Year-Over-Year Growth Calculator

What is YoY growth?

Year-over-year (YoY) is a key performance indicator that measures the percentage change in a particular metric over a one-year period. It is usually used to track an organization’s performance in various areas.

Calculating YoY growth over monthly changes helps you to overcome effects of seasonality or monthly volatility to give you a clearer and more accurate picture of your performance. This can help you to make data-driven decisions about long term business goals.

How to use the YoY growth calculator

To calculate YoY growth, enter the current year’s value and the previous year’s value into the calculator. These values can be for various metrics such as:

  • Revenue
  • Organic traffic
  • Customer base

The tool will instantly calculate your YoY growth rate, showing your percentage increase or decrease in the given metric in a particular year.

Understanding the YoY growth result

The ideal YoY growth depends on your goals and the metric that you are measuring. Your YoY value can be either positive or negative.

  • A positive YoY growth indicates an increase in the metric being measured. The higher the value, the better is the performance in the area that you are measuring.
  • A negative YoY indicates a decrease in the given metric. This indicates potential challenges and decline of performance in the given metric.

When to calculate YoY growth

Yoy growth should be calculated regularly to monitor your long-term performance in key metrics. Here are some key situations where you might want to calculate YoY growth:

  • During annual financial reviews to assess overall business growth
  • When comparing different time periods to identify seasonal trends or patterns
  • To evaluate the impact of new marketing campaigns or product launches
  • To gauge market demand and competitive positioning in your industry
  • To benchmark your company's growth against competitors or industry standards

How to calculate YoY growth with example

Let’s say that your business generated $1,200,000 in revenue this year compared to $1,000,000 in revenue last year. You can calculate YoY growth rate as follows:

YoY Growth (%) = [(Value in Current Year−Value in Previous Year​)/Value in Previous Year] ×100

YoY growth = (200,000/1,000,000) × 100 = 20%

In this example, your YoY growth is 20%, indicating that your revenue increased by 20% from the previous year.
