I did a similar switch and made a spreadsheet to model it all out. I lost money in the first year, and ended up saving roughly $500/year every subsequent year.

I did a similar switch and made a spreadsheet to model it all out. I lost money in the first year, and ended up saving roughly $500/year every subsequent year. And that was after buying a $400 grinder and $700 espresso machine and misc. accessories. And also with upping the frequency with which I drank coffee since I'm buying bags of beans now. For those with expensive coffee habits, it is ABSOLUTELY possible to save a bunch of money annually, and drink coffee that is much better and more consistent than many decent cafes once you learn what you're doing, figure out what beans you like, and learn to dial in the grind. I'm now tempted to get into home roasting to save even more since the green beans keep a really long time.
