Santa Monica, California

The average monthly rent in Santa Monica is $3,495 and the median home value is $1,685,560. However, if you live in the prime neighborhood north of Montana, the median home value is $4,965,225.

Drivers pay an average of $4,201 annually for full coverage car insurance, according to Insure —and that doesn’t include the price of gas being stuck in traffic for hours. Travel adds another expense to the mix, with domestic fares averaging $459.79 in the first quarter of 2026 before fare increases, according to the Bureau of Transportation Statistics (BTS). This doesn’t consider international flights, which are much higher. With all these costs, a $120,000 salary leans toward the middle class.
San Francisco
San Francisco offers high salaries but some of the steepest recurring costs in housing, insurance and travel. The average monthly rent for someone living in the city is $4,500.

Before parking, healthcare, utilities, entertainment and other costs, a high salary can feel less affluent here than in other cities.
Boston
With Boston’s prestigious universities, hospitals, financial corporations and biotech firms, this coastal city draws well-paid professionals. However, earning a high salary doesn’t eliminate the city’s elevated living expenses.

Car insurance in ‘Beantown’ average $2,937 and domestic flights from average $419.73, per Insure. However, if you’re willing to drive one hour and 49 minutes, you can find fares averaging $399.56 at Bradley Airport in Hartford, Connecticut.
Per The Hill, earning a salary of $120,000 can appear upper class, but after factoring in expenses, it can make living in a coastal city feel closer to the middle.
