IRR vs MOIC: Key Differences Explained

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. Formally, IRR is the discount rate that sets the net present value of all fund cash flows — capital calls out, distributions and residual NAV back — to zero. That definition matters in practice: interim IRRs on young funds are computed against unrealized NAV, so they can swing sharply as marks move. Subscription credit lines also flatter IRR by delaying capital calls, which is why sophisticated LPs increasingly ask to see IRR both with and without the facility's effect before comparing managers.

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. MOIC sits inside a family of multiples LPs read together. TVPI (total value to paid-in capital) is the fund-level multiple against called capital; it splits into DPI (cash actually distributed) and RVPI (remaining unrealized value). A 3.00x TVPI built mostly of DPI is fundamentally stronger than a 3.00x that is mostly RVPI — paper marks can come down, distributed cash cannot. Also distinguish gross MOIC (deal level, before fees) from net MOIC (what LPs actually keep after management fees and carried interest); the gap between the two commonly runs half a turn or more over a fund's life.

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. For emerging managers raising Fund II or III, the practical answer is that DPI and MOIC open LP meetings and IRR closes them. Early in a track record, IRR is too noisy to carry weight — a single fast markup on a small position can print a triple-digit IRR that no allocator takes at face value. A credible multiple on meaningful invested capital, with some cash actually returned, does far more work than a spectacular annualized rate on an eighteen-month-old portfolio.

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. Now run both metrics on one set of cash flows. A fund puts $10M into a company at close. The position returns $5M via a secondary sale at the end of year 2, then a final $25M distribution at exit at the end of year 6. MOIC = ($5M + $25M) ÷ $10M = 3.00x. IRR solves $10M = $5M/(1+r)² + $25M/(1+r)⁶, which gives r ≈ 24.3%. Now delete the early distribution and pay the full $30M at year 6 instead: MOIC is still exactly 3.00x, but IRR falls to 3.00^(1/6) − 1 ≈ 20.1%. Same multiple, same total dollars — that gap is purely the reward for returning $5M four years earlier. This is why GPs like early secondaries and why LPs read a high-IRR, modest-MOIC fund with some suspicion: the annualized number can be manufactured with timing in a way the multiple cannot.
