MoIC vs. IRR in Private Equity: What Each Measures and When Each Matters

Interviewers ask for both MoIC and IRR because they answer different questions. MoIC is the wealth multiple: dollars out divided by dollars in. IRR is the annualized rate that makes the NPV of those cash flows zero. You can have a deal that looks great on one and mediocre on the other. Hold period, dividend recaps, and exit timing all move IRR without touching MoIC. If you only memorize definitions, you will blank when they change the cash timing. If you can explain both on the same case, you sound like someone who has underwritten.

Definitions you should be able to say out loud

MoIC = Total Equity Distributions ÷ Initial Equity Invested

IRR = discount rate where NPV(all equity cash flows) = 0

MoIC does not care about timing. Invest $100M, get $300M back at exit, and MoIC is 3.0x whether that exit is Year 5 or Year 10.

IRR does care. The same 3.0x over three years is a very different IRR than over seven years, because capital is stuck for longer.

Gross vs net (say it if they push)

Interview answers are usually pre-fee / deal-level unless the prompt asks for net to LPs. Fund-level IRR after fees and carry is a different conversation. Do not volunteer a net number you cannot defend.

The paper LBO shortcut (and when it breaks)

If every cash flow is just entry and exit (no dividends, no partial sales), MoIC and IRR are linked:

IRR ≈ MoIC^(1 / Hold Years) − 1

At a five-year hold:

This is why paper LBO questions often give you one and ask for the other. The shortcut only works for a single terminal distribution. Add interim dividends, a dividend recap, or a partial exit, and you need a real cash flow schedule.

Quick derivation intuition

A 2.0x in five years means money roughly doubled. Doubling in five years is a bit under 15% compounded annually. You do not need a calculator in the room if you memorize a few anchors and interpolate.

When MoIC is the better story

Big equity checks and fund return of capital: a $400M equity check that returns $1.2B (3.0x) moves the fund's numerator even if IRR is "only" 22% because the hold slipped two years. LP reporting shows both, but deal teams often lead with MoIC on big winners because it communicates absolute profit.

Deals with a lot of interim cash: recaps and dividends can juice IRR without changing final MoIC if exit equity is unchanged. MoIC still answers whether you made money on the basis you underwrote.

Downside cases: a 0.8x MoIC is clearly a loss of principal. IRR on a losing deal with messy timing is harder to interpret in an interview.

When IRR is the better story

Competing uses of capital: two 2.5x deals where one exits in Year 3 and one in Year 7 are not the same to an allocator. IRR captures the cost of capital sitting around.

Carry and fund pacing: GPs care about IRR hurdles (and sometimes MoIC gates). Faster returns help raise the next fund.

Portfolio management debates: operating partners arguing for an earlier sale often point at IRR. CEOs arguing for another year of EBITDA growth often point at higher exit MoIC.

Same MoIC, different IRR (worked comparison)

Two simplified LBOs, each with 2.0x MoIC on $100M equity:

Both return $200M total on $100M invested if you count dividends plus exit. Deal B's IRR is higher because cash comes back earlier. Deal A is the "all at exit" profile you see on growthier assets with low near-term free cash flow.

What to say in the interview

"Same MoIC, higher IRR on Deal B because interim distributions reduced capital at work earlier. If the prompt only gives terminal MoIC, I use the power-law shortcut. If dividends exist, I need the full cash timeline."

Dividend recap: the classic IRR booster

A mid-hold recap that pulls equity out can:

• Raise IRR by returning capital early
• Leave less equity in the deal at exit
• Keep MoIC similar or change it depending on how you count total distributions vs remaining exit equity

Interviewers want you to notice the tradeoff: faster cash vs less equity left for the final exit, plus more leverage risk after the recap.

How this connects to returns attribution

MoIC decomposition (deleveraging, EBITDA growth, multiple expansion) explains where the multiple came from. IRR adds when the cash showed up. A recap that pulls equity forward without improving exit MoIC boosts IRR but can leave less equity in the deal for the final exit.

Useful paired answer:

"Attribution tells me whether the 2.5x was operations, leverage, or multiple. IRR tells me whether that 2.5x was earned quickly or slowly."

Common mistakes

Interview drills

1. 3.0x over 5 years: approximate IRR
2. 2.0x over 3 years vs 2.0x over 7 years: which IRR is higher and why
3. Same MoIC with a Year 3 dividend: what happens to IRR
4. Entry equity $200, exit equity $450, no interim cash, 4-year hold: MoIC and rough IRR
5. "Would you rather have 2.2x in 3 years or 3.0x in 6 years?" Pick and defend

Drill answers (approximate)

1. ~25%
2. 3-year is much higher IRR for the same MoIC
3. IRR rises; MoIC depends on whether you count the dividend in total distributions (usually yes)
4. MoIC = 2.25x; IRR a bit under the 2.5x/~20% five-year anchor because hold is shorter than 5 but MoIC is under 2.5x (ballpark high teens)
5. Defensible either way: 2.2x / 3y is roughly low-to-mid 20%s IRR; 3.0x / 6y is roughly ~20%. Many allocators take the faster compound if risk is similar.

How sponsors use both in an IC memo

A clean IC returns page usually shows:

• Entry equity and exit equity
• MoIC
• Gross IRR
• Returns attribution bridge
• Hold period
• Sensitivity on exit multiple and EBITDA

If the memo only shows IRR, ask what MoIC is. If it only shows MoIC, ask the hold and cash timing. Either gap is a diligence smell.

Practice on SheetRank

Build a full LBO with operating cash flow, debt paydown, and exit. Then compare MoIC and IRR if you add a mid-hold dividend recap versus holding all equity to exit. The gap between the two metrics is much easier once you have seen it in a live model instead of a flashcard. Project Apollo-style cases are built for that comparison.
