About this calculator
Party ice planning follows a standard 1-1.5 pounds per guest for drinks, plus extra if you're also chilling beverages in coolers or tubs rather than serving purely by the glass. This calculator scales pound-per-guest ice needs by event length and whether ice is also used for cooler chilling.

FAQ
How much ice do I need for a party?
For 40 guests over a 4-hour party with drinks also chilled in coolers, plan for about 60 pounds of ice total — roughly 40 lb for glasses and 20 lb for cooler chilling.
Why does party length matter for ice?
Longer parties mean more refills per guest and more melting, so a 6-hour event needs noticeably more ice per person than a quick 2-hour gathering even with the same guest count.
How much ice does chilling a cooler take?
Plan roughly 0.5 lb of ice per guest specifically for cooler chilling on top of drink ice, since a well-packed cooler needs a substantial base layer plus ongoing ice to stay cold for hours.
Should I buy bagged ice or make my own?
For anything over about 20-30 lb needed, buying bagged ice is far more practical — most home freezers can't produce and store that volume without days of advance planning.
Accuracy and limitations
