To maintain your Los Angeles purchasing power, here's what you'd need to earn in San Diego.
Los Angeles vs San Diego: which makes more sense for you?
On paper, Los Angeles's cost-of-living index of 166 runs roughly 4.2% higher than San Diego's 159. But that headline number papers over real differences in how that cost is distributed — rent might be far more expensive while groceries and transit costs run closer to even.
The rent gap
A 1-bedroom apartment in Los Angeles averages $2,500/month, vs $2,300/month in San Diego — a -$200 difference. For 2-bedrooms, the gap widens to -$300/month. Over a year, the rent difference alone is $2,400 on a 1-bed.
Income context
Median household income in Los Angeles is $65,290, while San Diego runs $69,845 (+$4,555 difference). That matters for how the cost-of-living gap actually feels day-to-day — if local salaries are also higher, the cost difference washes out partly. If local salaries lag the cost-of-living gap, your paycheck buys noticeably less.
State tax differences
Both cities are in the same state, so state income tax is identical. The cost difference is purely local — rent, transit, groceries, and lifestyle.
