The simple version

The U.S. average price of regular gasoline was $4.49 a gallon on May 19, 2026, per the Energy Information Administration. That is the number American drivers are filling up against this Memorial Day weekend. For a family driving 1,200 miles round trip to visit relatives or get to a beach, the fuel cost of the trip sits north of $215 at that average price.

This is not a piece about whether to take the trip. It is about reading the receipt. Knowing the fuel-cost line on a single trip is half of it. Knowing what those weekend drives add up to across a year is the other half, and it is the number most people never total.

The numbers

• U.S. regular gasoline retail average, week ending May 19, 2026: $4.49 per gallon (EIA Gasoline and Diesel Fuel Update).
• U.S. on-highway diesel retail average, same release: $5.60 per gallon (EIA).
• U.S. regular gasoline retail average, week ending May 24, 2021 (Memorial Day weekend, five years ago): $3.04 per gallon (EIA Weekly Retail Gasoline Prices historical series).
• Real-world new-vehicle average fuel economy for model year 2023, the most recent final EPA figure: 27.1 miles per gallon (EPA Automotive Trends Report, 2025 release).
• Next scheduled EIA gasoline release: May 27, 2026.

The math on the trip

The on-road fleet average is lower than the new-vehicle average because the fleet includes older, less efficient cars. The math below uses 25 mpg as an illustrative middle case. Plug in the figure for the actual vehicle leaving the driveway and the answer shifts.

• 1,200 miles round trip.
• 25 miles per gallon combined.
• 48 gallons of fuel.
• 48 gallons at $4.49 per gallon equals $215.52.

A more fuel-efficient car gets the number down. A 35 mpg sedan uses about 34 gallons for the same trip, roughly $153 in fuel. An older SUV at 18 mpg uses about 67 gallons, roughly $301. The same 1,200 miles can vary by $150 in fuel cost based on which vehicle leaves the driveway.

The Real Cost lens

Stretch the math from one weekend to one year. A vehicle putting on 12,000 annual miles at 25 mpg combined uses 480 gallons of fuel. At $4.49 per gallon, that is about $2,155 in annual fuel cost. At the EIA's verified May 2021 average of $3.04 per gallon, the same 480 gallons would have cost about $1,459. The annual delta on one vehicle, holding mileage constant, is roughly $696.

Across 10 years at the current price, that vehicle burns through about $21,552 in fuel. At the 2021 price, the same 10 years cost about $14,592. The difference is roughly $6,960 in fuel alone, on a single car, over a single decade. That number is real money and worth seeing as a single line, not 48 hidden gallons at a time.

What this means

Two practical reads from the EIA number. First, the gas budget for the holiday weekend is a known quantity, not a surprise. For 1,200 miles in a 25 mpg car, $215 in fuel is the floor, before tolls, lodging, food, or any premium-grade requirement. Second, the bigger story is the annual figure. Anyone reviewing a household budget who looks at the credit card line item labeled 'Gas' without comparing it to the year-prior or five-year-prior total is missing the trend. The number is up, broadly, and durably.

What this is NOT

Not a prediction about where gasoline prices go from here. Not a recommendation to buy or sell oil, gasoline futures, or any energy stock. Not advice to take or skip a Memorial Day trip. Not a political position on energy policy. Just the math on a single weekend's drive at the EIA's most recent published number.
