Tesla’s official website, data suggests the average charging cost per mile is 4.56 cents, much lower than the cost per mile for gasoline. However, NRG Clean Power notes that EVs lose up to 10% of energy per charge, and it’s best to keep them plugged in during long periods of nonuse.
Superchargers can cost between 24 and 48 cents per kWh, depending on the location and time of day. Installing an at-home charger—priced between $300 and $650 (plus installation)—can help reduce these long-term costs.
Typical Nissan Sentra Fuel Costs
According to Nissan’s official site, the 2025 Nissan Sentra offers between 30 and 40 miles per gallon (MPG), depending on the model. Based on a national average gas price of $3.188 (as of Sept. 12, 2025), driving 1,123 miles a month would consume about 33 gallons of fuel, costing approximately $105 per month.
Fuel costs vary significantly by region. Drivers on the West Coast and in Alaska pay much more, while those in the Southeast benefit from some of the lowest gas prices in the nation.
Comparing Overall Costs and Ownership
When comparing monthly energy costs alone, a Tesla could cost $33–$54 per month to charge, while a Nissan Sentra costs closer to $105 per month to refuel—an estimated savings of $51–$72 monthly.
