Challenge with BA 2 Plus

[hsing]

Hi,

I went ahead and bought the BA 2 Plus financial calculator. Probably the best $30 I've spent - and I'm just learning the tutorials! After going through InstantCert and watching the first (out of three) Standard Deviants DVDs, I was pretty intimidated by the formulas. A lot to remember, not considering the math! With this baby, I have hope again! :^) - if I can learn how to use it.

Thanks to japprend, there is a post in the Principles of Finance feedback section here at InstantCert (http://www.instantcertonline.com/forums/...sst-2.html) that recommends a great website with video tutorials for learning the BA 2 Plus - http://movies.atomiclearning.com/k12/ti_ba2

The tutorials at http://movies.atomiclearning.com/k12/ti_ba2 are great, but I'm having a challenge completing a computation in Section B, #5. The instructor finishes calculating NPV and moves on to IRR (in the same problem). After computing IRR, he says to press the down arrow to calculate MIRR. But, nothing happens when I press my down arrow (there's only one). His calculator has an up/down arrow (in the screen), and he mouses over the down arrow (on the keypad) and presses it with the calculator changing screens. My calculator doesn't have the up/down arrow (in the screen) and pressing the down arrow (on the keypad) doesn't make the calculator change screens.

The BA 2 Plus manual only seems to cover NPV and IRR for cash flows. (Maybe MIRR isn't that important anyway?)

Is it possible that 1) I'm not doing something right, 2) The tutorial is missing something or is wrong, or 3) There's something wrong with the calculator?

Thanks a lot!

Hi hsing,

The "BAII+ Professional" model appears to have this MIRR function (Modified Internal Rate of Return). The basic model "BAII+" does not. However, the procedure for NPV and IRR described in the video works perfectly up until the point where he tells us to hit the down arrow to display "RI"....that's the point where nothing happens on the BAII+.

That being said, you probably won't need to calculate MIRR on the exam....at least, I didn't. Knowing how to input the values, and calculate NPV and IRR will be sufficient.

So I wouldn't worry too much about MIRR.

Hope that helps,

Ah ha. Good to know. Thanks!
