I recently moved from TX to CA (Bay Area).
I had a 3k s.f. house and an all-in monthly cost of ~$2k/mo (including mortgage, insurance, pest control, etc) for household expenses.
I recently had a soft offer (verbal discussion of salary ranges) of around ~$150k to move back to TX. To match that in CA dollars, it requires ~$200k/yr+ compensation.
Method:
Use the following two tax estimators:
https://smartasset.com/taxes/texas-tax-calculator
https://smartasset.com/taxes/california-tax-calculator
...count ~$1500/mo => $20k/yr for housing in TX/Dallas, ~$3000/mo => $36k/yr for housing in Bay Area.
...count ~$12k/yr for living expenses in TX, $20k/yr for Bay Area ($1000/mo for restaurants, etc, in TX, $1500/mo in Bay Area... this accounts for increased food / restaurant / drink / entertainment / parking prices in California).
TX: $20k housing + $12k living => $36k mandatory expenses
CA: $36k housing + $20k living => $56k mandatory expenses
Include a mandatory savings rate of 50% of yearly housing costs (insulate against layoffs / economic downturns) and you're at: $46k/yr for TX and $74k/yr for CA.
An offer of $150k in TX gets you income after taxes of: ~$108k minus $46k living expenses for a savings rate of ~$62k/yr.
To get to a $62k/yr savings rate in CA, you need $62k+$74k after tax income which is $136k total. That requires an offer of ~$200k/yr in CA.
Obviously these numbers are very hand-wavy, but it is instructive to go through this exercise. Running these numbers at a more modest $100k salary in TX and keeping expenses the same (leading to a ~$12k/yr savings rate), you need ~$86k in after tax income which is a ~$130k CA salary, which is ~30% increase over a baseline $100k in TX for a transfer to make any kind of sense (plus relo expenses, one-time-costs, etc).
A $12k/yr savings rate in TX for 10 years will get you $120k and a house.
A $12k/yr savings rate in CA for 10 years will get you a down payment and nothing more (ie: you cannot live/retire where you work/earn).
