San Jose vs San Diego Cost of Living Comparison
San Diego is about 11% cheaper than San Jose overall in 2026. A single professional spends about $4,565 per month in San Jose and $4,075 in San Diego, all-in with centre rent – and to match the lifestyle a $100,000 salary buys in San Jose, you would need roughly $89,800 in San Diego.
The biggest lever is housing: a one-bedroom in the centre runs $3,300 in San Jose versus $2,900 in San Diego (-12%). Day-to-day costs differ less – groceries ($580 vs $560), utilities ($230 vs $190), and a transit pass ($90 vs $72) – which is why flat CPI comparisons mislead people who rent in the centre.

How the San Jose → San Diego salary equivalence works
MovingCal scores every city on a composite 2026 cost index that includes rent (New York = 100). San Jose scores 88; San Diego scores 79. Equivalent salary is your current salary multiplied by 79/88 – so $100,000 in San Jose ≈ $89,800 in San Diego.
Index math is a starting point, not a verdict. Two corrections matter: taxes (gross pay buys different net pay – check the salary after tax calculator for both locations) and housing choice (renting outside the centre cuts the gap to $400/month between these two cities).
