The level of income needed to afford basic expenses often exceeds the minimum wage, forcing the working poor to work multiple jobs or seek public assistance to make ends meet. Understanding the true level of income required to cover housing, food, clothing, child care, transportation and medical expenses provides a more accurate benchmark for assessing the jobs available in a region or local area. The living wage also adjusts for regional variation in costs.

In MetroWest in 2021, in a family of four with two earners, each earner would need to earn about $32.27 an hour, or about $134,200 a year combined, in order to meet the living wage level. A family of three with one earner needs an hourly wage of $58.52 to earn $121,700 a year to make ends meet. Two earners with no dependents must earn $15.89 an hour or $66,100 combined. MetroWest was slightly more expensive than the state as a whole at all family levels.

Figures are in 2021 dollars and assume a 40-hour work week. The living wage model is an alternative measure of basic needs. It is a market-based approach that draws upon geographically specific expenditure data related to a family's likely minimum food, child care, health insurance, housing, transportation, and other basic necessities (e.g. clothing, personal care items, etc.) costs.
