IT Spending as a Percentage of Revenue by Industry, Company Size, and Region

January, 2021

IT spending as a percentage of revenue is a key metric that most organizations use to calculate their IT spending levels. The formula is simple: It is the company’s IT operational spending (including depreciation) divided by the firm’s total revenue. The calculator can also be set up on a cash basis by using total IT spending, including capital spending, and omitting depreciation. Although the calculation is straightforward, it is essential to understand how this metric varies by industry, company size, and region.

This Research Byte analyzes IT spending as a percentage by industry, IT costs as a percentage of revenue by company size, and IT budgets as a percentage of revenue by region. We discuss why it is better to evaluate percentiles rather than average IT spending. Finally, we outline other key metrics for IT budget analysis, such as IT spending per employee, IT spending per user, and IT spending per desktop.

IT Spending as a Percentage of Revenue by Industry

IT spending as a percentage of revenue is the most popular formula to use in calculating overall IT spending. One reason for this is that financial executives are accustomed to looking at many business functions in terms of a percentage of revenue. For example, they look at sales expense, marketing expense, and accounting costs all calculated as a percentage of revenue. Computing this metric for information technology is a logical extension.

In considering IT spending as a percentage of revenue, the first important principle is that this metric varies greatly by industry. As shown in Figure 1, IT spending as a percentage of revenue in the financial services industry ranges between 4.4% at the 25th percentile to 11.4% at the 75th percentile. In contrast, discrete manufacturing companies spend 1.4% and 3.2% at the 25th and 75th quartiles, respectively. To put this in sharper relief, a financial services organization at the 25th percentile spends more than a discrete manufacturer at the 75th percentile.

There is no factor more important in the formula for IT spending as a percentage of revenue than industry sector—not company size, not geographic location.

Notice, also, in Figure 1, we are tracking IT spending metrics against industry percentiles, not against industry averages. Average IT spending tends to be much greater than the median. In fact, we often see average IT spending as a percentage of revenue that is actually equal to or higher than the 75th percentile! This is because IT spending is not a normal distribution but rather is skewed toward higher quartiles. This makes sense when you consider that no organization can have IT spending that is less than zero—but there is no limit to how much you can spend. For this reason, we publish all of our IT spending ratios at the median, 25th percentile, and 75th percentile. This encompasses the middle 50% of the sample, thus excluding outliers on either side.

Our benchmarks report provides benchmarks for over 25 industry sectors, including manufacturing, banking and finance, insurance, retail, wholesale distribution, energy and utilities, healthcare, professional services, transportation and logistics, construction and trade services, IT services, government, nonprofit and charitable organizations, higher education, commercial real estate, high-tech, food and beverage, industrial and automotive, commercial banking, online retail and e-commerce, hospitals, city and county government, government agencies, and logistics.

IT Spending as a Percentage of Revenue by Company Size

Our research shows that IT spending as a percentage of revenue does vary by organization size, with larger companies within an industry tending to spend more on IT as a percentage of revenue than smaller companies. However, the effect of organization size is far less than the deviation by industry sector. For example, a small bank will spend much more on IT as a percentage of revenue than a large construction company. In fact, the small bank might easily spend over 10% of its revenue on IT, whereas a large construction firm would be unusual if it spent more than 2%.

Therefore, when benchmarking IT spending as a percentage of revenue, look primarily at your industry sector. Then look to see whether your organization size is much greater or less than the demographics of the survey sample. You may be able use this in your analysis to justify a greater or lesser level of IT expenses.

IT Spending as a Percentage of Revenue by Region

Within the U.S. and Canada, our research does not show any difference in IT spending as a percentage of revenue between geographic regions. For example, a midsize manufacturing company in California the West Coast of the United States should not be spending differently than a similarly sized manufacturer in Texas, New York, Florida, or Montreal, Canada. We do not recommend, therefore, that IT organizations attempt to segment a sample by geography. To do so only yields a smaller sample, and the confidence level will be less.

Neither do we see significant differences between North America and European countries or other developed countries. However, we do not yet have a large enough sample to draw conclusions about IT spending in developing countries, such as parts of Asia, South America, or Africa.

IT Spending per Employee, Per User, and Per Desktop PC

One mistake that IT leaders make in benchmarking their IT spending levels is only to look at their IT budgets as a percentage of revenue. To get a more complete picture, it is advisable to use other ratios as well, as shown in Figure 1. For example, look at IT spending per employee—or better yet, IT spending per user. The latter is more significant, because IT organizations must support users whether or not they are employees. Healthcare companies, for example, tend to have many more users than employees. On the other hand, in some companies, especially in manufacturing, not all employees are users of IT.

Another good benchmark is IT spending per desktop (or, per PC/laptop). This can provide another perspective in cases where users have more than one desktop/laptop, users share PCs (e.g. across multiple shifts, for example, in a hospital), or where there are a significant number of desktop computers in laboratories, classrooms, or other shared environments.
