A new study is revealing how much money is needed to live comfortably in Pennsylvania. The SmartAsset study considered the 50/30/20 rule, which recommends residents put 50 percent of their income towards needs like food and housing, 30 percent toward wants, and 20 percent toward debt. Based on that calculation, a family of four would need to earn about 248-thousand dollars per year in the state. A single-working adult would need to earn about 95-thousand annually to live comfortably.
