What is the formula for the learning curve rate?

• A. Incremental Unit Cost at a given rate of production divided by Incremental Unit Cost at double the rate of production
• B. Incremental Unit Cost at double the rate divided by Incremental Unit Cost at a given rate of production
• C. Current rate times doubling rate
• D. Difference between 2x and x unit costs

Answer: (A)

The learning curve rate shows how unit cost declines as experience and efficiency improve with production. It’s quantified by comparing the incremental cost at a given production rate to the incremental cost when production is doubled. That is, the learning curve rate equals the incremental unit cost at the current rate divided by the incremental unit cost at double that rate. This ratio captures the cost savings gained from learning; if the cost with doubling is lower, the ratio will be greater than one, reflecting the improvement. For example, if the incremental cost at the current rate is $10 and at double the rate it’s $8, the ratio is 10/8 = 1.25, which corresponds to a 20% cost reduction when production doubles.
