EV vs. Gas Calculator

Compare the annual energy cost of an electric car and a gas car, based on mileage, consumption and price per kWh/liter.

Annual savings with EV
$924
Compared to a gas car
EV, energy cost/year
$540
Gas car, fuel cost/year
$1,463

How to use the calculator

  1. Enter how many kilometers you drive per year.
  2. Fill in consumption and price for the EV (kWh/100 km and $/kWh).
  3. Fill in consumption and price for the gas car (liter/100 km and $/liter). The calculator shows annual energy cost for both, and how much you save with an EV.

How the cost is calculated

The calculator computes annual energy cost for each car type separately, then finds the difference:

EV cost = (Mileage ÷ 100) × EV consumption × Electricity price
Gas car cost = (Mileage ÷ 100) × Gas consumption × Gas price
Savings = Gas car cost − EV cost
Note: This calculator only compares energy/fuel cost. It doesn't account for purchase price, taxes, insurance, service, or depreciation, which should also be considered when buying a car.

Frequently asked questions

What isn't included in this comparison?

The calculator only looks at energy/fuel cost. Purchase price, taxes, insurance, service, maintenance and depreciation aren't included, but can make up a large share of total ownership costs.

Why do electricity and gas prices vary so much?

Electricity prices vary with season, time of day, region and plan. Gas prices vary with crude oil prices, taxes and local competition. Use an average for a more representative figure.

Does an EV always pay off?

Not necessarily. Energy cost is often lower for an EV, but the full picture also depends on purchase price, mileage, access to charging, and other ownership costs not included in this comparison.
