EV vs Gas Cost Per Mile in Maryland
At Maryland's average prices, a Tesla Model 3 RWD costs an estimated $0.053 a mile to charge at home and a 30 mpg gas car $0.107 a mile in fuel: $638.00 a year apart over 12,000 miles. The EV still costs less per mile, about 50% of the gas car, but Maryland's 21.4¢/kWh rate narrows the gap.

Maryland has more plug-in cars per driver than most of the country. Its 120,500 battery-electric registrations at the close of 2025 equal 2.6% of 4,699,400 light-duty vehicles, the 9th-highest share nationwide, and the US figure is 2.1%. Plug-in hybrids add 41,500, raising the share with a charging port to 3.4%. Counted per home, the ratio is 5.3 for each hundred households, the 11th-highest, with the country at 4.6.
Public charging is sized close to that fleet. Maryland lists 5,666 public ports across 1,702 sites, the 14th-highest port count among the states, made up of 4,049 Level 2 and 1,605 DC fast units. Fast charging holds a 28% slice of that, where the nation's is 30%. Per plug, the state works out to 21.3 registered EVs, and 75 per fast unit, beside national figures of 21.7 and 72; on EVs per port it places the 14th-highest.

Worked example
Worked example: Model 3 RWD vs a 30 mpg car in Maryland
At 21.4¢/kWh, a Model 3 RWD (25 kWh per 100 miles, EPA) draws 25 kWh from the wall for every 100 miles (the EPA measures it at the wall), so each mile costs $0.053. A 30 mpg car at $3.20/gal spends $0.107 a mile. Over 12,000 miles: $642.00 for the EV, $1,280.00 for gasoline, a difference of $638.00 a year (fuel only). That gap is the 39th-highest of the 51 on this site.
What the numbers say
What the numbers say in Maryland
Here the electricity rate is the hurdle. Residential power averages 21.4¢/kWh, 18% above the US average of 18.2¢/kWh, the 15th-highest of any state, while gasoline costs $3.20/gal, in line with the US average of $3.20/gal. Charging the Tesla Model 3 RWD at home comes to $0.053 per mile; on the national rate the car would run $0.045. Electricity remains the cheaper way to cover a mile, but the saving per mile is thinner than the national rate would give.
A household rate of 42.7¢/kWh is where the EV would lose its per-mile lead over a 30 mpg car, and Maryland's average is 21.4¢/kWh; a gas model would need 60 mpg to tie at that average. Public DC fast stations, billed per kilowatt-hour, are the one setting where prices can approach that line. If you top up away from home, put the station's price in the electricity field and read what is left of the saving.
With the state's rate above the US one, the plan you are billed on counts for more than it would in a cheap-power state. An average mixes peak and off-peak hours, so ask whether your utility has a time-of-use or EV tariff and enter its overnight price.
Fuel is not the whole purchase: the car and the charger cost money too. With 41,500 plug-in hybrids already registered here, the plug-in hybrid vs EV vs gas calculator is worth a run because it adds the sticker price, and Level 2 installation cost prices the home unit. The same rate also settles gas against a heat pump on Maryland's heating page.
Questions
FAQ
Is charging an EV cheaper than gas in Maryland?
At Maryland's average prices, yes for the page's example: $0.053 a mile for a Model 3 RWD at home against $0.107 for a 30 mpg car, $638.00 a year over 12,000 miles. The EV would lose its fuel-cost edge only above about 42.7¢/kWh, or against a gas car rated above 60 mpg. Both prices are editable above.
What about public fast charging in Maryland?
Fast chargers usually charge more per kWh than a home rate. This page uses Maryland's home average, 21.4¢/kWh. To see the cost per mile on the road, type the charger's price per kWh into the electricity rate field; the gas side stays at $3.20/gal.
How do time-of-use rates change this in Maryland?
The EV's cost per mile moves in direct proportion to the rate you charge at. If an overnight rate were half of 21.4¢/kWh (10.7¢/kWh), the Model 3 RWD would cost $0.027 a mile instead of $0.053. Check your utility's tariff for the real overnight rate and type it in.
Does Maryland's high electricity rate cancel out an EV's fuel savings?
Not at the state average. At 21.4¢/kWh the Tesla Model 3 RWD spends $0.053 per mile, the 30 mpg gas car $0.107, and the two only meet at 42.7¢/kWh. Charging at home over 12,000 miles comes to $642.00 a year. A heavier vehicle draws more: the Ford F-150 Lightning on that rate costs $0.103 per mile. Your own rate, or an overnight time-of-use price, is the figure to type in.
How crowded are public chargers in Maryland?
Statewide, 21.3 registered EVs share each public port and 75 share each DC fast port; the country's averages are 21.7 and 72, which puts Maryland the 14th-highest by EVs per port. A statewide ratio cannot show which stations queue at busy hours or how far apart they are, so look at the ones you would actually use.
