How Does CDW Corporation Make Money?
No single line supplies a majority of revenue: the largest, Corporate Segment Private Sector Business, is 42%, which spreads CDW Corporation's exposure across several demand drivers. Between fiscal 2024 and 2025, Small Business grew fastest (+13.3%) and Public Segment Government Agencies Education and Healthcare slowest (+4.6%), so the revenue mix tilts toward Small Business while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Corporate Segment Private Sector Business | $9.4 billion | $8.8 billion | 42.1% | 6.8% |
| Public Segment Government Agencies Education and Healthcare | $8.5 billion | $8.2 billion | 38.1% | 4.6% |
| All Other | $2.7 billion | $2.5 billion | 12.1% | 9.7% |
| Small Business | $1.7 billion | $1.5 billion | 7.7% | 13.3% |
Which CDW Corporation Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Corporate Segment Private Sector Business | $889 million | 9.4% |
| Public Segment Government Agencies Education and Healthcare | $750 million | 8.8% |
| All Other | $154 million | 5.7% |
| Small Business | $203 million | 11.8% |
Segment operating income is the profit measure CDW Corporation reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within CDW Corporation more safely than against another company.
Where Does CDW Corporation's Revenue Come From?
Regions follow the definitions in the filing; most companies assign revenue by customer location.
| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| United States | $19.6 billion | $18.5 billion | 87.5% | 6.3% |
| Outside the United States | $2.8 billion | $2.5 billion | 12.5% | 10.3% |
What the Segment Figures Do Not Show
The rows above add up to 100% of CDW Corporation's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value CDW Corporation reported in the segment note and revenue disclosures of its Form 10-K filed February 20, 2026 (accession 0001402057-26-000011), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
