Why ice runs out faster than people expect
Ice serves double duty at most parties — chilling drinks in coolers and filling individual glasses — so the effective consumption rate per person is usually higher than people plan for, especially on a warm day. This uses the same rate-based shape as the party drinks calculator (guests × hours × a per-person rate) so you can tune it up or down for your specific event, then rounds up to whole bags since that's how ice is actually sold.
Frequently asked questions
How much ice per guest does this assume?
A common event-planning estimate is roughly 1-1.5 lbs of ice per guest per hour, covering both drinks and any ice used for chilling — hot weather or an outdoor event generally pushes toward the higher end.
