Coffee Cost per Cup Calculator
Turn your bag price, bag weight and chosen dose into transparent per-dose arithmetic. The currency is yours; the tool never assumes a market price.
Your bag and recipe
What it calculates
Usable doses equal bag weight divided by dry dose. Cost per dose equals the bag price divided by usable doses. Enter shipping, milk or other costs elsewhere if they matter to your own budget.
Limit
This is a budgeting aid, not a product comparison or a claim about value. It uses only the numbers you enter in your browser.
How to use it
- Enter the amount you paid for the bag and the bag weight in the same currency and mass units shown on the page.
- Enter the dose you plan to use for one brew.
- Read the cost per gram and the calculated dose cost.
- Change the dose or bag size to compare your own purchase options on the same basis.
When this helps
Use the calculator to budget a home coffee routine, compare the direct cost of two bag sizes, or see how a recipe dose changes the cost of one brew. It reports arithmetic only; a lower cost does not mean a coffee is better value for every drinker.
Frequently asked questions

No. The arithmetic assumes every gram in the bag is available for brewing. Add your expected loss to the bag price or reduce the usable weight if you need a planning estimate.
