Hey Pcunniff,
For Situational Awarenes (SA) I am using the TI BA 2 Plus Professional
If you are getting an error message on calculation of IRR, sounds like you might be forgetting the initial cash outflow of 7 million or forgetting to use the negative sign in the initial outflow. Here are the steps that I take and results I am getting:
[2nd] and [CE/C] (to clear anything prior)Hit [CF] button and type -7,000,000 hit [Enter] then hit [down] twice, enter the rest of the cash flows same way.Hit [NPV] and enter 12 and then press [Enter]Press [down] to get to NPV, then press [CPT]. I get 159,825.98 (rounds to 0.160 million)Press [IRR] and hit [CPT], I get 14.1537 (rounds to 14.2)Repeating process for Project two I get NPV of 205,493.80 and IRR of 13.7009
Hope this helps!
