I want to provide a MIRR and an IRR analysis for the implementation of
proposed systems. As such I have 5 years of expenses for the analysis period
and 5 years of revenue. All of these values are from the year-end.

How do I setup the IRR and MIRR parameters. The function prototypes (and the
Excel help) slightly confuses me concerning the values parameter:
MIRR(values,finance_rate,reinvest_rate)

IRR(values,guess)

Thanks in advance for your adivce,

Rick
