Depends.
If you want artisanal bread? No.
If you mainly buy the cheapest white sandwich bread you can find? No
If you eat a fair amount of bread? Potentially. At least two loaves a week.
If you got a family that can knock out a loaf every other day? Absolutely.
Bread machines do a good job of making basic bitch bread to raisin bread, pumpkin bread, and herb infused bread. They are also handy for starting dough like pizza dough and such by taking care of the multiple kneading sessions.
Just for making bread, you aren't saving money if you buy the typical $1.50 loaf at Walmart once a week because the initial cost is well over a year worth of bread. The raw ingredient cost is going to be close to a dollar a loaf for a 2 pound bread machine. Factoring in the increased power demand, clean up, etc? You don't save anything really.
What you do get is much better tasting bread without a bunch of additional ingredients. I got one and I use that bitch a lot, but if I want fancier shit, even only a step up like a baguette? I gotta use the oven anyway. 99 times out of 100, I am just having basic bread for filler or sandwiches though and go through about four loaves a week, so it was a damn good purchase for me.
