The Irr Converts The Npv Into A %. This Is Done Because People Are More Familiar With Rates Of Rates Of Interest So Understand More Clearly That Borrowing At 10% And Investing At 13 % Is Good For Example.
Whereas Borring At 10% Getting A Npv Of $52,000 May Not Be So Obvious.
The Irr Is The Point Where The Npv Is O.
L : Is The Lower Rate Of Increase - Example 10%
H : Is The Higher Rate Of Increase - Example 20%
P : Is The Positive Npv : Example 52,261
N: Is The Negative Npv : Example 119,846
Formula Will Be : L + [ P/ P - N X ( H - L ]
So 10% + [ 52,261/52,261 + 119,846 X ( 20% - 10%)
You Have Your Irr.
