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.

    Frequently Asked Questions

    What if some contributors bring more than others?

    That is normal and fine. The calculation gives a minimum target per person. Main entrees typically need more servings than a side salad. Communicate the target so contributors know the scale.

    How do I coordinate so everyone does not bring the same thing?

    Create a shared sign-up sheet (digital or paper) with categories: main dishes, sides, salads, desserts, drinks, and paper goods. Assign or let people choose categories. This ensures variety.

    Should the host cook too?

    It is considerate for the host to provide at least one main dish, beverages, and the paper goods. This sets the tone and ensures there is always a base amount of food even if a contributor does not show up.
