Seven lines of arithmetic
Change any assumption you disagree with; the answer follows.
| Estimate actual drinkers | 50 guests × 75% drinking rate | 38 drinkers |
| Calculate base consumption | 38 drinkers × 1.5 drinks/hour × 4 hours | 228 base drinks |
| Apply consumption decay | Adjusted for drinking slowdown over time (decay factor: 3.25) | 185 adjusted drinks |
| Apply Halloween party modifier | × 1.3 (+30% for spirits) | 238 spirits servings if served alone |
| Share of the bar | 238 servings × 43.5% | 104 spirits servings |
| Convert to bottles | 104 servings ÷ 17 servings per bottle | 6.1 bottles (raw) |
| Add 15% buffer & round up | 6.1 × 1.15 = 7.0, rounded up | 8 bottles |
The Knot's wedding guide plans one drink per guest per hour with a 50/25/25 liquor, beer and wine split. This model counts only the guests who drink, slows the pace after the first hour, and keeps a 15 percent margin; read the methodology.
