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.

Quick reference: how much candy for how many kids?
| Expected trick-or-treaters | Pieces needed (2 each + 10%) | Standard bags (30 pcs) |
|---|---|---|
| 25 | 55 | 2 |
| 50 | 110 | 4 |
| 75 | 165 | 6 |
| 100 | 220 | 8 |
| 150 | 330 | 11 |
| 200 | 440 | 15 |
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.
