I calculated my BMR, and it came out to 2500 calories. If I want to lose weight should I be eating about 500 less than that? Or should it be like 200-300? I do do cardio so that is burning some off there too.

You want to eat a certain amount of calories under your maintenance, which is your BMR multiplied by an "activity multiplier." If you eat under your BMR you will find yourself quickly running short on energy...not to mention any gains you've made.

You have your BMR, right? Now take the correct activity multiplier and you have your maintenance.

okay that says 3875. That is a ton. So I should be eating about 3375 to lose weight? I've been eating 2000. Is that bad?

Depending on how long you have been doing the 2000-calorie thing it is entirely possible you've lost some muscle...

So should it be closer to 3000? Am I actually going to lose weight with that much calories. Right now, my main goal is to lose weight, and if I keep as much muscle as possible than great, but the weight is more important.

You may have to play around with it a little bit really. I'm going to say that you should play around with it for a few weeks and see what works best. I know I try to eat just above my bmr because my body is so DAMN slow concerning metabolism I can't give it much room for error.
