Dear PM Advisor,
What percent of questions need some calculation in the PMP exam?

Dear Math Geek,
I wish it were all of them. Because I know when I get those correct. The philosophical questions test to see if you can think the same way as the PMI so there is more uncertainty there.
That being said, let's see what questions are likely to require calculations:
1 - 2 about number of communication channels (just remember C = n(n-1)/2)
1 - 2 Earned Value scenarios, each with 3 - 5 questions associated
1 - 2 Net Present Value questions
2 - 3 Cost Plus Fee questions
1 - 2 Normal distribution/6 sigma questions
2 - 3 PERT questions (just remember Pert = (O + 4*ML + P)/6)
And if you consider Network Diagramming calculations, 1 -2 of those with 3 - 5 questions in each
So you are looking at a range of 13 - 32 calculation questions within the 200. Most likely these are all within the 175 questions that count so around 15% of your questions require calculations and you can check your work to ensure you got them right.
