IRR and MOIC measure different things, and comparing two deals on only one of them can make a mediocre investment look great or a strong one look weak. Internal rate of return (IRR) captures how fast an investment returns capital, annualized as a percentage. Multiple on invested capital (MOIC) captures how much money came back relative to what went in, with no reference to how long it took. A deal sponsor who reports only one number is telling half the story.
This guide walks through how each metric is calculated, why they can point in opposite directions on the same deal, and how to read both together when comparing SPVs or evaluating a single exit.

What IRR measures
IRR is the annualized rate of return that makes the net present value of all cash flows, in and out, equal to zero. It accounts for the timing of every capital call and every distribution, which is what makes it useful for comparing deals that returned capital on different schedules. A deal that returns 2x in one year has a far higher IRR than a deal that returns the same 2x over seven years, even though an investor ends up with the same multiple on their money in both cases.
IRR gets harder to interpret with irregular cash flows, several rounds of follow-on capital, or a long holding period with no interim distributions. Small changes in the assumed timing of a single cash flow can move IRR meaningfully, which is why sponsors often report it alongside, rather than instead of, MOIC.
What MOIC measures
MOIC is the total value returned to an investor divided by the total capital they invested. A $100,000 investment that returns $350,000 produced a 3.5x MOIC. It ignores time entirely: a 3.5x return over two years and a 3.5x return over nine years show the identical MOIC, even though almost every investor would prefer the faster version.
MOIC is simple to calculate and easy to explain to a limited partner who wants a single, intuitive number for how a deal performed. Its weakness is close to its strength: because it drops the time dimension, it says nothing about capital efficiency or how quickly an investor can redeploy the money that came back.
Why the two metrics can disagree
A deal that exits quickly at a modest multiple can post a very high IRR and an unremarkable MOIC. A deal that takes a decade to return a large multiple can post a strong MOIC and an unremarkable IRR. Neither result is wrong; they are measuring different things, and a fund manager who wants to show the best possible number for a given deal can usually find one metric that flatters it more than the other.
A worked example
For example, suppose two SPVs each raise $1,000,000 and each return $3,000,000 to investors at exit, a 3x MOIC in both cases.
| SPV A | SPV B | |
|---|---|---|
| Capital invested | $1,000,000 | $1,000,000 |
| Amount returned | $3,000,000 | $3,000,000 |
| MOIC | 3.0x | 3.0x |
| Holding period | 2 years | 8 years |
| Approximate IRR | 73 percent | 15 percent |
Both SPVs delivered the same multiple, but SPV A returned that multiple four times faster, so its capital could be redeployed into a new deal years before SPV B’s capital came back. An investor comparing only MOIC would miss that difference entirely.
When each metric matters more
MOIC tends to matter more to an investor thinking in absolute dollars: how much did a specific check turn into, regardless of how long it took. IRR tends to matter more to an investor managing a portfolio of deals who cares about how quickly capital comes back so it can be reinvested, since a high IRR compounds across a series of deals in a way a high MOIC on a single slow deal does not.
Institutional limited partners typically ask for both, along with DPI and TVPI, since a single metric rarely tells the full story of how a fund or SPV performed. For a deeper look at those companion metrics, see The Definitive Guide to Venture Capital Valuation Methods.
Common ways the numbers get distorted
- Reporting IRR on unrealized positions using a generous mark rather than a conservative one, which inflates IRR before any cash has actually returned.
- Comparing MOIC across deals with very different holding periods without mentioning the time difference at all.
- Excluding fees and carried interest from either calculation, which shows gross rather than net performance to the limited partner.
- Blending several unrelated deals into one IRR figure, which can hide a single bad outcome inside an otherwise strong number.
A limited partner reviewing a track record should ask whether a reported IRR is realized, based on actual cash returned, or partly projected based on the sponsor’s own valuation of positions still held.
Reading both metrics together
Neither IRR nor MOIC on its own answers the question a limited partner actually cares about, which is whether the deal was a good use of their capital compared with the alternatives available at the time. A high MOIC with a long holding period and a high IRR with a small check size can both be true statements about the same portfolio without either one being the whole picture. Reporting both, with the holding period stated plainly, gives an investor what they need to judge a deal on its own terms.
A track record built from a handful of deals benefits from showing IRR and MOIC deal by deal rather than only as a blended average across the whole portfolio. An average can hide a single outsized winner sitting alongside several deals that returned less than the capital put into them, and a limited partner deciding whether to back the next SPV usually wants to see that spread rather than one smoothed-over number.
Frequently asked questions
Is a higher IRR always better than a higher MOIC?
Not necessarily. A short, fast deal can post an excellent IRR on a small absolute gain, while a longer deal with a lower IRR can still return far more total capital. Which matters more depends on what the investor plans to do with the capital once it returns.
How is IRR calculated for an SPV with multiple capital calls?
Each capital call and each distribution is treated as its own cash flow on its own date, and IRR is the discount rate that sets the net present value of that full series of cash flows to zero.
Can MOIC be below 1.0x?
Yes. A MOIC below 1.0x means the investment returned less than was invested, regardless of how the loss is distributed across the holding period.
Why do sponsors sometimes report only one of the two metrics?
A sponsor may highlight whichever metric looks stronger for a given deal. Comparing SPVs fairly generally means asking for both figures, along with the holding period, rather than accepting one number on its own.
