- Year-over-year (YOY) is a method of evaluating two or more measured events to compare the results at one period with those of a comparable period on an annualized basis.
- YOY comparisons are a popular and effective way to evaluate the financial performance of a company.
The formula used to calculate the year over year (YoY) growth rate is as follows:
YoY=\left(\frac{A}{B}-1\right)\cdot100\%,
Where
YoY | Year-Over-Year |
A | Current Period Value (this year) |
B | Previous Period Value (last year) |
