Gartner survey of IT budget

According to Gartner's survey on annual IT Staffing 70% of the IT spend comes from the OPEX per annum while only 22% comes from the CAPEX.

Gartner's 2011 survey found that the average revenue to IT budget ratio for companies was 3.5% but for technology intensive industries such as financial services and software services, the ratio can range as high as 6%. Gartner has also found variations in this ratio depending on geography. In EMEA (Europe, Middle East and Africa), IT spending as a percentage of revenue is 4.4%. In North America, the figure drops to 3.5% and in Asia, the ratio is the lowest in the world at 2.9%.
