# What Is Unrealized IRR?

> Unrealized IRR is an internal rate of return calculated using current portfolio marks and expected future proceeds — not cash actually distributed to investors yet.

**Unrealized IRR** is an interim internal rate of return that blends actual distributions to date with the estimated value of holdings still in the portfolio — before those positions fully liquidate.

### How it works

Fund [IRR](/glossary/irr) needs dated cash flows: capital calls out, distributions in. For active funds, much of the "return" sits in [unrealized value](/glossary/unrealized-value) — shares marked at the last financing round, secondary indications, or public comparables. Unrealized IRR treats those marks as if you received them today (or on a modeled exit schedule), then solves for the rate that equates flows.

Mid-fund life, unrealized IRR often looks attractive when a few portfolio companies reprice upward in hot markets. A markdown on one large holding can swing the entire fund metric. Realized IRR, by contrast, uses only cash returned — no marks. [TVPI](/glossary/tvpi) captures multiple on capital but ignores timing; IRR captures timing but is sensitive to mark assumptions.

GPs report net unrealized IRR in quarterly LP letters. Benchmark providers rank vintages using blended metrics until funds mature.

### Why it matters

- **Founders:** Your round price affects an investor's unrealized IRR on your cap table — reason to care about fair, defensible valuations, not only headline numbers.
- **Investors:** LPs use unrealized IRR for pacing and re-up conversations but anchor decisions on DPI and realized track record. Paper IRR that never converts to cash is a recurring VC disappointment.

### Common mistake

Celebrating top-quartile unrealized IRR while DPI remains near zero — marks from insider rounds or optimistic 409A valuations may not survive the next down market or exit process.

## FAQ

### What is unrealized IRR in simple terms?

Unrealized IRR is the return rate implied by money still tied up in portfolio companies at their latest valuations, plus any distributions already received. It moves every time a company raises, gets marked down, or exits.

### Why does unrealized IRR matter?

It signals interim fund performance for fundraising and LP reporting. LPs treat it cautiously — high unrealized IRR with low DPI means most gains exist only on paper until exits land.
