If you're making plain regular bread, the cost isn't going to be less. It mostly evens out, or maybe a little more expensive. The benefits, though, are plenty.
You get to smell that fresh bread all through the house. Yes, of course, that's a benefit. Try it. You'll see. Who needs soy wax cubes when you've got bread baking?
You don't have the preservatives and you can make little additions, if you want.
Since I'm a kid, though, I still like my plain white bread. Sometimes, a peanut butter and jelly sandwich is the best comfort food there is.
For those times, I need my White Sandwich bread recipe. The bread is sturdy enough to make slicing easy and it will hold up to jelly, peanut butter or even chicken salad.
