Comparison
IRR vs MOIC: Key Differences Explained
IRR (Internal Rate of Return) measures the annualized return on an investment accounting for the time value of money; MOIC (Multiple on Invested Capital) measures the simple multiple of money returned. IRR favors fast returns; MOIC rewards total absolute gain. Both are essential for evaluating VC fund performance.
What is IRR?
IRR (Internal Rate of Return) is the annualized rate at which an investment grows, accounting for when cash flows in and out. It's the venture equivalent of a compound annual growth rate — it penalizes slow returns and rewards quick wins.
A 30% IRR means every dollar invested grew at 30% compounded annually. IRR is highly sensitive to timing: the same 3x return produces a 44% IRR over 3 years but only a 20% IRR over 6 years.
IRR is the primary metric LPs use to compare VC funds against other asset classes (public markets, private equity, real estate). An IRR above 20–25% is considered good for venture; top-quartile funds target 30%+.
Example: A $1M investment returned $4M after 5 years = 32% IRR. The same $4M after 8 years = 19% IRR.
What is MOIC?
MOIC (Multiple on Invested Capital) is the simple ratio of total value returned to total capital invested. It answers the question: 'For every dollar we put in, how many dollars did we get back?'
Formula: MOIC = Total Value Returned / Total Capital Invested.
A 3x MOIC means you tripled your money. MOIC ignores time — a 3x MOIC in 3 years and a 3x MOIC in 10 years are the same MOIC but radically different IRRs.
MOIC is intuitive and easy to communicate: 'We invested $100M and returned $350M — a 3.5x fund.' LPs track both MOIC (total dollars returned) and IRR (return quality). Top-quartile VC funds typically target 3x+ MOIC.
Example: A fund invests $50M and returns $175M. MOIC = 175/50 = 3.5x. No time dimension needed.
Key Differences
| Feature | IRR | MOIC |
|---|---|---|
| What it measures | Annualized return rate (time-weighted) | Total return multiple (no time dimension) |
| Formula | Discount rate that makes NPV = 0 | Total value returned / capital invested |
| Time sensitivity | Highly sensitive — same MOIC at different speeds = different IRR | Not time-sensitive — 3x in 3 years = 3x in 10 years |
| Favors | Quick exits and fast capital return | Absolute dollar return, regardless of speed |
| Used by | LPs comparing VC to other asset classes | GPs communicating total fund performance |
| Limitation | Can look great if you return small amounts fast, even with modest MOIC | Can look great if you hold winners long, even with low IRR |
| Industry benchmark | >20% good, >30% top-quartile | >3x good, >5x exceptional |
When Founders Choose IRR
- →LPs comparing VC fund performance against public market equivalents or private equity
- →Evaluating early liquidity (DPI) — IRR improves significantly when distributions come early
- →Assessing a fund manager's historical track record across fund vintages
- →Calculating the time value of capital tied up in long-duration investments
When Founders Choose MOIC
- →Reporting total fund performance to LPs — MOIC shows absolute dollars created
- →Evaluating a single portfolio company investment at exit
- →Communicating fund results simply: '3.5x fund' is easier than explaining IRR
- →Assessing fund returners — which companies returned the fund or more
Example Scenario
Two funds each invest $100M. Fund A invests in fast-moving consumer companies and returns $250M (2.5x MOIC) over 5 years — generating a 20% IRR. Fund B invests in deep-tech and returns $350M (3.5x MOIC) over 12 years — generating a 13% IRR.
Which is better? By IRR, Fund A wins. By MOIC, Fund B wins. An LP would factor in public market returns over the same period, capital efficiency, and their own liquidity needs before deciding.
Common Mistakes
- 1Quoting IRR on a single deal with limited data — IRR is most meaningful for full fund performance, not individual investments
- 2Ignoring the J-curve effect — funds have negative IRR early in their life before investments mature
- 3Comparing IRR across funds without accounting for vintage year — a 2009 fund and a 2021 fund faced radically different market conditions
- 4Treating high IRR from early small exits as a proxy for fund quality — returning capital fast on small positions inflates IRR
- 5Forgetting that MOIC and IRR together tell the real story — strong MOIC with poor IRR usually means great investments held too long
Which Matters More for Early-Stage Startups?
Both matter and tell different parts of the story. MOIC is the intuitive first filter — did the fund make money? IRR is the second filter — was that money made efficiently relative to time?
For founders, MOIC is more directly relevant when evaluating how your investors think about exits. A fund with a 3x MOIC target needs your company to return significant multiples; a fund focused on IRR may push for earlier liquidity. Understanding which metric your investors prioritize helps you predict their behavior at exit decision points.
