Think you’re saving a small fortune making coffee at home? Do the math.

We previously wrote of our annoyance with the old and ever-popular yarn spun by wannabe personal finance gurus who constantly tell us we can become millionaires by quitting our daily coffee habit — or by replacing it with home-brewed coffee. For the record, we have a lot of coffee both out (as evidenced by CoffeeRatings.com) and in the home. But we’ve always thought that home-brewed coffee is hardly the magic path to champagne wishes and caviar dreams. This time we do a little of the math to show why.
Many of these personal finance hacks first fail to recognize that coffee, for at least some people, is one of life’s small pleasures. The idea of giving it up entirely makes about as much sense as giving up other “superfluous” things in life — such as haircuts, your child’s dance lessons, and cable TV. Once you get past that logic, the debate then becomes about the private jets you’ll be able to afford by making your own coffee or espresso at home instead of paying Starbucks each time for the mythical $32 coffee beverage. (Hey … inflation. OK, so we’re exaggerating about the $32 beverage to make a point. But then again, so are they.)
We recently came across a blog post, similar to the thousands of others just like it, where a “home savings tip” savant posted on how she saved a “small fortune” by switching from her thrice-weekly Starbucks habit to a stove top Bialetti coffee maker at home.
Let’s do the math
Small fortune, eh? Let’s do the math. A $4 bucket of Starbucks’ pumpkin-pie-flavored Cool Whip, purchased three times a week, will set our home-savings-tip heroine back about $12 a week — or about $600 a year.
A new Bialetti will set her back about $20 — which is nice and cheap compared to some of these ridiculous $1,200 hulking piles of home espresso machine plastic that typically produce shots inferior to even Starbucks’ dubious standards (Jura, anyone?). Then add a chop grinder for about $30, and her capital outlay comes out to be about $50.
Now since fresh roasted coffee is like fresh baked bread, the supply needs replenishing every couple of weeks before it goes stale. So if she’s buying Starbucks’ coffee (and it is pretty much already stale when you buy it), that should set her back about $6 for a half pound. Then add some incidental charges for milk, pumpkin pie flavoring, and tubs of Cool Whip — but for the sake of argument, we will consider it negligible (which it isn’t).
That comes to about a $50 capital outlay plus $6 every two weeks = about $200 in the first year.
Labor costs: because your time isn’t free
Now let’s factor in labor costs. Starbucks’ costs are dominated by labor, not coffee. To say that your labor comes out in the wash is deceiving yourself: your time is money. The federal minimum wage is $5.85 per hour (in SF, it is $9.36) — and let’s say her time is only as valuable as the lowest fry cook at McDonald’s at $6 an hour. And let’s say that making these coffee drinks at home takes about 15 minutes of her time — between grinding, watching the stove, steaming milk, washing dishes, cleaning the espresso machine, etc. All the work that Starbucks pays someone else to do for you. Three times a week for a year comes to about 40 hours of labor a year = $240.
So in her first year, you compare her $600 Starbucks habit to $200 + $240 = $440. So she saved maybe a whopping $160 in the first year — minus her additional expenses for milk, pumpkin pie flavoring, and Cool Whip. And her coffee wasn’t probably nearly as good as the kind and variety she had buying out: the coffee supplies were probably more stale, the consistency wasn’t right, and she was using equipment and skills that were a fraction of what the pros have. (After all, a moka pot doesn’t even technically make espresso to begin with.)
Add that she had to put up with this inferior coffee for a whole year. Then add that she just valued her own time at the lowly wages of a fry cook working a burger joint fronted by a clown.
A small fortune? Indeed.
But what if you buy a $1,200 home espresso machine?
But at least she didn’t buy some $1,200 Jura (likely without a decent grinder, we might add) that will require her to grin and bear hundreds of inferior espresso shots before she breaks even on the purchase price alone. Or worse…
Home espresso machines, for most buyers today, are the home exercise treadmills of the previous decade. She could easily tire of the inferior shot quality she gets at home, and she could tire even more of doing all the labor herself. After all, we live in a society that can’t even be bothered to slice an apple or toss a salad because it’s too much effort. This means that not only does she return to her regular Starbucks habit, but she does so with an additional $1,200 hole burned into her pocket — now that her home espresso machine is gathering dust in the kitchen corner.
This is why we generally recommend a home espresso setup for less than five percent of the people who ask about one. Unless you’re in it for the pursuit of higher quality shots, you’re going to be gravely disappointed. Don’t even think that you’re going to save much money with a home espresso setup unless you can make the time commitment — and if your taste buds can’t tell the difference in quality.
Sipping a double espresso at Blue Bottle Cafe earlier this afternoon, I felt like a million bucks. In fact, that espresso shot of single origin, dry-processed, Ethiopian Sidamo was so good, it deserved its own post. (To be continued…)

