Year-over-Year (YoY) Growth: Measuring Business Performance
Learn how to calculate YoY growth and why it's a better metric than month-over-month comparisons.
When businesses report their earnings, they almost always highlight their Year-over-Year (YoY) growth. But what exactly is it, and why is it so widely used?
What is YoY Growth?
YoY growth compares a financial metric (like revenue or active users) from one period to the same period in the previous year. For example, comparing Q1 2024 to Q1 2023.
The Formula
YoY Growth = [(Current Year Value - Last Year Value) / Last Year Value] * 100
Why YoY is Superior to MoM
Month-over-Month (MoM) growth can be misleading due to seasonality. A retail store might see a 50% increase in sales in December compared to November, but that doesn't necessarily mean the business is booming—it just means it's Christmas.
By comparing December 2024 to December 2023, you remove the seasonal effect and see if the business is truly improving.
How to Interpret the Numbers
- Positive YoY Growth: The business is expanding compared to the previous year.
- Negative YoY Growth: The business is shrinking, which may signal a need for strategic changes.
