Ice Calculator — How Much Ice for a Party or Cooler
~30 seconds
Enter your headcount, event duration in hours, and how the ice will be used (drinks/cooler or buffet/food transport). The calculator estimates pounds of ice from catering per-person-per-hour ranges and rounds to common bag sizes (7, 10, and 20 lb). Scope is event/food-service quantity only — not bar or alcohol planning.
What this calculator determines
It estimates the pounds of ice for an event from a per-person-per-hour rate scaled by duration, then rounds up to common bag sizes.

Examples
25 people, 4 hours, drinks
25 people, 4 hours, drinks/cooler (1 lb/h)
Calculation
- Lbs = 25 × 1 × 4 = 100 lb
- Bags (10 lb) = ceil(100 ÷ 10) = 10
100 lb ice → 10 bags (10 lb each)
Assumptions & Conventions
- Per-person-per-hour is a planning estimate
- The rate is about 1 lb per person per hour for drinks and coolers and 1.5 lb for buffet or food transport — catering planning estimates, not guarantees.
- Bag rounding
- Pounds are rounded up to whole 7, 10, and 20 lb bags, which may leave extra ice.
- Event and food-service scope only
- Scope is event and food-service quantity; it does not cover bar or alcohol planning.
