When evaluating an Alternative Investment Fund (AIF), investors often focus on one question: how much return can the investment generate? However, understanding AIF returns requires more than looking at a single percentage.
Alternative investment funds may call capital in stages, invest it over time and distribute proceeds at different points during the fund’s life. As a result, two funds can report similar total returns but deliver very different investment experiences.
This is why AIF returns comparison should consider multiple performance metrics, particularly the Internal Rate of Return (IRR), Extended Internal Rate of Return (XIRR) and Multiple of Invested Capital (MOIC).
Each metric explains a different aspect of performance. IRR and XIRR consider the timing of cash flows, while MOIC shows how the total value compares with the capital invested. Understanding all three can help investors ask better questions when reviewing an AIF’s performance.
Why Are Different AIF Return Metrics Important?
AIFs can invest in private equity, private credit, real estate and other alternative investment strategies. These investments may have different holding periods, cash-flow patterns, fee structures and risk profiles.
For example, one fund may distribute money to investors relatively early, while another may retain capital for several years before returning it. Comparing their total gains alone may not provide a complete picture.
Three commonly used metrics help investors examine performance from different angles:
- IRR: Estimates the annualised rate of return based on the amount and timing of cash flows.
- XIRR: Calculates an annualised return using the actual dates of cash flows.
- MOIC: Measures the total investment value relative to the capital invested.
No single metric tells the whole story. Investors should consider these measures alongside fees, realised gains, unrealised valuations, investment risks and the fund’s remaining life. The CFA Institute also explains that IRR is commonly used for alternative investments, while MOIC does not account for the timing of cash flows.
1. What Is IRR in AIF Investing?
Internal Rate of Return, or IRR, is an annualised return metric that considers the timing and amount of investment cash flows.
In simple terms, IRR estimates the annual rate at which an investment’s inflows and outflows balance mathematically. It is particularly useful when an investment involves multiple contributions and distributions over time.
How Does IRR Work?
Suppose an investor commits capital to an AIF. The fund calls that capital over time, deploys it into investments and eventually distributes proceeds as investments generate cash or are exited.
IRR considers the timing of these cash flows rather than simply comparing the initial investment with the final amount received.
For example, receiving ₹15 lakh after investing ₹10 lakh over a relatively short period is not equivalent to receiving the same amount after a much longer period. The total gain is the same, but the annualised return differs.
What Should Investors Know About IRR?
IRR can be useful when comparing investments with different cash-flow patterns. However, it has limitations.
- It depends on the timing of capital contributions and distributions.
- Early distributions can influence the reported IRR significantly.
- Interim valuations may affect calculations when an investment has not been fully realised.
- It does not independently show the total amount of profit generated.
- It should be assessed alongside the investment’s risks and fees.
A reported IRR should therefore be examined together with the underlying cash-flow history and the assumptions used in calculating it.
2. What Is XIRR and How Is It Different from IRR?
Extended Internal Rate of Return, or XIRR, is used to calculate annualised returns when cash flows occur on specific, potentially irregular dates.
This is particularly relevant when an investor contributes capital in multiple instalments or receives distributions at different times.
How Does XIRR Work?
Consider an investor who contributes ₹5 lakh in January, another ₹5 lakh in September and receives a distribution the following year.
Because these transactions occur on different dates, calculating the return using actual dates can provide a more suitable annualised measure.
In spreadsheet software such as Microsoft Excel, the XIRR function calculates the return using a series of cash flows and their corresponding dates.
IRR vs XIRR: What Is the Difference?
| Feature | IRR | XIRR |
|---|---|---|
| Cash-flow timing | Generally assumes regular intervals between periods | Uses actual transaction dates |
| Best suited for | Cash flows occurring at regular intervals | Cash flows occurring on irregular dates |
| Common use | Periodic investment models | Investments with staggered contributions and distributions |
| Output | Annualised rate under the assumed period structure | Annualised rate based on actual dates |
| Key consideration | Period assumptions must be appropriate | Cash-flow dates and signs must be entered correctly |
For private-market investments, XIRR is often useful because capital calls and distributions may not follow a regular monthly or annual schedule.
