Jon,

Calculating the bulk percentage is pretty useless and rather may be
deceptive. However, if you still want to do it, then all you have to
know if the amount of solder in the joints (half of the printed
amount of the solder paste) and the thickness of gold plating
on the board and/or component  with their geometrical dimensions.
