I’ve spent 2-3 hours going over GiveWell’s cost-effectiveness spreadsheet, so don’t expect to understand it immediately. GiveWell has a video explaining how the 2015 spreadsheet works. I haven’t much looked at the 2016 spreadsheet but it looks a lot better designed so it shouldn’t take as long to understand.
