What is the ratio of material to labor cost in aviation?

In aviation, the ratio of material to labor cost can vary significantly depending on the specific sector and context, such as manufacturing, maintenance, or operation. Generally, material costs can account for about 30-50% of total costs, while labor costs may range from 50-70%. This means the ratio of material to labor costs is often around 1:2 to 1:3. However, these figures can fluctuate based on factors like technology, labor intensity, and the complexity of the aircraft.
