Quantify the portion of output growth not explained by capital and labor inputs, often known as the "Solow Residual."
Total Factor Productivity (A) is calculated as the residual from the Cobb-Douglas production function:
Production Function: Y = A ⋅ Kα ⋅ Lβ
TFP Formula (Rearranged): A = Y / (Kα ⋅ Lβ)
An economy has an output (Y) of $20T, a capital stock (K) of $18T, labor hours (L) of 15B, with elasticities α=0.3 and β=0.7:
The Total Factor Productivity Calculator is an advanced economic tool that measures a crucial driver of long-term growth: Total Factor Productivity (TFP). Often referred to as the "Solow residual," TFP quantifies the portion of output growth that cannot be explained by the accumulation of traditional inputs like capital and labor. In essence, it's a measure of an economy's or firm's productive efficiency, capturing the impact of technological progress, innovation, and managerial improvements. This calculator uses the renowned Cobb-Douglas production function to isolate this "A" variable, providing a clear index of underlying efficiency.
Economic growth can come from two sources: using more inputs (more workers, more machines) or using existing inputs more effectively. While adding inputs can boost output, this path eventually faces diminishing returns. Sustainable, long-term growth in living standards comes from the latter—improving efficiency. This is precisely what TFP measures. The Total Factor Productivity Calculator requires five key inputs: Total Output (Y), Capital Input (K), Labor Input (L), and the respective output elasticities for capital (α) and labor (β). By providing these values, the tool calculates the residual "A" from the production function Y = A ⋅ Kα ⋅ Lβ, giving you a powerful snapshot of productivity.
The true power of TFP lies in tracking its growth over time. A rising TFP indicates that a firm or economy is getting more output from the same amount of capital and labor, which is the hallmark of genuine innovation and progress. For instance, the invention of the internet dramatically increased TFP across many industries by enabling more efficient communication and commerce without a proportional increase in physical capital or labor hours. As detailed by economic data providers like the Federal Reserve Bank of St. Louis (FRED), TFP growth is a key indicator of economic health. Our Total Factor Productivity Calculator allows you to apply this same analytical method to your own data sets, whether for academic purposes or business analysis.
This concept, thoroughly explored in economic literature and on platforms like Wikipedia, is fundamental to understanding why some economies grow faster than others. While the calculation may seem complex, our Total Factor Productivity Calculator simplifies the process, making it accessible to students, analysts, and business leaders. By using default, widely-accepted elasticity values (0.3 for capital and 0.7 for labor), the tool is ready to use out-of-the-box for high-level analysis. For anyone looking to move beyond simple productivity metrics and understand the deeper drivers of efficiency, the Total Factor Productivity Calculator is an indispensable resource.

Total Factor Productivity (TFP) is a measure of productive efficiency that captures the portion of output growth not accounted for by the growth in inputs like capital and labor. It reflects the impact of technology, innovation, and other efficiency improvements.
It's named after Nobel laureate economist Robert Solow. In his growth model, he demonstrated that capital and labor alone couldn't explain all of economic growth. The leftover, or "residual," portion he attributed to technological progress, which is now known as TFP.
They represent the output elasticities of capital and labor, respectively. In simple terms, they correspond to the share of national income paid to capital (profits, rent) and labor (wages). The standard values of α=0.3 and β=0.7 reflect the long-run observation that in many economies, capital receives about 30% of income and labor receives about 70%.
Yes, a higher TFP level indicates greater efficiency. However, the more important metric for analysis is the TFP *growth rate*. A consistently growing TFP is a primary driver of sustainable, long-term increases in economic prosperity and living standards.
