Compute year-over-year (YoY) percentage change between an initial year and a final year, and estimate the compounded annual growth rate (CAGR) across multiple years.
Prior year's value
Current year's value
Use 1 for simple YoY; >1 to get CAGR
Year over year compares a metric to the same metric in the previous year. It’s useful for removing seasonality and highlighting annual momentum.
YoY % = (Current − Prior) / Prior
CAGR = (Final / Initial)^(1 / Years) − 1
Initial year = 100; Final year = 120; Years = 1.
