How Do You Calculate Productivity Growth Rate

Productivity Growth Rate Calculator

Productivity growth is a fundamental driver of economic prosperity. It measures the increase in output per unit of input over time. Understanding and tracking productivity growth is crucial for businesses and policymakers to assess efficiency, competitiveness, and long-term economic health.

The productivity growth rate is typically calculated by comparing the change in output per unit of input between two periods. A common way to measure this is by looking at labor productivity, which is the ratio of output to labor input. The formula for productivity growth rate is:

Productivity Growth Rate = [(Output Per Worker (Year 2) – Output Per Worker (Year 1)) / Output Per Worker (Year 1)] * 100

Where:

  • Output Per Worker (Year 2) is the total output divided by the total labor input in the later period.
  • Output Per Worker (Year 1) is the total output divided by the total labor input in the earlier period.

A positive growth rate indicates that productivity has increased, meaning more output is being produced with the same or fewer inputs. A negative growth rate suggests a decline in productivity.

Calculate Productivity Growth Rate









function calculateProductivityGrowth() { var outputYear1 = parseFloat(document.getElementById("outputYear1").value); var laborYear1 = parseFloat(document.getElementById("laborYear1").value); var outputYear2 = parseFloat(document.getElementById("outputYear2").value); var laborYear2 = parseFloat(document.getElementById("laborYear2").value); var resultDiv = document.getElementById("result"); resultDiv.innerHTML = ""; // Clear previous results if (isNaN(outputYear1) || isNaN(laborYear1) || isNaN(outputYear2) || isNaN(laborYear2)) { resultDiv.innerHTML = "Please enter valid numbers for all fields."; return; } if (laborYear1 <= 0 || laborYear2 <= 0) { resultDiv.innerHTML = "Labor input must be a positive number."; return; } var outputPerWorkerYear1 = outputYear1 / laborYear1; var outputPerWorkerYear2 = outputYear2 / laborYear2; if (outputPerWorkerYear1 === 0) { resultDiv.innerHTML = "Productivity in Year 1 is zero, cannot calculate growth rate."; return; } var growthRate = ((outputPerWorkerYear2 – outputPerWorkerYear1) / outputPerWorkerYear1) * 100; resultDiv.innerHTML = "

Results:

"; resultDiv.innerHTML += "Output Per Worker (Year 1): " + outputPerWorkerYear1.toFixed(2) + ""; resultDiv.innerHTML += "Output Per Worker (Year 2): " + outputPerWorkerYear2.toFixed(2) + ""; resultDiv.innerHTML += "Productivity Growth Rate: " + growthRate.toFixed(2) + "%"; }

Example Calculation

Let's consider a small manufacturing company. In Year 1, the company produced 10,000 units of goods (output) and had 50 employees working full-time (labor input). In Year 2, the company produced 12,000 units of goods (output) with the same 50 employees (labor input).

  • Output Per Worker (Year 1) = 10,000 units / 50 employees = 200 units/employee
  • Output Per Worker (Year 2) = 12,000 units / 50 employees = 240 units/employee
  • Productivity Growth Rate = [(240 – 200) / 200] * 100 = (40 / 200) * 100 = 0.20 * 100 = 20%

In this example, the company experienced a productivity growth rate of 20%. This indicates a significant improvement in efficiency.
