I am facing problem with the calculation of IRR on my new 10bII.

The IRR computation is wrong.

To compute IRR of the following cash flows: - -11 + 12 / ? Where NPV is 0

The process I keyed in is

Shift clear all
11 (+ / -) CFj
12 CFj
Shift IRR / YR

The answer I get now is 109.0909

This is obviously wrong. I used to get 9.0917 percent.

Can you kindly advise?

Answer:

Hi Brian,

You need to set the P / YR to 1. The default is 12.

1 Shift P / Yr

Shift c all ‘Screen should display 1’

11 (+ / -) CFj

12 CFj

Shift IRR / YR ‘Screen should display 9.0909’
