Coffee Cost Per Cup
Calculate the true cost of each cup of home-brewed coffee including beans, water, and filters. Compare to cafe prices and see your yearly savings.
About this calculator
The obvious cost of home-brewed coffee is the beans, but this calculator adds in the two smaller expenses that quietly pad every cup: the water itself, priced from your municipal rate and the roughly 10oz a typical cup uses, and a paper filter where your brew method actually needs one. That filter cost is what actually differs between methods here — pour-over and AeroPress both use disposable paper filters and carry that per-cup cost, while espresso, French press, and cold brew use reusable metal mesh or no filter at all, so switching between these methods changes your cost per cup even if your bean price and dose stay identical. Bean cost itself scales directly with your dose in grams, converted from your entered price per pound using the standard 453.6 grams-per-pound conversion, which is also how cups-per-pound is derived — simply how many of your chosen gram doses fit in one pound of beans, rounded down since a partial dose isn't a full cup.
Monthly and yearly projections assume a steady one cup per day, a simplifying baseline you can mentally scale for your actual daily habit — someone drinking two cups a day should roughly double these figures. The yearly savings comparison uses a flat $5 average café latte price as its benchmark; your actual local café pricing, and whether you're comparing against drip coffee versus a specialty espresso drink, will shift how meaningful that specific savings number is to your own situation.

How to Use This Calculator
- Enter the price per pound of your coffee beans.
- Set grams per cup for your typical dose and select your brew method.
- Enter water cost per gallon and filter cost per use if applicable.
- The calculator shows cost per cup, cups per pound, monthly and yearly cost (at one cup per day), and annual savings versus a $5 café cup.
- Use the results to compare bean brands or methods and optimize your coffee budget.
How the result changes with Bean Price (per lb)
| Bean Price (per lb) | Cost Per Cup |
|---|---|
| $7.50 | $0.35 |
| $11.00 | $0.49 |
| $23.00 | $0.96 |
| $38.00 | $1.56 |
What each input means
- Bean Price (per lb)
- Price per pound of whole bean coffee.
- Grams per Cup
- How many grams of coffee you use per cup. Pour-over typically 15–18g, espresso 18–20g.
- Brew Method
- Method affects filter cost. Espresso & French press need no paper filter.
- Water Cost (per gallon)
- Municipal water cost per gallon. US average is ~$0.005.
- Filter Cost (each)
- Cost of a single paper filter, if applicable.

Frequently Asked Questions
Why does brew method change the cost per cup if I'm using the same beans and dose?
Brew method determines whether your cup needs a disposable paper filter — pour-over and AeroPress both use one, adding a small per-cup cost, while espresso, French press, and cold brew rely on reusable metal filters or no filter at all. Since bean cost and water cost stay the same regardless of method, that filter cost difference is the entire reason switching brewing methods changes the total cost per cup in this calculator.
How is 'Cups Per Pound' calculated, and why does it round down?
It divides a pound of beans (453.6 grams) by your chosen grams-per-cup dose to see how many full doses that pound contains, then rounds down because a partial dose left at the bottom of the bag isn't enough to brew another complete cup at your usual strength. A higher grams-per-cup dose (a stronger brew) naturally reduces how many cups you get from the same bag of beans.
Why does water cost so little compared to beans in the cost breakdown?
Municipal water is genuinely inexpensive on a per-cup basis — at a typical US rate of about half a cent per gallon and roughly 10 ounces per cup, water usually contributes a small fraction of a cent to each cup's total cost. Beans dominate the total because coffee beans cost dollars per pound while water costs fractions of a cent per gallon, so even a modest bean price swamps the water cost by comparison.
Does the $5 café comparison account for my actual local coffee shop prices?
No — it uses a flat, generic average café latte price as a reference point rather than pulling in your specific local pricing, so if your regular café charges notably more or less, or if you typically order plain drip coffee rather than a latte, your real-world savings will differ from this figure. Treat the yearly savings number as a useful ballpark for the home-brewing-versus-café tradeoff rather than a precise calculation of your own spending habits.
