Pop on over to the calorie counters board and read the stickies at the top. There's tons of information and good resources there. You can also do a Google search for "calorie calculator" and come up with a BUNCH of links. I use the one at
http://www.freedieting.com .. but there are others everywhere.
Just keep in mind that the numbers you get are an estimate. Every one is a little different and while they give you a good starting point, you'll probably have to tweak things to suit your personal situations as you go along.
