Is food expensive in Guam?

Food in Guam runs 20 to 40 percent above mainland US averages, driven almost entirely by import costs. Nearly all packaged groceries, dairy, fresh produce, and meat arrive by ship or air, so a gallon of milk often runs $7 to $9, a dozen eggs $5 to $7, and basic produce 30 to 50 percent above mainland prices. Costco in Tamuning offsets some of this for bulk shoppers, and on-base commissaries provide cheaper options for military families. Local fish and tropical fruit from roadside vendors are the affordable side of the equation. The grocery premium is the main reason Guam’s moderate lifestyle benchmark ($3,525 per person per month) matches the US average ($3,525) despite cheaper labour costs.
