21 April 2009 If the period is the same i.e. outflows and inflows relate to the same years take the net cash flow. IRR is concerned with net cash flow.

Suppose outflows and inflows for 5 years are:
1)-100,0; 2)-50,65; 3)-25,100; 4)-25,125; 5)-25,150 (outflows are negative and inflows are positive)

Net cash flows for the five years are:
-100,15,75,100,125

IRR = 49%
