How we calculate it

Everything is plain arithmetic with the assumptions you pick. No regression, no machine learning, no opinions baked in. The formulas:

Cost per home shot

(beans_price_per_lb / 453.6 g) × grams_per_shot + $0.02 electricity + $0.11 maintenance

We use 453.6 grams per pound. Maintenance is $40 per year amortized across ~365 shots, which works out to roughly $0.11 per shot at typical use. If you pull twice as many shots, per-shot maintenance drops accordingly — the calculator does this for you.

Daily, monthly, yearly savings

(cafe_price − home_shot_cost) × shots_per_day is your daily savings. We multiply by 30.44 for monthly and 365.25 for yearly to handle leap years and partial months.

Payback period

(machine_price + grinder_price) / monthly_savings, expressed in months, then formatted as "X years Y months" when greater than a year.

Net savings over N years

(yearly_savings × N) − (machine_price + grinder_price). Negative values mean you haven't broken even yet within your projection window.

Frequently asked questions

Does this include the cost of a grinder?

Yes. Espresso quality is bottlenecked by the grinder, so we include a separate grinder slider (default $200). If you already own a capable grinder, slide that input to $0 to model your real upfront cost.

How is electricity estimated?

We use a flat $0.02 per shot. A typical home espresso machine draws 1200 to 1500 watts, but only for ~30 seconds per shot plus some standby idle. At the U.S. average residential rate of about $0.16 per kWh, that lands in the $0.015 to $0.025 range. We round to two cents and call it good — electricity is not the deciding factor in this math.

What about maintenance, descaler, and replacement parts?

We amortize $40 per year ($3.33 per month) to cover descaler, water filters, group head gaskets, and incidental parts. Heavy daily users may spend more; light users less. Major repairs (boilers, pumps, PCBs) are not modeled and can be significant after year 5.

What does the calculator deliberately not model?

Taste improvement is subjective and not modeled. Equipment depreciation, time investment to learn espresso, the social value of going to a cafe, and the time value of money are also excluded. The result is an upper bound on simple cash savings, not a complete life decision.

Why do my numbers look so different from a friend’s?

The biggest swing factors are (1) cafe drink price in your city, (2) how many shots you actually pull per day on average, and (3) the dose. Two shots a day at $6 each in San Francisco hits payback fast; one shot a day at $4 in a small town takes much longer.
