Hedge fund vs index.

Hedge fund vs index fund calculator compares net returns after notorious 2-and-20 fee structure (2% management + 20% of profits) vs cheap index fund. Famous bet: Warren Buffett bet 1M that S&P 500 index would beat any hedge fund portfolio over 10 years. He won decisively - S&P returned 7.1%/year vs hedge funds 2.2%/year.

Example: 100k invested 10 years. Hedge fund 8% gross, 2% fee, 20% performance fee = ~4.8% net effective. Final value 160k. Index fund 7% return = 197k. Index fund wins by 37k despite 'lower' headline return - because hedge fund fees ate most of the alpha.

Hedge fund problems: (1) 2-and-20 fees are crushing - need 10%+ gross to net 6% (vs 7% S&P 500). (2) Most hedge funds underperform index over 10 years (SPIVA studies confirm). (3) Liquidity restrictions (lockups, gates). (4) Survivorship bias inflates reported returns. (5) Access requires 1M+ minimum and accredited investor status. For 99% of investors, low-cost index funds are mathematically superior.

Quick example

With investment amount of 100,000 and hedge fund gross return of 8% (plus hedge fund management fee of 2% and performance fee of 20%), the result is -36,901.87. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Investment Amount, Hedge Fund Gross Return %, Hedge Fund Management Fee %, Performance Fee %, and Index Fund Return %. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.

What's happening under the hood

Hedge net = gross - mgmt fee - performance fee on excess. Compound at net rate. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why investors run this

Most people's intuition for compounding is wrong — not because the math is hard, but because linear thinking doesn't account for curves. Running numbers through a calculator like this one is the cheapest way to recalibrate that intuition before making an irreversible decision about contribution rate, asset mix, or retirement age.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.
