This method helps measure long-term trends and eliminates seasonal fluctuations. By measuring growth or decline over a full 12-month period, YoY eliminates short-term fluctuations and seasonal variations, providing a clearer picture of overall progress. A company had $110 million in revenue in 2018, compared to $100 million in 2017. In other words, revenue increased by $10 million compared to the previous year, which amounts to a 10% YoY revenue growth. It often fails to account for extraordinary or one-time events that distort comparisons. For example, a major acquisition or divestiture in the previous year might skew YOY figures, making it difficult to assess organic growth.

For retail and e-commerce businesses, YOY analysis is invaluable for tracking sales growth, customer acquisition, and inventory management. Since many retail businesses experience seasonal fluctuations, comparing sales from the same periods across years helps smooth out msci emerging market index today seasonal variations and gives a clearer picture of overall growth. Have you ever wondered if your business is really growing, or if that spike in sales is just a seasonal fluke? Year-over-Year (YOY) analysis is one of the best ways to get a clear picture of your company’s true performance over time.

Consistent Timeframes for Accurate Comparison

YOY analysis is a simple yet powerful tool that can give you a clear, long-term view of your business performance. By comparing key metrics like revenue, customer acquisition, and profitability year over year, you can identify trends, measure growth, and make informed decisions for the future. Year-over-Year (YOY), also known as year-on-year, is an essential metric in financial analysis, employed to compare data from the current year against the previous one. This analytical method is pivotal for understanding the changes in key financial metrics such as revenues, expenses, and profits over annualized periods. By evaluating these changes, finance professionals can discern growth trends, identify patterns, and make informed strategic decisions. Year-over-year (YOY) is a metric that compares a specific data point (such as revenue, profit, or customer acquisition) from one time period to the same period in the previous year.

Year-over-year (YOY) is a technique for comparing two or more quantifiable events over a yearly period. It is part of key performance indicators used to compare a company’s growth or performance yearly. Investors and analysts easymarkets broker review frequently apply this analytical tool to create accurate comparisons and evaluate long-term trends. Sales performance is one of the most commonly analyzed metrics with YOY comparisons.

• Month-over-month (MOM) comparisons can provide even more granular data, making it possible to detect subtle shifts in a company’s performance.
• This level of granularity is especially useful for businesses in fast-changing industries or those making rapid strategic changes.
• Following is the year-over-year number of patients and cost per patient comparison on a monthly basis.
• The importance of YOY lies in its ability to remove short-term volatility and focus on long-term trends.

To properly quantify a company’s performance, it makes sense to compare revenue and profits YOY. The author may casually state “the Q3 earnings were $2.25 which was a 50% increase YoY” and then go on to state changes in the company or economy that led to the change. 2) Suppose that an author is writing an article about a quarterly earnings release issued by a particular company. The author may mention the quarterly eps and would like to express a frame of reference so the user is not just seeing random numbers.

Limitations of YoY Analysis

For instance, ski resorts, beach hotels, and seasonal eateries often experience significant fluctuations in business activity based on the time of year. It is common for companies to identify their annual growth for specific metrics such as sales, expenses, revenue, and, most importantly, profit. Comparing one specific year to a prior year makes it easier to assess whether performance has increased and by how much. Another limitation of YOY analysis is that it does not account for seasonality, which is critical for businesses with seasonal demand such as ski lodges or beachfront hotels. These businesses’ revenue varies significantly across seasons, which YoY analysis may not accurately reflect.

Year-to-date analysis compares the variable data between the beginning of the current year and the same of the previous year. Because of this, it makes much more sense to compare quarterly financials on a YoY basis. It’s also common to compare quarterly financials on a YoY basis – as in, whether financials improved or worsened compared to the same quarter a year earlier. For example, seasonality (how certain seasons affect revenues) is not accounted for in a YoY analysis. Businesses located in holiday destinations such as ski resorts, hotels, and restaurants suffer from high seasonality, which should be accounted for in financial reports. Knowing this information can lead to significant cost savings by shutting down operations in the off-season.

One could either say “Variable X is down 90% Y/Y” or they could say “This year’s numbers are 10% of what they were last computer vision libraries year”. These two statements obviously do not use the same math and the YoY formula is related to the former and not the latter. Both this formula and the formula at the top of the page are the same, only rearranged. The denominator of X0 can be factored out to get the formula at the top of the page.

Definition: WHAT Is Year-Over-Year Growth?

If you compare data from different periods, such as comparing Q with Q2 2024, the results may be skewed, as you’re not comparing like-for-like periods. An excellent example of this is Meta’s (formerly Facebook) 2021 financial highlights from its investor page. The statement shows the year-over-year changes for a three-month period from the end of 2021 and the period December 2020 to December 2021. Other business metrics or economic data will be necessary to explain why a company is growing or slowing down.

• Many SaaS companies have recurring revenue models, so understanding YOY trends in customer acquisition, churn rates, and subscription renewals is vital for maintaining growth.
• It is a much shorter period compared to YTD, but it is very useful in reporting interim monthly performance.
• Companies that regularly track these patterns can make more informed pricing, cost management, and operational decisions.
• YOY calculations can also be applied to various aspects of a business, from revenue and costs to customer base and market share.
• The value of business reports lies in how they present information clearly and concisely.

In Year 1, we divide $104m by $100m and subtract one to get 4.0%, which reflects the growth rate from the preceding year. Our first step is to project the company’s revenue and operating income (EBIT) using the following assumptions. Late-stage, mature companies with established market shares are less likely to allocate funds to facilitate more growth (e.g. reinvestment, capital expenditures).

Compared to compound annual growth rate (CAGR), which measures average growth over multiple years, YOY highlights year-to-year fluctuations. A company with a 10% CAGR over five years might have experienced significant annual volatility, such as a 20% drop followed by a 30% rebound. YOY analysis captures these fluctuations, offering a more detailed view of performance dynamics. The main benefit of YoY growth analysis is how easy it is to track and compare growth rates across several periods.

For example, if this year’s X is 800 and the prior year’s X is 1,000, the decrease is 20% YOY. If you use the formula at the top of the page, this would be -200 divided by 1000, which results in -20%. Occasionally, a nonpercentage number may be quoted, but in these examples, only simple subtraction is used and the writer is simply using this phrase to convey “a difference from one year to the next”. Streamline your startup finances with an all-in-one multi-currency business account. Let’s go through a few real-life examples to better understand how to apply the YOY growth formula in different scenarios. A high retention rate signals strong customer satisfaction and loyalty, whereas low retention rates might indicate that your products or services aren’t meeting customer expectations.

Business finance terms, explained simply.

The same formula can also be used to calculate the YTD for sales, marketing campaigns, company costs, demand and supply, and many more. It is also a key metric in investing, where it is used to show the returns from an investment or portfolio. When you measure the performance of one metric now and compare it against a different period, you can understand what direction your business is taking and act appropriately. For example, retailers have a peak demand season during the holiday shopping season, which falls in the fourth quarter of the year.

Some businesses also use compound monthly growth rate (CMGR) to show growth over a given number of months. YTD returns can also be used to compare performance with a different year for the same time period. Analyzing current performance against historical data reveals what trends are taking place.
