Cost of Living in California for a Family of Four (2026)
A family of four in California needs about $9,251 a month ($111,016 a year) to cover a typical household budget before saving. That is 19% above the U.S. average of $7,777 and ranks #2 of 51, where #1 is the most expensive.
Rent is the main reason it costs more. California's rent level is 154% of the national average, so a typical three-bedroom rental with utilities runs about $3,133 a month, compared with $2,030 nationally. Everyday goods such as groceries and clothing cost 6% more than the national average, which puts this family's grocery bill at about $1,106 a month on the USDA low-cost food plan.
To cover this budget and still save 15% of take-home pay, a family would need about $10,884 a month after taxes ($130,607 a year).
