Use this calculator to price non-standard sizes, colors, grids, hardware, glass options, special jamb depths, project documentation, or dealer-specific requirements.
What this calculator does
- Estimate custom-order premium from custom openings, premium per opening, applied scope, and engineering adders.
- deciding whether a custom fenestration order needs an upcharge
- The result estimates the premium needed to cover custom-order complexity.
Formula used
- Variable customization premium = custom openings or configured units × custom premium per opening × customization premium scope included
- Total customization premium = variable customization premium + fixed engineering and order-entry adder
Inputs explained
- custom openings or configured units: Use the number of windows, doors, lites, or assemblies with non-standard sizes, colors, hardware, glass, grids, or documentation.
- custom premium per opening: Use price-book adder, engineering estimate, extra labor/material cost, or historical premium needed for similar custom work.
- customization premium scope included: Use 100% for all custom options or less for selected features, dealer groups, or product lines.
- fixed engineering and order-entry adder: Include shop drawings, approvals, programming, special purchasing, project management, and order-entry support.
How to use the result
