On the scale that I do cattle, it would be (I think) impossible to actually make money if I had to count paying for the land. However, as mentioned above, the land is paid for, so I don't worry about that. Now the other question could be: Could I make more money doing something else with the land? Honestly, I don't know. I know that a large professional farmer is row cropping land adjacent to my property on a couple of sides and I'm sure I could arrange to have him do our land as well, and make some money for doing nothing.
On the other hand, the reason we have cattle is mostly because I like cattle and I like my kids growing up around cattle. There are fewer and fewer small farms in our area and most of my kids friends that come over have never touched a cow. As mentioned in other posts, most of my cows are borderline pets - on any given day, I can walk up and pet practically all of the cows and some of the stupid calves (once they've gotten a little age on them). My cattle are pretty low maintenance. My driveway runs through the fields that I rotate them through, so even on days when I don't specifically go look at them and mess with them, I still see them.
Also, we never slaughter any of our cattle - we are not much of a beef-eating family. We probably only eat beef a couple of times per month, and when we do it is almost always hamburgers, tacos, sloppy joes, stuff like that. If we slaughtered a calf, we'd end up with 600 lbs of ground beef! We do it chicken quite a bit, but I've never been successful raising chickens. I've tried it a couple of times and found it to be much more difficult to do than cattle.
Good luck and take care.
