Living in Guam is generally more expensive than the U.S. national average, primarily because it is a remote island that imports over 90% of its goods, including food and fuel. In 2026, residents face high utility costs—often 2 to 3 times higher than the mainland—due to the reliance on imported oil for electricity. Groceries are also notably pricey; a gallon of milk or fresh produce can cost double what it does in California. Housing is a mixed bag: while property taxes are relatively low, the presence of a large military population (Air Force and Navy) creates high demand, keeping rental prices elevated in popular villages like Tamuning and Dededo. However, there are offsets: there is no state income tax, and the "Jones Act" shipping costs are somewhat mitigated by the lack of customs duties on most U.S. goods. For a 2026 expat, a comfortable lifestyle typically requires a higher salary than a comparable role in the mainland, as "island living" necessitates a larger budget for basic necessities and travel.
