I want to compare the profitability of a project vs. the profitability of cash in a savings account.

What are the differences between the IRR and MIRR methods? Could you include other methods in your comparison, if they exist?

no ;-) I'm creating a tool to compare the profitability of a photovoltaic project with a bank saving account. I need to be sure that I use the most appropriate method. Thanks in advance – si2w Feb 19 at 7:26
