Formula Used in Party Drink Calculator
This tool uses a simple but effective mathematical approach.
1. Total Drinks Needed
Total Drinks = Guests × Drinks Per Person
2. Total Liquid Required (ml)
Total ml = Total Drinks × Drink Size (ml)
3. Bottles Needed
Bottles = Total ml ÷ Bottle Size (rounded up)
👉 We always round up because you cannot buy partial bottles.
4. Total Cost
Total Cost = Bottles × Bottle Price
5. Cost Per Guest
Cost Per Guest = Total Cost ÷ Guests
Example Calculation
Let’s understand it with a real-life example:
- Guests = 40
- Drinks per person = 4
- Drink size = 150 ml
- Bottle size = 750 ml
- Bottle price = $12
Step 1: Total Drinks
40 × 4 = 160 drinks
Step 2: Total Volume Needed
160 × 150 = 24,000 ml
Step 3: Bottles Needed
24,000 ÷ 750 = 32 bottles
Step 4: Total Cost
32 × 12 = $384
Step 5: Cost Per Guest
384 ÷ 40 = $9.60 per guest
