Job this solves
Find how many cups until home brewing beats café pricing after setup costs.
Formula
Cups to break even = (machine + setup) ÷ (café price − home cost per cup).
Assumptions
Defaults are starting points, not recommendations. Outputs inherit your inputs.
Common questions
Should setup include a grinder?
Yes, if you are buying one for this workflow. Include accessories you would not need at a café.
What if home cost is higher than café?
The math will not show a break-even — the calculator reports that honestly.
