Without a budget — or come to think of it, even with one — you may wonder how your average monthly expenses compare with "what's normal."

The average monthly expenses reported here are from the 2019 Consumer Expenditure Survey conducted by the U.S. Bureau of Labor Statistics and released in September 2020 — the latest data available. Family size doesn't necessarily mean two parents and children. A household might have any number of configurations among parents, grandparents, children and unrelated people living together.

Average monthly expenses that increased year over year

Eight out of 10 of the largest categories of average monthly expenses rose in 2019, according to the BLS report. In order of percent increases, they included:

  • Vehicle purchases (+10.5%).

  • Cash contributions (+5.7%). The category includes gifts, donations, alimony and child support, among other cash expenses.

  • Health care (+4.5%). Health insurance accounted for much of this increase.

  • Housing expenses for rented dwellings (+4.3%).

  • Food at home (+4%).

Average monthly expenses that declined

Spending on entertainment declined across all household categories, except the highest-income quintile, the BLS says. A slight decrease in spending on personal insurance and pensions, including Social Security, was also reported.

Spending in the overarching "all other expenditures" category was also down by nearly 7%.

Your average may vary

With all of the variables, stacking your family's spending up to other similarly sized households in the U.S. will be a rough comparison at best.

Spending can be impacted by income, the cost of living in your area, your family's health care needs, transportation, debt and taxes.

But looking at averages can give you an indication of whether your household spending has sprung a significant leak. If so, look for ways to patch the holes draining your cash flow.
