Microsoft growth & profitability
Planning question: how do segment growth and cost assumptions change operating profit?
What the historical analysis shows
Intelligent Cloud contributed 62.9% of the FY2026 revenue increase. Its cost-of-revenue ratio rose 4.2 percentage points. Productivity and Business Processes had a 59.9% operating margin. Segment mix and cost behavior therefore matter alongside headline growth.
How the model works
Forecast each segment from FY2026. Apply revenue growth, a change in cost of revenue/revenue, and independent operating-expense growth. Subtract both cost categories to calculate operating income. Sum segment results. Historical inputs reconcile to consolidated controls with zero differences.
Base assumptions and uncertainty
- Productivity: 15% revenue growth, flat cost ratio, and 8% operating-expense growth.
- Intelligent Cloud: 25% revenue growth, +1 percentage point in cost ratio, and 10% expense growth.
- Personal Computing: flat revenue and cost ratio, with 3% expense growth.
Downside and Upside use separate editable assumptions. The sensitivity grid tests 25 combinations of Cloud growth and cost ratios through the same model. At Base Cloud revenue, a +1 point cost-ratio shock reduces consolidated operating income by approximately $1.7B, holding other inputs fixed.
Planning recommendation
Review Cloud revenue growth and delivery-cost ratios together. Investigate cost-ratio increases before assuming faster revenue growth will translate proportionately into profit. Refresh the assumptions against subsequent quarterly disclosures before using the model for a current outlook.
Scope and limitations
Independent annual planning exercise using FY2024–FY2026 actuals from one reporting basis. Cutoff: June 30, 2026. Subsequent results are excluded. Estimates are illustrative, not Microsoft guidance. No valuation, cash-flow, tax, FX, or Azure-only forecast is modeled.
