Direct Answer
Best Buy reports revenue across 2 business segments in its fiscal 2026 Form 10-K. Domestic is the largest, with $38.3 billion of revenue (92% of the total), followed by International at $3.4 billion (8%).
How Does Best Buy Make Money?
Domestic supplies 92% of revenue, so Best Buy's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2025 and 2026, International grew fastest (+3.7%) and Domestic slowest (+0.1%), so the revenue mix tilts toward International while that gap lasts.
| Segment | FY2026 revenue | FY2025 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Domestic | $38.3 billion | $38.2 billion | 91.8% | 0.1% |
| International | $3.4 billion | $3.3 billion | 8.2% | 3.7% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Best Buy's reported revenue for fiscal 2026; 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 Best Buy reported in the segment note and revenue disclosures of its Form 10-K filed March 18, 2026 (accession 0000764478-26-000009), 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 2026; it is not a forecast or a recommendation.
