About Gas Prices in Massachusetts

The gasoline price shown above represents the weekly retail average for Massachusetts, collected by the U.S. Energy Information Administration (EIA) as part of their Weekly Retail Gasoline and Diesel Prices survey. Prices are expressed in US dollars per gallon and include all taxes.

Gas prices in Massachusetts can vary by region, grade of fuel, and proximity to supply infrastructure. The figure shown is the statewide weekly average. California, Hawaii, and states in the Northwest typically see higher prices due to transportation costs and state fuel taxes.

What affects gas prices?

Retail gasoline prices are primarily driven by crude oil costs (about 50% of the price), refining costs and profits, distribution and marketing, and federal and state taxes. State taxes vary significantly — some states charge over $0.60/gallon in combined taxes while others charge under $0.20/gallon.

Frequently Asked Questions

Why are gas prices different in Massachusetts vs other states?▾
Gas prices vary by state due to differences in state fuel taxes, proximity to refineries, pipeline infrastructure, local environmental regulations (like California's CARB fuel requirements), and regional supply/demand dynamics.

When is the cheapest time to buy gas?▾
Studies show gas is often cheapest on Monday or Tuesday mornings. Prices tend to rise toward the weekend as demand increases. Seasonally, prices are usually lower in late winter (January-February) before summer blend requirements kick in around March-April.
What makes up the price of gasoline?▾
The retail price of gasoline includes: crude oil cost (~54%), refining (~14%), distribution and marketing (~14%), and taxes (~18%). Federal excise tax is fixed at 18.4 cents/gallon; state taxes range from about 14 cents (Alaska) to over 68 cents (California) per gallon.
How often does EIA update gas price data?▾
The EIA publishes weekly retail gasoline prices every Monday for the previous week. Data is collected through a survey of retail outlets across all 50 states plus D.C. The survey covers all grades and formulations of gasoline.
