YoY (Year-over-Year)
A comparison of a business metric for one period with the same period from the previous year.
Definition
Year-over-Year (YoY) growth compares performance metrics from one year to the same period in the previous year, accounting for seasonal variations and providing a clear view of long-term growth trends.
How to Calculate
YoY Growth = ((Current Year - Previous Year) / Previous Year) × 100
Real-World Example
Revenue Growth: $2M revenue this year vs $1.5M last year
YoY Growth = (($2M - $1.5M) / $1.5M) × 100 = 33.3%
