Whether or not its worth it depends on how many people youre feeding. When I had 4 kids in the house, we'd go through a beef per year. Now that Im older, my wife and I dont eat as much but the 18 yr old twins eat the world. Now, we go through a hog a year and skip the beef. I keep pork shoulder, some chops and put the rest into ground pork which Ive come to prefer over ground beef. Its easier to digest and I can end up with around 300 lbs of meat for around $400 post slaughter. For the money, the hog is better for us and its easier to digest. We make tacos, burgers, meatloaf, enchiladas, soups etc with the ground pork. An entire beef ends up pushing a couple thousand post slaughter and in the current market prolly ends up averaging a cost of $3.50 per lb which is a great price but its gonna be a LOT of meat and unless you have a lot of people in the house, its gonna take you 3 years to eat it. After 2 years, the meat flavor starts losing quality. I can pretty much answer any specific question anyone has about this as it used to be my primary source of income for years.
You could always find someone to go half with you on getting a Steer. We did that one year and it was still extremely cost effective.
