Charlotte, North Carolina, has become a place where a comfortable life requires a six-figure salary, according to a recent study from SmartAsset. The study’s authors used a 50/30/20 model for their calculations, in which no more than 50% of a household’s income is allocated for essentials such as housing, transportation, and groceries, 30% for “fun” things such as hobbies and entertainment, and 20% for savings, investments, and paying off debt.
