What Is Carried Interest? (2 and 20 Explained)

Carried interest is one of the most consequential ideas in finance and one of the simplest, once the jargon is stripped away. It is how the people who manage other people's money get rich when they do it well.

The two numbers

Most private equity and hedge funds are paid on a model called two and twenty.

The two is the management fee: roughly 2 percent of the assets under management, charged every year, regardless of performance. It pays salaries, rent and the cost of running the fund.

The twenty is the carried interest, or carry: about 20 percent of the fund's profits, paid to the manager as their reward for generating them. This is where fund managers make their fortunes. On a fund that turns 1 billion dollars into 2 billion, the 1 billion of profit yields up to 200 million of carry, before the hurdle described below.

The management fee is a certainty. The carry is the incentive. The whole design is meant to align the manager with the investor: the manager only gets seriously rich if the investors do first.

The guardrails: hurdle and high-water mark

If carry were simply 20 percent of any gain, a manager could collect a fortune for a mediocre result. Two mechanisms prevent that.

A hurdle rate, or preferred return, sets a minimum return the investors must receive before the manager earns a cent of carry, commonly around 8 percent in private equity. Below the hurdle, all gains go to investors. Only above it does the 20 percent split begin, usually after a "catch-up" that lets the manager draw level. This means carry rewards genuine outperformance, not just showing up in a rising market.

A high-water mark, common in hedge funds, ensures the manager only earns carry on new profits. If the fund falls, it must recover past its previous peak before performance fees resume. Without it, an investor could pay carry on the same gains twice, once on the way up, again after a loss and recovery.

Why the structure matters

The fee model is not a detail; it shapes behaviour. Carry gives a manager a powerful reason to grow the fund's value, which is good. But it can also tempt a manager toward outsized risk, because they share in the upside and not the downside, which is why hurdles, high-water marks and a manager's own capital in the fund all matter.

For an investor, and especially a family office deciding whether to allocate to a fund or invest directly, understanding two and twenty is essential, because fees compound against you exactly as returns compound for you. Over a decade, the gap between paying 2 and 20 and investing directly can be enormous. That arithmetic is a large part of why sophisticated families increasingly co-invest alongside funds at reduced fees, or build the capability to do direct deals themselves.
