The Department of Housing and Urban Development considers households with a rent-to-income ratio of more than 30%, that is, households that spend more than 30% their income on housing, to be cost-burdened. Cost-burdened households may have less money for other necessities such as food, healthcare, or savings. When median monthly rent is more than 30% of median monthly income, it means a typical household would meet the definition of housing cost-burdened.
