Cost of Living in San Diego: Where the Money Goes

Living in San Diego costs more than in most of the country, and housing is the main reason. According to the Bureau of Labor Statistics, housing took 37.4% of the average San Diego-area household's spending in 2023-24, compared with 33.2% nationally. Transportation also runs above the national share. Food and health care, as a share of the budget, come in below it.

In dollars, the same federal survey found that households in the San Diego-Carlsbad metro area, which covers all of San Diego County, spent an average of $108,694 per year. That figure is an average across all kinds of households, from single renters to large families, so treat it as a reference point rather than a target. The sections below break it down.

Where the numbers come from

Two federal sources do most of the work here, and both are free to look up.

The BLS Consumer Expenditure Survey reports what households in the San Diego area actually spend, by category. The most recent San Diego release, published in January 2026, covers 2023-24. The Census Bureau's QuickFacts for San Diego County draws on the American Community Survey and gives medians for income, rent and home values over 2020-2024.

Neither source tells you what your own rent will be on a given street. They do tell you the shape of a typical budget, and that shape is fairly stable from year to year.

The budget at a glance

Here is how San Diego households split their spending compared with the rest of the country, per the BLS 2023-24 release.

A lower share doesn't always mean cheaper groceries or doctor visits. It can just mean housing takes such a big bite that everything else shrinks in proportion. Read the table as "where the money goes," not as a price list.

Housing: the line that sets everything else

Census QuickFacts lists a median gross rent of $2,246 for San Diego County over 2020-2024. Gross rent includes an estimate of utilities the renter pays, so it's closer to your real monthly housing cost than an advertised rent. The median value of owner-occupied homes is $854,700, and 54.6% of housing units are owner-occupied.

Put those next to the county's median household income of $106,268 (in 2024 dollars) and the math is simple. A year at the median gross rent comes to about $26,950, roughly a quarter of the median income before taxes. Half of households earn less than the median, and many of them pay more than the median rent, so for a lot of people the share is much higher.

Rents also vary sharply across the county. Coastal neighborhoods and areas close to downtown job centers usually cost more than inland and South Bay communities. If you're comparing areas, our North Park guide describes one of the central neighborhoods many renters look at first, and the Living in San Diego section collects our other guides on everyday costs and household topics.

Renting versus buying

Buying here usually means a large down payment and a mortgage sized to that $854,700 median value, plus property tax and insurance. Renting keeps more cash free but leaves you exposed to increases at renewal. This guide can't tell you which is right for you. A HUD-approved housing counselor or a licensed financial professional can look at your actual numbers.

Transportation: the second-biggest line

At 18.1% of spending, getting around costs San Diego households more than the national average share. Much of the county was built around the car, distances are long, and many people commute from where housing is cheaper to where jobs are.

Transit can cut that line for some households. The MTS Trolley and bus network covers the urban core and several South Bay and East County cities; our San Diego Trolley guide explains the lines and how fares work. One concrete saving for families: under the Youth Opportunity Pass program sponsored by SANDAG and the County, riders 18 and under ride MTS and NCTD services free with a Youth PRONTO card or app account. MTS lists the program as running through June 30, 2027.

If you drive, fuel, insurance and parking all add up. Prices for those change too often to quote here, so check current numbers before you commit to a long commute.

Food, health care and the rest

Food took 11.2% of San Diego-area spending in 2023-24, below the U.S. share of 12.9%. Farmers markets, warehouse stores and cooking at home all help, but the main thing pushing the share down is how much housing costs, not cheap food.

Health care took 6.8%, under the national 8.0%. That number depends heavily on whether an employer covers most of your premium. If you're buying coverage on your own, Covered California is the state's official marketplace. For anything about your specific plan, talk to the insurer or a licensed agent.

Utilities and water

Electricity and gas come from SDG&E for most of the county, and bills depend on your rate plan, the season and how much you cool or heat. Water is billed by your local water agency, not by one countywide utility. Our guide to water-use rules in San Diego County explains how to find your water provider and what rules apply. For rate details, go to the utility's own published tariffs instead of an estimate from a third party.

Sales tax

Sales tax in California varies by address because cities and districts add their own rates on top of the state rate. The California Department of Tax and Fee Administration publishes current rates and an address lookup.

Ways people make the numbers work

None of these are tricks. They're the ordinary trade-offs San Diegans make.

• Living inland or in the South Bay and commuting, ideally along a Trolley or COASTER line.
• Sharing housing, especially in the first year after moving.
• Dropping a second car where transit or a bike can cover daily trips.
• Using free public options: beaches, many parks and trails, and libraries cost nothing to use. Our beach guide covers how to pick one.

Two things are worth doing before any big decision. First, compare your real offer or income against the federal figures above, not against an online "cost of living index" with no stated method. Second, price your actual housing and commute on the ground, at the time of day you'd make the trip. The federal data gives you the shape of the budget. Only your own numbers tell you whether it fits.
