Unlevered IRR

Does anyone know of an unlevered IRR formula for converting a levered IRR?

I'll explain my goal. PE managers usually underwrite 20-25% returns for the portfolio companies on a levered basis. I am trying to derive an unlevered IRR formula and use it as an EBITDA growth rate for the company. For example: EBITDA at acquisition * (1 + unlevered IRR)^(holding period) = EBITDA at exit

I found this formula for unlevered IRR:

levered IRR = unlevered IRR + (unlevered IRR - cost of debt) * (Debt / Equity)

I would define levered IRR for either 20% or 25%, get the average cost of debt for that period, and the companies debt to equity ratio, then solve for the unlevered IRR.

What does you guys think about this formula? Does it work?

i'm asking if the formula and method makes sense. I just found it randomly online, I'm not going to assume its correct just because some random person put it online... I wanted to see if other random people online agree with it, then i'll accept it.

 

Yes. But how do I have to deal with recapitalization? If the deal had been funded by equity only, recapitalization would not have occurred!

As regard of value levers, in case I compute the levers making reference to equity only (therefore not considering debt at the entry), what does the leverage effect mean?

 

I mean, I want to compute value levers. Since the case is complex I would like to separate up the two investments from the beginning considering the equity value at the beginning of the two companies. But if I consider the cases in this way, the deleverage effect makes sense?
