How It Works

How to Plan Potluck Portions

Formula

Total Servings = Guests x Dishes per Guest

Servings per Contributor = ceil(Total Servings / Contributors)

At a potluck, each guest typically samples 4-6 different dishes. Each contributor should bring enough servings so that every guest can try their dish if they want to.

Planning Tips

  • Assign categories: 2-3 entrees, 3-4 sides, 2-3 desserts, 1-2 salads
  • Ask contributors to label allergens and ingredients
  • Provide serving utensils for each dish
  • Have a couple of contributors bring drinks and paper goods

    • Worked Example

    20 guests with 8 contributors, each guest sampling 5 dishes.

    guests = 20contributors = 8servings_per_guest = 5
    1. 01Total servings = 20 x 5 = 100 servings
    2. 02Per contributor = ceil(100 / 8) = 13 servings each
    3. 03This means each person brings a dish that serves 13.
