From IRR(calculated from estimated figures), we can get where NPV=0.
Second, IRR is the required rate of return of the project,
when the project return(actual return) fall below the IRR(required rate of return of project) that you calculated before, that means that NPV
actual return这个概念,是在project实施之前就可以得到的吗?应该不是吧
既然如此,我们如何可以求出actual return呢?
还有,你说的actual return<required return, NPV<0,请问二者如何联系起来(从道理上我能理解但从公式上如何体现)?
