Moore's Law Calculator

Apply Moore's law (density doubling roughly every 2 years) to project a future value, plus the number of doublings, growth multiple, and annual growth rate.

Input

Starting value (e.g. transistor count)

units

Years elapsed

Doubling time (years for density to double)

Result

Projected value after 10 years

73,600units

Number of doublings

5×

Growth multiple

32×

Annual growth rate

41.4 %

Doublings (years ÷ doubling time)	5×
Growth multiple (= 2 ^ doublings)	32×
Projected value	73,600 units
Average annual growth rate	41.4 %/yr

How it works

Enter the starting value, years elapsed, and doubling time; the projection is computed as starting value × 2^(years ÷ doubling time).
The doubling time defaults to 2 years. Change it freely to model paces such as about 1.5 or 3 years.
The number of doublings is years divided by the doubling time, and the growth multiple is 2 raised to that number of doublings.
The annual growth rate is the average yearly increase (%) when the growth multiple is spread evenly across the elapsed years.
When the projected value becomes very large, scientific notation is shown alongside it for readability.
This tool is an approximation for understanding exponential growth and does not guarantee actual semiconductor progress or future physical limits.
