One example is bread. I was baking bread the other day, and obviously the cost of the ingredients I put in the loaf are less than the cost of buying a loaf at the supermarket, but that doesn’t include the cost of putting the oven on.
Or dry beans vs canned beans; does the cost of boiling the beans actually bring the cost up to be equivalent to canned beans?
I know that everyone’s energy costs are different so it’s not possible for someone to do the calculations for you, but I’ve never bothered to do them for my own case because bills I get from the energy company just tell me how much I owe them for the month, not “you put the oven on for 30 minutes on the 17th of June and that cost you X”. It sounds like a headache to try calculate how much I pay for energy per meal. But if someone else has done that calculation for themselves I’d be interested to read it and see how it works out. My intuition is that, in general, it’s cheaper to make things yourself (e.g. bread or beans like above), but I couldn’t say that for sure without calculating, which as I said seems like it would be a pain in the ass.
My homemade sourdough costs more than store bread, but not more than fancy sourdough bakery bread. I can’t buy flour wholesale, don’t make that much bread. But when it’s good it’s better than any bakery bread I’ve had. So, better, probably not cheaper.
Home cooked meals vs. restaurants does save money.
Gardening - most things work out cheaper than buying, though as I am a salaried worker I am not allocating labor cost.
If it were to be compared to doing 1.5x pay overtime, then working more would make more money than we could save by doing cooking and gardening, it would always work out better to spend that time at work. But then the health impact of doing all that work and always eating out would have to be factored in.
You also have to factor in the cost of your time. If it takes longer with one or the other that needs consideration too.
Yeah, that’s a factor that is fairly easy to calculate though. And for myself, I’m happy to spend more time within reason. I cook fairly high-effort meals if I think the effort (and time) will pay off. I was mostly asking about energy costs as that’s something I feel is quite hard to quantify properly. With time you know exactly how long it takes and can ask yourself whether or not it’s worth it for you.
I think, but cannot be certain, that is includes some energy cost.
It really is excellent.
DIY bread is a real winner. Costs me about $1.05 to make a 1-lb loaf. That includes flour, yeast, salt, and gas to run the oven. An equivalent quality loaf of Safeway bakery bread costs anywhere from 3 to 6x that much. And it’s like 10-12 minutes of actual effort, including cleanup. I also make hoagy-style sandwich loaves, soft dinner rolls and other things. Same basic recipe, just a few minutes more effort to handle the dough differently. I’m totally addicted to fresh bread.
I don’t have a calculation to back it up, but I’m inclined to believe store bought will always have a cheaper production cost. Your can of beans wasn’t made by one person per one can of beans at a time. It is done in a factory producing millions of cans. That kind of industrial process will always be cheaper. It’s designed to be that way. Beans can be bought wholesale below the cost available to you. And with that operation at scale it will undoubtedly be more energy efficient per can of beans. The consumer cost is something else. You will save money buying the raw ingredients and making your own beans rather than buying canned.
I did the math a little bit ago because I was baking a lot of bread, and I think depending on the bread it was actually cheaper to buy the same kind of loaf baked in my grocery store than to buy the equivalent ingredients. This was a Publix though which at least in my area are on the more expensive end and they didn’t have store brand bread flour so I had to go with a fancy brand.
I tried with muffins. I have been really into muffins, but it was $7 for a 4 pack. So I bought some mix, eggs, oil, etc., and made my own. I think it came out to a little less than $2 per muffin, which is pretty similar to the original, not to mention I don’t have any dishes.
I’ve been making bread regularly for years. A 1-lb loaf costs me about 90 cents USD for ingredients and 15 cents to run the oven. “Nice” Safeway bakery loaves that roughly correspond to what I make cost anywhere from $3-$6, and the whole process takes me 10-15 minutes of actual effort (including cleanup). I don’t count rising and baking times because I’m doing other stuff.
Having also consumed a lot of packaged food (I’m not a crusader against it) I would say cooking meals from store-bought ingredients costs around half as much. Home-growing vegetables adds a huge amount more work. I did a garden for 2 years, many years ago - it was more of a fun project. On the scale I did it I never felt the hours of labor paid off dollar-wise. And what with mulch and other things gardening is something you can pretty much spend as much money on as you want lol.
