About this calculator
Explore a candy scenario from your route assumptions. The model uses about 11 g and 45 kcal per piece, assumes the same number of houses for each child, and does not model queues, walking distance, or route delays; actual portions and labels vary.
Worked example
calculated with the default values below
Trick-or-treaters in your group 2 · Hours trick-or-treating 2 hours · Minutes per house 1.5 minutes · Pieces given per visitor 2 · Candy eaten on the night 20 % Houses visited 80 · Total pieces collected 320 · Pieces per child 160.0 · Eaten on the night 64 · Pieces left afterwards 256 · Weight of candy 7.76 lb · Total calories 14,400

Frequently asked questions
How does group size affect the candy estimate?
The tool estimates houses visited as floor(hours × 60 ÷ minutes per house), then gives each child that many houses × pieces per house. At the defaults, 80 houses at two pieces each means 160 pieces per child; two children make 320 total before the 20% eaten estimate. The model assumes every child receives candy at each house and does not slow the route as group size grows.
How are candy weight and calories estimated?
The model assumes about 11 grams and 45 calories per piece. Actual piece sizes and nutrition labels vary, so treat the weight and calorie totals as rough scenario estimates.
