What Is Material Utilisation?
Material Utilisation measures how much of the raw material input ends up in the finished product. The remainder is waste — trim, chips, offcuts, scrap, and process losses.
In many manufacturing operations, material is the single largest cost component. Even small improvements in utilisation can have significant financial impact.
The Formula
Material Utilisation = (Finished Product Weight ÷ Raw Material Weight) × 100%
Or by units:
Material Utilisation = (Good Units × Material per Unit) ÷ Total Material Used × 100%
Data Requirements
| Source | Required | What You Need |
|---|---|---|
| Machine Data | Yes | Production count, good units |
| ERP | Yes | Material specifications, costs, inventory consumption |
| MES | Yes | Material consumption tracking, batch tracking |
Material Utilisation is a Phase 3 metric — it requires integration between production data and inventory/material systems.
Why It Matters
- Cost reduction — material is often 40–70% of production cost; small utilisation gains yield large savings
- Waste minimisation — environmental and economic benefit
- Process optimisation — low utilisation reveals inefficient processes or poor tooling
- Supplier quality — material variation directly affects utilisation
Common Pitfalls
- Not distinguishing normal process waste (trim, kerf) from avoidable waste (scrap, excess)
- Difficult to measure accurately without automated tracking
- Comparing utilisation across different products or processes without context
Best Practices
- Track by product family for meaningful comparison
- Identify processes with the lowest utilisation for improvement focus
- Calculate the cost impact of utilisation improvements to build business cases
- Balance utilisation improvement with quality requirements — sometimes waste reduction compromises product integrity
- Consider nesting optimisation, tooling changes, or material substitution as improvement levers
Related Metrics
- Scrap Rate — scrap directly reduces material utilisation
- First Pass Yield — FPY failures waste material
- Cost per Unit — material utilisation is a major driver of unit cost