Fun fact: if you go to the deli counter and get them to slice meat for you it’s about half the price of the store-brand deli packs on the shelves, which are the exact same meats, sliced and packaged by the same people. The only difference is you stand there waiting for a minute while they do it instead just grabbing it off the shelf. The high price of even marginal convenience.
How? Flour here is up to about $7 for a 5lb bag (2.2kg) and I make 2 loaves with 1kg flour, I’m at $1.50 per loaf flour only, not counting the flour that went into the starter, or electricity or time, or other ingredients (brioche uses eggs & milk, pan de mie lots of butter, sandwich bread I usually use whole wheat and some oats and milk, a little butter or olive oil, focaccia lots of olive oil, stuff like that) . I don’t even use packaged yeast and figure my cost is likely $3-4 per loaf.
Flour I buy from Costco costs 90 cents/lb, salt and yeast for one loaf are less than a nickel, and gas to run the oven (including preheat time) is like 15 cents where I live. So maybe $1.15-1.20 per loaf. I’m talking about the basic loaf of bread I make all the time. Brioche etc. will be more, and you can get as fancy as you want, but those items correspondingly cost more from a bakery too. Doing a little of the actual math, eggs are abnormally expensive right now but say $1 each, a cup and a half of milk from Safeway would add another $.65, so call it $2.80 per loaf for fancy bread that would cost 2x-3x that much already made.
No, but I do try to keep prep and cleanup times to under 1 hour for breakfast and lunch combined and 1 hour for dinner.
Or dry beans vs canned beans; does the cost of boiling the beans actually bring the cost up to be equivalent to canned beans?
Nowhere near, at least in a a pressure cooker. An electric pressure cooker uses 1KW when the heater is running, and you cook the beans for about 35 minutes. The heater doesn’t run the whole time but even if it did, that’s around 0.6 KWH at most. And you would normally do a bigger batch than you’d get in 1 can of beans. I have been wanting to measure the actual power usage sometime.
I don’t have a pressure cooker and cook beans on an electric stove, but I imagine it’s similar
On a stovetop you have to soak the beans overnight and then cook them for at least an hour, so energy usage might be higher, idk. OTOH the batch size compensates for a lot.
In Poland there are small bistros that follow a tradition of communist “milk bars”. Some of them even deliver in a subscription model. This totally makes sense financially if it’s for just one person. You can eat there for really nice prices.
Other than that, when it’s for a family of even 2, it never makes sense financially to get food delivered.
Ready to heat food is another topic. Those can also be very competitive in terms of costs and they can be really healthy as in EU it’s forbidden to do any preservatives in that kind of food (frozen or pasteurized).
Nice to hear that about Poland. In the US people love to have DoorDash deliver them fast food at double the price so they can spend more time consuming entertainment.
On the dry beans vs canned beans issue, I am firmly in the “it depends” camp. If you don’t plan your meals ahead of time, then dry beans become difficult to cook as you need to soak them overnight and take much longer to cook. The price of dry beans can be significantly cheaper, but strangely, not so much at a normal grocery store. I found that buying dried beans in bulk or in large bags is wildly cheaper, but most standard grocery stores (in the US) don’t offer them like that so your savings are minimal and don’t justify the the extra prep to me.
I’m a cook as a hobby, so typically the cost of making vs buying does not figure into my decision, except when things at the store get absurdly expensive.
A case in point: Toasted Sliced Salted Salad Almonds from Fresh Gourmet
My wife and I love these on our dinner salads so we go through a lot of them. The cost of a package of these salad almonds has risen to $7 for a 3.5oz (99g)package.
I can buy a 16oz (454g) package of raw almonds for almost the same amount of money, as the 3.5oz (99g) Fresh Gourmet package. I have an electric oven that consumes around 5kwh that runs for roughly 30 minutes during preparation and my daytime electric rate is around $0.13/kwh (I think).
Out of that I get a full pound (16oz, 454g) of salted almonds for ~$7.07 and 30 minutes of my time. I also use about $0.02 worth of salt, bringing the total cost to ~$7.09 for 4.5 times more almonds.
I also can adjust the amount of salt on them as well, as typically my wife and I like less salt that most people.
It’s also fun to do.
Always go homemade if you can. As much as possible. Premade shit is doo-doo for your body.
