Year over Year (YoY) growth measures how fast a metric (typically ARR, MRR, or revenue) has grown in the past 12 months. This holds of quarterly aggregation: whatever month the current quarterly metric is as of (dependent on date aggregation and range), YoY growth will compare to 12 months prior. If looking at April 2023 YoY growth:
YoY Growth = (April 2023 ARR÷April 2022 ARR)—1
