Boards = ceiling(perimeter × (1 + waste%) ÷ stock length). Crown defaults to 15% waste for compound-miter miscuts; baseboard 10%.

Each corner needs 2 miter cuts; wall runs longer than one stock board add scarf joints (2 bevel cuts each).
One 10-oz caulk tube seals about 75 linear feet of trim, top and bottom edges.
Boards = gross LF ÷ stock length
For a 14x10 ft room: perimeter is 48 lin ft x 1.10 waste = 52.8 ft, so ceil(52.8 / 16) = 4 sixteen-foot boards, plus 1 tube of caulk.
Each corner needs 2 miter cuts — a square room means 8 miters. Add scarf joints (2 bevel cuts each) wherever a wall run exceeds your stock board length.
Crown molding defaults to 15% waste for compound-miter miscuts; baseboard uses 10%. Boards are rounded up to whole stock lengths either way.
One 10-oz tube of painter's caulk seals about 75 linear feet of trim, covering both the top and bottom edges.
Boards = ceiling(perimeter x (1 + waste%) / stock length). The tool applies the 15% crown waste factor and rounds up so you never come up short.
