What Is a Carried Interest Calculator?

A carried interest calculator runs the profit waterfall that sits at the heart of every private equity, venture capital and hedge fund agreement. Investors commit capital, the manager invests it, and when the investments are sold the proceeds are distributed in a strict order: capital first, then the preferred return, then the manager's catch-up if the terms include one, and finally a split of what remains. The calculator turns that legal language into numbers so both sides can see who receives what.

The tool models a single deal simply and transparently. It is most useful for understanding how the pieces interact: how a higher hurdle shifts money from the GP to the LPs, how a full catch-up restores the GP's share, and how many millions of dollars of management fees are paid before the performance split is ever considered.

How It Works

The model deducts management fees, charged on invested capital for the length of the holding period, from the exit value. The remaining proceeds are reduced by the original capital to give total profit. The preferred return is computed by compounding the hurdle rate annually over the holding period and is allocated pro rata to each partner's contribution.

Anything left above the hurdle enters the catch-up calculation. The GP's goal is to hold the carry rate times the sum of the preferred return and the catch-up amount. With a 100% catch-up, each dollar of profit during the phase goes to the GP until that target is reached, which requires a catch-up pool of the carry rate times the preferred return divided by one minus the carry rate. A 50% catch-up takes twice as large a pool because the GP receives only half of each dollar distributed. With no catch-up the GP proceeds straight to the residual split.

Once the catch-up target is met — or the available profit is exhausted — everything further is split at the carry rate: typically 20% to the GP and 80% to the LPs. The final figures show what each side receives, what multiple of its capital each side earned, and what percentage of the total gain the GP actually captured as carried interest.

Understanding Your Results

The primary card shows the GP's carried interest with the effective carry percentage, which is often well below the headline rate because the hurdle is paid out of the same profit pool. The three statistics beside it show the profit above the hurdle, the LPs' multiple, and total profit created. The waterfall table walks each tier in order, showing the size of the pool and how it was divided.

In the default scenario a $100 million fund exits at $260 million after six years. Fees absorb $9 million, leaving $251 million and $151 million of profit. An 8% hurdle requires roughly $58.7 million of preferred return, and a full catch-up then hands the GP about $14.7 million before the residual is split. The GP's carried interest lands near $33 million, or roughly 22% of the profit — slightly above the headline rate only because the GP also earns preferred return on its own commitment. Summary Statistics breaks out each element, including the effective carry and the LP profit, so you can test alternative terms before signing anything.
