Hedge Fund vs Index Fund Calculator

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 most investors, the fee gap is the decisive factor, and broad low-cost index funds carry far lower fees than the 2-and-20 structure.

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. Flipping each value past a round threshold shows which input moves the result most.

What's happening under the hood

Hedge net = gross - mgmt fee - performance fee on the post-management return. 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 run this

Running the numbers makes the trade-offs concrete. Small changes in the inputs can move the result more than intuition suggests, which is hard to judge without working it out.

What this doesn't capture

This is a simplified model that holds its assumptions constant. Real outcomes vary with market conditions, costs, taxes, and timing, so the figure is best read as one scenario rather than a forecast.
