How it works

Three numbers, one shopping list

Estimate the crowd

Typical residential streets see 40–100 kids on Halloween. If you hand out at a school or apartment complex, expect more.

Set your per-kid rate

2 pieces is the polite standard; 3–4 if you are the "favorite house." We default to 2.5.

Slide the allergy share

Choose how much of your haul should be nut-free or non-food (stickers, crayons). We convert everything to bag counts based on common party-size packs.

Why this calculator?

Reddit and Facebook parents lose the candy math every October

Two recurring complaints: "I bought one huge bag and ran out by 7 PM" and "I bought one huge bag and had leftovers until March." Harvard nutrition and family groups both repeat the same advice: estimate by the number of kids on your street, not by grabbing the biggest bag. Add the Teal Pumpkin Project requirement (nut-free options for allergy kids) and the math gets fiddly. This tool does the arithmetic and bag-conversion in two seconds.

Why buy allergy-friendly candy separately?
The Teal Pumpkin Project encourages offering non-food or nut-free options so kids with allergies can participate. Mark your door with a teal pumpkin and keep a separate small bowl.
How many pieces do kids usually take?
Industry guidance is 2 pieces per kid as a base, but older groups often take 3–4. We default to 2.5 and let you adjust.
What if I run out?
Buy one extra small bag as a buffer. Harvard nutrition also suggests not over-buying: leftover candy is a real household problem by November.