However, the calculation method should always be checked before comparing two reported figures. Investors should confirm that the same types of cash flows and comparable performance periods are being used.
3. What Is MOIC in Private Market Investments?
Multiple of Invested Capital, or MOIC, measures the total value of an investment relative to the capital invested.
Unlike IRR and XIRR, MOIC does not measure an annualised rate of return. Instead, it indicates how many times the invested capital is represented by the total value.
A common calculation is:
MOIC = Total Investment Value ÷ Invested Capital
Depending on the reporting convention, total investment value may include distributions already received and the remaining value of investments that have not yet been realised.
Example of MOIC
Suppose an investment has the following figures:
- Capital invested: ₹10 lakh
- Distributions received: ₹4 lakh
- Remaining investment value: ₹11 lakh
- Total value: ₹15 lakh
The MOIC calculation is:
MOIC = ₹15 lakh ÷ ₹10 lakh = 1.5x
This means the investment’s total value is 1.5 times the capital invested, including both distributions received and the remaining investment value.
However, the ₹15 lakh total value includes ₹11 lakh of remaining investment value. That amount may not yet have been realised or distributed to the investor.
If the remaining investment value later changes, the reported MOIC can also change.
What Does MOIC Tell Investors?
MOIC helps investors understand the scale of value generated relative to capital invested.
For example, a 1.5x MOIC means the total value is 1.5 times the invested capital. It does not, by itself, indicate whether the investment generated that value over two years or ten years.
This is an important distinction. MOIC should generally be read alongside IRR or XIRR to understand both the total value and the timing of returns.
IRR vs XIRR vs MOIC: A Quick Comparison
| Metric | What It Measures | Considers Cash-Flow Timing? | Annualised? |
|---|---|---|---|
| IRR | Annualised rate of return | Yes | Yes |
| XIRR | Annualised rate using actual cash-flow dates | Yes, using actual dates | Yes |
| MOIC | Total investment value relative to capital invested | No | No |
Each metric answers a different question.
- IRR asks: What annualised return is implied by the cash flows?
- XIRR asks: What annualised return results when the actual dates are considered?
- MOIC asks: How many times the invested capital is represented by the total value?
For a more complete AIF returns comparison, investors should examine these metrics together instead of selecting a fund based on one headline number.
Gross Returns vs Net Returns: Why the Difference Matters
Another important consideration is whether the reported return is gross or net.
Gross returns generally represent investment performance before specified fund-level fees and expenses. The exact definition can vary depending on the fund’s reporting methodology.
Net returns generally reflect performance after the applicable fees and expenses included in the calculation. For an investor, the relevant net figure depends on the specific fund terms, fee arrangements and reporting basis.
This distinction is especially important when comparing alternative investment funds. For a broader comparison of fixed-income options, read our guide on Private Credit vs Bonds.
For example, two funds may report similar gross performance but deliver different net outcomes because their management fees, performance fees and expenses differ.
Investors should also check whether a reported metric represents the underlying investment portfolio, an underlying fund, or the return experienced by the investor in the AIF.
How Do These Metrics Apply to a Private Credit Fund of Funds?
A private credit Fund of Funds (FoF) invests in underlying private credit funds rather than directly lending to borrower companies through the FoF structure.
This creates multiple levels of performance that investors should distinguish.
Understanding the Two Levels of Performance
Level 1: Underlying private credit funds
The underlying funds may provide financing to companies and earn income or other proceeds under their investment agreements. Their reported performance can be assessed using metrics such as IRR, XIRR and MOIC, depending on the fund’s reporting approach.
Level 2: The Fund of Funds
The FoF invests in and monitors a portfolio of underlying funds. Its own performance reflects the cash flows and value of its investments, together with the applicable fees, expenses and other factors at the FoF level.
To understand this process in more detail, read our guide on how private credit Fund of Funds generate returns.
