What is Year-over-Year (YoY) growth?

Year-over-Year (YoY) growth compares a metric against the same period last year. Formula: YoY = (Current Value - Last Year Value) / Last Year Value × 100%. It eliminates seasonal fluctuations and reveals true business growth. Example: Q1 revenue of $1M this year vs $800K last year = 25% YoY growth.

What's the difference between YoY and QoQ/MoM?

YoY compares to the same period last year — eliminates seasonality. QoQ (quarter-over-quarter) and MoM (month-over-month) compare to the immediately preceding period — shows short-term trends. For example, December retail may spike vs November (high MoM) due to Christmas, but vs last December reveals real growth (YoY). This tool focuses on YoY.

What's a good YoY growth rate?

It depends on industry and stage. SaaS startups often target 30%+ YoY growth. Mature companies at 10-20% is excellent. Negative growth is a warning sign but not always alarming — external factors like a pandemic can cause temporary dips. Focus on sustained trends, not single data points.
