🔌 EV vs Gas Cost Calculator
Compare what it costs to drive on gasoline versus electricity — cost per mile and annual cost for each, and the yearly saving of the cheaper option.

What is an EV vs Gas Cost Calculator?
It puts two very different ways of buying energy on the same footing — dollars per mile. A gas car's cost per mile is the pump price divided by MPG; an EV's is its electricity use times your power rate. Seeing both as a per-mile number, and then as an annual total, makes the running-cost gap concrete.
The result depends heavily on local fuel and electricity prices, so plug in your own numbers rather than national averages. Remember this is the energy side only: it deliberately leaves out purchase price, maintenance, and incentives so you can judge fuel-versus-charging cleanly.
❓ Frequently Asked Questions
How does the EV vs gas comparison work?
For the gas car it divides the pump price by MPG to get a cost per mile. For the EV it takes the consumption in kWh per 100 miles, divides by 100 to get kWh per mile, and multiplies by your electricity price. It then scales both up by your annual mileage and shows the yearly saving of whichever is cheaper.
What does this comparison leave out?
It covers energy cost only — fuel versus charging. It does not include purchase price, depreciation, insurance, maintenance, tax incentives, or public fast-charging premiums. EVs typically win on both energy and maintenance but can cost more up front, so treat this as one piece of the picture.
What is a typical EV efficiency in kWh per 100 miles?
Most electric cars use roughly 28–35 kWh per 100 miles on the EPA cycle, with efficient compacts nearer 25 and large trucks and SUVs closer to 45–50. Check your model's rating; home charging losses are generally assumed to be folded into that figure.
Why can gas sometimes look cheaper here?
If you enter an efficient hybrid, cheap gasoline, and an expensive electricity rate — such as costly public DC fast charging — the gas cost per mile can dip below the EV's. Home charging on an off-peak rate is where EVs usually pull well ahead.
