Measure mining efficiency by calculating Labor Productivity, Total Factor Productivity (TFP), and Cost Per Unit (CPU) to gain insights into operational and strategic performance.
Labor Productivity (LP) = Total Physical Output / Total Labor Hours
Total Factor Productivity (TFP) = Value of Output / (Cost of Capitalβ × Cost of Laborα)
Cost Per Unit (CPU) = (Labor Cost + Capital Cost + Other Costs) / Total Physical Output
Note: α (Alpha) and β (Beta) represent the elasticity of labor and capital, typically 0.7 and 0.3 respectively.

Example 2 (Cost Per Unit):
Mining is a capital-intensive industry where efficiency dictates survival. The Mining Productivity Calculator is a specialized tool designed to help mine managers, engineers, and financial analysts quantify the performance of extraction operations. Unlike generic productivity tools, this calculator addresses the specific "dualism" of mining productivity: it measures both the operational efficiency of the workforce (Labor Productivity) and the strategic efficiency of capital investment (Total Factor Productivity).
At the operational level, the Mining Productivity Calculator calculates Labor Productivity (LP). This metric—often expressed as tons per man-hour—is crucial for daily shift management. It helps identify bottlenecks in staffing or workflow. However, focusing solely on labor can be misleading in modern mining, where heavy machinery does the heavy lifting. That is why our tool also calculates Total Factor Productivity (TFP). Using the Cobb-Douglas production function, TFP assesses how efficiently combined inputs (labor and capital) are converted into value. A rising TFP indicates that the mine is adopting better technology or management practices, rather than just adding more machines.
Finally, the Mining Productivity Calculator computes the Cost Per Unit (CPU). In an industry where commodity prices are set by the global market, controlling the cost per ton or ounce is the primary lever for profitability. As noted by industry authorities like the U.S. Geological Survey (USGS), efficient resource utilization is critical for economic viability. Furthermore, concepts of production theory used here are widely supported by economic resources such as Wikipedia. This calculator brings these complex economic models into a simple, actionable interface for your business.

Labor Productivity measures output relative to a single input: labor hours. It is an operational metric. Total Factor Productivity (TFP) measures output relative to all inputs (labor and capital). TFP is a strategic metric that indicates technological efficiency and management effectiveness.
Mining companies are "price takers," meaning they cannot control the market price of the metal or mineral. Therefore, the only way to increase profit margins is to lower the cost of production. CPU is the direct measure of this efficiency.
These represent the output elasticity of labor and capital in the Cobb-Douglas production function. In standard economic modeling for mining and heavy industry, Labor Share (α) is often estimated at 0.7 and Capital Share (β) at 0.3. You can adjust these if your specific operation has a different capital/labor intensity ratio.
Yes. Please enter fuel, electricity, and explosives costs into the "Other Costs" field. These will be included in the Cost Per Unit (CPU) calculation to ensure accuracy.
