Door Hardware Cost at 72% door hardware scope included: a worked example
Here is what the math looks like when conditions slip. We hold every other input steady and drop door hardware scope included to 72%, then walk the calculation through step by step. Estimate door hardware cost from hardware set count, cost per set, included scope, and fixed adders.
The inputs for this scenario
- door hardware sets: 95 sets (held at the documented default)
- cost per door hardware set: 74 $ / set (held at the documented default)
- door hardware scope included: 72 % (the input this scenario stresses; the baseline uses 100)
- fixed hardware kitting and prep adder: 480 $ (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Variable door hardware cost = door hardware sets × cost per door hardware set × door hardware scope included.
- total door hardware cost works out to 5,542 $ at these inputs, and this is the headline figure for the scenario.
- cost per hardware set works out to 58.33 $ / piece at these inputs.
- variable door hardware cost works out to 5,062 $ at these inputs.
- fixed hardware kitting and prep adder works out to 480 $ at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where door hardware scope included sits at 100% and the headline result is 7,510 $, this scenario comes in 26.21% below the baseline at 5,542 $.
- The practical read: the gap between this scenario and the baseline is entirely attributable to door hardware scope included, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats every hardware set as the same cost; a job that mixes a few high-end mortise locksets with cylindrical passage sets needs a weighted average input or it will mislead.
