Quarterly Revenue Growth Overview, Formula, How to Increase

calculating year over year growth

If a company reported a 35% increase in revenue in December, the data would provide less insight than a report showing that revenue increased 20% in the most recent December to December period. The latter period is a year-over-year measure that indicates revenue is growing on a yearly basis rather than just for the holiday season. Then take the difference between these two construction bookkeeping measurements and divide that by the total revenue in the last year. However, healthy year-over-year growth is usually between 15% – 25%, with higher growth rates threatening to overburden smaller businesses. A 15% year-over-year growth rate at minimum is a good goal to set because a business that grows at this rate will effectively double its revenue size in five years.

Year-over-year is a helpful calculation for businesses and investors to look at, but it shouldn’t be the only calculation they use. Sometimes, breaking down revenue or investment returns by month can be useful. A particularly strong month might be smoothed out when you’re only looking at yearly numbers. But a really bad month for the business could also be overlooked if only year-over-year measurements are used. Many government agencies report economic data using year-over-year calculations to explain economic performance over the past year.

In addition, companies without at least one year of business under their belt cannot benefit from the analysis. Because if investors compared their fourth quarter with their first , they might determine unprecedented growth when the results clearly show that one season is just busier than the other. Many organizations – including governments and businesses – love this longer-term outlook on how companies or investments perform.

The Midpoint Method is a variation of the Straight-line Percent Change Method that uses the midpoint of the two values instead of just the starting value. Its primary benefit is that it solves the end-point problem, which is inherent in the Straight-line Percent Change Method due to its reliance on the beginning value.

For instance, Company A’s earnings may grow from $100,000 per year to $150,000 per year, representing 50% growth, but only a $50,000 change. A much larger Company B’s earnings may only grow at, say, 5% a year (10× less in terms of the growth rate) but amount to several millions of dollars in the company’s coffers. Growth rates refer to the percentage change of a specific variable within a specific time period. Growth rates can be positive or negative, depending on whether the size of the variable is increasing or decreasing over time. Growth rates were first used by biologists studying population sizes, but they have since been brought into use in studying economic activity, corporate management, or investment returns.

It’s important to remember that Year Over Year growth can be a beneficial calculation for virtually any industry or use case. But, again, other timeline measurements can also be impactful in giving you a clear view of performance . Once you have that data, take your current period’s growth and subtract that same figure from the same period in the previous year. Measures growth change of a certain metric by comparing the difference in its value between two consecutive months. If we compared the retailers’ results in Q4 to Q3 in the same year, it might appear the company is undergoing unprecedented growth. Unlike standalone quarterly/monthly/weekly metrics, YOY gives you a clearer picture of performance without seasonal effects, monthly volatility, and other factors.

Straight-line Percent Change Method Example

The following example shows how to use this formula to calculate year over year growth for a company in Excel. Quarter over quarter (Q/Q) is a measure of an investment or a company’s growth from one quarter to the next. Year-over-year 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.

  • In this case, we have the same initial data set containing the year and total revenue of each year.
  • Both of them are considered powerful tools to foresee the growth percentage over several periods.
  • They usually include profits and day-to-day factors like the number of items sold in each period.
  • This calculation is fairly easy to grasp, apply, and keep track of, which explains its significant popularity in finance and other business-related fields.
  • Calculating YoY metrics is sometimes called “annualizing,” and it’s one of the best ways to develop a longer-term understanding of your business’s performance.

For example, a startup might have a growth rate of 150%, 76%, and 88% over the first couple months. But at this point, it’s too early to determine what a sustainable growth rate will be. It’s quite likely the growth rate will drop as the company matures. When measuring the Revenue Growth Rate, calculate a longer trend (12-18 months) to ensure your percentages reflect an accurate trend and not a one-time exponential growth curve. I outlined the fundamentals of discovering your current revenue growth rate and provided a straightforward google sheet to help you get started.

How do you calculate year-over-year growth?

  1. Take your current month's growth number and subtract the same measure realized 12 months before.
  2. Next, take the difference and divide it by the prior year's total number.
  3. Multiply it by 100 to convert this growth rate into a percentage rate.
