Cost of Living in San Diego, CA
Weighing an offer or a move to San Diego? Enter an amount from another city and see what it takes to maintain the same lifestyle here.
San Diego carries an estimated cost of living index of 148 — nearly 50% above the US national average — making it one of the priciest large metros in the country. Housing is the overwhelming driver: the city is hemmed in by the Pacific coastline, mountains to the east, and the international border to the south, which leaves little room for new supply even as demand keeps climbing. That demand comes from a mix of a large active-duty and veteran military population, a fast-growing biotech and life sciences cluster around Torrey Pines and Sorrento Valley, and a broader tech sector drawing talent from across the country. Most residents still rely on cars for daily commuting, though the city has been steadily expanding its trolley and rapid bus network. On top of the raw cost of living index, California's state income tax — among the highest in the nation at up to 13.3% for top earners — adds a further squeeze that isn't captured in general cost comparisons, making San Diego a materially more expensive relocation than the headline index alone suggests for higher earners. Use the calculator below to translate a salary or budget figure from wherever you're comparing into a rough San Diego equivalent, and check the linked California salary and tax calculator to estimate take-home pay.

Frequently Asked Questions
What is San Diego's cost of living index? +
San Diego has an estimated cost of living index of about 148, meaning overall costs run roughly 48% above the US national average of 100. Housing is by far the dominant factor, as coastal supply constraints keep both home prices and rents elevated across the metro.
Why is housing so expensive in San Diego? +
San Diego is geographically boxed in by the ocean, mountains, and Mexican border, which sharply limits new housing supply. Strong demand from the military, biotech, and tech sectors, combined with strict local zoning and coastal development rules, keeps upward pressure on both purchase prices and rents.
Does California's state income tax add to San Diego's cost of living? +
Yes. California has one of the highest state income tax rates in the country, topping out at 13.3% for the highest earners. That tax burden isn't fully captured in a general cost of living index, so high earners moving to San Diego should factor it in separately.
Is San Diego cheaper than San Francisco or Los Angeles? +
San Diego is generally somewhat less expensive than the San Francisco Bay Area, though it can be comparable to or pricier than parts of Los Angeles depending on the neighborhood. All three remain well above the national average, driven primarily by California's tight coastal housing markets.
Is this San Diego cost of living calculator accurate for my exact budget? +
The calculator gives an illustrative estimate based on a single composite index, not a personalized budget. Real costs vary by neighborhood, household size, and lifestyle, so treat the result as a starting point rather than a precise financial figure.
