In practice
Fund IRR is calculated from dated capital calls and distributions, plus remaining NAV, and is usually reported net of fees and carry. Gross IRR, which excludes them, is often confused with net. It is commonly paired with a multiple such as TVPI, which ignores timing. Early in a fund’s life, IRR is often distorted by the J-curve.
An example
Round numbers, not a real fundSay $100 million becomes $200 million after five years: an IRR of about 15%. If it becomes $200 million in three years, IRR jumps to about 26%.
Why it matters
It rewards speed, which is why managers can lift it with early sales or fund borrowing.
