funding dilutes ownership but can reduce repayment pressure and expand your strategic network.
• Future rounds: Lenders and new investors will ask about your current leverage. Some loan agreements cap your ratio or require consent before new borrowings or large share issues.
• Cash flow and runway: Regular debt servicing affects your burn rate. If your revenue is seasonal or still developing, a high ratio might compress your runway faster than expected.
• Director duties and solvency: Australian directors must consider solvency when incurring debts. If leverage becomes unsustainable, you risk breaching duties and insolvent trading laws.

The bottom line: your ratio influences not just your numbers, but the contracts you sign and the legal guardrails you operate within.

How Your Ratio Shapes Funding Agreements

Most startup funding sits in one of three buckets: loans (debt), equity rounds (shares), or hybrids (like convertible notes). Your debt equity ratio can appear in each.

Loan Agreements And Covenants

When you borrow, lenders typically issue a contract that sets your repayment terms, interest, events of default and covenants. A Loan Agreement often addresses your debt equity ratio in one or more ways:

• Leverage covenant: A cap on the ratio (or a required minimum equity level). Breaching it can trigger default or a requirement to fix the breach within a set period.
• Reporting: You may need to provide periodic financial statements and a certificate confirming compliance with ratio and other covenants.
• Negative pledge / permitted debt: Restrictions on taking new debt or creating security interests without lender consent. “Permitted indebtedness” carve-outs may allow certain small or ordinary-course borrowings.
• Consent for equity issues: Some lenders require notice or consent for issuing new shares that would alter control or secondary rights.

Security is also common. Lenders may take a charge over assets and register their interest on the Personal Property Securities Register (PPSR). If you’re giving security, it’s normal to see a General Security Agreement and PPSR registrations. You can read more about why PPSR matters to businesses here: what is the PPSR?

Equity Rounds And Investor Protections

Equity funding dilutes ownership but brings in capital without scheduled repayments. Two documents tend to anchor an equity round:

• Share Subscription Agreement: Sets out the terms on which new shares are issued (price, class, warranties, conditions precedent and completion mechanics). For startups, a Share Subscription Agreement helps keep the process clear and compliant.
• Shareholders Agreement: Governs decision-making, share transfers, pre-emptive rights, drag/tag rights, investor information rights and more. A tailored Shareholders Agreement can also set expectations around future funding and how dilution will be managed.

While equity documents don’t usually impose a formal debt equity ratio, investors often negotiate information rights and negative controls (e.g. consent for taking on large debt, granting security, or issuing new shares). Your existing leverage may also influence valuation and other investor protections.

Convertible Notes And Hybrid Instruments

Convertible notes start life as debt but can convert into shares later (for example, at a qualifying equity round). They often include:

• Discounts or valuation caps on conversion.
• Events of default tied to financial covenants or non-payment.
• Consent requirements for additional debt or security while the note is outstanding.

Because they bridge debt and equity, it’s important that definitions are precise: what counts as “debt” for leverage tests while the note is outstanding, and exactly when and how conversion happens. If you’re considering a note, it’s worth using a clear, founder-friendly Convertible Note.

Security And The PPSR

Where a lender takes security, registering it on the PPSR preserves priority over those assets. This isn’t just a box-tick. Failing to register within the required time can reduce or even void your priority if the company later suffers financial distress. If security is part of your funding mix, make sure the registration and descriptions line up with the agreement and your asset position. You’ll usually see PPSR terms expressed in your security documents and loan covenants. If you need to understand the process, the PPSR is explained here: what is the PPSR?

Regulatory Notes (Without The Myths)

Issuing shares (including on conversion of notes) engages company law and may require board approvals, share issue entries in your registers, and compliance with fundraising rules. Many early-stage rounds rely on exemptions, such as those described under section 708 small-scale offerings. For a plain-English overview, see section 708.

By contrast, simply taking on a loan (or issuing a convertible note that hasn’t yet converted) doesn’t itself require an ASIC “borrowing notification.” You still need to comply with your company governance (e.g. board approvals, maintaining registers, and updating any security interests). If the note converts or you issue shares, that’s when share issue records and shareholder registers must be updated, and you may have lodgement obligations depending on what changes.

