EV vs Gas Cost

You Save With EV Per Year$875.29
Gas $ / Mile$0.120
EV $ / Mile$0.047
Cheaper By61%
Gas / Year$1,440.00
EV / Year$564.71
Per 100 Mi: Gas vs EV$12.00 vs $4.71

Gas $/mi = Price ÷ MPG • EV $/mi = Electricity Price ÷ mi-per-kWh • Fuel/energy only.

How the Comparison Works

Both drivetrains reduce to one honest number — energy cost per mile. For gas: price per gallon ÷ MPG. For electric: price per kWh ÷ miles per kWh (most EVs manage roughly 3–4 mi/kWh). Multiply by your yearly miles for the yearly picture.

Gas $/mi = Price ÷ MPG  •  EV $/mi = $/kWh ÷ mi/kWh

Worked Example

A 30 MPG car on $3.60 gas pays $0.120 per mile. An EV doing 3.4 mi/kWh on $0.16 electricity pays $0.047 per mile — about 61% less. Over 12,000 miles a year that is $1,440.00 vs $564.71: an $875.29 yearly saving on energy alone.

What This Comparison Leaves Out

Purchase price, insurance, maintenance (usually lower for EVs: no oil, fewer moving parts), tires, home-charger installation and public fast-charging prices (often 2–3× home electricity rates) all move the real answer. This tool isolates the energy cost per mile — the figure that repeats every single day you drive. For the gas side in depth, use our cost per mile calculator.

EV vs Gas Cost Calculator — FAQ

What is a typical EV efficiency in mi/kWh?

Most modern EVs achieve 3–4 miles per kWh in mixed driving; large electric trucks and SUVs sit nearer 2–2.5, small efficient models can exceed 4. Cold weather can cut it by 20–30%.

Why does my state change the answer?

Electricity and gas prices vary independently by state. Cheap electricity with expensive gas makes an EV a clear win; the reverse narrows the gap. Always run your local prices.

Is public fast charging included?

Only if you enter its price. Fast chargers often charge $0.40–0.60 per kWh — enter the price you actually pay most often, home or public.
