## What is the Average Groceries Cost Per Month?

Definition:

The average monthly grocery bill for one person ranges from $165 to$345, depending on age. The USDA estimates that a family of two will spend between $380 and$770 per month on groceries, while a family of four can expect to pay between $640 and$1,500.

These estimates are based on what consumers in the U.S. actually pay for food at home, which the USDA reports is about 6% of income.

The median household income in the U.S. is about $63,000 per year, which means the average American spends about$450 per month on food at home.

The USDA calculates the cost of groceries based on age groups and household size. Their data shows that families with a single adult tend to have lower grocery bills than larger households; however, single adults under 31 have higher grocery expenses than older ones (likely because many younger adults live with their parents).