Key Legal Documents For Startup Funding

Your ideal suite depends on your funding path and timeline, but most Australian startups will rely on a mix of the following:

• Loan Agreement: Sets the repayment schedule, interest, covenants, financial reporting and events of default for any borrowed funds. Pair with board approvals and internal processes to track covenants.
• Security Documents: Where a lender takes security, expect a General Security Agreement and PPSR registrations. Make sure the security package is consistent with any existing security and intercreditor arrangements.
• Share Subscription Agreement: Used when issuing new shares, setting out pricing, warranties and conditions. It keeps your equity raise structured and compliant.
• Shareholders Agreement: Clarifies governance, voting, pre-emptive rights, and rules for future funding rounds (including consent requirements for new debt or security).
• Convertible Note: A hybrid instrument with clear conversion triggers, valuation mechanics and investor protections while the note is outstanding.
• Company Constitution: Align your constitution with your funding approach (for example, ensure it supports multiple share classes, pre-emptive rights or electronic execution processes if you plan to raise frequently).
• Cap Table / Investor Register: Up-to-date records of ownership, option pools, notes, security interests and vesting - vital for diligence and every new round.

Tip: Where security is involved, coordinate lodgements so PPSR registrations and internal minute books match your agreements. If you’ll be giving security often (for example, equipment finance), keep a checklist that includes approvals, PPSR details and covenant impact.

Practical Steps To Set A Healthy Mix

There’s no single “correct” ratio for all startups. These steps will help you find the right balance for your goals - and stay compliant along the way.

1) Map Strategy, Cash Flow And Risks

• Outline your growth plan and milestones (ship product, expand markets, hire key roles). Timing drives your cash needs.
• Model your runway under different mixes (equity-only, debt-only, hybrid). Stress test for slower revenue or higher costs.
• Think about control, governance and board composition as your cap table evolves.

2) Define The Ratio In Your Contracts

• Ensure each agreement defines “Debt” and “Equity” clearly (e.g. interest-bearing borrowings only vs. all liabilities, treatment of related-party loans, whether lease liabilities are included).
• Align covenants across agreements to avoid conflicts (for example, a lender covenant that clashes with equity investor veto rights).
• Include sensible cure periods and de minimis thresholds so minor fluctuations don’t create accidental defaults.

3) Protect Your Position When Taking Security

• Check whether existing security restricts new borrowing or additional charges. Intercreditor or priority deeds may be needed.
• Confirm the PPSR registrations reflect the correct grantor, collateral class and timing. Keep the registration details with your loan pack for quick reference.

4) Plan For Future Rounds

• Use reasonable negative controls - enough to reassure lenders and investors without blocking routine operations.
• Model cap table and leverage impacts before you sign term sheets. If you’re planning a rights issue, make sure pre-emptive rights in your Shareholders Agreement align with your timeline.
• Consider whether an early equity raise (even if smaller) reduces pressure on debt covenants and improves negotiating leverage.

5) Get Your Paperwork Right (And Keep It Current)

• Use a robust Share Subscription Agreement, a fit-for-purpose Loan Agreement, and a clear Convertible Note if you go the hybrid route.
• Where a lender takes security, expect a General Security Agreement and PPSR registration. Keep copies of PPSR verification statements with your minute book.
• Update your cap table immediately after completions and maintain board minutes approving each step.

6) Understand Regulatory Touchpoints

• Share issues (including note conversions) need to be recorded properly and may rely on fundraising exemptions such as those discussed under section 708.
• Loans and security don’t usually require an ASIC “borrowing” lodgement, but security interests should be registered on the PPSR and aligned with your contract terms.
• Tax treatment differs between debt and equity. Build a tax plan with your accountant so you understand deductibility of interest, any thin capitalisation implications and the impact of related-party loans.

7) Build In Practical Guardrails

• Set internal thresholds for taking on additional debt (for example, board consent over a nominated amount, or a maximum ratio below your covenant to allow buffer).
• Schedule periodic covenant checks - don’t wait for year end. A simple monthly dashboard can flag issues early.
• Where possible, negotiate headroom in covenants and avoid definitions that move unfavourably with accounting standard changes.

Key Takeaways

• The debt equity ratio compares what your company owes to what shareholders have invested; definitions vary by contract, so check them carefully.
• Your funding mix affects control, runway, investor perceptions and legal obligations, including covenants in loan and hybrid instruments.
• Expect leverage-related covenants, reporting and consent rights in a Loan Agreement; equity rounds will be anchored by a Share Subscription Agreement and a Shareholders Agreement.
• If security is involved, use the PPSR properly and keep documents aligned, typically through a General Security Agreement and timely registrations.
• Share issues and conversions engage company law and often rely on exemptions such as those under section 708, while simple borrowings don’t require separate ASIC “borrowing” notifications.
• Model your ratio ahead of each round, keep buffers below covenant caps, and coordinate legal, accounting and tax advice before you sign.
