– A project has an initial outflow followed by years of inflows. What would be the effect on NPV and IRR of an increase in the cost of capital?
1. The answer is NPV would decrease and IRR would have no change. -With regards to the IRR, how come that there is no change? With an increase in cost of capital it would cost us more therefore the “break even” cost of capital would increase as well.
The IRR is the rate of interest for which the NPV is zero.
We would then compare the cost of capital to the IRR to see whether or not the project is worthwhile, but the cost of capital does not affect the calculation of the IRR at all.
