What a waterfall does
A distribution waterfall is the order in which a deal pays out cash. Money flows into the top tier until that tier is satisfied, then spills into the next one. Each tier says who gets paid and in what proportion.
The point is alignment. Limited partners (LPs) put up most of the equity, so they get their money and a baseline return back first. The general partner (GP) earns a larger share of profits only after the deal clears those hurdles. That extra share is the promote, also called carried interest.
The waterfall lives in your operating agreement or limited partnership agreement. Not in the pitch deck, not in the model. When the two disagree, the agreement wins, so the most useful thing you can do is make the model read exactly like the document.
Tier 1: return of capital
Most waterfalls return contributed capital to investors before any profit split. Every dollar an investor put in comes back to them, pro rata to their contributions, before the GP earns a promote.
Ordering varies. Some agreements pay the preferred return first and return capital second; some combine the two into one tier. Operating cash flow and capital events (a sale or refinance) can also follow different waterfalls. A common syndication pattern pays the pref from operating cash flow and returns capital mainly from a refinance or sale. Read the definitions of "Distributable Cash" and "Capital Proceeds" before you model anything.
Tier 2: the preferred return
The preferred return, or pref, is the return investors must receive before the GP shares in profits. It is usually stated as an annual percentage of unreturned contributed capital, and the rate is set deal by deal in the operating agreement. It is a priority of payment, not a guarantee: if the deal never produces the cash, the pref is not paid.
Two choices in the agreement change the numbers a lot:
- Simple vs compounding. A simple pref accrues on unreturned capital only. A compounding pref adds unpaid pref to the base, annually or quarterly, so the shortfall itself earns the pref rate. On $10,000,000 at 8% for three years with nothing paid along the way, simple accrues $2,400,000 and annual compounding accrues $2,597,120.
- Cumulative vs non-cumulative. A cumulative pref carries any unpaid amount forward until it is paid. A non-cumulative pref is lost if the period’s cash does not cover it. Most real estate deals use a cumulative pref.
- The base. "Unreturned capital" shrinks as capital comes back, so the pref shrinks too. "Contributed capital" does not. One word in the definition changes every year of the model.
Tier 3: the GP catch-up
A catch-up lets the GP receive a large share of distributions, up to all of them, after the pref is paid, until the GP has received its target share of all profits distributed so far. Once it has caught up, cash moves to the regular split.
Without a catch-up, an "80/20 split after an 8% pref" means the GP earns 20% only of profits above the pref. With a full catch-up, the GP ends up with 20% of all profits, pref included, as long as the deal earns enough to fund the catch-up. The worked example below shows the difference in dollars.
Catch-ups are standard in private equity and many real estate funds. They are less common in single-asset syndications, where many sponsors skip them to keep the LP story simple.
Promote tiers
After the pref (and any catch-up), cash is split between LPs and the GP. Many deals step the GP’s share up as performance improves. For example: 80/20 until LPs reach a 15% IRR, 70/30 until they reach 20%, and 60/40 after that.
Each split applies only to the cash inside its band. Reaching the 20% hurdle does not re-split earlier dollars at 60/40. Also check whether the split is measured on the LP class only or on all equity including the GP’s co-investment, and whether the GP’s co-invest sits in the LP class and earns the pref like everyone else.
IRR hurdles vs equity-multiple hurdles
An IRR hurdle measures the annualised return to LPs, reflecting the timing of every cash flow. It rewards speed. A quick sale can clear a 15% IRR hurdle with modest dollar profits, which can pay the GP a promote on a deal that returned, say, 1.3x.
An equity-multiple hurdle measures total dollars back divided by dollars in, and ignores time. A 1.8x hurdle is met whether it takes four years or ten, so a slow deal can promote the GP on a weak annual return.
Some agreements require both: the LP must reach, for example, a 15% IRR and a 1.6x multiple before the next tier opens. Whatever the test, define the cash flows it uses: dates, whether fees are included, and whether it is measured per investor, per class or for the deal as a whole.
American vs European waterfalls
In a European, or whole-fund, waterfall, investors get back all contributed capital across the fund, plus the pref, before the GP earns any promote. The GP waits longer, but over-distribution is unlikely.
In an American, or deal-by-deal, waterfall, the GP can earn a promote on each investment as it is realised, even while other deals in the fund are underwater. That is faster for the GP and riskier for LPs, so American waterfalls usually come with a clawback: at the end of the fund, the GP returns promote it received beyond its agreed share, often net of taxes it paid. A clawback is only as good as the GP’s ability to pay, so some LPs ask for escrow or personal guarantees.
Syndicators sometimes use "American" loosely to mean any waterfall that pays the promote from operating cash flow before capital is returned. Define the term in your documents rather than relying on the label.
A worked example
LPs contribute $10,000,000. The GP earns promote only. The deal has an 8% simple, cumulative pref, a 100% GP catch-up to 20% of profits, then an 80/20 split. Nothing is distributed for three years, then a sale produces $16,000,000 of distributable cash.
Totals: LPs receive $14,800,000 (a 1.48x multiple and roughly a 14% IRR). The GP receives $1,200,000, which is exactly 20% of the $6,000,000 profit. Without the catch-up, the $3,600,000 left after the pref would split 80/20, and the GP would receive $720,000 instead.
| Tier | To LPs | To GP | Cash left |
|---|---|---|---|
| Start | — | — | $16,000,000 |
| 1. Return of capital | $10,000,000 | $0 | $6,000,000 |
| 2. 8% pref, simple, 3 years | $2,400,000 | $0 | $3,600,000 |
| 3. GP catch-up at 100% | $0 | $600,000 | $3,000,000 |
| 4. 80/20 split | $2,400,000 | $600,000 | $0 |
| Total | $14,800,000 | $1,200,000 | — |
Common mistakes
Most waterfall disputes come from a handful of avoidable errors:
- The model and the agreement disagree on tier order, the pref base or the compounding period.
- Interim distributions are treated as pref in the model and as return of capital in the agreement, or the reverse.
- Day counts are ignored. Capital contributed on different dates accrues the pref from different dates.
- The catch-up is modelled as a percentage of cash rather than as a target share of cumulative profits.
- IRR hurdles are tested on deal-level cash flows when the agreement tests them per investor or per class.
- Fees are left out. Acquisition, asset-management and disposition fees change what is distributable.
- Spreadsheets get re-keyed each quarter, and a formula silently stops covering new rows.
