What to do with the number
Consumption varies widely by crowd, event timing, weather, transportation and availability of nonalcoholic options. Always provide plenty of water and nonalcoholic choices; this calculator is inventory planning, not a drinking target.
Planning estimate
Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
