How the EV vs hybrid vs gas comparison works

This calculator computes per-mile fuel costs for three drivetrains simultaneously. For the EV, we use the EPA efficiency rating in kWh/100 miles multiplied by your local electricity rate. For the hybrid and gas vehicles, we divide the gas price by each vehicle's MPG rating. CO2 emissions use the EPA standard of 8,887 grams per gallon of gasoline and 0.86 lbs of CO2 per kWh of grid electricity (the U.S. average).

Where hybrids fit in

Hybrids occupy the middle ground between gas and electric. A typical hybrid achieves 45 to 60 MPG by combining a small gas engine with an electric motor and regenerative braking. This nearly doubles the fuel efficiency of a standard gas car without requiring any charging infrastructure. However, hybrids still burn gasoline, so their fuel costs and emissions remain higher than a fully electric vehicle.

Total cost of ownership factors not shown

• Purchase price: EVs have a higher MSRP but federal tax credits up to $7,500 can close the gap. Hybrids are typically priced between gas and EV models.
• Maintenance: EVs have the lowest maintenance costs (no oil changes, fewer brake replacements). Hybrids save somewhat on brakes but still need oil changes. Gas cars have the highest ongoing maintenance.
• Insurance: EV insurance runs 10 to 15% higher than gas or hybrid due to higher repair costs for battery and electronics.
• Resale value: EVs are depreciating faster than hybrids in the current market, though this gap is narrowing as battery technology improves.

Choosing the right drivetrain

If you have home charging access and drive under 250 miles per day, an EV will save you the most money on fuel. If you regularly take long road trips or lack charging access, a hybrid offers significant savings over gas with zero charging requirements. Gas vehicles make the most financial sense only when purchase price is the primary concern and annual mileage is low.
