What Is Year-Over-Year (YOY)?
Year-over-year (YOY)—also written as year on year—is one of the most common financial comparisons, which allows comparing two or more measurable events annually. It shows that a company’s financial performance is getting better, worse, or standing still.
You may read from financial reports that, for example, a business said it posted better revenues in the third quarter on a YOY basis over the past three years.
KEY TAKEAWAYS
- 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.
- Investors seeking to gauge a company’s financial performance use YOY reporting.
Year-Over-Year (YOY) Understanding
Year-over-year refers to comparing a business over one period in time versus its numbers for the same period one year earlier. This is considered more informative than a month-to-month comparison, which often reflects seasonal trends.
Common YOY comparisons include annual and quarterly versus monthly performance.
Benefits of Year-Over-Year (YOY)
YOY measurements enable the sets of data to be cross-compared. If an investor or financial analyst has a company’s first-quarter YOY data, they will see as many years of revenue in that quarter, and the trend of the company’s rising or falling revenue will be easily identifiable.
Comparing the same months in different years will lead to accurate comparisons despite the seasonal nature of consumer behavior.
The YOY comparison is also valuable for investment portfolios. Investors like to look over YOY performance, basically looking at how performance changes over time.
Uses of Year-Over-Year (YOY)
Comparisons on a YOY basis prevail in the analysis of corporate performance because it reduces seasonality, given that most businesses are affected by this element. Sales, profits, and other financial metrics change during different periods of the year since most lines of business have peak and low-demand seasons.
For example, many retailers have the fourth quarter as the peak demand time due to holiday shopping. To better quantify the performance of a company, it then makes sense to compare revenues and profits YOY.
This would be important to compare only the fourth-quarter performance in one year to the fourth-quarter performance of other years. Say an investor is looking at a retailer’s results in the fourth quarter as opposed to the prior—third—quarter; it may look like a company is experiencing unprecedented growth when seasonality is driving the difference in results.
For example, comparing it to the following first quarter when moving from the fourth quarter, it would seem like a steep drop, which again can just be an effect of seasonality.
It also differs from the term sequential, which measures one quarter or month to the previous one and allows investors to see linear growth: for instance, the number of cell phones a tech company sold in the fourth quarter, compared to the third quarter, or the number of seats an airline filled in January, as opposed to December.
Example of Year-Over-Year (YOY)
Below is the consolidated income statement of Apple for Q2 2024. Total net sales have been $90.8 billion for the second quarter. In 2023, Apple had a record second-quarter net sales of $94.8 billion. That means Apple’s net sales are down 4.3% year over year in Q2 2024 compared to last year’s period. 1
The company recorded net income for Q2 2024 at $23.6 billion versus in 2023 when Apple made $24.2 billion. It represents an on-year decrease of 2.2%. 1 Apple Inc. “Condensed Consolidated Statements of Operations Q2 2024, Page 1.”.
What is YOY used for?
YOY stands for year-over-year, which involves the comparison of one period of time versus another period one year earlier. This allows annualization—for instance, comparing third-quarter earnings this year and third-quarter earnings of the previous year.
The measure is always used to compare a company’s growth in profits and revenues. It can also denote changes at yearly frequencies in an economy that reflect the money supply, gross domestic product, and other economic measures.
How Is YOY Calculated?
YOY calculations are very simplistic and almost always written in percentage form. This, of course, would mean one takes the current year’s value, dividing it by the prior year’s value and subtracting one: this year ÷ last year -1. You can then multiply this by 100 to get a percentage.
What is the difference between YOY and YTD?
YOY refers to a 12-month change. On the other hand, year-to-date has changed compared to the beginning of the year, usually January 1. YTD may present a running total, whereas YOY will offer a comparative point.
What if I am interested in comparisons of less than one year?
You can calculate month over month or quarter over quarter the same way you do YOY. In fact, you can select any time period of your choice.
The Bottom Line
Year-over-year (YOY) is a useful tool for financial analysts, corporations, and investors. It allows for the comparison of financial figures from one point in time to the same point a year prior.
It paints a clear picture of performance—whether performance is improving, worsening, or static. This shows the firm how its business runs and whether any adjustments are necessary.
