Sir how can I calculate sensitivity analysis for cost of capital?
Say Cost of capital 8%, IRR 18%, NPV $1024
(Ans: Cost of capital an increase by 132% before NPV becomes negative)
We use the normal logic.
At 8% the project is worthwhile because the NPV is +’ve, and if the cost of capital increases then it will remain worthwhile for a cost of capital up to 18% (when the NPV will be zero).
So we can afford the cost of capital to increase by 10 percentage points (18 – 8) from an existing 8%.
In percentage terms this is an increase of 10/8 x 100% = 125%
(The answer you have written is wrong, or alternatively the question is copied wrong 🙂 )
I do go through an example of calculating sensitivities, including that of the cost of capital, in the free lecture.
Thank you for your help. I have checked a couple of times and what I have copied is absolutely right and it is exactly how mentioned in the question. 🙂
But it is clear now.
It must be a typing error in your book 🙁
Anyway, I am pleased that it is now clear.
