Makerware - The free rendering program from Makerbot Ind. now has a function that will tell you how many grams of plastic your print will use with the print settings you give it.
Netfabb - A free, open source program for rendering has a function that tells you the volume of an object.

To get the cost of material per gram:

Take the price of a 1Kg spool of filament and divide it by 1,000. That is the price per gram of the material.
