In Q2'26, Microsoft's operating expenses reached $17.0B USD, with R&D expenses at $8.5B USD and SG&A expenses at $8.5B USD, reflecting a balanced contribution from both categories in the latest quarter. From Q3'23 to Q2'26, total operating expenses exhibited an overall upward trend, growing from $14.4B USD to $17.0B USD, driven by consistent increases in both R&D and SG&A components despite periodic fluctuations—such as a dip in Q1'24 and Q1'26. R&D expenses showed steady growth from $6.7B USD in Q3'23 to $8.5B USD in Q2'26, with notable accelerations in Q3'24 and Q4'25, while SG&A expenses trended higher from $7.4B USD to $8.5B USD, peaking at $9.3B USD in Q4'25 amid volatility in earlier periods. This pattern underscores Microsoft's sustained investment in innovation and administrative functions, with stacked bars highlighting R&D's growing share relative to SG&A over the nine-quarter span.
