Carried interest, explained

Carried interest, usually called "carry", is the share of investment profits that a private equity firm keeps after its investors have been paid back. In a typical PE fund, the Limited Partners (the investors) put up the capital. The General Partner (the PE firm) runs the investments. When the fund exits its deals and returns cash, the first money flows back to LPs until they have received their original capital plus a minimum annual return, usually 8%. After that hurdle is cleared, the GP takes 20% of every additional dollar of profit. That 20% is the carried interest. It is the economic engine that makes senior PE professionals wealthy, the reason LPs complain about alignment, and the subject of every tax-reform debate that has tried and failed to change it for the past 20 years.

That is the textbook answer. Here is what actually happens.

Why it is called "carried" interest

The name is a Renaissance-era shipping term. A ship's captain would take a percentage of the profits from the cargo he carried across the ocean, but only after the merchants who financed the voyage got their capital back. The captain's share was the "interest" he was "carried" on, meaning he did not put up the money for the goods, he just earned a share if the trip paid off. Modern PE carry works exactly the same way. The GP is the captain. The LPs are the merchants. The portfolio companies are the cargo. Whether the metaphor flatters anyone in that chain is a judgment call.

How the economics actually run

A typical PE fund is structured with two economic terms: the management fee and the carried interest.

Management fees are paid annually by LPs to the GP, usually 1.5-2% of committed capital. They pay for the firm's operating costs: salaries, offices, back-office, diligence expenses. Management fees are guaranteed, regardless of how the fund performs.

Carry is not guaranteed. It kicks in only after the LPs have received their money back plus a preferred return, commonly 8% per year (the "hurdle rate"). Once the hurdle is cleared, the GP catches up to an 80/20 split of cumulative profits, and from that point forward every additional dollar of profit is split 80% to LPs and 20% to GP.

Say a $5 billion fund returns $15 billion to LPs after ten years. The gross profit is $10 billion. After the hurdle and catchup mechanics clear, roughly $2 billion of that flows to the GP as carry. That $2 billion is split among the firm's partners and senior professionals according to their individual carry point allocations. A partner holding 5 points of carry in that fund earns $100 million.

Multiply this across the firm's multiple active funds over a career, and you get the arithmetic of how mega-fund partners become spectacularly wealthy.

The European vs American waterfall

There are two flavours of carry, and the difference matters more than people usually realise.

European-style carry (also called "whole-fund carry") calculates carry on the fund as a whole. The GP only takes carry after all LP capital across the entire fund is returned, plus the hurdle. This is better for LPs because the GP takes on the aggregation risk: if one deal loses money, it offsets gains on other deals before carry kicks in.

American-style carry (also called "deal-by-deal carry") calculates carry on each exit as it happens, with a clawback mechanism at the end of the fund's life. The GP gets carry earlier in the fund's life, but has to return overpayments if the later deals underperform. This is better for the GP's cash flow during the fund's life, worse if a few later deals blow up.

Most US buyout funds use American-style. Most European funds and secondaries funds use European-style. In recent years the LP base has been pushing back on American-style because of the clawback risk and the principal-agent issues it creates.

What "carry points" actually mean inside a firm

When a PE fund launches, the firm divides the GP share into "carry points", typically 100 total points per fund. These points are then allocated to individuals across the firm.

A rough distribution at a mid-sized fund might look like:

• Founder / managing partner: 20-25 points
• Senior partners: 8-15 points each
• Junior partners: 3-7 points each
• Principals: 1-3 points each
• VPs: 0.5-1 point each
• Associates: 0.25-0.5 points
• Analysts: usually nothing

One carry point on a $5 billion fund that returns 2x net is worth roughly $20 million over the life of the fund. A 10-point allocation for a senior partner is worth $200 million on paper, paid over 7-12 years as individual deals exit.

That is the paper value. The actual cash received depends on whether the fund performs, whether the individual stays at the firm long enough to vest, and whether the fund's vintage happened to align with a benign macro environment.

Vesting and good-leaver / bad-leaver

Carry grants almost always vest over time, typically 20% per year over five years. If you leave before year five, you forfeit the unvested portion.

Worse, many partnership agreements have "bad leaver" clauses that let the firm claw back even vested carry in certain scenarios, especially if you leave for a competitor. "Good leaver" status (retirement, death, disability, mutual departure) usually preserves vested carry. The firm's discretion in classifying a departure is considerable, and the threat of losing millions in vested carry is one of the most effective retention tools in the industry. For more on how this plays out in practice, see private equity compensation.

The tax treatment debate

In the US, carried interest is currently taxed as long-term capital gains (usually 20%, or 23.8% including the net investment income tax) rather than as ordinary income (up to 37%). The argument for preferential treatment is that carry is returns on invested capital, analogous to a founder's equity appreciation. The argument against is that carry is essentially a performance fee earned on other people's capital, and that treating it as capital gains is a policy loophole.

Every US administration since the 2000s has proposed closing the loophole. None has succeeded. The structural reason is that carried interest sits at the intersection of real estate, venture capital, private equity, and hedge funds, each of which has powerful lobbying. Changing it for one without changing it for all triggers a political fight nobody has won.

UK treatment is similar in effect (reformed periodically but still generally more favourable than ordinary income). European jurisdictions vary significantly.

Expect the debate to continue. Do not expect structural change to happen quickly.

When carry does not pay

For all the paper wealth that carry represents, there is a significant share of PE funds where carry pays materially less than modelled, and occasionally nothing.

A fund that returns 1.4x net to LPs over 10 years might clear the hurdle only marginally, resulting in very small carry. A fund that returns 1.2x net likely does not clear at all, and produces zero carry.

This matters because many PE professionals build life plans assuming their paper carry will materialise. Vintages from 2019-2021, priced during low-rate euphoria, are currently struggling. A meaningful share of those funds will underperform their modelled returns, and the carry projected for the partners who committed a decade to building them will not fully materialise.

The quiet conversation inside mega funds right now is which vintages will clear and which will not. The answer reshapes personal finances, retention, and the firm's ability to raise the next fund.

The alignment question

The standard argument for carry is that it aligns GP interests with LP interests. Both parties benefit when deals perform. This is mostly true.

The exceptions matter.

Management fees continue whether or not the fund performs, which dulls alignment during the capital-raising phase. A GP that has already raised a $10 billion fund earns $150-200 million a year in fees regardless of outcome. The incentive to deploy that capital quickly, even into marginal deals, is considerable.

Deal-by-deal carry creates incentive to sell winners early and hold losers. The GP banks carry on the winners, and the clawback on losers does not trigger until the end of the fund's life.

GP commitments (the capital the GP puts into its own fund) are supposed to strengthen alignment, and they do, but modern GP commitments are often 1-3% of the fund, financed from management fees. The real skin in the game is the carry itself.

The honest take

Carried interest is the cleanest explanation for why senior PE partners become so wealthy. It is also the cleanest explanation for why the industry produces the behaviours it does: aggressive pricing of deals, use of dividend recaps to de-risk returns early, willingness to pile on leverage via PIK financing, reluctance to walk away from marginal deals when there is fund capital to deploy.

If you change how carry is structured or taxed, you change the whole industry. Every reform proposal has run into this reality. The incentives are baked into the structure.
