Trick-or-Treat Cheat Sheet: Shipt, Mars Wrigley Reveal Halloween Candy Algorithm


Birmingham, AL — With Halloween right around the corner, Americans will soon start wondering how much candy will be needed for anticipated trick-or-treaters, and which sweet purchased will ensure their house is a favorite on the block. To help, Shipt and Mars Wrigley have teamed up with a trick-or-treat cheat sheet, providing a heat map to help determine what candy will draw the most trick-or-treaters and a formula to guide the right amount of anticipated candy needed.

To calculate how many chocolates, chewing gum, mints or fruity confections are needed, the companies are encouraging consumers to use the following formula:

(T*K*G) + (D*F*S) = Candy Pieces divided by 30 = ?? Bags of candy

  • T = the time, in number of hours, you plan to leave the light on
  • = estimated number of kids per hour that ring the doorbell
  • = the generosity factor (how many pieces will be distributed to each trick-or-treater)
  • = the number of days between the initial candy purchase and Halloween
  • = the number of family members in the household
  • = the sneaky factor (average pieces of candy each member of the household will eat per day)

If rain is in the forecast, divide the final count by 1.5. 

“We want to be certain that no trick-or-treat bowl goes empty on Halloween night, which is why we meticulously broke down and analyzed candy shopping data to develop our very own candy formula, just in time for Halloween,” says Molly Snyder, Shipt’s Chief Communications Officer turned Chief Candy Officer. “Shipt is the perfect way to get candy as we deliver items in as soon as one hour. This way, sweet treats for Halloween can arrive at front doors just in time for trick-or-treaters.”

“With Halloween approaching quickly, Mars Wrigley is focused on continuing to demonstrate innovative ways to deliver better moments and smiles to consumers,” says Tim LeBel, president of Sales for Mars Wrigley US, also historically serving as Mars Wrigley’s Chief Halloween Officer. “Being able to partner with Shipt to help identify Americans’ candy needs and provide delivery by the hour for some of our most sought-after treats like Snickers, Twix and M&M’s will help ensure Halloween goes off without a hitch.”

Shipt is also using shopping data to reveal the most popular Mars Wrigley treats by state. The company found that Halloween day is the peak sales day for candy purchases The majority of states, 17 in total, prefer Snickers, while nine states prefer M&M’s, and perhaps the most unique state of all is Vermont, which prefers Life Savers.
