There's no secret to scoring a coveted 90210 mailing address in California. All it takes is $692,388.
From Beverly Hills to Greenwich, Connecticut, personal finance website GOBankingRates determined the exact annual income needed to live comfortably in the country’s most expensive ZIP codes, based on local home values and the cost of living (including groceries, transportation, health-care costs and utilities).
The study assumes that half of that income will be spent on necessities, 20 percent put toward savings and 30 percent left for discretionary spending (otherwise known as the "50-30-20 rule").
In that case, Sagaponack, a beachfront town in the affluent Hamptons area of Long Island, New York, is the nation’s most expensive ZIP code, requiring an income of more than $850,000 to live there. Beverly Hills came in second.
Here are the top 10 ZIP codes:
Sagaponack, New York $853,738
Beverly Hills, California $692,388
Alpine, New Jersey $499,244
