Halloween Candy Calculator: How Much Candy to Buy

Short answer: plan on about 2 fun-size pieces per trick-or-treater, plus a 10% buffer. Expecting 50 kids? Buy roughly 110 pieces — about 4 standard bags. Expecting 100? Around 220 pieces, or 7–8 bags. The calculator below adjusts that math for your street, your weather and the candy your own household will quietly eat before the big night.

Calculate your candy


Most homes do 2–4 hours (roughly 5:30pm to 8:30pm).


Not sure? Ask a neighbour, or use last year’s count. Decorated houses on lit streets get 2–3x the traffic of plain ones.



Halloween 2026 falls on a Saturday, which usually pushes turnout up — the calculator’s street rates already assume a normal year, so busy streets may want the next level up.




The “sneaky factor”: candy bought early gets eaten early. We add 1 piece per snacker per day between now and Halloween.

Round up, not down: running out at 7pm with kids still on the street is worse than a leftover bag in November.

What changes the math?

Weather. Cold cuts turnout somewhat; real rain can nearly halve it — kids stay on their own blocks instead of roaming. Your display. A decorated, well-lit house pulls in extra visitors who detour to the “fun” houses. The day of the week. Weekend Halloweens (like 2026’s Saturday) run busier than weeknights. The unsupervised bowl. A “take one” bowl empties faster than hand-served candy — budget extra if you’re leaving a bowl out.

Frequently asked questions

How many pieces of candy per trick-or-treater is normal?

Two fun-size pieces is the common standard. One is fine on very busy streets; three makes you the house kids remember next year.

When should I buy Halloween candy?

The second-to-last week of October hits the sweet spot: full shelves, sale prices, and not enough time at home for the bag to be raided before Halloween.

How much candy do I need for 100 trick-or-treaters?

About 220 fun-size pieces at 2 per child plus a 10% buffer — roughly 8 standard 30-piece bags.

Is it better to buy too much or too little?

Too much, by a little. Unopened bags keep for months and most stores take returns on sealed candy; running out means turning off the porch light early.
