Fund Economics & Waterfall

The distribution waterfall is the mechanism that determines exactly how profits flow from the fund to LPs and the GP. It is one of the most important and most frequently misunderstood concepts in PE. 'The GP gets 20%' is a common shorthand, but the reality involves a specific sequence of steps that must be followed in order, with each step triggering only after the previous one is fully satisfied.

Think of it literally as a waterfall: money flows downward through a series of tiers. It fills the first tier completely before spilling over into the next. Each tier represents a different allocation of cash between LPs and the GP. The structure ensures that LPs are 'made whole' before the GP participates in the upside.

The Four Tiers of a Standard Distribution Waterfall

The most common PE waterfall has four tiers (sometimes called 'buckets' or 'tranches'):

Tier 1: Return of Capital
All distributions first go to LPs until they have received back 100% of their invested capital (the amount they actually wired to the fund via capital calls). Management fees and expenses that were funded from capital calls are typically included in this figure. Until every dollar of called capital is returned, the GP receives nothing.

Tier 2: Preferred Return (Hurdle)
After LPs have their capital back, additional distributions go to LPs until they have received their preferred return, typically 8% per year on their invested capital, compounded annually. This preferred return accrues from the date capital was called to the date it was distributed. The purpose is to ensure LPs earn a minimum time-value-of-money return before the GP shares in any profits.

Tier 3: GP Catch-Up
Once LPs have received their capital back plus the 8% preferred return, the next distributions go 100% to the GP until the GP has received 20% of all cumulative profits distributed to that point (i.e., the profits from Tier 2 plus Tier 3). This 'catch-up' exists because in Tiers 1 and 2, the GP received nothing. The catch-up brings the GP's total share up to their entitled 20% of all profits. Some funds use an 80/20 catch-up (rather than 100/0) which is slightly more LP-friendly.

Tier 4: Carried Interest Split (80/20)
After the catch-up is complete, all remaining distributions are split 80% to LPs and 20% to the GP. This 20% is the carried interest, and this tier is where most of the carry dollars accumulate in a successful fund.

Whole-of-Fund (European) vs. Deal-by-Deal (American) Waterfalls

There are two fundamentally different approaches to when carry is calculated:

European / Whole-of-Fund Waterfall
Carry is calculated on the entire fund's aggregate performance. The GP does not receive any carry until LPs have received back all invested capital across all deals plus the preferred return on the total fund. This means that if the fund has some winners and some losers, the losses reduce the carry pool. This approach is more LP-friendly and has become the global standard.

American / Deal-by-Deal Waterfall
Carry is calculated on each individual deal as it is exited. If Deal A returns 3x, the GP earns carry on Deal A immediately, even if Deal B later returns 0.5x. The GP gets paid earlier but may end up owing money back if later deals underperform (see: clawback). The American waterfall was common in the early days of PE and is still used by some U.S. firms, particularly in venture capital.

The key risk with the deal-by-deal approach is that the GP may receive carry on early winners and then later deals lose money. The clawback provision is designed to address this, but in practice, collecting clawback payments from individual GP partners can be difficult.

The distribution waterfall is the math that turns a fund's investment performance into actual cash in the pockets of LPs and the GP. The four-tier structure (return of capital, preferred return, GP catch-up, and 80/20 split) ensures an orderly and fair allocation of proceeds. Whether a fund uses a European or American waterfall has significant implications for when the GP gets paid and how much risk LPs bear from uneven deal outcomes. Clawback provisions serve as a backstop but are imperfect in practice. As you evaluate PE fund terms, the waterfall structure should be one of the first things you examine. In the final lesson of this module, we will explore the people behind the fund: the team structure from analyst through managing partner, and the specialized roles that make a PE firm function.
