Build panel selling price from material cost plus edgeband, overhead and margin
Work out a panel combo's selling price by adding material, edgeband, overhead and margin costs.
To arrive at a panel combo's selling price, add the per-SFT costs of the external finish, the core ply/board and the inner laminate.
Then add an edgeband allowance converted to a per-SFT rate.
Edgeband is bought in running feet but the template needs a surface-area rate, so estimate it from the smallest panel size (e.g. all four sides banded on a small panel) and divide by that panel's area.
Add any manufacturing overhead percentage and the desired profit margin on top.
The resulting price is exclusive of GST.
