Event batch & procurement calculator
A four-component, one-recipe planner. Edit the quantities for spirit, citrus, syrup, and soda, then check the batch and purchase plan.
Defaults are a fictional example, not consumption guidance, safety limits, or industry benchmarks. Resetting restores the example.

What this calculator does, and does not do.
It rounds allocated serves up once, scales ingredient milliliters, adds water only to batch-eligible liquid, rounds containers up using usable capacity, and rounds net purchases up after stock. Finishing ingredients are procured but excluded from batch-container volume.
It does not estimate alcohol safety, shelf life, ice, glassware, staff, break coverage, total event demand, or prep labor. Review those separately. Zero guests, zero allocation, or zero planned servings produce a zero-volume plan; package and container capacities must remain positive.
