Can I also ask a question with regards to NPV? How would you calculate it if you are told that the revenues and costs occur evenly throughout the year for 7 years? I was told not to calculate it for 12 months, instead just use the semi-annual discount factor. That is fine that I use ^0.5 ^1.5 so on for the discount factor formula, but shall I put it in for the end of the years too? So I would have 14 periods… Is this correct? Thank you!
