Material Utilization Rate Explained
Material utilization rate (also called yield or efficiency) is the percentage of your stock that becomes usable parts rather than scrap. It is the single clearest measure of how well a cutting plan performs, and small improvements translate directly into lower material cost.
The formula
Utilization rate = (total area of parts ÷ total area of stock used) × 100. If you cut 24 m² of parts from 30 m² of sheets, utilization is (24 ÷ 30) × 100 = 80%. The remaining 20% is waste — kerf, offcuts, and trim.
What counts as good
- Below 70%: significant waste; the layout or part mix needs work.
- 70–80%: typical for manual or simple layouts.
- 80–90%: a well-optimized layout with good part variety.
- Above 90%: excellent, usually with small filler parts and few grain constraints.
What lowers utilization
- Large parts that leave awkward unusable offcuts.
- Grain-direction rules that prevent rotating parts.
- Wide kerf from thick blades on many cuts.
- Cutting jobs separately instead of combining part lists.
How to improve it
Combine multiple jobs so parts share sheets, mix part sizes so small parts fill gaps, reuse offcuts, and let an optimizer test thousands of arrangements. CutList Machine reports the utilization rate for every layout so you can see the impact of each change.
Frequently asked questions
Is utilization rate the same as yield?
Yes. Utilization rate, yield, and material efficiency all describe the share of stock that becomes usable parts rather than waste.
Can utilization ever reach 100%?
In practice, no. Kerf and trim always remove some material, so even perfect layouts fall a few percent short of 100%.
