YoY Calculator

(YoY) growth compare the values of a specific metric or variable for the same month or period in two different years. Year-over-year growth is a common metric for assessing performance and changes over a longer time horizon. Here's the formula to calculate YoY Growth:

YoY Growth = [(Current Year Value - Previous Year Value) / Previous Year Value] x 100

Current Year Value: Determine the value of the metric you want to analyze for the current year.

Previous Year Value: Determine the value of the same metric for the previous year.

What is Year-on-Year (YoY)?

Year-on-year simply means comparing one period of data of one year to that of the previous year. For instance, you can compare how many sales you made in December this year with your sales in December last year, thereby helping you see how your business is evolving over time.

Why is YoY comparison important?

The YoY metric shows you how your business is growing over time. It's a straightforward way to see how well you're doing compared to the same period last year.

By looking at YoY data regularly, you can spot trends in your business. For instance, if your sales increase every December, you might decide to stock more products during that time.

Understanding whether your business is growing or shrinking helps you understand the state of your business. It is better to change your strategy or explore new ways to attract customers if the rate is consistently declining, or if you see an increase in sales every year, you can plan for similar growth or better the following year.

How to Use the YoY Calculator?

You only need two pieces of information:

• Your data from the current year (this year's sales).
• Your data from the previous year (last year's sales).

Enter these numbers into the YoY calculator, and it will give you the percentage change. This percentage is a very useful indicator of your business's health.