It shows investors whether adjustments in their portfolio are required, while analysts use it to tell a company’s financial health and make future predictions.

Q: What is the meaning of over year?
Ans: The phrase “over year” typically refers to a year-over-year (YoY) comparison, which is a financial analysis technique that compares a metric, such as revenue or profit, between the current year and the same period in the previous year.
For example, saying “revenue grew 10% over year” means that the current year’s revenue increased by 10% compared to the previous year’s revenue over the same time period.
The “over year” terminology emphasizes that the comparison is being made between the current year and the prior year, rather than a month-over-month or quarter-over-quarter comparison. This allows for an analysis of long-term trends and growth patterns.[5]
Q: How to calculate YoY decrease?
Ans: To calculate a year-over-year (YoY) decrease, you can use the same formula as calculating YoY growth, but the result will be a negative number:
YoY Decrease = (Current Year Value / Previous Year Value) – 1
For example, if revenue was $100 last year and $90 this year, the YoY calculation would be:
YoY Revenue Decrease = ($90 / $100) – 1 = -0.10 or -10%
This indicates a 10% decrease in revenue year-over-year.[5]
Q: What is the formula for year over year in Excel?
Ans: The formula for calculating year-over-year (YoY) growth in Excel is:
=($B$2/$B$1)-1
Where:
– $B$2 is the current year’s value
– $B$1 is the previous year’s value
This will give you the YoY growth rate as a decimal that can be formatted as a percentage.[2][3]
Q: What is the year over year effect?
Ans: The year-over-year (YoY) effect refers to the impact that comparing a metric, such as revenue or profit, between the current year and the previous year can have on the analysis and interpretation of a company’s performance.
The key aspects of the YoY effect include:
– Smoothing out seasonal variations: YoY comparisons help eliminate the impact of seasonality on a company’s results, providing a clearer picture of underlying trends.
– Identifying long-term growth patterns: YoY analysis allows for the detection of sustained growth or decline over a 12-month period, rather than just short-term fluctuations.
– Providing context for performance: YoY comparisons give stakeholders a better understanding of a company’s progress and trajectory compared to the prior year.
– Enabling benchmarking: YoY growth rates can be compared to industry averages, competitors, or the company’s own historical performance.
Overall, the YoY effect helps analysts and decision-makers gain meaningful insights into a company’s financial health and growth potential.[5]
Q: What is the difference between Yoy and MoM?
Ans: The key difference between year-over-year (YoY) and month-over-month (MoM) is the time period being compared:
YoY compares the current year’s value to the same period (month, quarter, etc.) in the previous year.
MoM compares the current month’s value to the previous month’s value.
YoY analysis provides a longer-term perspective on performance trends and growth, while smoothing out seasonal variations. MoM analysis offers a more granular, short-term view of changes, but can be more volatile due to seasonality and other factors.[3][4][5]
Q: How to evaluate the financial performance of a company?

Q: What is a good yoy growth rate?
Ans: There is no single definition of a “good” year-over-year (YoY) growth rate, as it can vary depending on the industry, company, and specific metric being analyzed. However, some general guidelines:
– YoY growth above 10-15% is often considered strong
– YoY growth between 5-10% may be seen as moderate
– YoY growth below 5% could be viewed as weak
The “good” level of YoY growth also depends on the company’s historical performance, future goals, and competitive landscape. Consistent, sustainable growth is generally more desirable than volatile, short-term spikes.
Ultimately, the appropriate YoY growth rate will depend on the context and expectations for the particular company or industry. The key is to analyze the YoY growth trend over time and compare it to relevant benchmarks.[3][4]
Q: What is MoM in finance?
Ans: MoM in finance stands for “month-over-month”. It refers to a comparison of a financial metric, such as revenue or profit, between the current month and the previous month. MoM analysis provides a more granular, short-term view of changes in a company’s performance, in contrast to the longer-term, year-over-year (YoY) analysis.[3][4][5]
Q: What is the base effect of the year-over-year?
Ans: The base effect in year-over-year (YoY) analysis refers to the impact that the previous year’s value has on the current year’s YoY growth rate.
If the previous year’s value was unusually low or high, it can skew the YoY growth rate in the current year, making it appear higher or lower than the actual underlying performance.
For example, if a company’s revenue was $100
