The biggest line item: rent
A 1-bedroom in San Diego averages $2,300/month — that's $27,600/year, or about 35% of the salary required for this lifestyle. Most financial planning rules suggest keeping housing under 30% of take-home pay; on this salary, your housing cap would be $1,431/month, which is tight against the typical San Diego 1-bedroom of $2,300/month.
Take-home reality
Your gross is $79,500, but federal taxes, FICA, and California state taxes typically eat 25-30%. After-tax income lands around $4,770/month — that's the number that has to cover housing, transportation, food, and savings. If that feels tight for the lifestyle you have in mind, scale up your salary target.
