Scenario: who actually wins?

Add utilities, food, and transport and the annual gap widens. The crossover point: you need to earn about $103,345 in San Diego to match $100,000 in Boston.
The First-Time Buyer

The Remote Worker
If your salary is locked to a national scale regardless of location, Boston is the obvious win. A $120,000 remote salary in Boston has the purchasing power of about $124,013 in San Diego. The catch: some employers use location-based pay bands, which can erase part of that advantage.
The Family of Four

After housing, the next biggest budget line is usually childcare and education - costs that vary less by city than housing does.
