Ah, the Israeli workforce. It can be quite taxing. Literally.
My aliyah counselor-husband came to my rescue and found this site (put together by MLL PayWay, apparently), that calculates for Israeli wage-earners what you get paid and what kinds of taxes, and how much of it, your money is being sucked into.
It definitely helps with the American-turned-Israeli first-of-the-month taxation blues.
