Learning Curve 80% Rule Calculator

Calculate manufacturing or task learning curves using the 80% rule: Yₙ = Y₁ × n^b where b = log(learning rate)/log(2). An 80% learning curve means unit cost drops to 80% each time cumulative output doubles.

How It Works

Calculate manufacturing or task learning curves using the 80% rule: Yₙ = Y₁ × n^b where b = log(learning rate)/log(2). An 80% learning curve means unit cost drops to 80% each time cumulative output doubles

Each component has a specific meaning:

  • 80% rule: Yₙ = Y₁ × n^b where b = log/log — The 80% rule: yₙ = y₁ × n^b where b = log/log recorded for the scenario being assessed.

Note: Interpret the learning curve 80% result against the thresholds and context described above.

How to Use

Enter the 80% rule: Yₙ = Y₁ × n^b where b = log/log for the scenario you are assessing. Calculate manufacturing or task learning curves using the 80% rule: Yₙ = Y₁ × n^b where b = log(learning rate)/log(2). An 80% learning curve means unit cost drops to 80% each time cumulative output doubles. Use the learning curve 80% result to inform your calculation.
