Your party coffee service plan
Use the amount of finished coffee your machine actually supplies, the coffee pour in your own mug and a complete brew-and-reset cycle. This two-wave model uses one machine, full batches and reusable holding vessels. Initial pours happen at arrival; all assumed refills happen at one chosen minute. It checks a proposed allocation, rather than predicting how much guests will drink or verifying holding temperature.
People and equipment
Choose first. Changing unit asks before clearing the three volume fields. Counts, percentages, minutes and grams stay. A machine's “cup” is not a measurement unit here.
Drinkers: 0–500. One initial pour each. Refills: 0–5 each; 0.5 means one refill for half the group. The combined refill count is rounded up.
Choose 0–100%. Reserve pours are rounded up separately and are not counted as expected drinking. With refills, reserve is ready at the refill wave; without refills, it is ready at arrival.
Measure below the mug rim, leaving the space you want for milk. Use coffee volume, not the vessel's brim capacity.
Measure finished usable coffee from your own brew recipe. Water put into a reservoir and a machine's cup count are not substitutes.
Count only vessels you can use together for this coffee. Do not count a carafe that must be emptied before the next brew. Full batch output must fit; this model does not silently discard excess coffee.
Include filling, brewing, transferring and any required reset in each 0.1–120 minute cycle. Preparation time: 0–1,440 minutes.
Both: 0–1,440 minutes. The refill minute must fall within service. A refill at minute 0 can use initial batch excess only; the model cannot run a second brew before that deadline.
Use your own machine instructions and preferred recipe, 0–1,000 g. Enter 0 to omit a coffee purchasing estimate. This planner does not recommend brew strength or calculate reservoir water.
Enter your measured pour, yield, capacity and timings.

Shopping and setup
Count mugs by people and your chosen spares, not by the number of refills when mugs are reused. Check your recipe's input water, filter needs, milk preferences and chilled milk quantities separately. Follow the equipment's operating and holding instructions; elapsed time here is not a temperature check.
Use the allocation with your equipment
- Count actual coffee drinkers, including hosts. Keep water and your agreed alternatives available. Set refill and reserve assumptions for this gathering.
- Measure a comfortable coffee pour, the usable finished yield of one batch and the usable holding vessels. Run your own full fill–brew–transfer–reset rehearsal and time it; no physical test is supplied by this tool.
- Enter all liquid measurements in one unit. One machine brews sequentially. Full-batch excess from the initial wave is carried into the refill allocation; the same coffee is not counted twice.
- Read every shortfall. If time or holding space is insufficient, the tool gives no feasible brew timetable. Change the equipment plan or service assumptions and calculate again. It does not schedule multiple machines, individual guest arrival times or partial batches.
- Save a project before closing. There is no automatic saved copy. Importing into populated entries asks before replacement. Editing makes prior CSV and print results stale.
- For print, choose matching A4 or US Letter, portrait, 100% scale, no margins and no browser headers or footers. Check the preview. A failed allocation can be printed as a review sheet, clearly marked with its shortfalls.
