The smoothed path

How it works

The compound annual growth rate is the single rate that, applied every year, takes the start value to the end value: the ratio of end to start, to the power of one over the years, less one.

It smooths out the path, so two series with the same start and end have the same CAGR whatever happened in between. For a company’s revenue it is the growth figure quoted most often, and the one a forecast is usually judged against.

The same formula answers the other two questions: what a value becomes at a rate over a period, and how many years a target takes at a rate.
