About Gas Prices in South Carolina
The U.S. Energy Information Administration (EIA) surveys fuel retailers weekly but doesn't publish a separate price for South Carolina, so the price shown is the EIA's Lower Atlantic regional average for regular unleaded gasoline. Prices at individual stations in South Carolina may be higher or lower depending on location, brand, and local competition.
Several factors influence South Carolina's gas price: state fuel taxes, the distance from major refineries, pipeline and distribution infrastructure, and the required seasonal fuel blend. Use the calculator above to see exactly how today's South Carolina price affects your commute, road trip, or monthly driving budget.
South Carolina Fuel Taxes: ≈29¢/gal
South Carolina has a state gas tax below the national average, though it's been rising every year. South Carolina's state gas tax is about 29 cents per gallon, below the roughly 33.5-cent national average. The rate has been climbing steadily since a 2017 law began phasing in gradual annual increases to fund road and bridge repairs, and it continues to rise a few cents at a time.
Tax figures are approximate state-level taxes and fees per gallon of regular gasoline and exclude the 18.4¢/gal federal excise tax. Rates change, so verify current rates with the state's revenue or transportation department.
How South Carolina Gets Its Gasoline
South Carolina has no oil refineries, but it sits directly on the Colonial Pipeline's mainline, which carries gasoline and diesel from the Gulf Coast to the East Coast and maintains a distribution terminal in the Upstate region. That direct pipeline access is South Carolina's main supply advantage.
Where Gas Is Cheapest and Most Expensive in South Carolina
The Upstate, around Spartanburg and Greenville, closest to the Colonial Pipeline terminal, typically has the state's lowest prices. Coastal tourist areas like Myrtle Beach and Hilton Head often run a bit higher during peak travel season.
