The calculator divides the bag price by the bag weight to get the cost per gram of coffee, then multiplies by your dose in grams to get the bean cost per cup. It adds milk cost (ml divided by 1000 times milk price per liter) and extras like sugar, filters or paper cups. Cups per bag is bag weight divided by dose. Monthly home cost is cost per cup times cups per day times 30, yearly is times 365, and the home vs cafe comparison uses the cafe price you entered for the same daily habit. Results are planning estimates, not professional advice.
Everything starts with the bag. Divide the bag price by the bag weight in grams and you get your cost per gram of coffee. Multiply that by your dose per cup and you have the bean cost per cup, the single biggest number in this whole calculation.
Worked example: a $17 bag holding 320 g of beans costs about $0.053 per gram. At a 16 g dose per cup, the beans cost $0.85 per cup, and the bag makes exactly 20 cups. Two cups a day puts the home cost at $51 a month and $620.50 a year. The same two cups from a $5 cafe cost $3,650 a year, so the yearly savings come out at $3,029.50.
The formula also adds milk and extras honestly. Milk cost is the ml per cup divided by 1000 times the milk price per liter, so a milky drink shows its real cost. Extras cover sugar, paper filters and takeaway cups if you use them. Cost per month is cost per cup times cups per day times 30, and cost per year uses 365. A full kilo of beans (1000 g) at a 16 g dose makes about 62 coffees, and honest coffee consumption cost comparisons across brew styles must use your real dose, not the bag's serving claim. Many thin calculators stop at dividing bag price by claimed servings; that hides the dose, which is the variable that moves the result most.
Start with your currency, then enter the coffee bag price and the bag weight in grams (a standard 12 oz bag is 340 g, and many specialty bags are 250 g or 320 g). Next enter your coffee dose per cup in grams: a typical drip or pour-over uses 14 to 16 g, an AeroPress about 14 g, and an espresso double shot 18 to 20 g. If you brew stronger, enter the bigger number and watch the cost move.
Then add milk per cup in ml and the milk price per liter, plus any extras per cup (sugar, filters, paper cups). Enter your cups per day and the cafe price per cup you normally pay, and you will instantly see your cost per cup, cups per bag, home cost per month and per year, and the cafe cost per year for the same habit. The page is mobile-first: full-width tap targets and 16px inputs so nothing zooms or scrolls sideways on a phone. Run your usual recipe, then run your dream recipe and compare.
Home coffee costs roughly $0.50 to $1.25 a cup depending on your beans and dose, while a cafe cup runs $3 to $6 or more. That gap is small per cup and enormous per year: two $5 cafe coffees a day cost $3,650 a year, while two home-brewed cups a day typically cost $400 to $900. Even one $5 coffee five days a week comes to $1,300 a year, which is why the finance idea called the latte factor caught on: small daily spending, repeated for years, becomes serious money.
You do not need to quit cafes entirely. A partial switch often saves most of the money with none of the sacrifice: replacing three of five weekly $4.50 purchases with $0.75 homemade cups saves about $585 a year. Use the calculator with your real cups per day and your real cafe price, not an average from the internet, because your habit is the only one that matters. For context, the average person who visits a coffee shop regularly is reported to spend roughly $1,100 to $2,200 a year on coffee, which is exactly the spending this coffee spend calculator helps you shrink. The home barista brewing two cups a day spends a fraction of that, which is why the coffee shop vs home coffee cost question has such a clear answer. Remember tips, pastries and delivery fees quietly inflate cafe spending beyond the menu price, and home coffee costs are estimates for budgeting, not professional advice.
Brew style changes the cost per cup more than the brand does. Drip with pre-ground coffee is the cheapest style: roughly $0.40 a cup with the bag's price spread over a long life. Fresh-ground drip runs about $0.45. Coffee pods (K-Cups and capsules) cost roughly $0.85 to $1.05 per cup because the pods hold only 10 to 12 g of coffee and you pay about double per gram for the convenience, which adds up to over $1,500 more than drip over five years for one cup a day.
Espresso drinks at home sit in the middle: the bean cost is higher because a double shot uses 18 to 20 g, and milk drinks add milk by the ml, but a home latte still lands around $0.50 to $1.00 once equipment is amortized. That is why the calculator includes milk per cup in ml and extras: a black pour-over and a milky flat white made from the same bag have very different true costs. If pods are your thing, run the numbers with a 10 g dose and a $0.90 effective bag price per pod equivalent, then compare honestly against drip.
First, respect the dose. Moving from a 15 g dose to a 19 g dose raises the bean cost per cup by about 27% on the same beans, so brew by weight with a cheap kitchen scale instead of eyeballing scoops. That alone is the biggest saving most home brewers ever find.
Second, think about the bag, not the cup. A larger bag is usually cheaper per gram, and whole-bean coffee you grind yourself typically costs less per gram than pre-ground of the same quality while tasting fresher. Third, decide whether to count the coffee maker in the cost: a $350 setup amortized over three years at two cups a day adds about $0.16 per cup, so it matters for expensive machines and barely matters for a $25 French press. Finally, waste less: a small waste percentage on milk and grounds is realistic, so the calculator lets you add extras per cup and account for it instead of pretending every gram lands in the mug.
A 12 oz bag is 340 g. Divide by your dose per cup: at 16 g per cup it makes about 21 cups (340 divided by 16), at 15 g about 22 to 23 cups, and at 20 g about 17 cups. Stronger brews empty the bag faster, which is why dose is the variable that matters most for cost per cup.
Standard doses run about 14 g for drip and pour-over, 14 g for AeroPress, 16 g for a big pour-over, and 18 to 20 g for an espresso double shot. Brewing around a 1:15 to 1:16 coffee to water ratio is a common starting point, then adjust to taste.
Yes, roughly double per gram. Pods hold only 10 to 12 g of coffee and cost about $0.85 to $1.05 per cup, while drip coffee from a bag costs roughly $0.40 to $0.45 per cup. At one cup a day, pods can cost over $1,500 more than drip over five years.
Yes, for almost everyone. Home coffee costs roughly $0.50 to $1.25 per cup depending on beans and dose, versus $3 to $6 at a cafe. Two $5 cafe coffees a day cost $3,650 a year; two home cups a day typically cost $400 to $900, so the yearly savings are in the thousands.
About $1,300 a year (5 dollars times 5 days times 52 weeks). That is the classic latte factor example: small daily spending, repeated weekly, becomes serious money over the years.
The latte factor is the idea that small, repeated spending (like a daily latte) adds up to large lifetime totals. For example, $5 a day invested at a 7% return for 30 years would grow to roughly $180,000, which shows how daily habits compound. It is a budgeting illustration, not professional investment advice.
Usually a little, and it tastes fresher. Whole-bean coffee typically costs less per gram than pre-ground of comparable quality, and you avoid paying for convenience grinding. The bigger saving comes from weighing your dose instead of eyeballing scoops, which keeps your cost per cup consistent.
Only if it is expensive relative to your habit. A $350 setup amortized over three years at two cups a day adds about $0.16 per cup, while a $25 French press adds almost nothing. Most people leave cheap gear out of the per-cup math and include it mentally for expensive espresso machines.
Multiply price per cup by cups per day by buying days per week by 52. For home coffee, use the calculator above: it divides your bag price by bag weight to get cost per gram, multiplies by dose, adds milk and extras, then multiplies by cups per day and 365. Both are estimates for budgeting.
