What it is
IRR, or internal rate of return, is a time-weighted measure of performance. It expresses the annualized rate at which invested capital has grown, given the timing of every contribution and distribution. Because it reflects when cash moved, it is sensitive to how quickly capital is returned.
MOIC, or multiple on invested capital, is a simpler ratio. It compares the total value generated, realized and unrealized, with the total capital invested. It says nothing about how long that value took to arrive, which is its main limitation.
The two are complementary. IRR captures speed and timing; MOIC captures magnitude. A shorter holding period can produce a strong IRR with a modest MOIC, while a long holding period can show the reverse. Neither metric alone describes risk, liquidity or the quality of the underlying assets.
(Related terms often appear alongside them, including DPI, RVPI and TVPI, which break down realized versus unrealized value. Definitions vary by manager, so reading the reporting notes matters.)
How it’s traditionally been approached
Fund managers have traditionally reported both IRR and a multiple in quarterly and annual investor statements, particularly in private equity, private credit, real estate and other real assets. Investors then compare these figures against the fund's stated objectives and against similar strategies.
Many investors have relied on the manager's own calculations. IRR can be influenced by assumptions such as the use of subscription credit lines, the treatment of unrealized holdings and the valuation methods applied. These are legitimate practices, but they mean figures are not always directly comparable across managers.
Families and their advisors have also tended to evaluate the metrics in context: the vintage, the strategy, the stage of the fund's life and the reliability of interim valuations. Early in a fund's life, both figures can be especially provisional, because unrealized values rest on estimates rather than completed transactions.
How the right family office may help
The right MFO may help a family read these metrics as a coherent set rather than as headline numbers. That can include reconciling IRR and MOIC with distributions, remaining value and capital still to be called, so that the family sees both performance and cash-flow reality.
A visit or introductory conversation is generally exploratory. The provider may ask about your portfolio, your liquidity needs, how you currently receive reports and what decisions you are trying to make. Many families bring recent fund statements so the discussion can be concrete.
Useful questions to ask include: How do you normalize reporting across managers? How do you treat credit-line effects and unrealized valuations? How do you consolidate private holdings alongside other assets? Who is independent of the managers being evaluated? Always rely on your own licensed legal, tax and investment advisors for decisions.
The bigger picture
Performance figures can feel precise while the underlying picture remains uncertain. Not knowing whether a statement reflects strong results or merely favorable timing can create quiet worry, particularly when significant family wealth is committed to illiquid assets for many years.
Clear, consistent reporting may support steadier decision-making and calmer family conversations. Understanding what each metric does and does not say can reduce reliance on any single number, and help the people involved feel informed rather than overwhelmed.
Keep in mind
- Neither IRR nor MOIC alone describes risk, liquidity or the likelihood of future results.
- Calculation methods and valuation assumptions differ by manager, so figures may not be directly comparable.
- Unrealized values are estimates and may change before an investment is completed.
- Family offices listed on this directory are independent and responsible for their own decisions and regulatory compliance; this page is not an offer or solicitation.

What is the difference between IRR and MOIC?
IRR is an annualized measure that reflects the timing of cash flows, while MOIC is a ratio of total value to capital invested that ignores timing. IRR speaks to how quickly capital grew; MOIC speaks to how much value was created. Reading both together is generally more informative.
Which is better, IRR or MOIC?
Neither is universally better, because they answer different questions. IRR is useful for comparing investments with different time horizons, and MOIC is useful for understanding total value created. Many investors consider both alongside other measures.
Why can a fund have a high IRR but a low MOIC?
A short holding period can produce a high annualized rate even when the total multiple is modest. Early distributions and the use of credit facilities can also affect IRR. This is why the two figures should be read in context.
Does MOIC account for time?
No, MOIC does not account for how long capital was invested. Two investments with the same multiple can differ greatly in duration, which changes their economic meaning. IRR is typically used to address that gap.
How can a multi-family office help with IRR vs MOIC reporting?
A multi-family office may help consolidate and normalize private fund reporting so the metrics can be reviewed side by side. It may also help frame questions for managers about calculation methods and valuations. Final decisions remain with you and your licensed advisors.
What other metrics should be reviewed with IRR and MOIC?
Investors often review DPI, RVPI and TVPI, which separate realized from unrealized value, along with fees, liquidity terms and concentration. Definitions can vary, so it helps to confirm how each manager calculates them.
