About this calculator
Brewing coffee at home is dramatically cheaper than buying it from a café, and this calculator shows exactly how much cheaper by dividing the cost of a bag of beans or ground coffee by the number of cups it yields. If a $15 bag makes 30 cups, each cup costs $0.50 — compared with $4 or more at a coffee shop, that is roughly an eightfold saving. To estimate cups per bag accurately, you need to know your dose and the bag weight. A typical drip or pour-over cup uses about 10–15 grams of coffee, while a single espresso shot uses 7–9 grams and a double 14–18 grams. A standard 340 g (12 oz) bag therefore yields roughly 22–34 drip cups depending on strength. Weigh your dose once with a kitchen scale and divide the bag weight by it to get a precise cups-per-bag figure, then enter it here. The result is the marginal cost of the coffee grounds only; it ignores milk, sugar, syrups, filters, electricity, water, and the amortised cost of your machine or grinder, all of which add a little per cup. Even so, the bean cost dominates the comparison with café pricing, where you are also paying for labour, rent, and convenience. Use this calculator to quantify the savings of brewing at home, to compare a cheap supermarket bag against premium specialty beans on a per-cup basis, or to see how a daily habit adds up over a month or year — a $0.50 cup brewed daily is about $182 a year, versus well over $1,400 for a daily café latte.
How to use
Example 1 — Everyday beans. A $15 bag makes about 30 cups. Enter 15 and 30. Result: $0.50 per cup. Verify: 15 ÷ 30 = 0.50. ✓ A daily cup at this rate costs about $182.50 a year. Example 2 — Premium specialty beans. A $24 bag of single-origin beans yields about 20 stronger cups. Enter 24 and 20. Result: $1.20 per cup. Verify: 24 ÷ 20 = 1.20. ✓ Still far below café prices, and useful for comparing premium beans against a cheaper bag per cup rather than per bag.
Frequently asked questions
How do I figure out how many cups a bag makes?
Divide the bag’s weight by the amount of coffee you use per cup. Weigh your usual dose with a kitchen scale: drip and pour-over typically use 10–15 grams per cup, a single espresso 7–9 grams, and a double shot 14–18 grams. A 340-gram (12 oz) bag at 12 grams per cup yields about 28 cups. If you do not have a scale, a level tablespoon of ground coffee is roughly 5 grams, so a "two tablespoon" cup is about 10 grams. Measuring once gives you a reliable cups-per-bag number to enter, and weighing also improves the consistency of your brew.
Does this include milk, sugar, and electricity?
No — it captures only the cost of the coffee itself. A complete per-cup cost would add milk or cream, sugar or syrups, paper filters, the water and electricity to brew, and a small share of the machine and grinder spread over their lifetime. For black coffee these extras are negligible, but for a milky latte the milk can rival or exceed the bean cost. Even so, the bean cost is the right figure for comparing home brewing against café prices, because the café charges far more than the sum of all these inputs. If you want a fully loaded cost, add the per-cup share of milk and consumables separately.
How much can I save brewing at home versus a café?
A great deal. If a home cup costs $0.50 and a café drink costs $4–5, you save roughly $3.50–4.50 every cup. For a daily habit that is over $1,200 a year in savings, even after accounting for milk and the occasional new bag of beans. The gap is so large because café prices reflect labour, rent, equipment, and convenience, not just the coffee. This calculator lets you put a concrete number on that gap and is a popular tool for anyone trying to trim discretionary spending — the daily coffee is one of the most-cited "small luxuries" in personal-finance advice precisely because it compounds.
What mistakes do people make estimating coffee cost per cup?
The most common is guessing cups-per-bag instead of measuring, which can be off by 50% or more depending on how strong you brew. Another is comparing a weak home cup against a strong café drink, or vice versa, without matching the dose. People also forget that espresso uses less coffee per shot than drip, so an espresso bag stretches further. For milky drinks, ignoring the cost of milk understates the real per-cup cost significantly. Finally, comparing a premium bag’s per-bag price against a cheap bag’s is misleading — the per-cup figure this tool produces is the fair comparison.
When is this calculator not the right tool?
It is designed for home brewing where you buy beans or grounds by the bag. It is not suited to estimating café or office coffee costs, single-serve pod systems (where you should divide the pack price by the number of pods), or ready-to-drink bottled coffee. If you want to compare brewing methods that use very different doses — espresso versus French press, for example — calculate each separately using its own grams-per-cup. And if your goal is a complete budget rather than a bean-cost comparison, you will need to add milk, consumables, and equipment costs, which this simple division does not include.
