Cost of living in Portland, Maine

Portland, Maine has about 68,854 people. That count is a 2020–2024 Census average, not a headcount from one day.

A typical home is worth about $489,600.

We could not match this place to a county, so there is no HUD rent on this page.

Maine's prices sit at 97.0 when the U.S. average is 100. This place is not in a metro area with its own index, so this is the state number from BEA for 2024.

Maine taxes wages. A typical combined sales tax is 5.5% as of January 1, 2026. That mix is statewide, not Portland's exact store tax.

In July 2026, a typical Maine home paid 32.41¢ per kilowatt-hour. That is a state average from EIA, not Portland's bill.

EIA does not publish a Maine gasoline price. For the week of October 12, 2026, the New England (PADD 1A) all-grades price was $4.433 a gallon. At 12,000 miles a year and 25 mpg, the index counts that as $2,127.84 a year. Those miles are our standard, not a Census figure, and every town in Maine shares this price.

Among 95 places we list in Maine with a rent figure, 12 have higher typical rent than Portland.
