Microsoft Extended Server Useful Life From 4 to 6 Years. Here's What It Did to Margins.

Key Points

• Useful Life Assumptions for Server and Network Equipment (FY24–FY26):
  • As of FY2026, Microsoft discloses:
    "The estimated useful lives of our property and equipment are generally as follows: software developed or acquired for internal use, three years; servers and network equipment, two to six years; buildings and improvements, five to 15 years; leasehold improvements, three to 15 years; and furniture and equipment, one to 10 years. Land is not depreciated."
  • The useful life for servers and network equipment is two to six years in FY2026.
  • This is unchanged from FY2025 and FY2024.
• Change in Useful Life Assumptions Over Last Three Years:
  • The last change occurred in FY2023 (effective July 2022), when Microsoft increased the estimated useful lives of both server and network equipment from four years to six years.
  • Disclosure (FY2024 10-K):
    "In July 2022, we completed an assessment of the useful lives of our server and network equipment. Due to investments in software that increased efficiencies in how we operate our server and network equipment, as well as advances in technology, we determined we should increase the estimated useful lives of both server and network equipment from four years to six years. This change in accounting estimate was effective beginning fiscal year 2023."
• Quantified Effect on Operating Income:
  • The effect of this change was disclosed in FY2023 and FY2024 filings:
    • FY2024 10-K:
      "Excluding the impact of the change in accounting estimate for the useful lives of our server and network equipment, gross margin percentage increased 2 points driven by improvement in More Personal Computing."
    • FY2024 10-K:
      "Microsoft Cloud gross margin percentage decreased slightly to 71%. Excluding the impact of the change in accounting estimate, Microsoft Cloud gross margin percentage increased slightly..."
    • The company does not provide a specific dollar impact for FY2024 or FY2025, but in FY2023, the impact was material enough to be called out in the gross margin discussion.
    • No further changes or incremental effects were disclosed in FY2025 or FY2026.

Summary of Disclosures

• FY2026:
  "The estimated useful lives of our property and equipment are generally as follows: ... servers and network equipment, two to six years ..."
  No change from prior year; no incremental effect disclosed.
