| Raw Chemical Feedstock |
Variable |
Treat as direct unit economics. For Organic Red Pigment, this starts at $12 per unit before labor, packaging, energy, and disposal. |
Blending it into factory overhead and hiding margin by pigment line. |
| Direct Production Labor |
Variable |
Apply per produced unit, from $3 per unit for Industrial White Base to $10 per unit for Custom Yellow Paste. |
Treating all plant labor as Variable instead of separating salaried plant management. |
| Production Energy |
Semi-variable |
Model a usage-linked charge by batch or unit, since energy runs from $1.00 to $2.00 per unit across the product set. |
Classifying all utilities as fixed and overstating margin at higher volume. |
| Waste Disposal and Hazardous Material Handling |
Variable |
Tie disposal to production volume and product mix. Custom Yellow Paste carries $3.00 per unit for hazardous material handling. |
Using one flat monthly waste estimate despite different handling needs by pigment type. |
| Quality Control Testing and Laboratory Consumables |
Semi-variable |
Use a revenue-linked burden because testing and consumables rise with batches, SKUs, and customer specifications. |
Leaving testing out of break-even until defects or rework hit cash. |
| Equipment Maintenance |
Semi-fixed |
Step maintenance up as production hours and equipment load increase, using the model’s 0.3% to 0.5% revenue range as a guide. |
Scaling maintenance smoothly with sales instead of planning capacity-triggered service jumps. |
| Facility Lease |
Fixed |
Keep the lease in monthly overhead at $25,000 from Month 1 through Month 60. |
Allocating rent per unit and assuming lower volume reduces the cash bill. |
| Lab Technician Headcount |
Semi-fixed |
Model headcount in steps: 2.0 FTE in the first year, rising to 6.0 FTE by the mature year. |
Hiring too late because the model treats lab work as a perfect variable expense. |
