Why parents plan candy this way
Kids per hour drives the math more than anything else. Watch one previous Halloween night, or ask neighbors, and you will rarely overshoot.
Most families eat a third of the candy before the big night. A 15% buffer bakes that honesty into your shopping list.
Standard 8–9 oz fun-size bags hold about 30 pieces each, so you never have to guess how many bags a number like "216 pieces" means.
At roughly $0.18 a piece, a busy-night haul can hit $40–$60 fast. Knowing the number first keeps the candy aisle honest.
The risk alert compares what you already bought against what you need, so the last kids at the door still get a treat.
