San Jose, CA Cost of Living (2026)

San Jose has a cost of living index of 172, making it one of the most expensive cities in the country, slightly higher than San Francisco on the overall index. Housing is the dominant factor at an index of 310. A mortgage or rent payment that would be $1,500 a month at the national average translates to roughly $4,650 in San Jose. The median household income is around $148,000, which is high by any national measure, but housing costs absorb a disproportionate share of that.

The city sits at the center of Silicon Valley, and the high incomes are concentrated in tech. Engineers and product managers at large companies frequently earn $200,000 or more in total compensation, but that income does not make the housing market easy. A median single-family home in San Jose regularly trades above $1.4 million. At a 7% mortgage rate, the monthly payment on that with 20% down exceeds $7,500 before taxes and insurance.

For someone moving from a city with an average cost of living, a $100,000 salary there is equivalent to about $58,000 worth of purchasing power in San Jose. The difference is substantial enough that relocation offers should account for it explicitly. Groceries run moderately above average, and healthcare costs are also elevated, but neither comes close to the housing premium.

One practical note: many San Jose residents commute to jobs in San Francisco, Palo Alto, or the broader peninsula. The distance is manageable by freeway, but Bay Area traffic can make a 25-mile commute take over an hour each way. Some residents trade a slightly longer commute for meaningfully lower rent by living farther south in cities like Morgan Hill or Gilroy.
