Cumulative units

Every time cumulative production doubles, the cost per unit falls by a fixed percentage — the learning curve. An 80% curve means the 200th unit costs 80% of the 100th. This steady, predictable decline, first seen in aircraft manufacturing, drives the falling prices of everything from solar panels to microchips, and underpins production planning and pricing.

Cost reduction77%

Governing equation

C_{n} = C_{1} n^{- b}, b = - lo g_{2} (0.80) = 0.322

Reading this result: An 80% curve means every doubling of output trims 20% off the unit cost — so by unit 100 you are paying about $23, a 77% drop from the first unit. Lower rates bend the curve down faster.
