California is home to more than 4.3 million small businesses, and over 4 percent of these are in the metropolitan San Jose area. Small businesses accounted for 37 percent of employment in the San Jose area, with the largest number of employees in the professional, scientific, and technical services industry (U.S. Small Business Administration 2025b, 2025c).
We analyzed 2.1 million small businesses with Chase Business Banking accounts operating during 2025, including more than 16,000 in the San Jose metro area, to provide a snapshot of their financial health. The typical small business in San Jose exhibits financial health measures—over 23 cash buffer days and $168,200 in annual revenues—that are more robust than those of a typical small business in the U.S. Median San Jose revenues were higher than the overall sample in every industry except wholesale trade, with professional services—the largest small business sector in San Jose—having 30 percent higher revenues.
Much like our earlier snapshot on San Francisco, higher revenues in San Jose may reflect the region's higher cost of living, but cash buffer days scale balances by average outflows, suggesting that small businesses in San Jose hold relatively larger cash reserves even after accounting for their higher outflows.
Cash buffer days: Small businesses may differ along many dimensions, such as size, industry, location, and growth trajectories, but they all need to manage their cash flows. Cash reserves can be used not only to absorb unexpected shortfalls in revenue or increases in expenses but also to invest in growth opportunities. We use cash buffer days to measure how long a small business could maintain its average outflows in the event of a complete disruption to inflows.
