    How should I calculate the attrition if the contract started in Oct 09 and now it’s only Feb. 10.  We have multiple sub contractor company  and we a big turn over the last 5 months.   
    For example:  We started with 49 people and now 4 people are leaving. Out of the 4 people 3 belong to one sub. contrator and 1 belong to another one.
    Should I still calcalute for the whole year?  How can I can calculate just by the current period?

    I guess your problem is that you want to calculate the (yearly) attrition rate already after a few months. You can use Survival Analysis to estimate the attrition in an early stage. If you have Minitab, look under Stat – Reliability/Survival – Distribution Analysis, and read the various examples in the “help” section.
