A year of your coffee

Each dot is a day, shaded bag by bag. At 2 cups a day a bag lasts about 7 days, so you'll open about 53 bags.

Paying for quality? Price per kilo is the fair way to compare bags. See how to read a coffee bag label and our roaster directory.

How it works

This calculator turns bag price, bag size, and dose into cost per cup, per day, and per year so you can compare home brewing against cafe spend with real numbers.

  • Compare specialty, supermarket, and bulk coffee on equal terms.
  • See how a small dose change affects monthly spend.
  • Estimate whether upgrading beans still saves money over cafe drinks.

  1. Enter your bag price and weight

    Use the exact size you buy most often so the cost-per-gram figure stays realistic.

  2. Set your dose and daily cup count

    These two inputs usually have the biggest effect on long-term spending.

  3. Compare against cafe pricing

    Use the savings block to judge whether premium beans still beat your usual takeaway habit.

Questions

What is a normal coffee dose per cup for budgeting?

Most home brews land around 15 to 25 grams, depending on method and cup size. Espresso drinks often use more coffee per serving than filter coffee.

Why is cost per cup more useful than bag price?

Bag price alone hides dose size and pack weight. Cost per cup lets you compare products fairly even when packaging formats differ.

How much does grinding finer or stronger recipes affect cost?

Even a small dose increase repeated every day adds up quickly over a month, which is why recipe strength has a noticeable effect on annual spend.

Can this calculator help compare subscription coffee plans?

Yes. Enter the delivered bag price and size for each plan, then compare the cost per cup rather than only the monthly subscription total.
