When you invest through a managed fund or alternative investment in Australia, it’s important to know how fees are charged—especially performance fees. One of the most significant mechanisms that can affect your returns is the high-water mark. In 2026, as more Australians look to diversify their portfolios, understanding the high-water mark can help you make informed decisions and avoid unnecessary costs.

The high-water mark is designed to ensure that fund managers only receive performance fees when your investment reaches new profit highs, not simply when it recovers from previous losses. This approach aims to align the interests of investors and managers, so you’re not paying twice for the same performance.

What Is a High-Water Mark?

A high-water mark is a reference point used by investment managers to determine when performance fees are payable. If your investment reaches a new peak value, that amount becomes the high-water mark. The manager can only charge a performance fee on profits above this level. If your investment falls below the high-water mark and later recovers, no performance fee is charged until your balance surpasses the previous peak.

Example:

  • If your investment grows to $100,000, then drops to $90,000, and later returns to $100,000, the manager cannot charge a performance fee until your balance exceeds $100,000.

This system helps protect investors from being charged performance fees on gains that simply recover earlier losses, rather than on new profits.

How High-Water Marks Work in Practice

In Australia, high-water marks are commonly used in managed funds, hedge funds, and other alternative investments that charge performance-based fees. The structure is intended to ensure fairness and transparency for investors.

Performance Fee Calculation

Performance fees are typically calculated as a percentage of the profits above the high-water mark. For example, if a fund charges a 20% performance fee and your investment grows from a previous high of $120,000 to $130,000, the manager would be entitled to 20% of the $10,000 gain, or $2,000.

If your investment drops below the high-water mark—say, to $110,000—the high-water mark remains at $120,000. No performance fee is charged on gains until your investment exceeds $120,000 again.

Disclosure and Transparency in 2026

Australian regulators require fund managers to clearly disclose how high-water marks and performance fees are calculated. Product Disclosure Statements (PDS) must include worked examples, so investors can understand how fees might apply in different scenarios. This transparency helps you compare different funds and assess whether their fee structures are suitable for your needs.

Key Features and Variations to Watch For

While the high-water mark is designed to protect investors, the details can vary between funds. Here are some important features and potential pitfalls to be aware of in 2026:

Reset Clauses

Some funds include reset provisions, which can lower the high-water mark after periods of underperformance or at set intervals. This means a manager could start earning performance fees again sooner, even if the fund hasn’t fully recovered from past losses. It’s important to check whether a fund uses reset clauses and understand how they might affect your fees over time.

Crystallisation Frequency

The frequency at which performance fees are calculated and paid—known as crystallisation—can also impact your costs. Some funds crystallise fees monthly, quarterly, or annually. More frequent crystallisation can sometimes result in higher fees, especially in volatile markets where your investment value fluctuates.

Tax Implications

Performance fees, including those calculated with a high-water mark, can affect your after-tax returns. The way fees are structured may influence your taxable income or capital gains. As tax rules can change and may be subject to ongoing debate, it’s wise to consider how fees interact with your broader tax situation and seek professional advice if needed.

Practical Example: How a High-Water Mark Works

Let’s look at a simplified example to illustrate how a high-water mark operates in practice:

  • Year 1: You invest $50,000 in a managed fund with a 15% performance fee above the high-water mark. Your portfolio grows to $60,000. The performance fee is 15% of the $10,000 gain, or $1,500.
  • Year 2: The market declines and your balance drops to $52,000. No performance fee is charged, as your investment is below the previous high-water mark.
  • Year 3: The portfolio rebounds to $62,000. The new gain above the previous high-water mark ($60,000) is $2,000, so the performance fee is 15% of $2,000, or $300.

This structure ensures you only pay performance fees on new profits, not on gains that simply recover earlier losses.

What Should Investors Ask?

Before investing in a fund that charges performance fees, consider asking the following questions:

  • How is the high-water mark calculated and maintained?
  • Are there any reset clauses or provisions that could lower the high-water mark?
  • How often are performance fees crystallised?
  • How do performance fees affect my after-tax returns?
  • Can you provide a worked example of how fees would apply to my investment?

Understanding these details can help you compare different funds and choose one that aligns with your investment goals and risk tolerance.

Why the High-Water Mark Matters in 2026

As managed funds and alternative investments continue to grow in popularity among Australians, the high-water mark remains a key tool for aligning fund manager incentives with investor outcomes. It helps ensure that you only pay for genuine outperformance, not for a recovery from previous downturns.

However, not all high-water mark structures are the same. By reviewing the specific terms of each fund and asking the right questions, you can make more informed decisions and better protect your investment returns.

Conclusion

In 2026, understanding the high-water mark is essential for any Australian investor considering managed funds or alternative investments with performance-based fees. This mechanism plays a crucial role in ensuring fairness and transparency, helping you avoid excessive charges and align your interests with those of your fund manager. Always review the details of how the high-water mark is applied in any fund you consider, and don’t hesitate to ask for clear explanations before committing your capital.
