056Which yields a greater return, an IRR of 25 percent over 5 years or an IRR of 30 percent over 3 years?Centerview PartnersGeneralist · New York · 2026
Say this
The 25 percent over five years returns more total money: about 3.05 times against about 2.2 times. But the 30 percent is the better rate of return, so the answer depends on whether you can redeploy the capital.
Then walk it
- 1.25 to the fifth is roughly 3.05 times. 1.3 cubed is roughly 2.2 times. So more absolute money from the longer hold.
- But IRR is an annualised rate, and 30 percent beats 25 percent per year of capital employed.
- The deciding question is reinvestment. If you can put that capital straight into another 30 percent deal for the remaining two years, the short hold wins comfortably: 2.2 times 1.69 is about 3.7 times.
- If the capital sits in cash for two years, the long hold wins.
- This is exactly why limited partners care about both IRR and multiple on invested capital, and why a fund with spectacular IRR from fast flips can return less cash than one with lower IRR and longer holds.
Where candidates lose it
Answering with only one of the two framings. The question is deliberately ambiguous, and the right move is to compute both, then name reinvestment risk as the thing that decides it.
Expect next
- So which would a limited partner prefer?
- Why do funds report both IRR and MOIC?
- How would you game an IRR?