Including labor costs is just silly. Most people can’t simply choose to do slightly more work to pay for coffee in the way that they can choose to make coffee every morning. However, even if they could this wouldn’t be a legitimate argument since for many people it will take them the same 15 minutes to go to Starbucks and get coffee. Perhaps you should also add that $240 to the $600 figure?

Most people devalue their own time at a ridiculous level. I know people who have struggled for two hours getting their oil filter off, their oil pan drained, and replacing it all just to save the $10 (once you subtract the cost of replacement parts) versus having their oil changed down the street.
When you spend $4 on a bucket of Starbucks’ pumpkin-pie-flavored Cool Whip, you’re mostly spending money to cover Starbucks’ labor costs. People whine and lament that Starbucks is ripping people off because you can get a cup of coffee for a mere $1 down at the diner — but the diner need only have an untrained monkey take 3 seconds to dump a Bunn warmer coffee pot into a styrofoam cup: there’s no timing for an espresso shot, no preparation of milk frothing, no pumpkin pie and Cool Whip mashing. The big difference is labor, but nobody seems to recognize that. All coffee is just “coffee”, right? Wrong.
You’re fooling yourself if you think your time is free and therefore worthless. Any 15 minutes you spend making your own bucket of pumpkin-pie-flavored Cool Whip is 15 minutes you’re not answering customer service calls working for The Man, 15 minutes you’re not making millions off online stock trades, or 15 minutes you’re not writing that hockey-stick growth business plan for your new start-up. The economics of making coffee at home versus having it out is a primarily question of labor costs, not materials. Analyzing it any other way is a false premise.
For the people who drive special to get coffee, it’s not like they were probably going to play shut-in for the day. Or that their steady home supply of coffee, milk, pumpkin pie flavoring, and Cool Whip comes out of the tap. Of course, where I work, a Peet’s is just down the stairs…

In my wayward youth I was a manager for Starbucks Coffee Co. Over my tenure I sold thousands of dollars worth of at-home brewing and espresso gear. The novelty of at-home coffee and espresso wore off within months (if not weeks) and time after time those customers were back in our line… every morning.

At some point you recommended thinking about this in an email to me and it was 100% right. Small World espresso isn’t perfect, but it costs less than $2 and I don’t have to do any cleanup. I can also french press good beans at home in under 10 minutes and without the four-figure investment in a grinder and espresso machine that wouldn’t fit on my counter.
That said, if I had a couple K floating around, I’d probably go for a home setup.

Just came up on this website and came up on this post. I’m a coffee lover and really into personal finance.I agree that we need to consider personal enjoyment and convenience as part of the coffee experience and it’s hard to judge that against dollar and cents.
However, from a personal finance point of view, that “small pleasures” costs can add up, especially for those who can rationalize the cost and want things now and are unable to save long-term. Also, who has coffee 3 times a week? It’s more like 3 times a day!
Plus, you should consider that the $600 is money spend after taxes. You’d need to work say $850 unless you could somehow write those off as business expenses.
You should also not consider factoring your working hourly wage when making it at home unless you would have used that time to be working and making money as opportunity costs. Chances are at home, you’d be reading a newspaper or checking your email. Might as well take some personal enjoyment in making your own espresso … perhaps by saving that $400 (more if saved in a tax deductible investment) a person could open their own small cafe when they are financially free to do anything they want.

Thanks, 5.JM. While I understand your points, I don’t agree with them at all for the same reason I don’t churn my own butter to save a few bucks. “Free time” is a myth.
Not to mention that I don’t buy into the deconstructed, non-integrated, superpositional microeconomic thinking upon which these hypothetical debates rest. If you applied the same principles to weight loss in isolation, they would suggest that we should be a nation of emaciated supermodels instead of tragically obese ever since the public wholly embraced diet soft drinks 20 years ago.