Therefore, an underlying fund’s return should not automatically be treated as the FoF investor’s return.
Why Look-Through Analysis Matters
When evaluating a private credit FoF, investors should consider:
- The performance history of the underlying funds.
- Whether the reported figures are gross or net, and what costs they include.
- The timing of capital calls and distributions.
- The proportion of returns that has been realised versus the portion based on remaining investment valuations.
- The FoF’s own fees, expenses and cash flows.
- The risks and concentration of the underlying portfolio.
This approach provides a more complete understanding of how underlying-fund performance relates to the investment experience at the FoF level.
5 Questions to Ask Before Comparing AIF Returns
Before comparing two AIFs, investors can use the following checklist.
1. Are the Returns Gross or Net?
Confirm whether fees and expenses have been deducted and which costs are included in the reported figure.
2. Are the Investment Periods Comparable?
A fund that has been investing for several years may not be directly comparable with a recently launched fund. Consider the fund’s vintage, deployment stage and cash-flow history.
3. How Much of the Performance Is Realised?
Distinguish proceeds already received from the value assigned to investments that remain in the portfolio.
4. Are the Cash Flows and Dates Available?
Where possible, examine the timing of capital contributions and distributions to understand how IRR or XIRR has been calculated.
5. What Risks Could Affect Future Performance?
Past metrics do not eliminate investment risk. Consider the strategy, concentration, credit quality, liquidity, valuation methodology and other factors relevant to the fund.
Common Mistakes to Avoid When Comparing AIF Returns
Investors should be careful not to:
- Compare IRR and MOIC as if they measure the same thing.
- Assume that a higher IRR always means a higher total profit.
- Ignore fees when comparing gross and net returns.
- Treat unrealised valuations as cash already received.
- Compare funds without considering their investment periods and strategies.
- Assume that historical performance guarantees future returns.
These checks help investors interpret performance figures more carefully and ask more informed questions during due diligence.
Conclusion
IRR, XIRR and MOIC are useful metrics for understanding alternative investment performance, but each measures something different. IRR estimates an annualised return, XIRR incorporates actual cash-flow dates, and MOIC measures total value relative to invested capital.
For an effective AIF returns comparison, investors should consider all three alongside gross and net performance, fees, realised and unrealised value, investment duration and risk.
For a private credit Fund of Funds, it is also essential to distinguish the performance of underlying private credit funds from the performance of the FoF itself. Understanding these differences can help investors evaluate reported returns more thoughtfully.
Frequently Asked Questions (FAQs)
1. What is the difference between IRR and MOIC?
IRR measures the annualised rate of return based on cash flows and their timing. MOIC measures total investment value relative to capital invested without accounting for the time taken to generate that value.
2. Why is XIRR useful for AIF investments?
XIRR uses actual cash-flow dates. This can be useful when capital contributions and distributions occur at irregular intervals, as they often can in alternative investments.
3. Can an AIF have a high MOIC but a lower IRR?
Yes. An investment can generate a high total multiple over a long period but have a lower annualised return than an investment that generates a smaller multiple more quickly.
4. Should investors compare gross IRR or net IRR?
Both can provide useful information, but they answer different questions. Gross IRR helps assess performance before specified costs, while net IRR is more relevant to investor-level outcomes when the applicable fees and expenses have been deducted. Always check the calculation methodology.
5. Does a higher IRR guarantee a better investment?
No. IRR does not capture every aspect of investment performance. Investors should also consider total value, risk, fees, cash-flow timing, liquidity and whether reported gains have been realised.
6. Is an underlying private credit fund’s IRR the same as a Fund of Funds investor’s return?
No. The FoF invests in underlying funds, and its own performance reflects the cash flows and value of those investments, together with applicable FoF-level fees, expenses and other factors. The two return figures can therefore differ.
7. Do past AIF returns guarantee future performance?
No. Past performance is not a guarantee of future results. Investment outcomes depend on the strategy, underlying assets, market conditions, costs and other risks.
