Year Over Year Growth Calculator

Paste a series of yearly figures, oldest first, and this calculator returns the percentage change from each year to the next. It also gives the total growth across the whole run, the compound annual growth rate, and the plain average of the yearly rates, which is a different and always larger number. A second mode works the other way and says what annual rate a figure has to grow at to reach a target in a given number of years. It handles revenue, users, headcount or anything else counted once a year, and a year that starts from zero or from a negative figure is reported as undefined rather than given a meaningless percentage.
