Calculating IRR and NPV with different project lifespans

Now that you calculated the WACC, you can calculate and compare the IRRs and NPVs of each project.

While the IRR remains relatively comparable across projects, the NPV, on the other hand, will be much more difficult to compare given the additional year required for project 1.

Luckily, in the next exercise, we will introduce another method to compare the NPVs of the projects, but we will first need to compute the NPVs as before.

The cash flows for projects 1 and 2 are available as cf_project1 and cf_project2.
