The biggest line item: rent
A 1-bedroom in Boston averages $2,250/month — that's $27,000/year, or about 16% 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 $3,128/month, which comfortably covers a 1-bedroom in Boston.
Take-home reality
Your gross is $173,800, but federal taxes, FICA, and Massachusetts state taxes typically eat 25-30%. After-tax income lands around $10,428/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.
