If they won't tell you what percentage you're getting, just ignore that part of the equation and base your estimate on everything else, like salary and health benefits. Most companies issue about 10 million shares, or more, so 30,000 would come at about .3%. If they sold the company for 20 million dollars, you'd gross about $60,000 in options, and probably net around $10,000 after capital gains and stuff. Give or take an order of magnitude. Just a very rough back of the napkin.
