Compression has a *.9 or -10% damage penalty if the price of the item does not pay for compressed equipment and the MC bonus' +10% extra cost.
Its a rare find that items don't pay for compression and/or MC, such an example are Shadowpegasus, Shadowpony, Shadowunicorn, which are MC, but don't pay for the *2 price of compressing two elements, therefore they deal *.95 damage.
Compression generally pays for three compressed slots at maximum, such an example is Tribal Shaman's three skills.
Examples of compression stretched to its limits are Ultimate Dragon Scythe of Elements, whose MC reduced the penalty by 5%, and Golem Summoner takes an additional *.95 penalty for having a trigger, the summonable Golems pay *1.2 upkeep for compression if used outside of the Golemancer armor.
